An oak woodland works along the north-facing hillsides. The park's wildlife habitats are fragile, rare and necessary for the survival of over 100 federally endangered plants and animals. The Rose Creek watershed is local in nature extending no further east than Scripps Ranch. The creek naturally meanders around the canyon floor, which continues to deepen and widen. It soon drains into Mission Bay.
Resident wildlife includes raccoon skunks, rabbits, coyotes, foxes, and mule deer.
The raptors flying above Rose Canyon are some of the most majestic animals anywhere, including many varieties of owls and large hawks. Volunteers are always welcome to help with the maintenance and operation of the park. Park Rangers offer interpretive walks and programs.
