Abstract

Reptile is a group of animal consists of testudines, crocodiles, lizards and snakes. Most reptiles are capable to occupy wide range of habitats with different environmental conditions. One of the preferred habitats for reptiles is river. Boyong-Code River is one of the rivers which flow across the Province of Daerah Istimewa Yogyakarta (DIY). Research on the diversity of lizards and snakes in the Boyong-Code River has been done in 2012. This research is aimed to acquire new data on the diversity of herpetofauna in the Boyong-Code River and compare it with 2012 data research. The comparison purpose is to monitor the species diversity dynamics after 5 years. The data of herpetofauna diversity were acquired using a combination of several methods, i.e., VES (Visual Encounter Survey), riverbank cruising and transect. Sampling area in 2012 and 2017 were divided three four locations, i.e., upstream, midstream, and downstream. Species diversity of lizards and snakes in the Boyong-Code River in 2017 is consisted of 8 species of lizards (lacertilians: squamates: reptiles) and 4 species of snakes (serpents: squamates: reptiles). Species diversity dynamics is equal for lizards in 2012 and 2017- meanwhile there were more species of snakes in 2012 compare to the 2017.
