The article discusses mapping of fir- and spruce-dominated forests through the North-West Caucasus (Adygeya Republic and the southern districts of Krasnodarsky Kray and Karachaevo-Cherkessiya Republic). The project was aimed to mapping the coniferous-dominated forests and assessing the accuracy of the result; it was based on hierarchical approach, Landsat TM images, neural network method and field data. The neural network method is described in detail in the Methods section. The result was validated using the regular 2x2-kilometers network, standard error matrix and kappa. Accuracy comparing to regular network was estimated at 95.9% (kappa 0.81). Dark-coniferous forests occupy 236.9 KHa (about 12% of total region’s forests). The biggest areas of coniferous forests are concentrated in Krasnodar Region due to its vast territory, while Adygeya and Karachaevo-Cherkessiya are leading in terms of relative area of coniferous forests. The presented methodology is based on available data and software and can be reproduced in other regions. The results are useful for mapping and characterization of forest type groups or for analysis of topographic factors of coniferous forests distribution.
