| Research Abstract |
We surveyed distribution of pyrophytic tree forests in the provinces of South Sumatra, Lampung, Central and East Kalimantan, West and East Java, and Sumba Islands in Indonesia and northern Laos. Pyrophytic tree forests are rare where primary forests were recently lost or where grassland has long been dominant, while becomes dominant where fragments of forest and grassland are distributed in mosaic. We showed a model predicting the existence probability of Schima wallichii, typical pyrophytic tree, increases as time after the original forest is disturbed and reaches 100% after 150 years. Probably Schima wallichii has gradually established disturbed lands and hardy survive through its sprouting and fast growing traits in the secondary vegetations under frequent disturbance with felling and fire. As compared to Acacia mangium and Trema orientalis, fast-growing and short-lived trees, Schima wallichii allocates relatively large amount of photosynthetic products to belowground organs in the initial stages of growth and this trait may strengthen the sprouting ability. Biomass MAI of pyrophytic tree forest ranges 3.26-10.62Mg ha-1 y-1and not significantly different from the range of biomass MAI in non-fast growing tree plantations (1.90-18.80Mg ha-1 y-1). Sprouting ability of pyrophytic tree species enables them to recover biomass fast in slash-and-burn fallowed land.
