This book was released on 2012-12-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological invasion of native plant communities is a high-priority problem in the field of environmental management. Resource managers, biologists, and all those involved in plant communities must consider ecological interactions when assessing both the effects of plant invasion and the long-term effects of management. Sections of the book cover human perceptions of invading plants, assessment of ecological interactions, direct management, and regulation and advocacy. It also includes an appendix with descriptive data for many of the worst weeds.

This book was released on 2014 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dalmatian toadflax (Linaria dalmatica) has become a prolific invasive plant of rangelands in Oregon since its arrival in the early 20th century. In 2001, the Oregon Department of Agriculture initiated a release program promoting the distribution of the stem-boring weevil, Mecinus janthinus as classical biological control agent to reduce densities of Dalmatian toadflax and improve ecological integrity. This retrospective study sought to answer [1] What impact has M. janthinus had on reducing densities of Dalmatian toadflax, [2] Is M. janthinus spreading naturally to new sites, [3] Should ODA still facilitate spread of the agent, [4] If the program is successful, what is the long-term benefit acquired from this biological control program? These questions were answered using historical biological release forms and monitoring data, and a 2013 state-wide survey of Dalmatian toadflax and M. janthinus. The results show that M. janthinus has reduced average Dalmatian toadflax densities from 9.45 ± 1.34/m2 prior to release, to 5.5 ± 1.1/m2 after release. It was also found that the weevil has naturally migrated beyond their original release sites, and that there was no correlation between distance from release site and abundance of the weevil. These results indicate that ODA and its partners no longer need to distribute M. janthinus. Predictive modeling indicates that the current infestation of Dalmatian toadflax has reached 1% of its mean biological potential, while further expansion will be limited by the presence of M. janthinus. Reduction of plant density through biocontrol is of particular benefit to cattle production in Oregon where conventional control strategies of Dalmatian toadflax could reduce the annual value per acre of grazed land could be reduced by 6.5%.

This book was released on 2019 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dalmatian toadflax (Linaria dalmatica) is a listed noxious weed and invasive perennial forb across much of the western US. Native to the Dalmatian coast of Croatia, Dalmatian toadflax severely degrades rangeland ecosystems by competing with desirable species, replacing them with its unpalatable biomass. Finding an effective management method to combat this species is of utmost importance. A combination of multiple years of targeted grazing with sheep (Ovis aries) and the application of the broadleaf herbicide chlorsulfuron followed by a restoration reseeding were evaluated for efficacy and possible synergistic effects on a Dalmatian toadflax infested site at the F.E. Warren Air Force Base in Cheyenne, Wyoming. Grazing did not have an impact on Dalmatian toadflax cover or biomass, and did not increase the efficacy of chlorsulfuron. Herbicide treatments significantly reduced toadflax cover and biomass; however, native forbs were just as severely reduced, leading to a reduction in overall biodiversity in herbicide treated plots. Perennial grass cover and biomass were significantly increased in all treatments irrespective of herbicide use. Initial Dalmatian toadflax density, measured in percent cover, did not have an impact on herbicide and herbicide grazing treatment success, however higher initial density led to a greater post treatment density in grazing and control groups further suggesting that the grazing treatment alone was not sufficient for Dalmatian toadflax control. Greenhouse results and field sampling indicated that after one year the seeded species failed to successfully establish in the study site.

Available in PDF, EPUB and Kindle. Book excerpt: This encyclopedic yet easy-to-use 2-volume set covers 262 individual entries, including a full description of 451 species and another 361 plants compared as similar species, representing 63 plant families. 13 shortcut identification tables for groups that share similar, unusual, or relatively uncommon characteristics. 2 grass identification keys - a key to all characteristics including inflorescences and reproductive parts and a key to vegetative characteristics only. 67 tables comparing important characteristics of difficult-to-distinguish weedy species. Color photos of over 700 weeds including seeds, seedlings, flowers, and mature plants. Appendix of non-native plants rarely or occasionally naturalized in California. Glossary of botanical terms. Bibliography of some of the most pertinent publications. Index to common names, scientific names, and synonyms. Each entry describes the plant category, family name, common name, and synonyms along with a summary of the important aspects of the plant’s life cycle, size, growth form, impact, method of introduction, and toxicity. You'll also find a description of the seedling, mature plant, roots and underground structures, flowers, fruits and seeds, spikelets and florets, spore-bearing structures, and post senescence characteristics for each entry. Also includes a description of the habitat where each is typically found and distribution in California, other states, and worldwide, along with maximum elevation at which the species is found. Rounding out each entry is a description of the methods of reproduction, seed dispersal, germination requirements and conditions, seed survival and longevity, early establishment characteristics and requirements, cultural practices and management options that have proven effective or ineffective in controlling infestations, and a notation of the species' inclusion on federal or state noxious weed lists.

Download or read book Biological Control of Invasive Plants in the United States written by Eric M. Coombs and published by . This book was released on 2004 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Undesirable invasive plants are infesting public and private lands in this country at an alarming rate. These nonnative species destroy native habitats, threaten endangered plants and animals, interfere with recreation and transportation, and cause economic losses as land values and productivity decline. Various methods are used to suppress invasive plants, from herbicides to burning to cultivation. Classic biological control--in which selected host-specific, plant-attacking insects, mites, nematodes, and pathogens are introduced from the invasive plant's native lands--provides an additional tool for land managers to reduce invasive plant populations. In this volume, leading experts review the discipline of biological control of invasive terrestrial and aquatic plants. Topics addressed include the ecology and economics of biological control, monitoring, non-target impacts, a Code of Best Practices, and the processes of identifying, introducing, distributing, and maintaining biological control agents. In addition to chapters on the theory and practice of biological control, this book provides information about 39 target plants in the continental United States and 94 agents, including their origin, biology, habitat, impacts, and distribution. More than 300 color photographs help identify the plants and agents. The book concludes with information about invasive plants that are targeted for biological control in the future. An invaluable reference for land managers, natural resource and weed control specialists, and students of natural resource management, Biological Control of Invasive Plants in the United States provides practical, science-based information needed for understanding andusing biological control as part of an integrated invasive-plant management strategy.
