Summary The NFI definition of woodland is a minimum area of 0.5 hectares under stands of trees with, or with the potential to achieve, tree crown cover of more than 20% of the ground Areas of young trees, which have the potential to achieve a canopy cover of more than 20%, will also be\\ninterpreted as woodland and mapped. The minimum width for woodland is 20 m, although where woodlands are connected by a narrow neck of woodland less than 20 m wide, the break may be disregarded if less than 20 m in extent. Intervening land classes such as Roads - all 'tarmac' roads should be excluded from the woodland area, but\\ninternal forest tracks, farmers tracks, rides etc. will be included as part of the woodland if < 20m wide. Rivers - where the gap in woodland is 20m then rivers will be excluded from the woodland area. Power lines etc. - where the gap in woodland is 20m then power lines will be excluded from the woodland area. Railways - all normal gauge railways should be excluded from woodland. Scrubby vegetation is included within this survey where low woody growth seems to dominate a likely woodland site. The definition of an open area is any open area that is 20m wide and 0.5 ha in extent and is completely surrounded by woodland. The woodland boundaries have been interpreted from colour aerial ortho-photographic imagery. For the base map, photographic images aimed to be no older than 3 years at the time of mapping (i.e. areas mapped in 2007 would be based on photographs that were ideally taken no earlier than 2004). As the map is be the basis for a longer rolling program of sample field surveys it has been necessary to develop procedures to update the map to the date of the field survey, currently 2011, for the purpose of reporting on the current phase. The map is continually updated on an annual basis. These updates will are achieved by a combination of remote sensing and updated aerial imagery analysis for changes in the woodland structure and with reference to available new planting information from grant schemes and the FE sub-compartment database. Ordnance Survey MasterMap® (OSMM) features have been used as a reference for capturing the woodland boundaries. OSMM is the most up to date large-scale digital map of GB providing a seamless database for 1:1250, 1:2500 and 1:10000 survey data. All woodland (both urban and rural, regardless of ownership) which is 0.5ha or greater in extent, with the exception of Assumed woodland or Low density areas that can be 0.1ha or greater in extend, as been mapped Woodland that is less than 0.5ha in extent will not be described within the dataset but will be included in a separate sample survey of small woodland and tree features. The primary objective is to create a new digital map of all woodland in Great Britain using O.S.MasterMap features as boundaries where appropriate. The map shows the extent of all woodland of 0.5 ha. Woodland categories are defined by IFT (Interpreted Forest Type) values. Detailed Woodland categories are: Broadleaved Conifer Felled Ground Prepared for New Planting Mixed - predominantly Broadleaved Mixed - predominantly Conifer Young Trees Coppice Coppice with Standards Shrub Land Uncertain Cloud or Shadow Low Density Assumed woodland Failed Windthrow/Windblow Non woodland categories are defined by the IOA (Interpreted Open Area) values. Detailed Non woodland\\ncategories are: Agriculture land Bare area Grass Open water Other vegetation Power line Quarry River Road Urban Windfarm A full list of att6ributes can be found in the Data Lineage section.\\n\\n Any maps produced using this data should contain the following Forestry Commission\\nacknowledgement: "Contains, or is based on, information supplied by the Forestry Commission. \\n© Crown copyright and database right [Year] Ordnance Survey [100021242]".

Forest Reproductive Material (FRM) is the generic name for the seeds, cones, cuttings and planting stock used in forest establishment. The 46 tree species and the genus Populus (including aspen, black poplar and grey poplar) covered by the Regulations are known as the “controlled species”. The Forest Reproductive Material (Great Britain) Regulations 2002 regulate the marketing of FRM. These Regulations came into force on 1st January 2003 and implement EC Directive 1999/105. The Forestry Commission is the Official Body that is responsible for the FRM Regulations in England, Scotland and Wales. The Forestry Commission maintains the National Register of Approved Basic Material for Great Britain (The National Register). Each entry of basic material (or unit of approval) in the National Register is given a unique register reference that encodes: Species name Type of basic material Category of reproductive material to be produced Region of provenance Native seed zone (where appropriate) Altitude zone (if the species is native to GB) Origin (that part of the species’ natural range from which the material derives). The attributes of each polygon in this dataset are restricted to the National Register Identification Number (NRID), a national grid reference (NGR), a Basic Material 'category' symbol and the land area, in hectares. All other details mentioned above are available in the National Register. Basic Material is the plant material from which the Forest Reproductive Material (FRM) is derived and includes seed stands, seed orchards, parent material held by tree breeders in archives, individual clones and mixtures of clones. There are six types of basic material: Seed sources: This covers all material from a single tree to any collection of trees within a region of provenance or seed zone. Stands: Specifically identified areas or groups of trees with identified boundaries . Seed orchards: Sources based upon known individuals derived from tree breeding. Parents of families: Sources based upon known individuals derived from tree breeding. Clones: Individually identified trees from which the FRM will be produced through vegetative propagation . Clonal mixtures: Individually identified trees from which the FRM will be produced through vegetative propagation. Forest Reproductive Material (FRM) is cones, fruits and seeds, all parts of plants obtained by vegetative propagation, including embryos and plants produced from any of these. Normally, only FRM that comes from registered basic material can be marketed. There are four categories of reproductive material according to the basic material from which it is collected and these are recorded in this dataset: Source identified FRM (symbol SI): Comes from general or specific locations within a single region of provenance or seed zone altitude band in which no specific superior qualities are recognised. Selected FRM (symbol SE): Collected from stands showing superior characteristics, e.g. better form, growth rate and health. Qualified FRM (symbol QU): Derived from the selection of superior individual trees which have not undergone any form of testing. Tested FRM (symbol TE): Derived from the selection of individual trees or stands that have undergone evaluation for genetic quality or have been shown to be superior, in comparison to accepted standards.

GB_ROADS is compiled from Forest road network data managed by Forestry Civil Engineering. The data relates to forest road Classification. Forest Roads are categorised on the basis of intended usage (as listed below) rather than the specification used in their construction or upgrading. This can mean that, at a particular point in time, a Class A main road or a Class B spur road may have specification features that could limit its use. Class A - Main Roads Principal timber haulage route on a long-term basis. Constructed to high specification. Maintained to a high standard. Limiting features shown on road map. All year but not all weather. Class B - Spur Roads Used by timber haulage lorries for specific operations. Full geometric and safety standards for stated use. Specification tailored to suit purpose. Possibility that surfacing not high quality or durable. Long term maintenance minimal. Each usage subject to individual engineering assessment. Limiting features noted for each particular contract. Class C - Other Roads Roads other than Main or Spur roads. Maintenance dependent on usage. Not normally used by timber haulage lorries. Use by timber haulage lorries subject to the same individual engineering assessment as Class B roads.

All organisations hold information about the core of their business. The Forestry Commission holds information on trees and forests. We use this information to help us run our business and make decisions. The role of the Forest Inventory (the Sub-compartment Database (SCDB) and the stock maps) is to be our authoritative data source, giving us information for recording, monitoring, analysis and reporting. Through this it supports decision-making on the whole of the FC estate. Information from the Inventory is used by the FC, wider government, industry and the public for economic, environmental and social forest-related decision-making. Furthermore, it supports forestrelated national policy development and government initiatives, and helps us meet our national and international forest-related reporting responsibilities. Information on our current forest resource, and the future expansion and availability of wood products from our forests, is vital for planners both in and outside the FC. It is used when looking at the development of processing industries, regional infrastructure, the effect upon communities of our actions, and to prepare and monitor government policies. The Inventory (SCDB and stock maps), with ‘Future Forest Structure’ and the ‘rollback’ functionality of Forester, will help provide a definitive measure of trends in extent, structure, composition, health, status, use, and management of all FC land holdings. We require this to meet national and international commitments, to report on the sustainable management of forests as well as to help us through the process of business and Forest Design Planning. As well as helping with the above, the SCDB helps us address detailed requests from industry, government, non-government organisations and the public for information on our estate. The FC’s growing national and international responsibilities and the requirements for monitoring and reporting on a range of forest statistics have highlighted the technical challenges we face in providing consistent, national level data. A well kept and managed SCDB and GIS (Geographical Information System - Forester) will provide the best solution for this and assist Countries in evidence-based policy making. Looking ahead at international reporting commitments; one example of an area where requirements look set to increase will be reporting on our work to combat climate change and how our estate contributes to carbon sequestration. We have put in place processes to ensure that at least the basics of our inventory are covered: 1. The inventory of forests; 2. The land-uses; 3. The land we own ( Deeds); 4. The roads we manage. We depend on others to allow us to manage the forests and to provide us with funds and in doing so we need to be seen to be responsible and accountable for our actions. A foundation of achieving this is good record keeping. A sub compartment should be recognisable on the ground. It will be similar enough in land use, species or habitat composition, yield class, age, condition, thinning history etc. to be treated as a single unit. They will generally be contiguous in nature and will not be split by roads, rivers, open space etc. Distinct boundaries are required, and these will often change as crops are felled, thinned, replanted and resurveyed. In some parts of the country foresters used historical and topographical features to delineate sub-compartment boundaries, such as hedges, walls and escarpments. In other areas no account of the history and topography of the site was taken, with field boundaries, hedges, walls, streams etc. being subsumed into the sub-compartment. Also, these features may or may not appear on the OS backdrop, again this was dependent on the staff involved and what they felt was relevant to the map. The main point is that, as managers we may find such obvious features in the middle of a sub-compartment when nothing is indicated on the stock map, while the same thing would be indicated elsewhere.
