We performed statistical analysis for birds fish. The analysis aimed to reveal how distribution of birds relates to stand size and stand structure, and how distribution, food consumption, and growth of fish relate to the presence of riparian woods. By piling up distribution of birds on map of environmental compartments of riparian woods, the analysis for birds showed the stand size necessary to the assure inhabiting of riparian-dependent bird species and the stand structure appropriate for the propagation of birds. The analysis for fish proved that riparian woods are beneficial in point of population density and growth of masu salmon (Oncorhynchus masou).}, pages = {327--332}, title = {豊平川における河畔林伐採と生態環境との関係}, volume = {10}, year = {2004}, yomi = {ミタ, ケンヤ and キザワ, カズフミ and ヤベ, ヒロキ and ナカツガワ, マコト} }
