| dc.description.abstract | This study was conducted to assess the distribution and diversity of trees in Mount 387, Carrangalan, Nueva Ecija. A total of 20 species representing 13 families were recorded. Quadrat method was used to survey the trees, native trees dominated the area with 10 different species, these were C. kuzonicum, S. apiculata, P. speciosa, P. malabaricum, C. dichotoma, P. indicus, V. parviflora, S. cumuni, and P. odoratissimus. Six species were classified as introduced, whichwere M. indica, C. indicum, G. arborea, P. serratifolia, X. lanceatum and O. frutescens. Followed by 4 endemic species, namely, D. purpurea, A. treculianus, P. kesiya and T. philippinensis. Out of the 20 species recorded, 2 species were categorized as vulnerable, 2 endangered and 1 species listed as threatened based on the latest IUCN Red list of Threatened species. T. philippinensis recorded the highest computed population indices values in terms of frequency (0.9%), Relative frequency (20.5%), Density (0.003%) Relative density (3%), Dominance (0.0116%) and Relative dominance (0.42%). The calculated diversity index of Mt. 387 was 2.28 H' which was low density. Moreover, Jaccard's similarity was used to see the similarities between quadrat. Computed highest similarity index was noted at Quadrat 2 and 4 as well as quadrat 7 and 8. Wherein, in quadrat 2 and 4 are near the water source which helps the trees to grow. Meanwhile, sufficient supply of light may explain the similarity between in Quadrat 7 and 8. Quadrat 3 did not show any similarities. This is because most of the trees were fallen down due to natural calamities. Local people utilizes some of the trees as medicine, timber, food, food addictive, and more. The finding of this study imply that conservation efforts shoul be implemented since the area is dominated with native species and endemic species. | |
