Responsible Collecting Practices
The Conservancy emphasizes the importance of environmental stewardship to protect the site for future generations. To minimize the impact on the landscape, visitors are asked to adhere to specific guidelines.
Collection should be limited strictly to the stream bed. Digging into the banks is prohibited, as this activity hastens erosion and damages the geological integrity of the area. Furthermore, visitors are encouraged to collect conservatively and donate any unusual or rare finds to the Nature Center for study and display.
