KEANEKARAGAMAN JENIS TUMBUHAN PADA BERBAGAI TIPE HUTAN UNTUK MENDUKUNG PENGELOLAAN ZONA RIMBA DI TAMAN NASIONAL BATANG GADIS

Abstract

As a new national park in Indonesia, Batang Gadis National Park (BGNP) needs comprehensive planning from stakeholders to manage its zonation in order to avoid mismanagement. The planning should emphasize a link between conservation rule and economics by empowering community around the national park. This research was conducted to provide information about diversities of flora in each forest types in BGNP and also alternative strategy to manage wilderness zone of BGNP. Four types of forest including montane primer forest, sub montane forest, secondary forest, and degraded land or forest were observed. The diversities of vegetation were measured at ten plots for each types of forest. The total number, diameter and height of trees at ten plots of each forest types were measured. The total numbers of sapling, seedlings, and under stories of the plots were also counted. All parameters were used to find diversity indices that include species richness, Shannon, Simpson, species abundance and similarity indices. The result revealed that 117 species were identified of which 14.5% was composed of dipterocarps species. Montane primer forest had relatively higher species diversity compared to three other forest types. The value of its species diversity ranged from 2.5 until 3.5. The value of similarity indices in all forest types is low with mean under 50%. Alternative programs which may be developed in wilderness zone include areal patrol and safety, research and development, enrichment planting on secondary forest and degraded land types, management of restricted ecotourism and also non timber forest product utilization.
