Abundance and biomass of Thalassia hemprichii (Ehrenberg) Ascherson in the seagrass bed of Kauswagan, Lanao del Norte, Mindanao, Philippines

The abundance and biomass of Thalassia hemprichii (Ehrenberg) Ascherson was determined in seven coastal barangays of Kauswagan, Lanao del Norte, namely: Poblacion, Bagumbayan, Tacub, Libertad, Tugar, Kawit Oriental and Kawit Occidental, over a two month period December 2013 - January 2014. Shoot density, above and belowground biomass and ratio of above to belowground biomass were highest in Barangay Tacub and the values were comparable to other studies. It appears, therefore, that this intertidal seagrass contributes significantly to coastal productivity of the shallow coastal marine ecosystem in Kauswagan, Lanao del Norte.
