Research and educational activities:
The park serves 3 - 4,000 educational program participants yearly, with a variety of thematic nature walks and programs on such topics as Bald Eagles, waterfowl, and migration. Trained volunteers lead bird programs and conduct bird surveys. The on-site Carson Nature Center reaches over 11,000 visitors a year.
Conservation/Management Issues
Serious threats:
- invasive/non-native plants (Canada thistle, leafy spurge, diffuse knapweed);
- habitat conversion and development of surrounding area.
Minor threats:
- introduced animals;
- cowbird parasitism.
Potential threats:
- pollution;
- disturbance to birds;
- hydrologic changes.
Efforts to address threats:
A program of chemical, cultural and biological weed control has been in place for 10-15 years. Park managers have been restoring grassland areas with native grasses, creating and enhancing wetlands, and planting native trees and shrubs to improve riparian habitat. The "South Platte Park Buffer Plan," adopted by the city of Littleton and the South Suburban Park & Recreation District, includes strategies to purchase land, down zone, utilize conservation easements, and create vegetated buffers on adjacent properties. Bird habitats within the park are protected through the designation of "wildlife areas," the use of which is restricted in type and extent.
