Ecological Survey on the Mikado Pheasant and Swinhoe’s Pheasant in Yushan National Park
中文摘要
本研究於74年11月至75年12月之間進行，主要在調查玉山國家公園範圍內帝雉與藍腹鷴之分布、數量、生態需求及基本行為特色。14個月中研究人員共至現場調查22次，調查方式分廣面調查及特定地區深入研究二部份。特定地區為八通關古道及郡大林道觀高工作站至60公里路段。
在玉山國家公園範圍內，帝雉分布於海拔1900~3900公尺之間，較喜歡在原始混合林中山坡坡度較陡的地區活動（坡度30~60度之間），但在其他環境中也會出現。根據推算，區內帝雉數量應在5600與10,000之間。藍腹鷴生存在海拔2000公尺以下的闊葉林中，其出現環境大多坡度較緩（30~40度之間）。根據推算，區內藍腹鷴數量應在3600與6500隻之間。根據研究結果最重要的是棲地保育，尤其藍腹鷴的棲地為低海拔之原始闊葉林，面積有限，又易受干擾。
英文摘要
From November 1985 to December 1986, a study was conducted on the distribution, population, ecological needs, and basic behavioral characteristics of the Mikado pheasant (Syrmaticus mikado) and Swinhoe’s pheasant (Lophura swinhoii) in Yushan National Park. Over a 14-month period, researchers conducted 22 surveys in the study area. Methods used include a broad survey and in-depth surveys designated locations: the Batongguan Historical Trail and the section between the 60K and the Guangao work station on the Juinda Forest Road. The Mikado pheasant is found at an altitude of 1900-3900 m in Yushan National Park, and prefers the steep slopes (30-60 degrees) of pristine mixed forests, but it can also be found in other environments. The estimated population of the Mikado pheasant in the area is between 5,600 and 10,000. The Swinhoe’s pheasant is found in broad-leaf forests at altitudes below 2,000 meters. They are mostly found in areas on gentler slopes (30-40 degrees). The estimated population of the Swinhoe’s pheasant was between 3,600 and 6,500. This study indicates that habitat conservation is the most important factor for the survival of the pheasants, especially the pristine broad-leaf forests at low altitudes favored by the Swinhoe’s pheasant, which are limited in size and susceptible to disturbance.
