The vegetation was chiefly characterized by the Sphagnum-sedge community. We recorded 242 species of vascular plants and 4 sphagnum species in this area. Population of some Liliaceae and Orchidaceae species have decreased over the past 12 years. It may be caused by drought associated with human impacts. Additionally, conservation of peripheral environments (e.g. secondary beech forests) and improvement of the trail are necessary to preserve drainage areas and streams that provide the mire with water., Article, 信州大学教育学部附属志賀自然教育研究施設研究業績 (40): 15-27(2003)}, pages = {15--27}, title = {北志賀高原三ヶ月池アワラ湿原の植生と植物相}, volume = {40}, year = {2003} }
