Change of bird communities at the larch plantation forests and deciduous forests in Jungwangsan, Korea
To coping with international convention and treaty relating with biological diversity, and to enhance the public awareness on the effect of forest practice on biodiversity and sustainable forest management in Korea, we evaluated the thinning effect on bird communities at Larch plantation forests (LF, 25.0% thinning at 9ha in size, a.s.l. 1,200m) and deciduous forests (DF, 55.3% thinning at 15.8ha in size, a.s.l. 600m) after two years from 2013 to 2015. Bird communities were surveyed by the combination of point counts (9 points) and line transect methods during breeding and non-breeding seasons with the sounds and observation by binocular and camera. We analyzed the composition of bird communities with nesting and foraging guild. After thinning practice in early spring of 2013, total 15 and 21 birds were recorded in 2013, forty and thirty-one species of birds in 2014, and sixty and forty species of birds in 2015 at the DF and LF, respectively. Data showed that one year took to recover the number of species after thinning at DF sites, and bush-nesting birds such as Winter Wren and Hazel Grouse were increased after thinning at LF sites. At a large forests area in Mt.Jungwangsan, forest practice like a 25.0% thinning at LF and 55.3% thinning at DF sites could not affect the bird community and increase the habitat diversity to attract the forests birds prefer bush and open space in forests areas. These results imply that spatial and temporal arrangement in a landscape approach could be fully considered to maintain and enhance biodiversity in forests.
