Distribution and Diversity of Mangrove in the Philippines
Transcript of Distribution and Diversity of Mangrove in the Philippines
(Seed plants) Division Magnoliophyta
(Flowering plants) Class Magnoliopsida Subclass Rosidae Order Rhizophorales Family Rhizophoraceae Order Myrtales Family Lythraceae Family Melastomataceae Family Myrtaceae Class Rosospsida Order Lamiales Family Lamiaceae Family Verbenaceae To be able to present the species in different selected areas To delineate the mangrove degradation in the Philippines To enumerate several uses and/or advantages of mangrove forests in the Philippines Worldwide distribution of mangroves (Forestry Dept., FAO, United Nations, 1994). Of the total mangrove coverage, 41.4% exist in South and Southeast Asia Traditionally, mangroves are used for the production of firewood, charcoal, alcohol, medicines and thatching used for construction. It provide biological protection from coastal erosion. It provides a ground for nurseries and feeding ground for marine species Spatial distribution of mangrove forests of the Philippines for 2000. Mangrove areal extent by province. Geographical Distribution of Mangrove in Aurora Avicennia lanata Avicennia marina Avicennia officinalis Bruguiera gymnorrhiza Bruguiera parviflora Bruguiera sexangula Ceriops tagal Kandelia candel Lumnitzera littorea Nypa fruticans Rhizopora apiculata Rhizopora mucronata Diversity of mangrove species in Danjugan Island, Cauayan,Negros Occidental, Philippines Schematic outline map of Danjugan Island with location of lagoon areas where mangrove stands were identified. Total abundance of true mangrove species in each lagoon on Danjugan Island Lumnitzera littorea Avicennia marina Rhizopora stylosa Sonneratia alba Sonneratia caseolaris Exocoercia agallocha Xylocarpus granatum Xylocarpus moluccensis Aegicera sp. Nypa fruticans Bruguiera cylindrical Bruguiera gymnorrhiza Ceriops decandra Rhizophora apiculata Rhizopora mucronata Sonneratia alba Sonneratia caseolaris Another is the need of constructing residential houses for landless residents, thus clearing the forests. Delineation Conservation Requirements for fish pond lease application had been tightened all-throughout the country. During the early 1900s, a wide-spread ban of cutting trees are implemented Legal permits to clear forest was also made difficult to obtain Switching to alternative sources of fuels and income CONCLUSION The diversity of mangroves is relatively high because of its geographical location wherein environments are subtropical or tropical where mangroves can thrive in.
