This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study focused on an invasive riparian reed grass, Arundo donax L., a clonal plant of the family Poaceae that is widely distributed in North America. Water availability, including water taken up from the roots locally or transported from the neighboring ramets, may affect the performance of A. donax in riparian zones. The first objective was to find out how moisture gradients affected the performance of A. donax in riparian zones. I measured leaf photosynthetic rate, leaf [delta]13C ratio, and plant growth-related parameters across two summer growing seasons at four transects perpendicular to the water course on the Rio Grande in South Texas. The second objective was to find out whether physiological integration existed in A. donax and how resource sharing, if any, affected plant growth. A rhizome severing experiment was conducted on five paired plots to compare growth-related parameters between plots with rhizomes severed and intact at 3, 7, and 11 weeks after treatment. Heavy water ([delta] 2H ~18000́/00) was applied on three 1-m2 area over 3 successive days and rhizome samples were collected beyond the watering zone after 5, 24, and 48 hours of last watering. At short-term scales, A. donax performance was adversely affected by both drought and inundated conditions; over longer time scales, plant performance decreased as water availability declined in general, but biomass and stem density were similar across moisture gradients. I also found evidence of physiological integration in A. donax. Water was transported through interconnected rhizomes at least 3.5 m; transport distances averaged 1.67 m. Rhizome severing stimulated higher ramet production initially but over longer periods produced shorter thinner stems with lower flood tolerance. However, after 11 weeks of re-growth, plot-level biomass was similar between plots with severed and intact rhizomes. These results suggest that performance of A. donax is affected by water availability in riparian zones; however, clonal plant plasticity, water use efficiency, and clonal integration ameliorate impacts of water stress on the performance of A. donax. Such traits enhance its resource use, which could potentially increase competitive ability rate of establishment, and extent of this invasive species in heterogeneous riparian environments.

Download or read book The Influence of Dams on the Abundance of Arundo Donax giant Reed in Riparian Corridors written by Christian J.C. Commander and published by . This book was released on 2013 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changes to the natural (historical) disturbance regime of riparian ecosystems can increase the likelihood of invasion by non-native plant species. Dams increase non-native plant species invasion into riparian ecosystems by altering hydrological regimes and geomorphology of riparian systems. Arundo donax L. (commonly, giant reed) is a perennial grass that is an aggressive invasive species in riparian habitat throughout California and other subtropical regions. It can displace native plant species, reduce habitat quality for native wildlife, and pose serious challenges for conservation management and ecological restoration of degrated habitats.

Download or read book Prioritizing the Management of Arundo Donax Recommendations for Removal and Revegetation in California Riparian Habitats written by Matthew S Waterworth and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The highly invasive grass species, giant reed (Arundo donax), has been a major contributor to riparian habitat degradation in California for over 50 years. Several modes of vegetative reproduction have allowed this alien species to take advantage of fluvial processes and rapidly spread within California watersheds. A. donax dramatically alters hydrologic regimes, displaces native vegetation, and removes food and habitat for native wildlife. It is widely accepted that removal of this invasive on a watershed scale is critical to restore natural riparian processes and facilitate the reestablishment of native flora and fauna. The following study analyzed the efficacy of past eradication projects and the subsequent recovery of native vegetation through either passive or active means. Through this analysis, recommendations were made for prioritizing removal sites, determining the most effective removal methods, and employing passive or active revegetation. This study determined the the three highest priority removal sites applicable to a wide variety of California watersheds are: upper watershed, largest A. donax infestations, and infestations in close proximity to fire prone areas. The most cost-effective removal method for large A. donax clumps is foliar spray with a 3-6% glyphosate solution. To minimize the use of herbicide and remain within the legal limit of 7qt/acre, mechanical removal should be used for large infestations whenever access allows for the use of heavy machinery, especially near urban areas. For moderate to small clumps, the most effective control methods are “bend and spray/hook” (3-6% glyphosate) and “cut-stem,” (100% glyphosate). Cut-stem is recommended near urban areas to avoid overspray or when A. donax is mixed in with native vegetation. If active revegetation is required, all A. donax should be removed prior to revegetation to eliminate the threat of reinvasion; the only exceptions to this are when it is necessary to immediately restore habitat for sensitive species or when erosion is a major concern. Due to the high costs of active revegetation and the lower ecological value of artificially plant riparian forests, passive revegetation should be used whenever possible. A. donax eradication on a watershed scale is feasible with proper planning, but the process may take 20 years or more depending on the size of the infestation.

This book was released on 2011-08 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasions of non-native plants into forests of the Southern United States continue to go unchecked and only partially un-monitored. These infestations increasingly erode forest productivity, hindering forest use and management activities, and degrading diversity and wildlife habitat. Often called non-native, exotic, non-indigenous, alien, or noxious weeds, they occur as trees, shrubs, vines, grasses, ferns, and forbs. This guide provides information on accurate identification of the 56 non-native plants and groups that are currently invading the forests of the 13 Southern States. In additin, it lists other non-native plants of growing concern. Illustrations. This is a print on demand edition of an important, hard-to-find publication.

Available in PDF, EPUB and Kindle. Book excerpt: Non-Chemical Weed Control is the first book to present an overview of plant crop protection against non-food plants using non-chemical means. Plants growing wild—particularly unwanted plants found in cultivated ground to the exclusion of the desired crop—have been treated with herbicides and chemical treatments in the past. As concern over environmental, food and consumer safety increases, research has turned to alternatives, including the use of cover crops, thermal treatments and biotechnology to reduce and eliminate unwanted plants. This book provides insight into existing and emerging alternative crop protection methods and includes lessons learned from past methodologies. As crop production resources decline while consumer concerns over safety increase, the effective control of weeds is imperative to insure the maximum possible levels of soil, sunlight and nutrients reach the crop plants. Allows reader to identify the most appropriate solution based on their individual use or case Provides researchers, students and growers with current concepts regarding the use of modern, environment-friendly weed control techniques Presents methods of weed management—an important part of integrated weed management in the future Exploits the knowledge gained from past sustainable weed management efforts

Available in PDF, EPUB and Kindle. Book excerpt: The volcanic and oceanic nature of the Canary Islands, its rich plant biodiversity and high rate of endemism, as well as the relict character of some of its plant communities make it a territory of great biological interest. The main geographic, climatic, bioclimatic, biogeographic and floristic features of the Islands are shown and related to the distributional pattern of potential communities along an altitudinal gradient. Current vegetation units and their ecology are described and illustrated with numerous pictures. Potential vegetation units are summarized and comprehensive maps of the potential natural vegetation for each island are given. Human impact on the natural landscape, the occurrence of invasive plants, and the probable impact of climate change on the flora and vegetation are discussed. The conservation status of flora and vegetation are assessed. Four appendixes include a syntaxonomical scheme, a brief history of botanical studies and explorations in the Islands, ethnobotanical notes, and a list of selected literature.
