Geomorphic Assessment and Opportunities for Improving stream and riparian condition
Near Saratoga, Wyoming
This project represents the first phase work with Six Forks Ranch, located in the Sierra Madre mountains of southern Wyoming. Six Forks ranch is dedicated to conserving upland and riparian areas through a diverse set of restoration approaches. In 2021 we worked with Six Forks Ranch on an assessment of all perennial streams on the ranch, by using an extensive analysis of historic aerial imagery and a full ground survey, in which we walked every stream mile, making observations of current and recent beaver dam activity, and geomorphic and riparian characteristics. We used the combination of field observations and historic imagery analysis to develop a better understanding of the range of conditions found on Six Forks Ranch, and develop a plan for future restoration.
Because many streams on Six Forks Ranch are currently in good condition, and characterized by a range of recent and historic beaver dam activity, they are well suited to Low-Tech Process-Based Restoration (LTPBR) approaches, which can encourage specific geomorphic and hydrologic processes without negatively impacting the current conditions.
In 2022, we will be working with Six Forks Ranch to develop and implement a restoration on streams throughout the ranch.
Historic aerial imagery of the site shows beaver dam dynamics over the years in the different creeks. These figures help to contextualize current beaver dam activity and helps inform future restoration opportunities. Ponds are shown in blue and were delineated manually in QGIS.
