- 8. Beaver ponds trap sediment Beaver pond on Basin Creek trapping sediment from natural sediment source and grazing-related inputs. Ruined beaver pond on Indian Creek had trapped about 3 feet of sediment over a wide area.
- 17. More considerations… Fish habitat and beaver habitat are both much reduced - not much room for natural cycle of beaver ponds or cyclic local impacts on fish populations. Newly-formed meadows and silted-in dams are very susceptible to severe erosion due to trampling, and prone to incisement. Grazing management must be part of any plan for beaver reintroduction. Increasing riparian vegetation in areas where it is lacking should be part of a long-term strategy for beaver reintroduction and watershed restoration.
