Help to preserve this haven for wildlife and people by following these rules:

• Please stay on marked trails or roads at all times.

• Do not collect or disturb the wildlife, including flowers or other plant materials, animals, birds, insects, rocks or any element within the Sanctuary. Harvesting of berries is allowed along Riparian View.

• Smoking, fires, and camping are not permitted. Please carry all trash out with you, including food scaps.

• Please do not feed the wildlife.

• Boating, swimming and wading are prohibited.

• Dogs and other pets - leashed or unleashed - are not permitted on the property.

• Hunting, fishing, trapping, and firearms are prohibited.

• Please obey all trail signs.
