The main goal of this project was to analyze all the perennial rivers and streams within the Yakama Nation Reservation and generate spatially explicit outputs to help Yakama Nation biologists effectively identify where nuisance beaver can be relocated, where ‘Living with Beaver’ strategies may be needed and where beaver can be used for watershed restoration efforts. Further information concerning the scope of this project can be found on the BRAT website in the Yakama Nation Reservation BRAT folder.
Customizations for this project
Over the course of this project we developed a new methodology for addressing multi-threaded streams. Specifically, the Yakama River has side channels where beaver build dams and the BRAT model now effectively captures the dam building capacity of side channels. Further editing of the vegetation codes based on field observations were accounted for. An in depth perennial network was created with a combination of f codes and imagery verification using ArcGIS imagery.
Yakama Nation BRAT Deliverable Data Products include:
- KMZ files of the four primary BRAT outputs (existing dam capacity, historic dam capacity, human-beaver potential conflict and beaver conservation and restoration zones)*
- Shapefiles and Geodatabases for the four primary outputs and standard inputs*
- Posting of existing and historic beaver dam capacity output layers to public website*
- Inventory of existing beaver dams as KMZ*
- Atlas of BRAT outputs here
