  • Roosevelt's Legacy

    President Theodore Roosevelt with Gifford Pinchot

    In 1903 President Theodore Roosevelt established the Pelican Island Bird Reservation, the first of 50 refuges he would create during his time in office and the roots of what is today known as the National Wildlife Refuge System. Seen here with Gifford Pinchot, President Roosevelt's legacy is reflected at San Bernardino National Wildlife Refuge, a landscape set aside and managed for the benefit of wildlife.
