Assessment of landscape patterns for modeling habitat suitability for lions and prey species in Gir Protected Area, Gujarat.

Abstract

Conservation of ‘source’ alone may not be a sufficient strategy to ensure long term persistence of lions; rather it is enhanced by maintaining connectivity among different populations so as to permit lion movement across human-dominated areas. However, the traditional land-use patterns within Gir landscape is changing at an alarming rate mainly as a result of agricultural expansion, urbanization and industrialization. In this scenario, I attempt to (1) Examine the distribution of suitable lion habitat in Saurashtra, especially in areas outside of protected area to assess the potential of the landscape for supporting an increasing lion population, (2) Identify functional corridors joining Gir and Girnar protected area with suggested management interventions, necessary for safeguarding the corridor, (3) Evaluate the current landscape architecture of Gir PA and its surroundings (4) Assess the rate of change in land use and vegetation patterns within Gir PA, (5) Develop habitat suitability models at different spatial scales for lions and its principal prey species.
