Abstract:

A total of 44 families, 89 genera and 103 beach forest species were identified. The most numbered family is Euphorbiaceae (9), Leguminosae (8) species, Compositae and Poaceae (7) and Rubiaceae (6), Malvaceae (5) Araceae, Convolvulaceae (4), while the rest of the genera have three to fewer species. Among the sites, Habag beach forest is the most diverse with 38 families, 80 genera, 95 species followed by Pagbabangnan beach forest with 25 families, 32 genera and 32 species and Casuguran beach forest with 21 families, 30 genera, 33 species. The findings of the study would be a great help to at least fill the gap on the scarcity of data on the beach flora species on the Philippine Island. The forest of Homonhon Island is affected by mining activities, with the depressing threats of extinction at hand. It is hoped that the findings of this study will encourage more researchers to perform a floristic survey of the Philippine beach forest to catalogue the species before they become prey to extinction.
