Despite being an urban park, there are many types of wildlife. Studies have documented 318 species. This includes 23 species of non-native animals, which is seven percent. Non-native animals often adversely affect native flora and fauna by displacing or consuming animals and their habitat. For example, Feral Pigs are known to cause major ground disturbance from rooting and wallowing which leads to soil erosion and introduction of weeds. Feral Pigs also eat snakes, lizards, eggs, and disturb ground-nesting birds. The park is attempting to control the populations of some non-native species, focusing on those that cause the most damage to native plants and wildlife such as Feral Pigs.
