Can I reserve the outdoor pavilions for a party at either the Environmental Education Center in Alviso or the Visitor Center in Fremont?
The pavilions are for refuge environmental education programs and refuge programs.  If they are not in use by the refuge, visitors are welcome to use them on a first-come basis.  It may be best to call the refuge to see if a program is planned for that day.  Call 510-792-0222 ext. 476 for Fremont, or 408-262-5513 for Alviso.  The policy for appropriate use is posted at each of the pavilions.

Why can't I fly a kite, have barbecues, or play loud music?  Why are your rules different from the other parks nearby?
The Don Edwards San Francisco Bay National Wildlife Refuge is a federal wildlife refuge and its main purpose is to preserve habitat and wildlife.  Federal laws state that only activities that are compatible with refuge management and help conserve habitat are allowed.  This includes enjoyment of the refuge through wildlife-oriented recreation such as bird watching, environmental education and interpretation, nature observation, etc.  Certain activities such as kite flying and loud music disturbs wildlife and does not promote conservation.

I found an injured animal.  Can I bring it to your refuge?
Refuge staff are land managers and are not trained to rehabilitate animals.  Injured wildlife could be brought to Ohlone Humane Society in Newark which is only a five-minute drive from the refuge offices in Fremont.  Call them at 510-792-4587.

Why do you allow duck hunting on a wildlife refuge?
Hunting as been determined by Congress to be an acceptable wildlife-oriented activity as long as it does not harm the population and does not interfere with refuge management, and should be included if possible.  The reasoning is that hunting would not be possible if wildlife populations are poor and habitat is not managed correctly.  All hunters must purchase a Federal Duck Stamp.  The proceeds from the sale of Duck Stamps are used to purchase additional wetlands for conservation.  Click here for more information about Federal Duck Stamps and the amount of land purchased since the program began.
