Tree Recruitment from On-site Versus Off-site Propagule Sources During Tropical Forest Succession

摘要: The management of successional forests has become an increasingly important tool for tropical forest restoration on disturbed lands. Successful depends understanding factors governing tree recruitment during succession. Recruits can be on-site propagules surviving disturbance (e.g. saplings) or seeds arriving after disturbance. Among sites, the importance seed arrival from off-site should increase as availability declines. This study examines how seemed to influence natural regrowth logged plantations in Uganda. Specifically, effect mammals (determined directly) and birds inferentially) was estimated two with high three low quantities saplings logging. In both plantation types, first-year originate (seed bank sprouts damaged trees) sources (seed-dispersing birds). Recruitment declined 2–3 years logging all despite densities seed-dispersing birds. generally greater initial propagules, by 4–6 structure similar between types. dominated bird-dispersed species, rather than mammal- wind-dispersed species. Taken together, these results illustrate that areas propagule have much potential regrowth.
