Tips for a Successful Visit

Plan Ahead
Check the weather, watch for hazards, and follow all the rules of the Preserve. Look over our trail map and print or download a copy to bring with you. Remember proper clothing and shoes, sunscreen, hats, first aid supplies, and plenty of drinking water.

Stick To Trails
Stay on the trail system. Short-cutting trails causes the soil to wear away or to be packed, which eventually kills trees and other vegetation. Trampled wildflowers and vegetation take years to recover. Contact us to report any trail issues, such as fallen trees or other hazards. Please be specific about the problem's location by referencing the trail name and nearest interpretive sign.

Leave What You Find
When visiting any outdoor area, try to leave it the same as you find it. The less impact we each make, the longer we will enjoy what we have. Even picking flowers denies others the opportunity to see them and reduces seeds, which means fewer plants next year. Graffiti and vandalism have no place anywhere, and they spoil the experience for others. We encourage nature journaling and photography to remember unique observations and special moments.

Respect Other Visitors
Expect to meet other visitors. Be courteous and make room for others on the trails. Control your speed when running or jogging. Pass with care and let others know before you pass. Don’t disturb other visitors by making noise or playing loud music. Respect “Private Property - Residents Only” signs. If property boundaries are unclear, do not enter the area.

Trash Your Trash
There are no trash receptacles in the Preserve. Make sure all trash is put in a bag and carried out with you. Trash is unsightly and ruins the outdoor experience for others. Your trash can kill wildlife. Even organic materials such as orange peels, apple cores, and food scraps take years to break down and may attract unwanted pests.

Group Events

We welcome naturalist events in the preserve. Birding clubs, art classes, wildflower groups, student field trips, etc. are welcome! Please contact us so we know to expect you and follow up afterwards with pictures, counts, and number of participants.
