Predicted Beaver Dam Building Capacity in the Minneapolis-St. Paul Metro Area

The Beaver Restoration Assessment Tool (BRAT) (MacFarlane et al., 2015) is a predictive model that integrates hydrology, topography, vegetation, and land use data to predict existing and historical beaver dam building capacity within a watershed. The model was run on the HUC8 Mississippi River Twin Cities Watershed (07010206) in March 2025. The output displayed is a shapefile of the Conservation Restoration Model, which includes existing and historical dam building capacity as well as restoration opportunities.

海狸恢复评估工具（Beaver Restoration Assessment Tool, BRAT）由MacFarlane等（2015）提出，是一款整合水文、地形、植被与土地利用数据的预测模型，可用于预测流域内现存及历史时期的海狸筑坝能力。该模型于2025年3月在HUC8级密西西比河双子城流域（07010206）中运行。所展示的输出结果为保护恢复模型（Conservation Restoration Model）的形状文件（shapefile），涵盖现存与历史筑坝能力及恢复潜力。
