This study was conducted to investigate the user's effects on the avifauna in Chiak Mountain National Park. The survey was carried over 5 districts which were 3 main trail (valley) by line transect method from May to October 1988. The observed birds were 44 species and 613 individuals. these consist of 22 species for residents, 13 species for summer visitor, 5 species for winter visitor and 4 species for passage migrant. The average density of birds was 2.96 ea/ha, and main dominant species were Panus minar, Paradoxomis webbiana fulvicanda, Panus palustris hellmayri and Parus ater amurensis in order. The observed frequency of wild-birds was 6.77 times/km in average. No. of species, species diversities and observed frequency were lower in main trail of high user's density than sub trail and closed trail, especially in summer. But similarity indices were affected by inhabitation environments than user's density. Therefore, from now, in Chiak Mountain National Park management, the enjoyment oriented activities will be regulated and the control of trail use on main trail are necessary during breeding periods for wild birds protection. |
