Abstract. The article presents the results of researches of influence of recreational loads on the state of pine forests of the State National Natural Park (SNPP) «Burabay». Objects of research are high–density pine forests of age class V–VI, which grow in very dry, dry and fresh (forest type ‒ C3 and C4) forest site type in various functional zones (FZ). According to the analysis results observed the general tendency of decrease index of vital status of pine forests with the increase in the degree of recreational loads. The increase of recreational loads to an increase in the number of damaged trees and reduction in the number of healthy trees. The increase in recreational loads, result in an increased in number of damaged trees and decrease in the number of healthy trees. In active visits zone (FZ–I) number of trees category of «weakened» in 1.4–1.6 times more in compared with moderate visits zone (FZ–II) and 1.6–1.8 times more than in the control zone (FZ–III). With a decrease of edaphic moistening degree, the fraction of «weakened» and «greatly weakened» trees in the active visit zone (FZ–I) increases by 1.4–1.8 times. With a decrease in the degree of recreational impact, there is a decrease in the fraction of trees I and II Kraft class (Kraft dominance class) and an increase in III and IV Kraft class. It is found that at increasing recreational load accelerates the process of natural thinning of the pine forests in the active visit zone (FZ–I). In the control zone (FZ–III) determined a significant number trees of small stage of the thickness, whose condition is estimated as «weakened» and «greatly weakened». On based on the evidence found, devised forest management activities aimed to reduce the recreational impact on pine forests in the active visit zone (FZ–I), to prevent their further digression, as well as to at improving the recreational sustainability and conservation of the aesthetic appeal of pine forest in the recreational zones.
Keywords: pine forests, forest site type, functional zones, pine forests condition.
