Comparative study of mangrove composition and diversity in Kudat and Pitas, Sabah

The objectives of this study were to compare the floral diversity, species composition of mangrove plants species and compare the natural regeneration between disturbed and undisturbed mangrove forest in Kudat and Pitas, Sabah. The most common mangrove species identified were Rhizophora apiculata, R...
