METHOD FOR OPTIMIZATION OF PHYTOCENOSIS MEDIUM IN UNIQUE WOODY PLANT HABITATS Russian patent published in 2006 - IPC A01G23/00 A01G23/02 

FIELD: retention of unique dendrolara.

SUBSTANCE: method involves determining type of habitat and extent of development and suppression of unique plant; measuring height of unique plant and share of sector of free development of crown; optimizing phytocenosis medium within circular area in the center of which unique plant grows, with radius of circle being 1.05-1.2 of the average height of stock of trees; cutting off or banding only aboveground vitally active parts of tree competing with unique specimen, said parts being arranged in zone above maximally admissible height and values of which parts being determined for each competing tree from the formula: h=H.e^x, where h is distance in vertical plane from horizontal plane extending through unique tree trunk base center to points through which cutting or banding plane of aboveground parts of competing tree is extending, or maximally admissible height of arrangement of vitally active parts of competing tree, m, said cutting-off or banding procedures being performed when h value is less than height of competing tree; H is height of tree, m; e is base of natural logarithm, e=2,718281828459...; x is variable factor for various unique kinds and types of habitat, determined from formula: where V is factor of availability of space for free crown development of unique tree in horizontal plane within concrete habitat, share of crown free development sector, said factor being determined by total value of sectors occupied with projections on horizontal plane of trees surrounding woody plant and sectors non-occupied with said crown projections; J is angle between vertical line and straight line extending from unique tree top onto point of projection of competing tree trunk base center on horizontal plane extending through unique tree trunk base center; a, b, c are coefficients whose values are selected from Table 1 where unique tree kinds and types and habitats are indicated or where a, b, c are coefficients whose values are selected from Table 2 where unique woody plant kinds and types and habitats are indicated.

EFFECT: provision for creating of phytocenosis optimum for unique woody plants, minimum damage and technological effects upon woody plant.
