Characteristics of bird communities between slope and valley in natural deciduous forest, South Korea
- 33 Downloads
Bird communities were surveyed in natural deciduous forest of both slope area and valley area at Mt. Gyebangsan (37°40′ 30″ N, 128°30′1″ E), Gangwon Province, South Korea in winter, spring, summer and autumn from September 2000 to November 2001. The investigating results showed that there existed differences in the bird species composition, richness, bird species diversity, guild structure between slope area and valley aree, and the vertical forest structure, especially coverage of understory, and diameter at breast height (DBH) distribution also had significant difference between the two study areas. The differences in habitat structure between the areas are very likely to have influences on how birds used the available habitat.
