The article views the resources of nut pine in Khanty-Mansi Autonomous Area. The aim of the research was to give a more precise estimation of the nut pine resources basing upon the determined eco-biological characteristics of Siberian nut pine both in the entire Khanty-Mansi Autonomous Area and its administrative districts individually. The calculation of the nut pine re- sources was carried out on the basis of the preceding forest surveying data, as well as on the direct examination of cedar forests. Nut pine forests cover 4347757 ha of the territory of Khanty-Mansi Autonomous Area, among which 21.7 % (941186 ha) are nut-bearing trees. The squares of nut-bearing forests differ from one forest district to another. The taxation structure of nut-bear- ing forests is characterised by quite low indexes: the average proportion of nut pine — 4.3, average age — 200 years, average quality class — 4.0, average density — 0.54. The density slightly differs within the subzones and forest districts. The average productivity within the subzones fluctuates from one forest district to another: in the northern taiga from 41.6 to 53.8 kg/ha, in the middle one from 53.0 to 65.0 kg/ha. The higher productivity in the middle taiga (with the average yield of 57.8 kg/ha) in comparison with those in the northern one 48.4 kg/ha can be explained by the improvement of forest growth conditions within the examined region while moving from the North to the South. Biological resources of pine nut in Khanty-Mansi Autonomous Area in the years of average yield amount to 49651 t, in the north taiga it amounts to 32806 t and in the middle one — 16845 t. The nut pine reserves differ from one forest district to another.
