In this myForest Tutorial you will learn what myForest Paid Plans are, and the benefits they bring to you as a myForest user.
myForest is free-to-use public software. In addition to this, myForest contains paid features which are designed to improve your forest creation and management projects.
In this video you will learn the difference between free and paid features, and how these paid features will improve your mapping, data collection, and planning process. Some paid features enable you to meet the requirements for some Forestry Commission, Scottish Forestry, and Natural Resources Wales mapping and planning standards when applying for grants and other processes.
In myForest you can locate your site quickly and easily using your site address or postcode.
Locating your site is one of the first steps after launching the myForest app. The live mapping view will enable you to easily map your site on the various backgrounds, and start adding detail to your forest creation or management project.
Log in (or register) to your myForest account. Once logged in, launch the myForest app (please note, this will automatically open a new tab in your web browser). Having launched the myForest app for the first time, you will be presented with the following view.
Using the locate tool in the top right corner of your screen, enter your site address or postcode.
Having entered your site address or postcode into the locate tool, click the locate (or search) button.
In this myForest Tutorial you will learn how to locate your site on the myForest live view mapping using either your site address or site postcode.
In order to begin mapping your forest creation or management project, you will first need to locate your site on the live view mapping. Once you have added mapping to your account or client, myForest will automatically load to your site in subsequent sessions.
You are able to locate your site across Britain using either a site address, or a site postcode.
You are also able to manually locate your site using the zoom and pan tools.
Mapping Backgrounds serve as a drawing template or background image. All mapping backgrounds are georeferenced ensuring your mapping (points, lines, and polygons) are accurately represented should you wish to download and use your mapping elsewhere. myForest offers a choice of several backgrounds (see table below).
| Backgrounds | Free Users | Paid Plan Users |
|---|---|---|
| Google Roads | ✔ | ✔ |
| Google Roads & Terrain | ✔ | ✔ |
| Google Satellite | ✔ | ✔ |

| OS Outdoor | ✖ | ✔ |
| OS Road | ✖ | ✔ |
| OS Light | ✖ | ✔ |
Launching myForest, your default view will show the control bar (on the left hand side) and live view mapping (on the right hand side). You are able to select your preferred Mapping Background, and pan around the map in this window.
In the green bar, found along the top of myForest, you will find the Mapping Background dropdown menu. From this menu you will be able to select your desired background as you progress through your creation and management process. Please note you can change the Mapping Background any time.
In the Mapping Background dropdown menu, you will find several backgrounds to choose from including:
In this myForest Tutorial you will learn about the different backgrounds and how to use them.
Mapping backgrounds are an essential part of all Forestry Commission, Scottish Forestry, and Natural Resources Wales compliant forest creation and management plans. Additionally, specific mapping backgrounds are required for forest creation and management grants.
Understanding how to use mapping backgrounds in myForest is key. This tutorial will cover all the key components of utilising mapping backgrounds within the software whether you have a free or paid myForest plan.

Data layers show geographical data presented in an easy to access, GIS friendly, format. myForest offers a huge range of authoritative data layers, allowing you to assess potential opportunities and constraints within your site, or adjacent to your site in the wider landscape.
Forest creation and management plans require detailed opportunities/constraints desk and field analysis to ensure interventions do not adversely impact the site or wider landscape. Furthermore, there may be several opportunities within, or adjacent to your site which are of importance or interest.
myForest offers data layers which cover Great Britain, as well as offering layers specific to England, Scotland, and Wales. These layers vary in uses from those which may be specific to forest creation or management, to generic layers useful in all cases.
All data layers offered in myForest are provided with additional guidance text, allowing you to fully understand each layer and its intended use. For all statutory documentation (templates, grants, etc) it is advised you use additional opportunities and constraints mapping software (for example Defra MAGIC, or Land Information Search). See below for further information.
Launching myForest, your default view will show the control bar (on the left hand side) and live view mapping (on the right hand side). All data layers will appear on the live view mapping as a coloured mask which will be shown in the data layers dropdown menu.
In the green bar, found along the top of myForest, you will find the data layer dropdown menu. From this menu you will be able to move between the four available tab (Great Britain, England, Scotland, and Wales). Within each tab, a list of available data layers will be displayed.

In this myForest Tutorial you will learn about data layers and how to use them.
Data layers are an essential aspect of all major forest creation and management templates and grants required across Great Britain. myForest offers a large array of data layers ranging from Great Britain wide, to England, Scotland, or Wales specific layers relevant to individual grants or processes.
All data layers are visible on the live view mapping, or can be included in pdf downloadable maps which can be used as part of project planning and applications.
It is advised to check data layer accuracy across multiple provider sites (MAGIC, Land Information Search, Map Viewer, and DataMapWales).
The MAGIC website provides authoritative geographic information about the natural environment from across government. The information covers rural, urban, coastal and marine environments across Great Britain. It is presented in an interactive map which can be explored using various mapping tools that are included.
Scottish Forestry Land Information Search - The Land Information Search (LIS) is a map based tool that allows you to search for data relating to an area of land or a feature that you have identified. Run a search in order to highlight the presence of a range of environmental features and designations such as Scheduled Monuments, Sites of Special Scientific Interest and Native Woodland that may fall within your area of interest and within a 500m buffer zone.
Scottish Forestry Map Viewer - Map Viewer allows you to explore and discover information about Scotland’s woodlands and forests. Within the application, you can select from many different map layers including: areas benefiting from Forestry Grant Scheme funding; Forestry Grant Scheme target and eligibility areas; felling permission; forest plans; Legacy Grant Scheme approvals.
DataMapWales provides geographic information and associated services. Like most Geographic Information Systems, DataMapWales allows you to search for the information you might be interested in, for a dataset to be displayed on top of a base-map, and the features of interest to be examined, measured and analysed.
During the forest creation and management process you may wish to import compartment, sub-compartment, and/or feature mapping which you have either created using an alternative software, or been provided with by a third party.
You are able to import multiple file types directly into myForest using the import tool, which is found in the control bar. You can import Shapefiles, KML and KMZ, or GeoJSON files with varying projection types quickly and easily.
Launching myForest, your default view will show the control bar (on the left hand side) and live view mapping (on the right hand side). You will be able to find the import tool in the control bar on the left hand side.
In the control bar (left hand side) open the tools section and select the import tool. A pop-up will appear explaining what the import tool is, the types of files you are able to import, and whether you would like the file to be imported as a compartment, sub-compartment, or feature.
In the import tool pop-up you will be able to select whether you would like your file to be imported as a compartment, sub-compartment, or feature. You will also be present with a choose file button, allowing you to uploaded your desired item.
Having decided the import type and uploaded the relevant file, click the green import button. Your import will automatically be added to the corresponding section in the control bar.
There are several common issues users encounter when trying to import mapping into myForest, including:
Converting multi-polygons to single polygons (shapefiles only):
myForest is not able to import multipolygons (at this stage) and as a result, users uploading shapefiles containing multipolygons may will encounter the issue where some items from within a shapefile will become visible when imported, however other aspects which would be expected do not become visible. To import mapping into myForest, you will need to provide shapefiles which contain single polygons only. For guidance on converting multi-polygons to single polygons, please refer to guidance produced by the software provider.
Single and multi-polygons are a systematic way for information to be stored within a shapefile which can then be exported and transferred. An illustration of single vs multi-polygons can be seen below.
| Single Part Polygons | Multi Part Polygons |

Setting a file projection:
How to set a file projection will vary depending on the software used to generate your compartment, sub-compartment, or feature mapping. For guidance on setting a file projection, please refer to guidance produced by the software provider. For more information on file projections please find more information below.
Both projections EPSG:4326 and EPSG:3857 use the WGS84 reference system (this is a standard approximation model of the Earth's surface. EPSG:4326 coordinates are unprojected, giving you exact locations on the WGS84 spheroid (the latitude/longitude degrees which you may be familiar with). EPSG:3857 coordinates are projected onto a flat plane. This projection type is the standard used by web maps because the projection works fairly evenly across the globe. EPSG:27700 is the OS projection. It gives a nice consistent view of the UK but it is not advisable to use this projection outside the UK.
Files containing invalid geometries:
Invalid geometries are the most complex issue users may encounter. If your file contains invalid geometries please get in touch with the myForest team via our helpdesk.
In this myForest Tutorial you will learn what the Import tool is, how to use it and how to fix the most common issues encountered by users when importing their files to myForest.
If you have used another GIS program to map compartments sub-compartments or features you are able to import them directly into myForest.
You can import your mapping in KML, KMZ, GeoJSON and ESRI shapefile formats.
RPA Land Parcels ("Land Parcels") are digitised field boundaries for all land that is registered with the Rural Payments Agency (RPA) in England.
Land parcels are essential to access government funding for woodland creation and management. They also make a great starting point for mapping in myForest, ensuring consistency and accuracy.
The process of adding Land Parcels into myForest is quick and easy. All that is needed is the Single Business Identifier (SBI) for the property.
There are two levels of Land Parcel functionality in myForest:
Users with Free Plans can import Land Parcels as a data layer, but cannot interact further with them.
Paid Plan users can convert Land Parcels into Mapping Components, allowing full flexibility and inclusion in output maps.
The Rural Payments Agency (RPA) is the only accredited paying agency in England, making payments to farmers, traders and land owners. Along with paying subsidies the RPA have a number of other roles including the Rural Land Register (RLR) which holds around 2.4 million registered land parcels digitally, and sends land maps to landowners in England.

Having mapped your compartments, sub-compartments, and/or features in myForest you may wish to export this mapping for varying reasons. Exporting your mapping is a quick and easy process, with myForest allowing you to export mapping in multiple file types using several projection types.
In providing three different file formats for exporting, we have created a versatile tool, which can function with other programs. Based upon where you intend to use the file would influence the format you might export it as. Another key difference is that GeoJSON and KML both export as a single file, whereas Shapefiles are several files which you have to zip.
You are able to export using the following file formats:
Both projections EPSG:4326 and EPSG:3857 use the WGS84 reference system (this is a standard approximation model of the Earth's surface. EPSG:4326 coordinates are unprojected, giving you exact locations on the WGS84 spheroid (the latitude/longitude degrees which you may be familiar with). EPSG:3857 coordinates are projected onto a flat plane. This projection type is the standard used by web maps because the projection works fairly evenly across the globe. EPSG:27700 is the OS projection. It gives a nice consistent view of the UK but it is not advisable to use this projection outside the UK.
You are able to export using the following projection types:
Export use:
Depending on the reason for exporting your compartments, sub-compartments, and features, we may recommend a specific file format and projection type:
| Export Use | Recommended File Format | Recommended Projection Type |
|---|---|---|
| Nonspecific Export | GeoJSON | EPSG:4326 - WGS84 unprojected |
| For use in ESRI or ArcGIS |
ShapeFile | EPSG:4326 - WGS84 unprojected, or EPSG:3857 - web mercator |
| Google Earth | KML | EPSG:4326 - WGS84 unprojected |

Having created, imported, and edited your site, compartment, sub-compartment, and feature mapping using myForest, you may wish (or need) to export this mapping for multiple reasons.
Exporting your mapping is a quick and easy process. myForest allows you to export your mapping into multiple file formats with varying projection types based on your intended use. In this video you will learn how to export your mapping, and learn about the best format and projection to use based on your next steps.
As you map compartments, sub-compartments, and features in myForest you may find that the live view mapping becomes increasingly complex. The show / hide tool allows you to turn compartment, sub-compartment, feature, and individual item mapping either on or off, changing which items are visible on your live view mapping and as a result allowing you to carry out your forest creation and management planning in a more effective manner.
Having launched the myForest app, you are able to draw several compartments, sub-compartments, and features. Over time you may find that your live view mapping becomes increasingly complex and difficult to use effectively. Using the show/hide tool you are able to reduce what is visible.
To show/hide all compartments and sub-compartments locate the compartments section in the control bar.
In the top right corner of the compartments section you will find the show/hide icon which is indicated by an eye.
To show/hide all compartments and sub-compartments, click the eye icon.

From this menu, select the show/hide mapping option.
In this myForest Tutorial you will learn about the show/hide mapping tool, and how to use it.
With most forest creation and management projects it is likely you will have multiple mapping components comprised of compartments, sub-compartments, and features which will all be visible on the live view mapping.
At times, for example when drawing additional mapping, you may wish to show or hide specific items in order to provide greater levels of clarity when doing specific tasks. Using the show / hide tool, you are able to gain this clarity by having only the items you desire visible at one time. In this tutorial, you will learn how to show / hide tool to maximise your productivity.
As you map compartments, sub-compartments, and features in myForest you may find that the live view mapping becomes increasingly complex. When you create and map new items you will be required to provide an item name (when naming compartments you will be provided with the option to also select a number; when naming sub-compartments you will be provided with the option to also select a letter - this follows standard forestry labelling procedures).
Having created and mapped a new item, you will find that on the live view mapping you will have your mapped items visible alongside an item label containing your desired title (and number/letter). You are able to move these labels to a desired location, along with the ability to to change the arrow direction. Furthermore, you are able to show or hide all labels from view in the live view mapping.
Having launched the myForest app, you are able to draw several compartments, sub-compartments, and features. Over time you may find that your live view mapping becomes increasingly complex and difficult to use effectively. Using the label tool you are able to reduce what is visible.

From this menu, select the show/hide label option.
In this myForest Tutorial you will learn about labels and how they can best be used.
Having mapped, or imported, your site compartments, sub-compartments, and features you will notice that each of these items are automatically labelled on the live view mapping.
Depending on the chosen name, number (for compartments), and letter (for sub-compartments) a label will appear on the live view mapping highlighting the name and location of the mapped item.
In this video you will learn how to move individual labels, and how to show or hide all, and individual, labels for compartments, sub-compartments, and features
In myForest all compartments, sub-compartments, and features which you have mapped will have specific geometries calculated and updated automatically. The geometries calculated include length (m), perimeter (m), and area (ha). There may, however, be instances where you do not wish to map an item in order to measure the distance between two points.
The measure tool allows you to quickly and accurately measure the distance between two specific points located on your live view mapping, through a sequence of consecutive clicks.
The measure tool is located in the tools section of the control bar.
Having launched the myForest app, you are able to measure the distance (m) between two locations on your live view mapping.
The measure tool can be found in the tools section of the control bar (bottom right of your screen).
The measure tool can be found in the tools section of the control bar (bottom right corner of your screen).
Click on the measure tool button.
Clicking on the live view mapping, mark the desired starting location of the distance you would like to measure.
As you move your cursor around the live view mapping, you will notice a measure line appear alongside a tag indicating the distance the cursor is currently (m) from the starting point.
Click on the live view mapping, mark the desired ending location of the distance you would like to measure. You will notice the distance (m) is indicated on the tag next to the marked ending point.
In the control bar, under the tools section, you will notice the measure tool now says "Reset Measure". Clicking this button will close / reset the measure tool, removing the distance you have measured.
In this myForest Tutorial you will learn about the measure tool and how it is used.
In myForest all compartments, sub-compartments, and features have specific geometries calculated and updated automatically as you carry out the mapping, and map-editing process. The geometries include length (m), perimeter (m), and area (ha). There may, however, be instances where you do not wish to map an item in order to measure the distance between two points.
The measure tool allows you to quickly and accurately measure the distance between two specific points, through a sequence of consecutive clicks. In this video, you will learn how to use the measure tool in a simple and effective manner.
Understanding how and when to use the snapping tool is essential to create detailed and accurate plans in myForest.
The snapping tool allows you to reduce mapping error through overlaps and gaps between mapped items. Snapping also enables you to map quickly, building upon your previously mapped items; this includes snapping to compartments, sub-compartments, features, RPA Land Parcels, buffers, and cut-outs. Within myForest you are able to snap to corners or edges, while also being able to adjust the level of sensitivity from 5 to 30m.
Having begun mapping a compartment, sub-compartment, or feature on the live view mapping (regardless of whether you are mapping a new item, or editing an existing item). In the control bar you will find the snapping tool. The snapping tool allows you to select whether you would like to snap to corners, edges, or turn snapping off. You are also able to adjust the snapping sensitivity.
Clicking on the snapping tool sensitivity option dropdown, it is possible to select whether you would like the snapping tool to be highly sensitive (5m) or less sensitive (30m) with varying options in-between.
Having selected that snapping should occur to existing edges, and to a sensitivity of 20 meter, while mapping the perimeter of this item the snapping options selected have allowed accurate and fast mapping to occur, while preventing overlaps and gaps in the item mapping.
In this myForest Tutorial you will learn about the snapping tool and how to use it when mapping compartments, sub-compartments, and features.
As you add more detailed mapping to your forest creation or management plan (including buffers and cut-outs), accuracy will be essential to ensuring all plans are consistent and the geometry measurements calculated automatically in myForest are correct.
The snapping tool allows you to reduce mapping error through overlaps and gaps between mapped items. Snapping also enables you to map quickly, building upon your previously mapped items. In this video you will learn how to use the snapping tool and the various snapping options offered within myForest.
Having mapped compartments, sub-compartments, and polygon features within myForest, you may wish to remove a certain interior area from an item. This could be for several reasons (for example, to remove an area which will not be planted during a creation project).
Creating a cut-out is a quick and easy process, with the relative item geometry being automatically updated based upon the new properties, e.g. compartment area (ha).
Being able to use cut-outs effectively is a key skill when creating effective forest creation and management plans within myForest where the automated calculations are required to be detailed and accurate.
To begin adding a new cut-out to a compartment, sub-compartment, or polygon feature, you will need to launch the edit mapping option.
You can select the edit mapping option by clicking on the three dots found in the row of the item you would like to edit the mapping for.
Having launched the edit mapping function, at the bottom of the control bar you will find the cut-out section.
Using the add cut-out button, you can begin drawing a new cut-out.
In a similar fashion to mapping you compartments, sub-compartments, and polygon features, you can map you cut-out using consecutive clicks on the live view mapping.
Once you have completed mapping your cut-out click back in the red circle marking where you initiated the mapping process.
At any point in time, you are able to cancel the mapping of your cut-out by clicking the "Cancel Cut-out" button found in the control bar.
Having mapped your cut-out, it will appear in the control bar, under the Cut-outs section.
You will notice the cut-out area (ha) has been automatically calculated.
You are able to edit the mapping of your cut-out in a similar way to editing any other mapping, clicking, dragging, and dropping the desired corner to its new location.
You are able to delete your cut-out at any time.
Clicking the delete button in the cut-out row you wish to delete.
You are able to create several cut-outs per compartment, sub-compartment, or polygon feature.
All cut-outs will appear in the cut-out section in the control bar.
In this myForest Tutorial you will learn about the cut-out tool, and how best to use it.

Creating a cut-out is a quick and easy process, with the relative item geometry being automatically updated based upon the new properties, e.g. compartment area (ha).
Having mapped your compartments, sub-compartments, and features in myForest you may wish to add a set distance buffer to either the interior or exterior of a mapped item.
In myForest you are able to add a buffer to the interior or exterior of any compartment, sub-compartment, or feature to a defined set distance. This enables you to quickly create accurate buffer measurements which may be used in the forest creation or management process (for example risk mitigation processes surrounding public footpaths). This buffer can be used in multiple ways depending on your intended output.
To begin adding a new cut-out to a compartment, sub-compartment, or polygon feature, you will need to launch the edit mapping option.
You can select the edit mapping option by clicking on the three dots found in the row of the item you would like to edit the mapping for.
Using the buffer colour palette found in the control bar, you are able to select a colour you would like your buffer to appear on the live view mapping as.
In the control bar you will find the buffer distance (m) function. Using this toggle you are able to either manually type the desired buffer distance, or using the arrows increase or decrease the buffer distance.
In this myForest Tutorial you will learn about the buffer tool, and how best it is used.

Having created a forest creation and/or management plan using any of the templates freely available in the myForest app, you may wish to keep an archived record of each version of the document throughout the project lifespan. Archived plans can be marked as approved by the relevant forest authority adding greater clarity to the document status.
Document version control is an integral part of carrying out effective project management and is highly advised throughout the forest creation and management process. The Archive tool allows you to store an un-editable copy of each version which is clearly dated and stored for easy accessibility and downloading whenever required.
Having launched the myForest app you will be able to add forest creation and management plans to your archive folder.
Please note that in order to add plans to your archive you must have first created a plan within the myForest app.
From the list of forest creation and/or management plans you have created within myForest, click the three dots on the item row you wish to add to your archive.
From the drop down menu select the "add to archive" option.
Depending on the type of plan you wish to add to your archive you will be asked if the plan has been approved by the relative forest authority.
Please note, if answered yes, the approved plan will be marked as such when added to your archive.
Depending on the type of plan you are trying to add, the relevant forest authority will automatically change.
Selecting the appropriate answer, click the green "add document" button.
Having added your document to the archive, your document will now be visible in the control bar under the archive section.
This document will no longer be editable, but you can download it at any time.

When creating either a forest creation or management plan it is vital to outline the Forest Management Unit (FMU). The FMU is the area subject to a forest management plan or proposal. This area is selected by the owner and/or manager and will be determined by the nature of the forest, the proposed operations and both creation and management objectives. Extensive FMUs have the advantage of allowing a strategic approach to be taken in achieving UK Forestry Standard (UKFS) Requirements, both in terms of the area covered and the timescale.
With a Forest Management Unit outlining the creation or management area (this typically includes the site's entirety) the first step you need to take is outlining compartment and sub-compartment areas. Creating both compartments and sub-compartments will enable you to begin collecting and adding detailed data which can aid your planning process while also ensuring you meet all requirements of the appropriate forest authority.
Compartments are overarching functional units within an outlined FMU, this may be a clearly defined forest (or forest creation areas) within a site, or it may be sections of a forest up to ‘hard’ features (for example a river boundary, a Public Right of Way, or an existing access road). Please note, for smaller forests (or creation areas) you may only require a single compartment.
The standard forestry convention dictates that compartments should be provided with a number (you may also include a compartment name), and sub-compartments should be provided with a letter (you may also include a sub-compartment name). Through this systematic approach, when producing maps or plans which are submitted to any stakeholder, the compartments, sub-compartments, and any plans associated with that area are clear and easy to understand.
In this guidance you will learn:
The first step in developing a compartment design is creating a new compartment (eventually leading to the creation of, potentially, multiple compartments). Creating a new compartment is a quick and easy process. For each new compartment you create, you will be required to provide either a compartment name, or a compartment number (please be aware you can create a compartment with both a name and number).
Having launched the myForest app you will be able to create a new compartment using the "Add Compartment" button found in the compartments section in the control bar.
Having clicked the "Add Compartment" button, a pop-up will appear.
In this pop-up provide a compartment name and/or number. When ready, click the green "Create Compartment" button.
Having clicked the green "Create Compartment" button, your new compartment will appear in the compartments section in the control bar.
As you create multiple compartments, a list will be formed. You are able to drag and re-order your compartments as you wish.
In this myForest Tutorial you will learn how to create a new compartment within myForest.
Compartments are overarching functional units within an outlined FMU, this may be a clearly defined forest (or forest creation areas) within a site, or it may be sections of a forest up to ‘hard’ features (for example a river boundary, a Public Right of Way, or an existing access road). Please note, for smaller forests (or creation areas) you may only require a single compartment.
In myForest you can create several compartments to begin your forest creation and management planning process.
The second step in developing a compartment design is mapping your compartment. Mapping a compartment is a quick and easy process. Please note that should you make a mistake while mapping your compartment, or should you wish to change the design of your compartment (as forest creation and management is an iterative process), you are able to edit a compartment mapping at any point.
In this myForest Tutorial you will learn how to map your compartment.
Within myForest you can map your compartment quickly and easily providing a great foundation for adding several sub-compartments and features as you progress.
In this tutorial you will learn how to map your compartment from scratch, and then also edit your compartment should you wish.
Compartments hold no forest creation or management data in themselves, rather they provide the framework for sub-compartments to be created. When developing your compartment design, you may wish to add or edit the compartment name or number. Adding or editing this compartment data is a quick and easy process.
In this myForest Tutorial you will learn how to add and edit compartment data.
This is a simple process allowing you to allocate unique numbers to, and, if required, name your compartments
Sub-compartments are discrete areas within a Compartment which are distinct in terms of their permanent boundaries (or infrastructure), their woodland type, or their management objectives. They are a fundamental concept in sustainable forest management, and are key to producing a coherent, holistic management plan.
For background information see below.
First create a Compartment. For help see https://myforest.sylva.org.uk/guidance (Creating, Mapping and Adding Data to a New Compartment).
Click on your Compartment in the control panel to open the dropdown menu, and select +add sub-compartment.
In the Add Sub-compartment popup, select the sub-compartment type: Creation, for new woodland, or Management, for existing woodland. Each sub-compartment can optionally be given a name and/or a letter, and the access type can be selected. When you have finished, click Create Sub-compartment.
The next step is to map the Sub-compartment boundary.
Click on the ⋮ menu beside your Sub-compartment in the control panel (click on the Compartment first if you cannot see your Sub-compartment), and select Add Mapping. This option changes to Edit Mapping after you have mapped a Sub-compartment.
Follow the mapping instructions in the control panel popup. Please note that areas of open space should be mapped separately - this is especially important to ensure that Inventory and Stocking calculations work correctly for both Creation and Management Sub-compartments.
For further guidance see https://myforest.sylva.org.uk/guidance (The Buffer Tool, The Snapping Tool and The Cut-Out Tool).
Sub-compartment General Data is used to record site-related information, with the ability to add custom typed records in Notes, and a visual record in Photos.
Click on the ⋮ menu beside your Sub-compartment in the control panel (click on the Compartment first if you cannot see your Sub-compartment), and select Edit General Data.
General data provides the option to record:
See the individual tippies on each tab for more help.
Sub-compartment Creation Data is used to record establishment-related information, useful for completing woodland creation plans and grant applications, as well as for planning operations, and providing a permanent record of trees planted. Data are automatically copied into the relevant sections of Creation Downloads in the control panel.
Click on the ⋮ menu beside your Sub-compartment in the sidebar (click on the Compartment first if you cannot see your Sub-compartment), and select Edit Creation Data.
Creation data provides the option to record:
See the individual tippies on each tab for more help. 
Sub-compartment Management Data is used for recording woodland-related information useful for management purposes, with the ability to add data chronologically. Data are automatically copied into the relevant sections of Management Downloads in the control panel.
Click on the ⋮ menu beside your Sub-compartment in the Compartments section of the sidebar (click on the Compartment first if you cannot see your Sub-compartment), and select Edit Management Data.
Management data provides the option to record inventory data, carry out mensuration calculations, produce felling proposals (England and Scotland) and complete a Work Programme.
You have two choices for entering your inventory data.
Either (method A),
Enter plot data to enter individual tree measurements from inventory sample plots. You will need the plot size, and the species, height and diameter (DBH) for each tree.
myForest calculates the percentages and stocking for each species, basal areas and volumes.
Or (method B),
Enter completed inventory data to enter previously calculated or estimated figures for overall species percentages, mean DBH, mean height, stocking and basal area.
myForest calculates the stocking for each species, basal areas and volumes.
See the individual tippies on each tab for more help.
Alongside mapping your compartments and sub-compartments, you may have several site features which require mapping to be included in your site plans. Depending on the type of features found within your site, you can create point, linear, and polygon features to make each is mapped accurately. Features may include site access points, public footpaths and racks, and natural features such as ponds, badger setts and more.
In this guidance you will learn:
Features are an important part of any forest creation or management plan, ensuring each feature is mapped accurately is vital to developing an effective maps and plans which are appropriate for any range of desired activities.
The first step to adding your site features to myForest is creating a new feature. As you add multiple features you are able to provide a feature name and type. Feature types include point, linear, and polygon features. Each feature type can be used in multiple ways depending on your situation. Please note, if you use a gps device to collect feature data on site, you are able to import that data via the import tool - for more information on the import tool, please refer to that section in the guidance page.
In this myForest Tutorial you will learn what the how to create a new point, linear, or polygon feature in myForest.
You may wish to map multiple, varying, site features as part of your routine management operations or for specific forest creation and/or management documents.
Within myForest you can accurately map every site feature regardless of its shape, size, or location. You are also able to import features should you have collected data while on site with a gps tool.
After creating a new feature you will need to map it. Depending on the type of feature you have created the way in which you can do this may vary however they all follow the same core principles. Should you wish to edit your mapping, you can move individual point features or edit linear and polygon boundaries with ease.
In this myForest Tutorial, you will learn about examples of types of point features and how to create and work with them.
In this myForest Tutorial, you will learn about examples of types of linear features and how to create and work with them..
In this myForest Tutorial, you will learn about examples of types of polygon features and how to create and work with them.
Depending on the type of feature created within myForest, you may wish to add notes containing information which may be useful for both creation and management of your site. Adding and editing notes and to features is quick and easy in myForest and can be done at any time.
Having mapped your compartments, sub-compartments, and features you may wish to create a downloadable PDF map. Within myForest you are able to create several maps which can be downloaded easily at any time.
When creating a pdf map within myForest all key components such as scale, north arrow, copyright requirements, and your company logo (if uploaded), will be added automatically. Ensuring that your map meets all the minimum requirements when submitting to your relevant authority.
Please note, you will be required to develop several maps as part of any forest creation and/or management grant or plan. Depending upon the end-use of each map, there may be differing requirements for map layout and content. Please refer to specific guidance for each map you may be required to make.

The UK Forestry Standard (UKFS) is the reference standard for sustainable forest management across the UK, and applies to all woodland, regardless of who owns or manages it. The standard ensures that international agreements and conventions on areas such as sustainable forest management, climate change, biodiversity and the protection of water resources are applied in the UK.
Grown in Britain is the only certification scheme that provides assurance of homegrown timber and timber products from the UK.
Only the Grown in Britain logo guarantees timber has been grown sustainably and legally in the UK in accordance with the UK Government Timber Procurement Policy and the UK Forestry Standard.
Prior to creating a Scottish Forestry compliant woodland creation plan you may be required to carry out an Environmental Impact Assessment (EIA). This requirement varies depending on the size of your proposal and any sensitivities which your site may have.
The EIA Quiz is a tool developed in collaboration with Scottish Forestry to support myForest users to quickly determine whether they are required to complete an EIA prior to submitting their woodland creation operational plan, and should one be required, the next steps they must take. The quiz contains all the necessary support and guidance to ensure users feel confident in their next steps and how to complete them. In total the quiz takes no longer than five minutes, should all the information required be readily available.

Forest Lab is a project within myForest which enables landowners and scientists to exchange information about woodlands.
We know that woodland owners and managers often express concern about how to manage their woodlands in the rapidly changing environment. Sylva Foundation and Forest Research are working together to increase knowledge exchange between myForest users and forest scientists. We have developed new tools within myForest to enable users to collect and share data from their woodlands that could help support forestry science and how the appropriate use of knowledge could benefit woodland management.
Our aim is for Forest Lab to contribute to society’s understanding of critically important issues affecting the resilience and future of our trees and woodlands. We hope that scientists will be more attune to the needs of landowners, and that landowners will be kept uptodate about emerging issues, technologies and opportunities to improve their woodland creation or management.
Specific benefits of collaboration to myForest users includes access to specialist knowledge to support site-specific management decisions. Participants will also gain information and research results directly as a result of their contributions, for example learning how their woodland’s growth or resilience might compare to others nearby.
Benefits to forest scientists are access to knowledge, information and data about many different woodlands. We are calling this project Forest Lab.
With our partners Forest Research (FR) we have developed an ‘Engagement Agreement’ which sets out the joint commitments of Sylva Foundation and FR working together with volunteer ‘stewardship scientists’ participating in Forest Lab. It outlines the general expectations of all parties, and provides examples of commitments which may exist within specific Forest Lab projects. This agreement is an important step in the sign-up process.
Please read the Engagement Agreement before signing up to any projects. You will be asked to confirm that you have read this and accept its terms on signing up to each project.
Taking part in Forest Lab is optional for myForest users. To deliver Forest Lab we collaborate with Forest Research as an external third party. Unless consent is clearly given by a user, no personal data will be shared with this or any other third party. Separate consent options are provided in your Forest Lab Account Settings. More information is provided in the ‘Engagement Agreement’ and under ‘Forest Lab settings’.
If you have not already done so, the first step is to create and map the relevant Sub-compartments for which you wish to apply for a felling licence.
For each Sub-compartment, select Edit Management Data and complete the Felling tab (see below). Refer to guidance in sections 6 - 8 of the Felling Licence Online User Guide for more information.
Refer to the relevant sections in the Felling Licence Online User Guide.
myForest is a powerful GIS (Geographical Information System) incorporating advanced digital mapping capabilities with a dedicated forestry geospatial database (geospatial means the data is linked to a location).
There are a number of key concepts related to maps and mapping in myForest:
Compartments and Sub-compartments are used to spatially sub-divide woodland into management units. The practice is a critical part of woodland management and planning, and underpins how you go about mapping your woodland and storing data. How you do it will depend on a number of factors including the scale and complexity of the site, the presence of special features or constraints, and your objectives.
Compartments are broad geographic areas of woodland, typically bounded by fixed features such as rivers, property boundaries or access tracks.
Sub-compartments are discrete areas within a Compartment which may be distinct in terms of their woodland type, permanent boundaries (or infrastructure), or their management objectives. Changes in species, age class, ground conditions etc typically form the divisions between them.
Sub-compartments are a fundamental concept in sustainable forest management, and are key to producing a coherent, holistic management plan.
A logical Sub-compartment structure is vital for collating detailed data in a systematic way, for planning operations including applying for felling licences, applying for funding, and for producing woodland management and woodland creation plans. Compartments and Sub-compartments are identified with numbers and letters, eg 1a, 4c etc.
In myForest, site-specific data are recorded at the Compartment level, whilst woodland creation and management data are recorded at the Sub-compartment level.
myForest allows a high degree of flexibility in mapping and adding data to Sub-compartments. The mapping functions are powerful and at the same time quick and intuitive. The dedicated Sub-compartment database ensures forestry data is organised systematically, with the ability to build up a chronological record over time. Many of the built-in features of myForest including management plan templates, felling licence applications and operational plans are integrated with the database allowing seamless and time saving cross-referencing.
Once you have created and mapped your Sub-compartment, you can add data to it.
For further guidance see Help & Guidance (Sub-compartment General Data, Sub-compartment Creation Data, Sub-compartment Management Data).
Having an understanding of how much timber is in your woodland is fundamental to sustainable forest management in accordance with the UK Forestry Standard. In simple terms, an accurate inventory enables owners and land managers to plan harvesting operations and prepare budgets. However an inventory can be used for many purposes.
Some of these are:
Mensuration is the measurement of trees and forests. The main parameters are land area, stocking (the number of measurable trees per hectare), basal area (the breast height cross-sectional area of all the trees on a given area), and a measurement of timber volume. Basal area can be used to assess thinning intensity, and timber volume is obviously useful to know how much useable timber could be harvested, or how much carbon is stored in the tree stems.
Because it is impractical to measure every tree in a woodland, sample points or plots are usually used to estimate the number and sizes of trees in a forest or woodland. It is important that the sample is as representative of the population of trees as possible. This can be done through stratification into areas of similar characteristics, by spacing sample locations to ensure even coverage whilst avoiding bias, and by choosing an appropriate size and number of plots for the variability of the trees over the area.
In myForest, stratification is done by sub-compartment. If your existing sub-compartments are not sufficiently uniform, you may need to re-define them.
Other parameters include growth rates, tree heights and the proportions of different species and ages.
How inventory data are collected will depend on many factors. Professional foresters can often arrive at remarkably accurate estimates based on an experienced eye. On the other hand, small woodland owners may have the enthusiasm and the time to carry out detailed measurements.
myForest offers two different ways of entering your inventory data for a sub-compartment.
From the mensuration data you enter, myForest automatically calculates:
Bear in mind that the accuracy of the calculations is dependent on the accuracy of your data!
Use this method if you wish to record the information from sample plots. For each plot you will need to record:
The following is a brief description of the plot sampling methodology:
The number of sample plots varies according to the size of the sub-compartment and the variability of the trees. The following can be used as a guide and is taken from Forestry Commission Booklet 49 “Timber Measurement”:
| Area of sub-compartment (ha) | Uniform crop | Variable crop |
|---|---|---|
| 0.5-2 | 6 | 8 |
| 2-10 | 8 | 12 |
| Over 10 | 10 | 16 |
Once you have measured all the sample plots in a sub-compartment, input the data into myForest.
myForest presents an Inventory summary for each combination of species and year planted:
myForest calculates the following on a per hectare and per sub-compartment basis:
Use this method if you are not measuring sample plots, or you already have mensuration data derived from sampling (or any other method).
Remember the data should relate to the whole Sub-compartment.
You can enter as much or as little information as you wish, however the following would normally be considered requisites:
From this information, myForest can provide estimates of:
The following optional information can also be recorded:
The volume of the main stem of a tree is a function of two basic factors: height and cross-sectional area.
Height is a relatively easy measurement to make in conifers, although in the case of broadleaves it can be complicated by the need to estimate the “timber height”, or height to the spring of the crown above which there can be assumed to be no millable timber.
Cross-sectional area varies along the stem, and taper is usually not constant. However, diameter at breast height (dbh) has been shown to be a good proxy for the mean diameter along the length of the stem.
By combining dbh with the species tariff number (a figure expressing how the cross-section of the stem varies along its length), the mean cross-sectional area can be estimated.
The Forestry Commission have published the results of mensuration, or forest measurement, research since the 1960s, in the form of complex tables and charts for the majority of tree species commonly encountered in UK forestry.
Using 21st century computing power, Sylva have now condensed the Forestry Commission data related to height, DBH and tariff number into lookup tables so that for any given combination of species, height and DBH, the volume can automatically be calculated, saving much time in manually looking up tariff numbers and consulting tariff tables.
