ABOUT THE COLLECTION

Desert Plants is a unique botanical journal published by The University of Arizona for Boyce Thompson Southwestern Arboretum. This journal is devoted to encouraging the appreciation of indigenous and adapted arid land plants. Desert Plants publishes a variety of manuscripts intended for amateur and professional desert plant enthusiasts. A few of the diverse topics covered include desert horticulture, landscape architecture, desert ecology, and history. First published in 1979, Desert Plants is currently published biannually with issues in June and December.

Digital access to this material is made possible by the College of Agriculture and Life Sciences, Boyce Thompson Southwestern Arboretum, and the University Libraries at the University of Arizona.

  • Plant Geography of Southwestern Sand Dunes

    Bowers, Janice E. (University of Arizona (Tucson, AZ), 1984)
    Patterns of plant distribution among eight dune fields in the southwestern USA and northwestern Mexico are analyzed and discussed. Each dune flora is characterized by three to five geographic components; the regional flora in which each dune field occurs is the dominant component. Endemic species, that is, species restricted to sand dunes, comprise ten percent or more of five of the eight floras. All possible combinations of the eight dune floras taken two at a time (28 pairs) were analyzed using Sorensen's similarity index. Only seven have a similarity value of 0.200 or greater. The lack of similarity among dune floras is due in part to their distribution among four floristically distinct biogeographic provinces and in part to localized recruitment of species from adjacent, non -dune plant communities. Geographic, edaphic and temporal barriers to dispersal and establishment also promote high dissimilarity among the eight floras. Eighty -three of the 533 species composing the eight dune floras are either endemic to sand dunes or occur at three or more of the dune fields studied. These 83 species fall into two subgroups: a group of 36 species characteristic of southwestern sand dunes east of 113° Longitude, and a group of 57 species characteristic of sand dunes west of 113° Longitude. Ten species are common to both groups. In the Southwest, dune fields are habitat islands, but dune floras do not behave in all respects as predicted by the MacArthur and Wilson theory of island biogeography. Southwestern sand dunes are not now floristic islands, but additional insular characteristics may develop over time.
  • Formation and Destruction of a Gila River Mesquite Bosque Community

    Minckley, W. L.; Clark, Thomas O.; Department of Zoology, Arizona State University; Center for Environmental Studies, Arizona State University (University of Arizona (Tucson, AZ), 1984)
    Evidence is presented for repeated formation and destruction of a Mesquite (Prosopis spp.) bosque community on a Gila River terrace, eastern Arizona. Terrace formation was induced by a coarse alluvial cone produced by flooding in an ephemeral tributary, followed by vegetative colonization culminating in Mesquite. Destruction was accomplished by sustained flooding in the mainstream Gila River.

  • Sub-surface Watering of Tree Seedlings in Arid Regions Using Discarded Plastic Infusion Sets

    Koarkar, A. S.; Muthana, K. D.; Central Arid Zone Research Institute (University of Arizona (Tucson, AZ), 1984)
    The difficulty of establishing tree plantations in arid regions, particularly on sandy and droughty soils, is a widely faced problem. Insufficient water is freely available in such regions for effective watering of tree plantations with conventional methods. Under such conditions, discarded plastic infusion sets from a hospital were tried for watering and establishing Anjan (Hardwickia binata). This allowed use of a limited quantity of water, in a regulated way as in the drip system, and watering directly in the sub -soil to reduce evaporation loss. Either one litre or half a litre of water was applied per plant this way every alternate day for the whole year, with total consumption of 173 litres and 91 litres of water respectively per plant in the entire year. Growth of these plants was compared with growth of ones subjected to conventional watering with 9 litres applied fortnightly to make 216 litres of water per plant for the period of the experiment. Plant growth even with a half litre treatment on alternate days was far superior to that with conventional watering.
