Work on Ecological Site Classification (ESC) began in 1992 following a study visit to British Columbia where a similar system, Biogeoclimatic Ecosystem Classificiation (BEC) is in use. Ecological classifications for natural forests are used around the world, however here in Britain a system has been developed for classifying both semi-natural woodlands and plantation woodlands.
The project was expanded in 1996, following a Forest Research decision to consider decision support system tools in forest ecology:
The result is a system that allows users to assess the ecological suitability of alternative forest types.
The first version of ESC was available on a CD.
Version 2 was developed into an online system, and included UK wide default soil data, elevation, and plant and soil keys.
Version 3 now incorporates future climate scenario data from UKCIP02, to allow users to incorporate future suitability into planting decisions.
Version 4 is the current version
Forestry Commission Technical Paper 20 – An Ecological Site Classification for Forestry in Great Britain, with special reference to Grampian, Scotland, established the methodology with reference to Grampian, Scotland.
