The aim of the study is to carry out the management and economic evaluation of the Scots pine Pinus sylvestris L. forest stand in Mezaparks, Riga. The aim of the landscape selective cutting is to improve the resilience of mature stands, while increasing the visual attractiveness of the stand. Riga?s Mezaparks has been used for recreation and other social activities for long time. To continue serving social, ecological, economical and other interests of the city, it is important, especially for the urban forestry, to define the management plant that works for it. While the study, data was collected from 132-years-old Scots pine stand of 2.47 ha, where the selected landscape cutting is planned. Th e vegetation of the stand was characterized by the use of Braun-Blanquet method. In order to characterize growing trees and dead wood, the diameter was measured for all trees above 5 cm, as well as for all the snags, their height and the species were determined. For the logs their length, and their middle diameter was measured, and the species were determined. Using the description of the selected landscape cut, all the felled trees and the economical activities for the felling were determined. The obtained data was used for calculating stand tree stock, basal area, species distribution, and the amount of dead wood. The trees according to their species were divided into diameter grades to characterize the stand. Using the computer program Mezaverte the trees were divided into assortments and their value was calculated, the data of Central Statistical Bureau was used to calculate felling costs, which resulted in the calculation of profit.
The study included 1247 growing trees, 58 snags, 11 logs, the height was measured for all the growing trees and all the dead trees. 10 tree species were identified. The composition of the plant species in the stand showed the processes of eutrophication and synantropisation of vegetation. It was found that the amount of dead wood (3.69 m3/ha) is much smaller compared to the average. By calculating the amount of wood obtainable from selected landscape cutting, it was concluded that there would be 474.85 m3 of stock, which is 34.74% of the total stand stock. It has been concluded that with the landscape selective cutting it is possible to achieve the goals set for it and while managing it to get profit.
