The current status of the global organic viticulture is discussed. The challenge of conservation of species and landscape biodiversity in the Crimea is actualized. The fauna of mites and other insects in the grape agrocenosis of the South Coast of the Peninsula is reported. Biodiversity of mites and other insects in commercial vineyards at different pesticide loads is shown. The role that wild-growing vegetation in territories adjacent to vineyards plays in the agrolandscape of grape agrocenoses is highlighted. The commonness of species diversity of predatory mites in a vineyard and on its outskirts is revealed. The possibility to rely on natural mechanisms for self-regulation of population numbers of phytophagous mites under conditions of organic viticulture is demonstrated.

This paper describes a method of determination of climatic parameters with the help of the tree-, . rings analysis.Climate is the main factor limiting capability of forest and communities in many areas of the world. By means of the tree-ring analysis it is possible to make reconstruction of many important climatic and hydrological characteristics. The basic characteristics are: temperature of air and quantity of precipitation for different seasons and for one year, anomalies of atmospheric pressure, drought repeatability and intensity; fluctuations of lake levels, the river flows; frost
