Fig. 1.
Location map showing five selected field sites for avifauna data collection in Gujranwala area. The landfill site is a large depression in the ground and is being filled by solid urban waste. Locations marked ‘X’ shows sites points where field observations of avian species were taken.

Maps showing spatial distribution of selected wildlife avifauna based on field data (birds per 10 min) from the agriculture, landfill, urban, forest and lake sites. Abundance (Figure-g is the total number of birds) and diversity (Figure-h is the number of species) were also determined in this study.

Graph showing baseline situation of 56 wildlife avifauna species of the Gujranwala area with error bars from the four selected sites (~99% land use) as the number of birds observed per 10 min. The Landfill site histograms show the number of birds in contrast to the local baseline situation.
