Yavapai Gardens Master Gardener Newsletter October/November 2016 University of Arizona Yavapai County Cooperative Extension Yavapai Gardens Master Gardener Newsletter October/November 2016 Watch out for the Jumping Cactus by Nora Graf You grew up in the desert if you know that cholla cactus would jump at you if you walked close to it. It is the plant equivalent of a rattlesnake. The good news is that cholla cactus does not wildly leap at you to defend itself, even if the nickname of jumping cactus persists. It is still a wicked plant to grow in your landscape if you have children or pets. On the other hand, the perception of the cactus jumping at you is well-deserved. Cholla consists of jointed thin cylinders. The connections between cylinders are weak and even the slightest brush can break that connection and the dense detachable spines will penetrate almost anything including skin, leather and clothing. The plant also sheds joints readily. When you are walking in the desert it’s easy to bump a joint loose with a foot or elbow. The spines latch on to any surface they touch. The tip of the spine slightly bends when it enters something and becomes a hook, making it difficult and painful to remove. I have personal experience so please take my word, IT HURTS! If you own pets, these can be an expensive choice. Pets tend to experience cholla face first and that means a trip to the vet. Humans get into trouble also. Unless you are like the person in the photo, chances are you can tolerate it. The larger spines can be pulled out with a pair of tweezers or pliers.

Hazlett, Michael H. Schiebout, and Paulette L. Ford Hazlett, Donald L.; Schiebout, Michael H.; and Ford, Paulette L. 2009. Vascular plants and a brief history of the Kiowa and Rita Blanca National Grasslands. Gen. Tech. Rep. RMRS- GTR-233. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 44 p. Abstract Administered by the USDA Forest Service, the Kiowa and Rita Blanca National Grasslands occupy 230,000 acres of public land extending from northeastern New Mexico into the panhandles of Oklahoma and Texas. A mosaic of topographic features including canyons, plateaus, rolling grasslands and outcrops supports a diverse flora. Eight hundred twenty six (826) species of vascular plant species representing 81 plant families are known to occur on or near these public lands. This report includes a history of the area; ethnobotanical information; an introductory overview of the area including its climate, geology, vegetation, habitats, fauna, and ecological history; and a plant survey and information about the rare, poisonous, and exotic species from the area. A vascular plant checklist of 816 vascular plant taxa in the appendix includes scientific and common names, habitat types, and general distribution data for each species. This list is based on extensive plant collections and available herbarium collections. Authors Donald L. Hazlett is an ethnobotanist, Director of New World Plants and People consulting, and a research associate at the Denver Botanic Gardens, Denver, CO.

Listed as the Gooseberry allotment by the Manti-La Sal National Forest (MLSNF), it has had a different name since 2012: White Mesa Cultural and Conservation Area (WMCCA), with reference to the nearby Ute Mountain Ute Tribe town of White Mesa. It also has a different man- agement situation: No cattle grazing, at least until 2021.

The cattle-free status of WMCCA was one of three reasons Sue Smith, a retired comput- er scientist and high school science teacher living in Prescott, Arizona, decided to study its native grasses for a Utah State University masters degree in Natural Resource Management.

Gen. Tech. Rep. RMRS-GTR-130. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 36 p. Abstract This checklist has 785 species and 801 taxa (for taxa, the varieties and subspecies are included in the count) in 90 plant families. The most common plant families are the grasses (Poaceae) and the sunflower family (Asteraceae). Of this total, 513 taxa are definitely known to occur on the Comanche National Grassland. The remaining 288 taxa occur in nearby areas of southeastern Colorado and may be discovered on the Comanche National Grassland. The Author Dr. Donald L. Hazlett has worked as an ecologist, botanist, ethnobotanist, and teacher in Latin America and in Colorado. He has specialized in the flora of the eastern plains since 1985. His many years in Latin America prompted him to include Spanish common names in this report, names that are seldom reported in floristic pub- lications. He is also compiling plant folklore stories for Great Plains plants. Since Don is a native of Otero county, this project was of special interest.

  • Native Plants of Deer Canyon Preserve Tree Cholla
    Native Plants of Deer Canyon Preserve Tree Cholla: January, 2009 When we find ourselves in the midst of winter, many of us especially appreciate a robust and vibrant flower such as the one produced by the tree cholla, Cylindropuntia imbricata. Even though we will not see these flowers in the flesh for at least another four months (assuming we receive some spring precipitation), the tree cholla is a signature plant of the Preserve and much of New Mexico that stands out at all times of the year. It is a long-lived perennial that grows in deserts, dry plains, and in piñon-juniper woodlands to an altitude of about 7500 feet. Closely related to the prickly pear cacti characterized by flat paddle-like stems (genus Opuntia, named after a Greek city), the chollas have only recently been separated from Opuntia into their own genus, Cylindropuntia, which is characterized by cylindrical stems. Consequently you will often see the scientific name Opuntia imbricata still being used to indicate the tree cholla. Imbricata refers to the overlapping, shingle-like appearance of the stem surface. Other common names used for this plant are cane cholla, chainlink cactus, cholla, walking stick cholla, and even teddy-bear cholla, leading to confusion with similar names for some of the other six species of Cylindropuntia native to New Mexico. Tree cholla is probably the most appropriate name for this plant as it is quite tree-like in appearance with its much-branched cylindrical stems and the fact that it can grow to 15 feet tall, but it usually ranges from 3 to 8 feet in height.
