Biodiversity Catalog
of the Wildlife Sanctuary

The Wildlife Sanctuary was established in 1965 for students and the community to learn and explore the local wildlife. 

      • American Bullfrog

        This very large frog is native to the southeastern portions of the U.S. It is typically found in the late spring to summer. Males call with a low "Brrr-rummm" sound to attract females. This frog is an invasive species and is problematic because it eats native wildlife including other frogs, small birds, insects, fish, and even small rodents.

      • Gopher Snake

        This non-venomous snake typically eats small rodents such as gophers, mice, and rats. It kills its prey using its body to constrict. This photo was taken by Thu Anh Tran in March of 2015.

      • Red-eared Water Turtle

        This aquatic turtle is native to the southern U.S. It is very popular in the pet trade and many have been released into the wild all over the world (including our Sanctuary). It is listed as one of the top 100 most invasive species in the world by IUCN (International Union for Conservation of Nature). It eats aquatic plants, crayfish, snails, tadpoles, and fish. They are commonly seen basking on rocks or logs in the lake, swamp, or pond.

      • Western Fence Lizard

        The Western Fence Lizard is often called "Blue-Bellies" because of the bright iridescent blue patches of scales found on the along the sides of the body and throat. This lizard can be found in almost every location within the sanctuary during spring through summer. Males defend territories of rocks, stumps, or fallen tree branches and will display by dong "push-ups" to warn rival competitors. Western Fence Lizards eat various small insects. Found in almost every location from late winter into fall.

      • Coyote

        Coyotes are close relatives of domestic dogs. They generally weigh 30-40lbs when fully grown. Coyotes are extremely adaptable and will eat almost anything. In many areas, the majority of a Coyotes diet is vegetation. This picture was taken on the top of Mt. SAC hill (H3) using a motion activated camera with infrared flash.

      • Brush Rabbit

        A common type of cottontail rabbit with gray beneath the tail. This rabbit mainly feeds on forbes and grasses and is common all over Mt. SAC hill and surrounding areas (G1-G3). It is a food source for many of the sanctuary predators including Coyotes, Red-tailed Hawks, and Red-Shouldered Hawks.

      • Eastern Fox Squirrel

        The Eastern Fox Squirrel is native to the east coast of the United States and has been introduced into California. Primarily eats nuts and is a potential food source for predators such as large hawks. Often found in the Oak Woodland Areas of the Sanctuary (B4-C4).

      • Striped Skunk

        The Striped Skunk is typically about the size of a large house cat and has a black body with a white stripe along the back and forehead. Primarily forages at night and is omnivorous eating mice, eggs, insects, and carrion. It has a scent gland near the tail that is capable of producing an extremely powerful odor. It has few natural predators in the wild but will be eaten by large owls and occasionally Coyotes. This picture was taken using a motion activated camera with an infrared flash near the lake (A1).

      • Raccoon

        The Raccoon is a familiar mammal in most urban and suburban communities in California. It has a black mask over the eyes and yellowish white rings on the back and tail. The raccoon is omnivorous and will eat fruit, nuts, grains, insects, frogs, crayfish and practically anything else it can find. This picture was taken west of the stream (A3) using a motion sensing camera and infrared flash.

      • Mt. SAC Hill

      • Snow Creek Riparian

        Snow Creek Riparian – Snow creek enters the Wildlife Sanctuary along the north border by Temple Ave. and continues south.  It winds through the entire length of the sanctuary and eventually exits the Wildlife Sanctuary along the southern most border of the campus into Snow Creek in the city of Walnut.  Snow Creek is the only naturally existing water source in the sanctuary.

      • Bridge

        The newest bridge was installed in 2016 and was designed to bridge the gap over Snow Creek.  In the 1950’s, Mt SAC original entrance was located on this road which connected to Grand Ave to the South.  In 2013, the road and supporting structures collapsed resulting in a massive “sink hole”.  The new bridge and supporting barriers were designed to “day-light” the stream and allow for students and the community to safely cross Snow Creek which had been blocked off for about 70 years.

      • Oak Woodland

        Oak woodland is a widespread community in the hills of coastal California, vulnerable to urban sprawl. The flowers of oak trees (Quercusspp.) are wind-pollinated and the nuts they produce are called acorns. Acorns are an important part of the diet of many animals that inhabit oak woodlands including California ground squirrels, western gray squirrels, and acorn woodpeckers. 

        The acorn woodpecker is a species that is completely dependent on oak woodland. This bird stores acorns for use in winter in communal storage trees called granaries. Oaks are highly adapted to fire. Old trees have a thick, fire resistant bark that enables them to survive fairly hot fires. Fire is a natural component of the California landscape. Historically fires were caused by lightning strikes and carried by the dry grasses found beneath the oak canopy.

      • Meadow

          The Meadow consists of a few varieties of deciduous and evergreen trees and a large open area of wild radish, wild mustard, grasses and other low-growing plants. The animals that inhabit this area include terrestrial mammals and reptiles, along with a wide variety of seed and insect-eating birds. An array of Coastal Sage Scrub plants are located near the meadow and one of our smaller small group amphitheaters.

        • Swamp

          The swamp is an aquatic environment of shallow water containing primarily cattails and a few willows. Because of the shallow water it is comprised of mainly top feeding fish (the mosquito fish), tadpoles and crayfish. Fresh water swamps are one of the most productive fresh water systems. Cattails and sedges are found in and at the waters edge. Visitors include: Green Herons, Common Egrets, Snow Egrets, Great Blue Herons, and Black-crowned Night Herons.

        • Pond

          The pond is an enclosed body of water with a lot of floating and extruding aquatic vegetation. It is a nutrient-rich water system that supports a large number of organisms. Bullrush and cattails surround its perimeter. Red-winged blackbirds, Moore hens, and Mallards have nested in this body of water.

        • Lake

          The lake is our largest body of water in the sanctuary.  Generally, lakes are defined by having at least some regions significantly deep enough to prevent photosynthesis.  We use the term lake in our Sanctuary based on it’s size and it’s depth is more similar to an actual pond.  Visitors include: Green Herons, Common Egrets, Snow Egrets, Great Blue Herons, and Black-crowned Night Herons.
