Сравнительная оценка методов при мониторинге почв в вольерах Ростовского-на-Дону зоопарка

Abstract

As a result of three years of research, differences in the ecological and biological state of soils of different functional zones of the Rostov-on-Don Zoo have been established. In 2017-2020 investigated 12 sites, including aviaries with birds, various ungulates, a recreational area and a park zone of the zoo. The soil cover in various enclosures is significantly affected by animals. It depends on the size and number of animals, their size, as well as the area of the enclosures. A significant effect of ungulates on the violation of the soil and vegetation cover, the structure and density of soil composition in the enclosures was revealed. When diagnosing and monitoring the soils of the zoo, several dozen parameters were tested, reflecting different aspects of the ecological state of the soils. As a result, a set of several indicators was established with high sensitivity and information content to the effects of animals in aviaries. From physical indicators, it is recommended to determine the density of soil addition and structurally-aggregate composition, from the indicators of biological activity, urease and phosphatase enzymes showed themselves well. Cor-relation analysis data indicate the dependence of the ecological state of soils on the load of animals in the enclosures.
