광릉숲 일대 관람객이 조류분포에 미치는 영향 연구 = Study on Effects of Disturbances by Visitors on Avian Distribution in Gwangneung Forest

국문 초록 (Abstract)

본 연구는 2005년 2월부터 2006년 10월까지 광릉숲 일대의 관람객이 조류분포에 미치는 영향을 분석하기 위하여 수행되었다. 10년간 광릉숲 일대를 방문한 관람객들은 한해 평균 402,484±284,023명이었다. 이들에 의한 소음도는 오전에 개방지역에서 평균 61.3±4.3dB, 비개방지역에서 평균 49.3±4.5dB이었으며, 오후에는 개방지역에서 평균 80.6±5.1dB, 비개방지역에서 평균 53.6±1.0dB로 나타나 오전과 오후 모두 개방지역에서 높았다(t=7.50, P＜0.001, t=20.21, P＜0.001). 관찰된 조류는 총 76종이었으며 비개방지역과 개방지역에서 각각 17종(16.8%) 및 8종 (7.9%)이 확인되었다. 단위면적당 관찰된 종수는 비개방지역(평균 19.51±1.0종/ha)이 개방지역(평균 15.69±0.8종/ha)보다 더 많았다(t=2.95, P＜0.01). 밀도(개체수) 역시 비개방지역(평균 126.39±11.2개체/ha)이 개방지역(평균 83.67±6.1개체/ha) 보다 더 많았다(t=3.33, P＜0.01). 인공소상에서의 번식률은 비개방지역(14.0%)이 개방지역(2.0%)보다 높았다(χ²=4.180, df=1, p＜0.05).

This study conducted from February 2005 to October 2006 to investigate effects of disturbances by visitors on bird distribution in Gwangneung Forest. During 10 years, the average number of visitors in Gwangneung forest were 402,484±284,023/year. The noise levels of opened area were higher than restricted area in all the time (t=7.50, P＜0.001, t=20.21, P＜0.001). In the morning, the average noise level of opened area was 61.3±4.3dB and the restricted area was 49.3±4.5dB. In the afternoon, the average noise level of open area was 80.6±re1dB and the restricted area was 53.6±1.0dB. The number of birds observed in common area of restricted area and open area was total 76 species. 17 species and 8 species were observed in only restricted and opened area, respectively. The average number of birds observed in restricted area (19.51±1.0/ha) was higher than open area (15.69±0.8/ha) (t=2.95, P＜0.01). The average number of birds observed in restricted area (126.39±11.2/ha) were higher than open area (83.67±6.1/ha) (t=3.33, P＜0.01). In the breeding success, nest boxes in restricted area (14.0%) was higher than open area (2.0%) (χ²=4.180, df=1, p＜0.05).
