Stroganova, V.A. Terekhova, N.V. Mitrofanova Some soil characteristics of several botanical gardens in Moscow and Saint- Petersburg (Russia) were studied. Protected area regime, regular horticultural activities, constant invasion of soil fauna and bacteria with plant roots and soil, anthropogenic infl uence for decades and centuries altogether cause development specifi c soils. These soils are very different from both natural and urban green area (recreation parks) soils. Specifi c ways of botanical garden soil development are proved by its morphological and chemical characteristics as well as abundance and species composition of soil mesofauna. Botanical garden soils have the specifi c structure of the soil profi le, high concentration and biomass of soil mesofauna, deep bacteria penetration through soil profi le. Mesofauna and bacteria of botanical garden soils include common species of undisturbed podzolic soils as well as typical species of man-made soils. We suggest considering urban botanical gardens as the unique man-made ecosystems where negative impact of an urban environment is partly compensated and high level of biodiversity presents. We discuss the use of soil biota and botanical gardens’ ponds as a source of test culture for ecotoxicological research. Key words: botanical garden, urban soils, recreazem, hortisol, conservation of biodiversity, soil restoration, soil micromyces, soil mesofauna.
