| Tiger went of the hill - A case study from Parsa Wildlife Reserve in the Terai Arc Landscape, Nepal | |
| 2007 Full Book | |
Parsa Wildlife Reserve is the only protected area geographically located in extreme dry zone of Terai Arc Landscape. The objective of the project focused on assessing abundance of tigers and prey base in Parsa Wildlife Reserve. The encounter rate survey of tiger signs was used for the purpose. Camera trap survey and pellet count methods have been used to assess underlying objectives. Pugmark assessment have been undertaken to further quantify individual tiger presence in the reserve. Seven minimum populations of tigers have been identified in core area of the reserve. Fortytwo routes have been identified for carrying out encounter rate survey of tiger signs. Only 2.7 per cent of these sampled segments within identified routes had tiger tracks present in them. Detection probability was found to be only 16 per cent. The abundance of wild ungulates provided by density of dung was found to be 1.06 ñ 1.43 pellet groups per 10m2. Spotted deer abundance was high in comparison to other tiger prey species. However, biomass of Gaur and Sambar was found to be higher (expressed in terms of Sambar Unit). Rich prey abundance confirms good breeding population of tigers in the reserve. Moreover, prey abundance was found to be increasing against 2000 baseline (Shrestha 2004). Grazing pressure was found to be high in the reserve. Distribution of livestock had negative relationship with presence of wild ungulate in the reserve. Parsa Wildlife Reserve in conjunction with Chitwan National Park is the only source population of tiger for its migration into eastern part which provided the continuous connectivity from Parsa Wildlife Reserve. Given the adequate protection and presence of rich prey abundance, tiger can climb up the hill into intact tiger habitat in the region. |
