Greenspaces are an important component of the complex ecosystem. Trees and green spaces are also very important to human well-being as well. It is widely known that trees and green spaces give environmental, social, economic and psychological benefits. For example they affect microclimates to reduce the heat effect, improve air quality. Understanding the relationship between population size and the quality and quantity of green spaces is vital for the sustainability, health and resilience of areas. Analysis of the current situation of the trees and shrubs greenery area in Klaipeda County was accomplished. The study also provides the trees and shrubs greenery area changes analysis in Klaipeda County and in the municipalities of the county. In Klaipeda County the area under trees and shrubs in 2002 was 4,758.14 ha. In 2022 the plantation area amounted to 10,793.50 hectares. From 2002 to 2022 the area of tree and shrub plantations in Klaipeda County increased by 6,035.36 ha or 127 percent. The development of plantation areas has been positively influenced by the creation of an appropriate legislative framework and the implementation of plantation programmes in municipalities.

Taking into consideration all the data of collectibility of land payments (land tax and rent), the dependence of collectibility of land payments on economic and geographical factors is analysed in municipalities of the Samara region. The factors are defined with the help of mathematical methods, which are closely associated with payments growth from the land area of a municipality and the number of residents. The dependence simulation of the level of land payments on geographical and demographic characteristics has been implemented in a municipality. This model allowed allocating ”normative level” for each municipal district which corresponds to the result of the ”average area” with given objective characteristics. This assessment allowed the authors to identify the areas with high and low levels of land payments collectibility. The efficiency assessment of municipality local governments in the Samara region on land management is made taking into consideration objective factors that limit their opportunities.
