Assessment of soils and green stands in the recreational areas with different land-use history in New Moscow

Abstract

Abstract. Recreational areas contribute considerably to the establishment of sustainable and comfortable urban environment. Green stands and soils of recreational areas provide important environmental functions and ecosystem services, their utilization depends on natural and anthropogenic factors distinguished by land-use history. For the case of the recreational areas of New Moscow, a comparative analysis of trees (n=1909) and soils (n=39, 0-10 cm layer) of the parks, established on former forested and fallow lands, was performed. It was shown that the species diversity was higher although the tree condition score was lower in the forest-parks, compared to the parks established on former fallow lands, which were generally characterized by a higher level of maintenance. Soils of these parks had a neutral pHH20 (7.20.8) and high content of organic matter (8.52.5 %), whereas the forest-parks soils were similar to the natural Retisols of the forest area with pHH20 6.40.2 and 5.10.2, organic matter content 5.90.2 и 3.50.2 %, respectively. Soils of the parks, established on the former fallow lands, had also a higher pollution level by particular heavy metals as well as considering the integral pollution index. Thus, a higher level of maintenance of the parks established on former fallow lands coincided with a higher anthropogenic pressure and ecosystem alteration. However, reorganization of forests into forestparks allowed partial preservation of the natural ecosystems. That is necessary to consider for planning the new urbanized areas in Moscow.
