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.

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]".

Each site has three common treatments: a control (C), a compacted treatment (T), a compacted and decompacted treatment (D), and more specific ones, locally decompacted soil (P) at Azerailles 54, and, limed (A) and limed and compacted (CA) at Clermont en Argonne 55. Each treatment plot of 0.25ha is replicated three times (3 blocks). Azerailles site was installed in spring 2007 and Clermont in spring 2008. Since that time monitoring occured for: -mesoclimate: rainfall, air temperature, relative humidity, bulk deposition (continuous recording) - soil climate: soil moisture (TDR Trase system (5 replicates at 15 and 60 cm depth) in one replicate of C and T (recorded each four hours) - water table: 2 piezometers in each replicate of treatments (Divers hourly recorded); monthly sampling using specific devices for Redox problems - weakly fixed soil water: cup lysimeters inserted at 15 and 60 cm depth (4 replicates in one block for C and T treatments) + teatments A and CA at Clermont en Argonne. Automate for constant vacuum at 700hP. Monthly collection for chemical analysis - soil gas: specific captors installed at 5, 10, 20, 35, 50 and 70 cm depth in each C and T treatments of the 3 blocks in the 2 sites. Monthly collection for chemical analysis (N, CO2, CH4, N2O, O2) -soil solid phase: soil morphology, soils physics, chemistry and biology (pro parte) were initialy described. Soil physical parameters (strengh, bulk density, hydraulic conductivity, swelling/shrinkage, porosity...), chemistry (C, N, exchangeable cations, P) and biology (earthworms) are perediodicaly investigated (each year for physics; 2/3 years for chemistry and biology). vegetation: both understorey and oak plantation were annually observed soil biology: earthworms are periodically observed

The ambition of the XYLOSYLVE platform is twofold, to constitute a visible forest research facility for setting up innovative forestry practices and to build a scientific infrastructure of national and international interest for terrestrial ecology. XYLOSYLVE is an ensemble of three long-term complementary field experiments and laboratory facilities associated with. Each experiment is spatially distinct from the other but all are co-located in the INRA Hermitage area close from Bordeaux city. The experiments are designed to testing forest management alternatives dedicated to biomass and wood production in Atlantic conditions as follows: 1) Three large plots (8ha) are manipulated according to three management alternatives (Pine-Eucalypt mixture, pure enhanced Pine variety and environment-friendly Pine standard) and equipped with automated instrumentations for monitoring biogeochemistry in the different compartments of ecosystems (soil, soil solution, vegetation, atmosphere). The equipment and protocols implemented are installed in collaboration with the ICOS project according to common quality assurance standards (ICOS site Class 3). These 3 plots are not replicated here. 2) A fully randomised 4-blocks experiment includes the same three treatments than above and 5 additional treatments including various levels of species mixture, fertilisation, soil preparation and legumes introduction. The 32 plots are further split according to no till - deep tillage to a total of 64 subplots each covering 0.12 ha to a total of approximately 40ha. 3) The third experiment includes 2 levels of fertilisation (control - full annual NPK inputs), 2 levels of irrigation (control (rainfall) - daily irrigation at PET) and 2 species (local Pine species - Eucalypt hybrid) replicated in four blocks and covering an area of 8 ha (plot unit ~0.25ha). XYlosylve serve as a long term research and experimental site for temperate planted forest systems in close connection with a regional network of forest experimental sites where feasibility of new forest management alternatives is evaluated. The interest of XYLOSYLVE is double: - Allow the long term monitoring of the functioning of biophysics and biogeochemistry of new forest ecosystems with high production potential. Offer to the scientific community and to the forest-based industry a common platform to gather scientific data and wood samples and test ecosystems to better understand their dynamics and their environmental impacts; - Assess durability and environmental performance of various management options for dendro-biomass production systems (symbiotic nitrogen fixation, phosphorus uptake, long term fertility, water and energy use efficiency, evaluation of vulnerability to biotic risks /insects, pathogens/ and abiotic risks/wind, drought/ …).

The site of Montiers, localized at the boundaries between Meuse and Haute-Marne departments, North-East of France, has a large surface area (143 ha). It comprises two soil successions (toposequence) and the climate, stand conditions (age, species, forest management) are equivalent on all the surface of the site. The facility comprises three biogeochemical stations of 10 000 m2 each and one flux tower above forest canopy (45 m-high) settled along a soil succession representative of soils of the region. The three stations include four substations of which three are strongly equipped and one is free for future experimentations. Each equipped substation comprises lysimeters at different soil depths (litter, -10 cm, -30 cm, -60 cm and -90 cm; 3 replicates in general), tensio-lysimeters (-10 cm, -30 cm, -60 cm, -90 cm and -120 cm; 3 replicates in general) and temperature and moisture probes at different soil depths (-10 cm, -30 cm, -60 cm and -90 cm; 4 replicates), litterbags (6 replicates), stemflows (6 replicates), gutters (4 replicates). These stations allow to follow-up on the long term the flows of water, and major (Ca, Mg, K, Na, P, Fe, Mn, Si, Al, S, C, N) and trace (Cl, Se, B, I, Cs) elements between the different compartments (soil, tree, atmosphere) of a beech forest. Each station is settled on a different soil type, i.e., alocrisol, calci-brunisol, rendosol thus allowing to assess the impact of the soil type on biogeochemical cycles and on tree growth. The flux tower is equipped with a Eddy Covariance system (CO2, H2O, and sensible heat) and a complete set of sensors recording the aerial and edaphic meterological conditions, the phenology and the canopy status. The data from flux tower are available on demand. The forest mainly consists in a beech timber of about 50 years: dominant species and forestry in the region. The effect of the soil on the biogeochemical and biological functioning of this beech forest is dealt with a very integrated approach (ecophysiology, microbiology, soil science and biogeochemistry). In addition, the flux tower permits to measure, at various levels of the canopy and above, meteorological parameters (temperature, radiation, and precipitation), the gaseous exchanges and the particular deposits.
