Abstract

The objectives of study were to compare tree and seedling species and were to know difference of microclimate between 60 year-Mahogany plantation(Swietenia macropylla King) after planting and secondary forest regenerated naturally in Mt. Makiling, Philippines. The study sites are located in Mt. Makling Forest Reserve (MFR) at 400m above sea level, Philippines. Total number of tree species with DBH above 5cm was 43 and 16 in secondary forest and Mahogany plantation, respectively. Stand density in secondary forest and Mahoany planation were 842 tress/ha and 617 trees/ha. Total basal area of Mahogany plantation was higher than that of secondary forest. Celtis luzonica showed the highest IV followed by D. paniculatus in secondary forest. Shannon's diversity index and Simpson's index in secondary forest site were higher than in Mahogany plantation site significantly. Evenness of secondary forest site showed significantly higher than that of Mahogany plantation. Distribution of seedling height and root collar diameter showed reverse J pattern in both areas. Also, distribution of tree height and DBH showed reversed-J-shape pattern in secondary forest however, reversed-J-shape pattern of tree height and tree DBH were repeated at 30m and 50cm in Mahogany plantation, respectively. Mahogany plantation showed similar air temperature with secondary forest however, soil temperature was significantly higher in mahogany plantation than in secondary forest. Secondary forest showed significantly higher relative humidity than that of mahogany plantation. Variation of air temperature and relative humidity were larger in mahogany plantation than in secondary forest. Highest air temperature, relative humidity and soil temperature were on April during dry season. These results suggest that dfferences in restoration ways cause various responses in species diversity and microclimate. © 2006 Taylor & Francis Group, LLC.
