17. Population estimation of grey Francolin (Francolinus Pondicerianus) in salt range, Punjab, Pakistan
Main Article Content
Abstract
The genus Francolinus belongs to Order Galliformes and Family Phasianidae and is diverse genus of game birds. Grey francolin (Francolinus pondicerianus) belongs to this genus and is a medium size game bird, serving as an operator of biological control. Population of grey francolin has declined over the time mainly due to excessive hunting and habitat destruction. Research studies have not been carried out on Grey francolin in the Salt Range and data on their biological and ecological aspects is lacking. The current study was conducted in two protected areas i.e. Chumbi Surla Wildlife Sanctuary (CSWS) and Diljabba Domeli Game Resrve (DDGR) to generate information about population density and distribution pattern of Grey francolin in the Salt Range. For population estimation, 40 transects were laid in the both areas and Grey francolin population were recorded both by direct sighting and calls and data was analyzes by DISTANCE Software 6.0. Significant difference was recorded in population densities among different sites both by sighting and calls method. In CSWS, population density by sighting was the highest at Open land habitat (3.23 individual ha-1) while lowest at cultivated habitat (1.58 individual ha-1) and by calls was the highest at (2.87 individual ha-1) from natural forest habitat, while lowest at (1.59 individual ha-1) from cultivated habitat. In DDGR population density by sighting was highest from wetland (2.47 individual ha-1) and lowest at (2.09 individual ha-1) from natural forest habitat, by calls highest from open land habitat (2.45 individual ha-1) and lowest from wetland habitat (1.10 individual ha-1). This study would provide essential scientific base about population and distribution patterns of grey francolin in the study area that is required for the conservation of grey francolin, ultimately helping in sustaining the population of this important game bird in the Salt Range.
