title: Map of Russian forest for the year 2009

description: The map of Russian forest for the year 2009 is a part of Integrated Land Information System (ILIS) for Russia (Gordov et al., 2013). It contains a land cover map (Schepaschenko 2011, 2015) and associated forest data that are based on the State Forest Register (SFR). Downscaling of the SFR regional data was accomplished using a multi-sensor remote sensing approach, geographically weighted regression and reference data obtained using visual interpretation of very high resolution imagery (Schepaschenko et al., 2019). The map contains the spatial distribution of the forest parameters including the major tree species, the average age, the relative stocking, site index, and biomass conversion factors (Schepaschenko et al., 2018). The data base has spatial resolution of 5 arc second (or ca 150 m) and contains following fields: ID_FOR - unique ID of forest<br> SPEC_MOD - tree species <br> AGE - average forest age<br> SI - site index<br> RS - relative stocking (tree density)<br> GS_ha - growing stock, m3/ha<br> bef_mn - biomass expansion factor (BEF)<br> bef_sd - BEF standard deviation<br> bcef_mn - biomass conversion and expansion factor (BCEF)<br> bcef_sd - BCEF standard deviation<br> RtS_mn - root-to-shoot ratio (R:S)<br> RtS_sd - R:S standard deviation How to cite: Schepaschenko et al.
