Document Summary

Disturbance: removal of vegetation either by natural means or human activities. Succession: changes in vegetation structures and species compositions following disturbance: stages of stand development. Increased number of vascular epiphytes and large logs(still rare) Pioneer species are mostly present in canopy now. Canopy trees continue gain variety in sizes. Seeds are larger, animal and gravity dispersed. Canopy structure becomes variable with frequent gaps(emergence layer) Large lianas, vascular epiphyte, large logs and very large trees are common now. Pit-and-mount topography instead of a level land surface: arrested succession: when a forest rarely go beyond an early succession stage. Due to natural interruption, ex: continuous flooding: some vertebrates need primary forests: Show large declines in secondary forests: maybe they need pioneer species, need big, open areas, need lots of sunlight. Woodpeckers, bats, geckos: applied tropical succession. Restoring peat swamp forests: peat: accumulated non-decomposed organic matter. Threat: oil palm, shrimp farms and peat fires. Clearing for oil palm plantations does, plus.
