protected Area cannot completely sustain biodiversity, thus understanding the role of human-disturbed areas in conserving the worlds diversity in critical. Despite intensive deforestation, Southeast Asia is underrepresented in studies investigating faunal communities in human-modifiled landscapes. This project assessed the herpetofaunal community in dry dipterocarp forest, secondary disturbed forest, and eucalyptus plantations in the Sakaerat Biosphere Reserve. In May, June, and September of 2015 , we surveyed using 11 passive trapping arrays. Each array consisted of 12 double funnel traps and three 40 L pitfall traps. We assessed habitat characteristics at each site collected from six 1m x 1m quartats at each site. To collect landscape variables such as elecation and patch size, we used ArcGIS mapping software. Analysis of the habitat cahracters using multiple correspondence analysis (MCA), did not reveal any clustering of the sites.
The results showed 861 individuals were captured representing 40 species. The eucalyptus plantations (361 individuals, 37 species) and highly disturbed forest sites (373 individuals, 29 species) hoted higher herpetofauna abundance and richness than protected areas of dry dipterocarp forest (127 individuals, 29 species)
Both the PLE and HDF (224 and 275 individuals respectively) had higher amphibian abundance than the DDF (57 individuals) Reptiles in contrast showed the highest anundance in the PLE sites compared to the other two forest types, with 100 captures compared to 54 in the DDF and 57 in the HDF. Based on sample based rarefaction herpetofaunal species richness did not vary between forest types, but did vary significantly between the DDF compared HDF and PLE sites when comparing amphibian species. We did not find any significant differences in community structure among forest types based on non-metric multidimentional scaling and PERMANOVA
