Executive Summary This survey was a continuation of several years of rare plant survey on San Juan Public Lands. Funding for the project was provided by San Juan National Forest and the San Juan Resource Area of the Bureau of Land Management. Previous rare plant surveys on San Juan Public Lands by CNHP were conducted in conjunction with county wide surveys of La Plata, Archuleta, San Juan and San Miguel counties, with partial funding from Great Outdoors Colorado (GOCO); and in 2004, public lands only in Dolores and Montezuma counties, funded entirely by the San Juan Public Lands. Funding for 2005 was again provided by San Juan Public Lands. The primary emphases for field work in 2005 were: 1. revisit and update information on rare plant occurrences of agency sensitive species in the Colorado Natural Heritage Program (CNHP) database that were last observed prior to 2000, in order to have the most current information available for informing the revision of the Resource Management Plan for the San Juan Public Lands (BLM and San Juan National Forest); 2.

  • Lake Havasu City Recommended Landscaping Plant List
    Lake Havasu City Recommended Landscaping Plant List Lake Havasu City Recommended Landscaping Plant List Disclaimer Lake Havasu City has revised the recommended landscaping plant list. This new list consists of plants that can be adapted to desert environments in the Southwestern United States. This list only contains water conscious species classified as having very low, low, and low-medium water use requirements. Species that are classified as having medium or higher water use requirements were not permitted on this list. Such water use classification is determined by the type of plant, its average size, and its water requirements compared to other plants. For example, a large tree may be classified as having low water use requirements if it requires a low amount of water compared to most other large trees. This list is not intended to restrict what plants residents choose to plant in their yards, and this list may include plant species that may not survive or prosper in certain desert microclimates such as those with lower elevations or higher temperatures. In addition, this list is not intended to be a list of the only plants allowed in the region, nor is it intended to be an exhaustive list of all desert-appropriate plants capable of surviving in the region. This list was created with the intention to help residents, businesses, and landscapers make informed decisions on which plants to landscape that are water conscious and appropriate for specific environmental conditions. Lake Havasu City does not require the use of any or all plants found on this list. List Characteristics This list is divided between trees, shrubs, groundcovers, vines, succulents and perennials.
