Rare tree species of the VNIILM dendrological park in the town of Pushkino, Moscow region

Abstract

The rare trees conservation, growth and condition of the VNIILM
dendrological park in the city of Pushkino were studied in order to improve the
biodiversity of first group parks and forests of populated areas of the Moscow
region. This park was established in 1960. The park's plantings represent the
following structures of a single tree species: 1) arrays of 0.05 to 0.2 acres; 2) alleys;
3) groups of mostly ten trees each. The predominant part of the park is formed in
the form of trees planted in groups. Trees in arrays and alleys have been found to be
best preserved and growing. Some of the species planted in trees groups have
disappeared completely. Only a few rare species, including silver maple, hemlock,
white pine, black locust and Virginia bird cherry, have managed to adapt well to the
unusual growing conditions of sandy loam soils in urban areas. It is recommended
to use the above-mentioned introducers in the forests of the first group in order to
improve the biodiversity. In addition, a natural hybrid of common cherry and
Virginia cherry is of particular interest in terms of expanding the range of tree
species in the parks.
