ENVIRONMENTAL STUDIES IN THE PARK

 

The problem of the protection of nature and species diversity of natural communities Yaroslavl as well as in other regions of Russia requires the active participation.

Urban green spaces are an important part of the city the landscape is an important part. Trees and form diversity and the views of the external forms of the monuments in the ensemble last give the urban environment a unique atmosphere. [1,2]

The park is unique in its social value. Now this - surviving in the city area of ​​active rest citizens and children. It is also important that the green zone can become a platform for scientific and practical environmental activities school district and the city as a whole. The number of species, so the questions to describe the plant communities of flora of the park is reduced each year remain relevant and necessary for the development of evidence-based recommendations for its conservation and use. Ongoing projects - a system of ecological and practical work, at implementation of which can be carried out systematic monitoring environmental status of its territory and practical work on it recovery. [3-7]

The purpose of research - to conduct geo-botanical studies of biodiversity of plant communities of the park in Yaroslavl. To formulate conclusions and recommendations for the conservation of biodiversity of vegetation.

Objectives of research - to analyze the vegetation green area of ​​the city.

The practical significance - has matured the need to perform a description plant communities of the territory in order to preserve it and landings inclusion in the data bank of the city, as well as for possible assignment status protected area of ​​the object. [8-10]

The park is dominated by the stand studied 15 tree species, of which the dominant position is occupied by a European linden - 28 copies, which, thanks to its decorative properties and the spherical shape of the crown a positive fit in the garden and park ensemble. In addition, quite common in the park such species woody plants like Betula pendula, balsam poplar, apple Forest, Acer platanoides, white willow.

Ornamental plants is determined by their state of health, which is composed of the state of a tree trunk and crown of the tree, the presence of vices, rotten knots damage. The sanitary condition of trees reduces their living condition, and eventually breaks decorative and aesthetic properties.

The largest number of trees growing in the garden are 2 class state - that is, in need of pruning, namely the lower dead branches. Dry dead branch with further decay and decomposition may serve as a nidus for the development of various infections and diseases of the tree. [9-12]

Gnarled tree rather sharply spoils the overall decorative characteristic wood and reduces its durability and quality.

Individual trees have cracks or minor violations of the cortex, whereby the estimated 3 class status.

Some of the trees assigned to Class 4 status by virtue of the crown fracture leaves with symptoms of chlorosis, settling pore fungi.

Healthy trees have no external signs of damage.

Defective trees are completely dry and we recommend that you remove them.

The findings lead to the following conclusions: Wood garden plantings are quite diverse, which only enriches the city environment. The sanitary condition and decorative garden trees in certain depend on the type of planting. Overall condition of crops in generally poor, and measures required for care.

Matured the need to preserve this unique landing a natural site and included in the data bank of the city, as well as create the preconditions for the possibility of assigning protected area status the object.
