`Ahakhav Tribal Preserve CRIT 6-FC-CU-CT110 $45,800 The goal of this project is to restore native riparian vegetation within a designated Tribal Preserve (ie., park) on the reservation along the lower Colorado River near Parker, AZ. The tribe constructed and operated its own nursery to grow root stock in preparation for this revegetation project. A total of 75 acres of park land along the river was cleared of dense tamarisk and other non-native plants. Native willows, mesquite and cottonwood trees from the nursery were planted and maintained by means of a drip irrigation system to increase survival of planted materials. After the first year, planted stock will establish root systems down to the natural water table and be able to grow without further irrigation. Vegetative growth and survival has been impressive. Eventually, the Tribe wishes to restore the entire Preserve (several hundred acres) to natural riparian and wetland conditions for the education and enjoyment of tribal members. Native riparian vegetation has been severely impacted by reduced surface and groundwater flows resulting from upstream impoundments. Fish and wildlife diversity has been consequently impacted by loss of riparian habitats. Grand Junction Wetlands Western Colorado Botanical Society 6-FC-CU-BS110 $6,500 The Western Colorado Botanical Society completed a feasibility analysis on the development of a wetland/natural area adjacent to Watson Island and the Colorado River in the City of Grand Junction. The final report ""Colorado River Outdoor Laboratory, Feasibility Analysis and Conceptual Design Report" dated June 1998, establishes the feasibility of creating about 1.53 acres of wetland on the property composed of ponded areas supported by groundwater and by direct diversions of water from the Colorado River. Pond edges would be seeded and planted with a mixture of wetland plant species. In addition, the plan calls for enhancing existing wetlands by removal of fill material and debris and replacing the invading exotic plants with native trees, shrubs and herbaceous plants. Riparian enhancement on 3.57 acres of the property is proposed by means of exotic plant control, regrading of the terrain to a more favorable contour and replanting of native riparian species, notably cottonwood. Bat Population and Gave Survey NAU 6-FC-CU-UA110 $27,000 Northern Arizona University completed a survey of bat populations and bat cave resources along the Colorado River from Glen Canyon Dam through Grand Canyon National Park. Construction of Glen Canyon Dam inundated miles of canyon and likely destroyed bat roosting and nesting caves. Surveys resulted in
