RELATIONSHIPS BETWEEN AVIAN DIVERSITY AND AGRICULTURAL LANDSCAPE HETEROGENEITY

ABSTRACT Studies on birds and their habitats are usually conducted in natural areas (protected areas, forests, wetlands, etc.). In this study, the relationship between agricultural landscape diversity species of was investigated an zone surrounded by forested areas. Observations were carried out 60 sample grid squares. Presence/absence data for cultivated plants at each site recorded. The Shannon-Wiener index bird metrics used site. A multiple linear regression analysis performed to explain correlation diversity. According results, area-weighted mean shape (AWMSI) number patches (NP) found be particularly effective predicting (R2 = 0.66). addition, as patch ratio increased a area, (R 0.83) expanded. It can concluded that zones consisting small, different rich Bird is lessened with uniform or similar structures large patches. If NP area high, but not distributed mosaic pattern, then considered weak. Despite increasing types, declines if there intense human activity area.
