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. -

Floristic Surveys of Saguaro National Park Protected Natural Areas William L. Halvorson and Brooke S. Gebow, editors Technical Report No. 68 United States Geological Survey Sonoran Desert Field Station The University of Arizona Tucson, Arizona USGS Sonoran Desert Field Station The University of Arizona, Tucson The Sonoran Desert Field Station (SDFS) at The University of Arizona is a unit of the USGS Western Ecological Research Center (WERC). It was originally established as a National Park Service Cooperative Park Studies Unit (CPSU) in 1973 with a research staff and ties to The University of Arizona. Transferred to the USGS Biological Resources Division in 1996, the SDFS continues the CPSU mission of providing scientific data (1) to assist U.S. Department of Interior land management agencies within Arizona and (2) to foster cooperation among all parties overseeing sensitive natural and cultural resources in the region. It also is charged with making its data resources and researchers available to the interested public. Seventeen such field stations in California, Arizona, and Nevada carry out WERC’s work. The SDFS provides a multi-disciplinary approach to studies in natural and cultural sciences. Principal cooperators include the School of Renewable Natural Resources and the Department of Ecology and Evolutionary Biology at The University of Arizona. Unit scientists also hold faculty or research associate appointments at the university. The Technical Report series distributes information relevant to high priority regional resource management needs. The series presents detailed accounts of study design, methods, results, and applications possibly not accommodated in the formal scientific literature. Technical Reports follow SDFS guidelines and are subject to peer review and editing. -

This research reflects the data available at the time this evaluation was conducted. Summary Pennisetum alopecuroides (Cenchrus purpurascens) appears to present a high risk of invasiveness in Illinois. The plant produces copious viable seeds which can be moved great distances by multiple means. Promoting fire and invading pastures could have a significant impact on other plants and animals, though evidence for these impacts is speculative. Populations in the wild in the US seem to be relatively recent. It's noted as an emerging invasive in the Mid-Atlantic states. Only one city and county in Virginia are currently listing it as invasive. Pennisetum alopecuroides therefore presents a risk and should be closely -

Garlic, an Approach to Healthy Life
Sharma N et al / IJRAP 2010, 1 (2) 358-366 Review Article Available online through www.ijrap.net NATURAL HEALING AGENT: GARLIC, AN APPROACH TO HEALTHY LIFE Nagori B.P., Solanki Renu, Sharma Neha* Lachoo Memorial College of Science and Technology, Pharmacy Wing, Jodhpur, India Received: 03-11-2010; Revised: 28-11-2010; Accepted: 03-12-2010 ABSTRACT We have grown up in the era of so-called wonder drugs. Garlic is one such drug which is grown globally. China is by far the largest producer of garlic, with approximately 10.5 million tonnes (23 billion pounds) annually, accounting for over 77% of world output. This leaves 16% of global garlic production in countries that each produces less than 2% of global output. The purpose of this study is to highlight new applications of cultivated as well as wild garlic in medicine. Areas of beneficial activity include anti- AIDS, anti-cancer and anti-cardiovascular disease and anti-infectious properties, amongst others. Garlic is uniquely the richest dietary source of many otherwise rare healthful sulphur compounds, plus organic selenium and germanium besides other essential nutrients and active health-promoting phytochemicals. Various forms of garlic are available, the most effective being fresh, powdered, distilled and especially aged garlic, which later lacks the irritant effect of fresh garlic, yet possesses equal or greater bio-active range and potency. Since many years cultivated garlic (Allium sativum) has served the medicinal purpose. As demand of garlic is continuously increasing due to its valuable features, other garlic species are screened for potential benefits of cultivated garlic with less side effects. -

Three-Cornered Garlic– a Garden Plant of Bygone Days, Not for the Park! Friends of Black Hill and Morialta Inc
Three-cornered Garlic – A Garden plant of bygone days, not for the Park! Native to north-western Africa and southern Europe. Three-cornered garlic is a bulb that flowers from August to November. There are suggestions on the internet that it is used in cooking by some people, but we don’t recommend this! It was once grown as a garden ornamental. Three-cornered garlic (Allium triquetrum) is a significant environmental weed in Victoria, South Australia, Western Australia and Tasmania. It is known to have serious impacts on the natural habitats that it invades as is very aggressive, having the potential to rapidly occupy large tracts of land. Three-cornered garlic (Allium triquetrum) forms dense and persistent stands that totally dominate the ground-flora when conditions are suitable. These stands crowd out and displace the indigenous grasses and groundcovers and can also seriously impede the regeneration of the over-storey vegetation. It is a common environmental weed of the Adelaide region in south-eastern South Australia and has been recorded in several other conservation areas in this state (e.g. in Marino Conservation Park, Sturt Gorge Recreation Park, Onkaparinga National Park, Belair Reserve, Belair National Park, Anstey Hill Recreation Park and Cleland Conservation Park). It prefers to grow along creek lines and other damp places. Don’t confuse Threecornered garlic with Burchardia umbellata (milkmaids) or Calostemma purpureum (garland lily), neither of these smell of garlic. When removing Three-cornered garlic, ensure the bulbs are removed and crushed.
