Classification of forests in Bidoup - Nuiba National Park, Lamdong province

Abstract

Forests in Bidoup - Nuiba National Park have been classified by using several classification systems which dit not characterize all forest types of the park. The article focused on developing a classification system, with mapping and description of forest types of Bidoup - Nuiba National Park. Based on the ecological view of plant population of Thai Van Trung (1999) and topography of Bidoup - Nuiba National Park (Nguyen Dang Hoi, 2009), by inheritance the current forest status maps, using satellite image interpretation, field survey and inventory methods to identify the
forest type, the study results showed that the Bidoup - Nuiba forests are diverse in structure characteristics and spatial distribution, with 7 main forest types, include: (1) Forest type of closed evergreen moisture subtropical low, medium mountain; (2) Forest type of closed evergreen moisture subtropical high mountain and warm temperate low mountain; (3) Evergreen mixed broad, needle leaf moisture subtropical low, medium mountain forest type; (4) Evergreen mixed broad, needle leaf moisture
subtropical high mountain and warm temperate low mountain forest type; (5) Sparse needle - leave rather dry subtropical low, medium mountain forest type; (6) Bamboo forest mixed species of broadleaf trees, pure bamboo forest type and (7) Plantation forest. In particular, the evergreen mixed broad, needle leaf moisture subtropical low, medium mountain forest type, mossy forest subtype and dwarf - forest subtype at altitudes above 1,700 meters are characteristics of Bidoup mountain vegetation that are rarely found.
