Abstract or Summary
  • Deforestation and forest fragmentation are the primary threats to the habitat of endangered lion-tailed macaques, Macaca silenus, in Karnataka, India. Landsat satellite images of northwest Karnataka, India, from 1977 and 1990 were analyzed. Two study sites, measuring 16.35 x 19.14 km (31,213 ha) and 14.34 x 21.44 km (30,561 ha), respectively, were selected for analysis. Based on a group home range estimate of 131 ha, contiguous habitat fragments large enough to support two or more groups of lion-tails remained available in the study area in 1990. A single contiguous patch of 14,718 ha in Site 1 and two contiguous patches in Site 2, 4,276 ha and 9,097 ha respectively, were available for reintroduction of captive lion-tailed macaque populations. Loss of habitat has primarily been occurring in and around previously disturbed regions. Although the study identified potential unfragmented sites, there is still a need for ground-truthing.
