IMPROVEMENT THE QUALITY HIGHLY PRODUCTIVE TREES IN THE CONDITIONS PRIANGARYE
Priangarye forests are under constant pressure of human impact. As a result, forest composition, structure and productivity have become very different from the standard plus and forests, which in the past made a normative reference base for taxation, established allowable cut and cutting speed. But despite the deteriorating condition of the forests in the region, they have a high productive potential, which to date is not fully used. Areas with the presence of plus stands distributed over an area Priangarye unevenly. Under the understanding of plus trees that have increased economic characteristics, and the best in terms of productivity. Plus- stands are a valuable breeding material that increases the productivity of coniferous stands Priangarye. The need for evidence-based selection criteria and norms of standard spaces, the study of their condition, structure and growth characteristics dictated by the necessity of growing plants ecological and resource destination, characterized by high stability and productivity. In this regard, there have been studies that have revealed patterns of growth and development plus and reference stands in Priangarye.
