Abstract

Little is known about post-fire tropical montane forest succession in Indonesia. This study assessed the structure and composition of post-fire forest regrowth in Raden Soerjo Grand Forest Park, a conservation forest management unit in East Java, Indonesia. We sampled three high-severity burnt units to assess forest response across a range of post-fire recovery times and one or two fire entries. We calculated mean stems and basal area per unit area by size class (tree, pole, sapling, and seedling), tree size class distribution by species, and mean percent cover of understory by life form. We found that units experiencing short-term absence of fire and two fire entries are dominated by non-tree understory vegetation, and an inverse relationship between grass cover and sapling and seedling density, indicating that understory cover may hamper the establishment of tree regeneration. We also found higher species diversity and richness following a single fire entry. Our results provide a better understanding of early post-fire forest recovery and indicate that managers should actively monitor burned areas following fire, and plan for active restoration if non-forest vegetation dominates for long time periods (>8 years) or after a second fire entry.
