Diversity and the condition of green spaces and woody plants in 3 Lithuanian cities

Abstract

<p>In urban areas, the ecological quality of life of the residents is determined by existing greenery. Municipalities aim to ensure that each city has a sufficient area of greenery, and that woody plants are healthy and suitable for that area.The inventory of green areas and woody plants provides municipalities with knowledge about the diversity, condition, and abundance of plant species, and helps organize management and maintenance.<p/> <p>The aim of the study is to assess the diversity of woody plants, health status, and abundance of greenery in 3 Lithuanian cities.<p/> <p>The inventory of greenery was carried out in 2022, in 3 cities located in different region of Lithuania: Pakruojis, Švenčionys and Birštonas. The area of public parks was calculated, the species and condition of each woody plant was determined, plant heights and trunk diameters were measured.<p/> <p>The results showed that all cities have more parks areas than the proposed minimum area. Woody plants of alien species dominate, but the number of native individuals is much higher than that of trees of alien species. Shrubs are grown less than trees. Invasive woody plants grow in all cities, of which ash maples are the most common. Most of the plants are in good condition. <p/>
