  • 3 Invasive Species in the Sonoran Desert Region

    3 Invasive Species in the Sonoran Desert Region

    3 Invasive Species in the Sonoran Desert Region 11 INVASIVE SPECIES IN THE SONORAN DESERT REGION Invasive species are altering the ecosystems of the Sonoran Desert Region. Native plants have been displaced resulting in radically different habitats and food for wildlife. Species like red brome and buffelgrass have become dense enough in many areas to carry fire in the late spring and early summer. Sonoran Desert plants such as saguaros, palo verdes and many others are not fire- adapted and do not survive these fires. The number of non-native species tends to be lowest in natural areas of the Sonoran Desert and highest in the most disturbed and degraded habitats. However, species that are unusually aggressive and well adapted do invade natural areas. In the mid 1900’s, there were approximately 146 non-native plant species (5.7% of the total flora) in the Sonoran Desert. Now non-natives comprise nearly 10% of the Sonoran Desert flora overall. In highly disturbed areas, the majority of species are frequently non-native invasives. These numbers continue to increase. It is crucial that we monitor, control, and eradicate invasive species that are already here. We must also consider the various vectors of dispersal for invasive species that have not yet arrived in Arizona, but are likely to be here in the near future. Early detection and reporting is vital to prevent the spread of existing invasives and keep other invasives from arriving and establishing. This is the premise of the INVADERS of the Sonoran Desert Region program at the Arizona-Sonora Desert Museum.

The Natural Resource Technical Report Series is used to disseminate results of scientific studies in the physical, biological, and social sciences for both the advancement of science and the achievement of the National Park Service mission. The series provides contributors with a forum for displaying comprehensive data that are often deleted from journals because of page limitations. All manuscripts in the series receive the appropriate level of peer review to ensure that the information is scientifically credible, technically accurate, appropriately written for the intended audience, and designed and published in a professional manner.

    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.

    Flora and Vegetation of the Mohawk Dunes, Arizona, Felger, Richard Stephen

    FLORA AND VEGETATION OF THE MOHAWK DUNES, ARIZONA Richard Stephen Felger Dale Scott Turner Michael F. Wilson Drylands Institute The Nature Conservancy Drylands Institute 2509 North Campbell, #405 1510 E. Fort Lowell 2509 North Campbell, #405 Tucson, AZ 85719, U.S.A. Tucson, AZ 85719, U.S.A. Tucson, AZ 85719, U.S.A. [email protected] ABSTRACT One-hundred twenty-two species of seed plants, representing 95 genera and 35 families are docu- mented for the 7,700 ha Mohawk Dune Field and its immediate surroundings, located in Yuma County, Arizona, USA. Three major habitats were studied: dunes, adjacent sand flats, and playa. The dunes (including interdune swales) support 78 species, of which 13 do not occur on the adjacent non-dune habitats. The adjacent non-dune habitats (sand flats and playa) support 109 species, of which 43 were not found on the dunes. The total flora has 81 annual species, or 66% of the flora. The dune flora has 63 annual (ephemeral) species, or 81% of the flora—one of the highest percentages of annuals among any regional flora. Of these dune annuals, 53 species (84%) develop during the cool season. No plant taxon is endemic to the Mohawk region. There are 8 dune, or sand adapted, endemics— Cryptantha ganderi, Dimorphocarpa pinnatifida, Dicoria canescens, Ditaxis serrata, Pleuraphis rigida, Psorothamnus emoryi, Stephanomeria schottii, Tiquilia plicata—all of which are found on nearby dune systems. Two of them (C. ganderi and S. schottii) are of limited distribution, especially in the USA, and have G2 Global Heritage Status Rank. There are four non-native species in the dune flora (Brassica tournefortii, Mollugo cerviana, Sonchus asper, Schismus arabicus), but only Brassica and Schismus seem to pose serious threats to the dune ecosystem at this time.
