Abstract:

The article analyzes the success of natural regeneration of woody plants in the pine forests of the green zone of the city of Tyumen. The general characteristic of 13 test areas in the forests with varying intensity recreational load is given. In total, the surveyed areas marked regrowth 10 species of trees and tree shrubs. As part of the rergrowth in addition to native species are involved and Exotic species used in landscaping the city and forest parks. It was found that the total amount of undergrowth and the nature of its distribution is weakly dependent on the structural characteristics of the tree stand, but is largely determined by the degree of recreational digression biocenosis. Shrub thickets and high abundance in the live ground cover of tussock grasses and sedges negatively affect the natural regeneration of woody plants. Special attention was paid to evaluation of the success of the resumption of the main tree species — Scots pine. The proportion of pine in the total number of regrowth on different sites varies from 0 to 88%. It is shown that recreational pine forests of green zone Tyumen in most cases not provided with enough pine regrowth.
