Land use change effect on habitat loss rate of dipterocarp species in Sabah using species distribution modelling

Forest cover in Malaysia comprises of 60 % of its land area or 19.5 million hectares while 4.45 million hectares of Sabah is currently under forest cover. Extent of forest cover in Borneo is rapidly declined that also affecting the habitat available for many flora and fauna. Furthermore, the forest...

The percentage of habitat loss for Anisoptera marginata, Anisoptera reticulata and Dipterocarpus acutangulus for year 2008 are 73.1%, 56.2%, and 57.6% respectively.
