Red-eared sliders like this one (identifiable by the small red stripe behind the eye) can be found in every section of Delta Ponds, competing for sunbathing real estate with other turtles. They are popular as pets, but considered invasive as they are not native to Oregon.
A western pond turtle and a male mallard sit together on a log secured to float on Delta Ponds. They can be found individually or in groups, basking in the sun on logs or taking a swim. The western pond turtle is Eugene’s only native turtle and is threatened due to invasive species and destruction of habitat from wetland draining reduced flooding. Their habitats have been separated into small patches by human activities, which leads to inbreeding and reduced genetic diversity.
The Western painted turtle is a subspecies of painted turtle found in the northern part of Oregon, western Ontario to British Columbia and south into the central United States.
They prefer slow-moving shallow water with dense aquatic vegetation, a muddy bottom, and lots of basking sites. Western painted turtles are marked with bright colors of red, yellow and olive on their neck, head, tail, legs and lower shell.
A bullfrog relaxes on a shallow bank of the northern ponds. Before major habitat restoration began, most pond edges were too steep for animals to easily transition between water and land. By flattening this terrain, it allowed for much greater interaction with the ponds for plants and wildlife.
An Oregon spotted frog floats in a patch of algae at Delta Ponds in Eugene, Oregon. They are found in or near a perennial body of water that includes zones of shallow water and abundant emergent or floating aquatic plants. In Oregon, this frog species is only known to occur in Wasco, Deschutes, Klamath, Jackson and Lane counties. The Oregon spotted frog is named for the black spots that cover the head, back, sides, and legs. The juveniles frogs body color is usually brown or, occasionally, olive green on the back and white or cream with reddish pigments on the under legs and abdomen. Adults range from brown to reddish brown in color, but tend to become more red with age. They are currently listed by the United States Fish and Wildlife Service as a threatened species due to loss of habitat, non-native plant invasions and introduction of exotic predators, such as bullfrogs and non-native fishes.
A juvenile fish swims through a murky patch of algae at the edge of Delta Ponds in Eugene, Oregon. The collection of ponds are home to multiple fish species like bluegill, largemouth bass, white crappie, and brown bullhead.
