Bird communities and seedling recruitment in restoring seasonally dry forest using the framework species method in Northern Thailand

摘要: This study examined the effects of framework trees, planted in 1998, and bird community on natural recruitment tree seedling species a forest restoration experiment designed to test method established by Chiang Mai University’s Forest Restoration Research Unit (FORRU-CMU). Tree seedlings establishing beneath five species: Erythrina subumbrans (Hassk.) Merr., Hovenia dulcis Thunb., Melia toosendan Sieb. & Zucc., Prunus cerasoides D.Don Spondias axillaries Roxb., were surveyed. Five trees each selected 8-year-old trial plots. Birds visiting observed determine possible seed dispersal activities. Thirty-six found which 11 wind-dispersed 25 animal-dispersed. The population density animal-dispersed was higher than all trees. sample plots P. supported highest seedlings. Forty-nine recorded between July 2006 June 2007. Non-frugivorous birds more frequently frugivorous birds. different among tree. Bigger attracted high number providing food resources, roosting nesting sites may increase deposition smaller with fewer attractants.
