Invasion, Proliferation and Control of Invasive Aquatic Plants in Colorado State Parks

Nonnative aquatic species are invasive worldwide. These species adversely affect natural aquatic ecosystems in a variety of ways and can negatively affect agriculture, recreation and industry. This study addresses identification and control of aquatic plant species of concern in Colorado State Parks. Seventeen species identified as potential threats to the parks and safe, effective chemical control methodologies were determined for each species. A matrix was developed to include the plants, appropriate chemical controls and the type of aquatic habitat where chemical use would be safe and effective. The matrix and recommendations for its use will be provided to the Colorado Division of Parks and Outdoor Recreation to develop a management plan under Section 1204 of the National Invasive Species Act.

Improving urban park design: A comparative and analytical study addressing resources available and components necessary to improve the environmental and economic sustainability of urban parks

Urban parks have long been valued for the environmental, social, and economic benefits they provide. Increasingly, parks are also being recognized as features important for sustainable city design. This Capstone Project will identify, compare, analyze, and discuss means for designing sustainable urban parks. Recommendations for designing sustainable urban parks, based on project results, include: 1) ensure park features will support high levels of human activity; 2) use gravel to construct park trails; 3) purchase playground structures made of recycled materials; 4) plant a high number of perennials in flowerbeds and other vegetated areas; 5) plant climate-appropriate plants in vegetated areas; 6) ensure parks have high levels of plant diversity; and 7) develop future studies further exploring sustainable park design.
