Chaiwat Moocharoen
This study focused on the effect of land use changes and land cover on bird diversity in the Chuen Watershed, Changwat KhonKhaen, between February 1995 and February 1996. The objectives were to investigate the species and number of birds found in the areas where land use and land cover were changed and to examine if there was any correlation between bird diversity and the habitat type. From surveys in eight different habitats, 14 orders, 43 families, 96 genera and 143 species were found. Most of these species were residents. If classified by habitats, 79 species were in natural forests; 32 species in Teak plantations; 32 species in Leucaena plantations; 54 species in rice fields and wetlands; 28 species in open areas; 29 species in mixed gardening areas; 14 species in banana growing areas ; and 14 species in settled areas. It was found that bird species and habitat type were correlated. Moreover, birds adapt themselves to different environmental. Factors affecting the number of bird species included the type of food, eating behavior and habitat. As for the effect on bird diversity, the results revealed that 60, 52, and 31 species were in the highly, slightly and no affected groups respectively. The results of this study can be used for preventative and solution measures against the effects on bird species.
