ABSTRACT Gutierrez, Suzette G. BS Biology (Systematics). University of the Philippines, 1..os Bafios, College of Arts and Sciences. October 1997, Taxonomic Survey of Vascular Plants and Vegetation Analysis of the Southeastern Slope of Mt. Banahaw, Quezon Province. Undergraduate thesis.

Five plots (plot 1, 1600 masl-, plot 2, 1400 masl: plot 3, 1200 mast; plot 4, 1000 mast; plot 5, 800 masl) with intervals of 200 m in altitude were established along a transect line laid out on the southeastern slope of Mt. Banahaw. Each plot had a diameter of 40 m. The method of vegetation study used was the line Transect-Circular Plot Method. Vascular plants encountered in each plot were listed along with the number of times they occurred per quadrant and fertile samples were collected when available. Diameter-at-breast height (dbh) of trees was measured and plants having a dbh of not less than 10 cm were listed as trees. The relative density and relative frequency were determined for all plants present in each plot while the relative density, relative dominance and importance value were computed for trees. The important families obtained for each plot were Theaceae (plot 1 and 2), Clethraceae (plot 3), Meliaceae (plot 4) and Moraceae (plot 5), represented by Etirya niiida, Clethra 1wwijblia, Aglaia aherniana and Ficus benjerniimi, respectively Plot 3 (1200 mast) had the most number of genera and species while plot 5 (800 masl) had the most number of families. The average basal area of trees generally tends to decrease with increasing altitude (plot 5 500.44 cni!, plot 4: 312.71 cm3,.. plot 3: 174.37 plot 2 146.45 cm`; plot 1: 216.71 cm3 Adjacent plots were found to contain more common
