The opportunity to view wildlife is one reason why many people visit District preserves. When viewing wildlife, please keep two things in mind: wildlife can be unpredictable, and we want to keep wildlife wild. As with any activity a degree of caution and common sense is necessary. Below are some general and specific guidelines to assist you.

General Guidelines

Keep your distance from wildlife, especially wildlife with young. Do not get between a mother and its young. Getting too close to any wildlife is very stressful on the wildlife and may pose a danger to you.

• Feeding wild animals is never appropriate. Wildlife can get sick from eating human food. Wildlife that is fed may become dangerously familiar with humans, which can result in serious injury or death to both people and animals.


• If an animal approaches you, it is your responsibility to move away to maintain a safe distance. Your safety is your responsibility!

Specific Guidelines

Rattlesnakes are native to this area and are more active in warm weather. Be careful stepping over logs, and be cautious of putting hands or feet under logs or rocks. In the event that you are bitten, remain calm and have someone hike out for help. Do not attempt to cut a bite or suck out venom. Seek professional medical assistance.

Mountain lions and coyotes are occasionally sighted in the open space preserves. If you see a mountain lion or coyote behaving aggressively toward people or pets, contact a ranger or the District office at (650) 691-1200 as soon as possible. If it is after 5pm on a weekday or on weekends call (650) 903-6395. The threat to public safety will be assessed and appropriate action will be taken.
