The state protective forest belt Penza-Kamensk is an important component of the ecological framework of the territory, where it is included in the system of protective forest plantations and contributes to the transformation of the steppe agricultural landscape into an agroforest landscape. The purpose of the research was an inventory and assessment of the state of forest protective plantations in order to preserve and restore the agroforest reclamation fund. In office conditions, up-to-date cartographic material was created on the basis of satellite images of high and ultra-high resolution, visual interpretation was carried out with the compilation of a vector polygonal layer of the current location of protective forest plantations, the number of decoded objects was determined. Visual interpretation of space images made it possible to identify disturbed areas of forest belts, in which the sparseness (fragmentation) of the forest stand is noted. At present, forest stands of pedunculate oak (62.0% of the forested area) dominate in the plantations of the forest belt in terms of species composition, the second place is occupied by birch (22%), pine, larch and spruce by 12%, willow - 2%, aspen and ash - by 1 %. Artificial plantations in most of the area have an average density of 0.7-0.8, which indicates a qualitative selection of the main forest-forming species in relation to soil conditions, on the one hand, on the other hand, the correct choice of the type of crops and the required planting density, taking into account the survival rate and preservation of plants at all stages of forest growing. Preservation of plantings is high, fluctuating within 75-85%. In general, the state of plantings is satisfactory.
