This report provides an overview of the alluvial fan characteristics and evaluates information on the significance of the biological and cultural resources to determine of the area meets the criteria to create a federal preserve.
To facilitate development of the Environmental Impact Statement which must accompany the Section 10 multi-species conservation proposal, a series of issue papers have been written. This study presents a brief look at outdoor recreation issues and describes the impacts of five alternative permit strategies might have on the County's ability to maintain recreation opportunities.
Survey results for wetland plant communities of the Agua Caliente Park and nearby La Cebadilla property.
