| Abstract: | The aim of this study is to investigate the diversity, relative abundance
and habitat association of the avian species in Chebera Churchura
Nation Park (CCNP). The study was carried out using the method of
Timed-Species-Count technique (TSC) during August 2005-April 2006,
covering both dry and wet seasons. The study area was stratified
based on major vegetation types. Each vegetation type was used as a
sampling site. Small crater lakes and farmland areas were also
considered as sampling sites, to asses the species inhabiting water
bodies and farmland areas. A total of 137 bird species was observed.
The mean number of species per count was significantly correlated
with the total number of species in each vegetation type both during
the wet and dry seasons (r=0.84 and 0.78, respectively). Unusual
relationship was observed between total vegetation cover and number
of species in the montane forest (12 species and 15 species during the
wet and dry seasons, respectively). The relative abundance of each
species in different vegetation types of both seasons showed variation.
During the wet season the relative abundance or the mean score value
ranged between 0.2 and 5.75 and during the dry season it varied
between 0.2 and 5.5. Shifting cultivation was considered to be the
most significant threat of wildlife in the area. |
