<b>Predictive Equations for Determining Crown Area and Crown Volume of Recovering and Intact Willows Based upon Height at Yellowstone National Park</b>

We developed equations to determine crown area and crown volume of willows based upon height at Yellowstone National Park. These variables best describe structural diversity and habitat values of these important riparian communities in the montane ecosystems of the western USA. Here. we provide the raw data from which we developed the equations.本研究基于黄石国家公园（Yellowstone National Park）内的柳树株高，构建了用于测算柳树冠幅面积与冠幅体积的回归方程。上述冠幅相关变量可最优表征美国西部山地生态系统中这类重要河岸群落的结构多样性与栖息地价值。本研究在此提供构建上述方程所依托的原始数据集。
