Download or read book Use of Herbicides to Control the Spread of Aquatic Invasive Plants written by AG. Poovey and published by . This book was released on 2005 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive aquatic plants have become problematic in lakes and reservoirs across the United States. Infestations should be aggressively controlled to prevent degradation of water quality, fish and wildlife habitat, and the reduction of biodiversity. Operating under the purview of the US Army Corps of Engineers Aquatic Plant Control Research Program, the Chemical Control and Physiological Processes Team (CCPPT) develops and evaluates environmentally sound strategies for managing invasive aquatic and wetland plants using herbicides. Evaluations are conducted using a multi-tiered approach in customized controlled-environmental chambers, greenhouses, outdoor mesocosms, and pond facilities. The CCPPT employs methods consistent with the herbicide modes of action when conducting herbicide efficacy studies in small-scale experimental systems. Results from these studies are verified in aquatic and wetland field sites throughout the US. Coordination with the US Environmental Protection Agency and state regulatory agencies is undertaken to support the review and registration of new aquatic herbicides and amendments to established labels. Information and technology developed via research efforts are transferred to natural resource managers, the private sector, and the general public.

Download or read book Control of Invasive Plant Species in Created Wetlands written by G. Michael Fitch and published by . This book was released on 1994 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Virginia Department of Transportation (VDOT) has been using a herbicide in the form of glyphosate for the control of unwanted species in created wetlands. Results with this particular herbicide have been somewhat mixed. It was requested that the Virginia Transportation Research Council investigate other means of invasive species control that are being used or have been found to be effective and new products being developed. This report summarizes those methods of invasive wetland species control that have been researched within the past few years to determine if they could be utilized by VDOT. It was determined that the majority of the invasive species control methods that are not chemical in nature will not be feasible for use by VDOT at its created wetland sites (with the possible exception of pothole blasting with ammonium nitrate). Most of the herbicides reported on have been available and in use for several years. Although this is advantageous in that application methods have been refined, it does not appear that new, more effective chemicals will soon be available. It appears that glyphosate (Rodeo) is still one of the most effective herbicides available for control of invasive species in wetland settings due to its effectiveness on a wide variety of species and its benign effects on the surrounding environment.
Download or read book Optimising the Management of Invasive Aquatic Plants Targeted for Extirpation from Catchments and Waterways written by Daniel Clements and published by . This book was released on 2017 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Aquatic plants are integral components of freshwater ecosystems and provide essential ecosystem services. However, when invasive species establish in new aquatic environments, there are few natural checks and balances to inhibit their growth and spread. Overabundant aquatic vegetation can harm aquatic systems if left unchecked and negatively impact on agricultural productivity, social amenity and biodiversity values. Prevention and early intervention are recognised as the most cost effective means to manage invasive species that pose a biosecurity risk. This thesis contributes to the development of effective management strategies for one of the world's most invasive aquatic plant species, known as alligator weed (Alternanthera philoxeroides (Mart.) Griseb.). It focusses on developing management strategies in an early stage of invasion, in order to achieve extirpation of this species from catchments and waterways. Developing effective detection and surveillance strategies are required for invasive aquatic plants, as a key impediment to achieving extirpation is the ability to detect infestations, so that control strategies can be enacted. This thesis investigates the effectiveness of aerial surveillance for detection of alligator weed at different spatial scales, using high altitude aerial imagery (orthophotos) and unmanned aerial vehicle (UAV) technology. An examination of the growth rate of alligator weed in Victoria, Australia, over a five year period, demonstrates the effective use of orthophotos to detect and monitor large infestations of aquatic alligator weed. The efficacy of unmanned aerial vehicle technology, including the use of automated algorithms, to detect patches of alligator weed growing in waterways is evaluated against current detection techniques. Effective management of invasive aquatic plants targeted for extirpation requires the coupling of effective detection and control efforts to prevent reproduction. To date, development of control strategies for aquatic alligator weed has been limited to evaluating the efficacy of short-term control at a local scale without regard to the effects of management strategies on dispersal of propagules throughout catchments. This thesis determines that viable alligator weed stem fragments are produced following herbicide application, which comprises extirpation efforts. This thesis has gone further than current practice in that it has evaluated the efficacy of current and novel control techniques, in both laboratory and field trials and has developed methods to manage viable fragment production post-herbicide application, to limit dispersal throughout catchments. In this respect, the application of the herbicides glyphosate, metsulfuron-methyl and imazapyr, and their effectiveness when incorporating surfactant systems and plant growth regulators, have been evaluated in field and laboratory studies to optimise control techniques for aquatic alligator weed. Results have shown that our approaches, when used in an early stage of invasion, are capable of eliminating patches of alligator weed in two to three years. Integral to the research is an experiment to determine the effect of herbicide treatments on the production of alligator weed stem fragments and their subsequent viability. Further investigation to determine the usefulness of commercially available plant growth regulators (PGRs) to reduce the number of viable propagules produced by alligator weed post-herbicide application was found to be ineffective. This thesis also evaluates the impact of herbicides and surfactant systems, on all key alligator weed response metrics in aquatic environments including; above ground biomass, below ground biomass and viable stem fragmentation. No previous studies have looked simultaneously at these three important measures for determining the efficacy of a particular control regime, and we have determined that this is essential for effective management of aquatic alligator weed in an early stage of invasion. The thesis has underscored the notion that development of more effective management strategies, based upon experimental trials, will result in an increased likelihood of eradicating invasive aquatic plants that pose a biosecurity risk, and thus move toward the mitigation of the threat that high-risk species pose to aquatic ecosystems." -- Abstract.

Download or read book Beyond the War on Invasive Species written by Tao Orion and published by Chelsea Green Publishing. This book was released on 2015-06-17 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive species are everywhere, from forests and prairies to mountaintops and river mouths. Their rampant nature and sheer numbers appear to overtake fragile native species and forever change the ecosystems that they depend on. Concerns that invasive species represent significant threats to global biodiversity and ecological integrity permeate conversations from schoolrooms to board rooms, and concerned citizens grapple with how to rapidly and efficiently manage their populations. These worries have culminated in an ongoing “war on invasive species,” where the arsenal is stocked with bulldozers, chainsaws, and herbicides put to the task of their immediate eradication. In Hawaii, mangrove trees (Avicennia spp.) are sprayed with glyphosate and left to decompose on the sandy shorelines where they grow, and in Washington, helicopters apply the herbicide Imazapyr to smooth cordgrass (Spartina alterniflora) growing in estuaries. The “war on invasive species” is in full swing, but given the scope of such potentially dangerous and ecologically degrading eradication practices, it is necessary to question the very nature of the battle. Beyond the War on Invasive Species offers a much-needed alternative perspective on invasive species and the best practices for their management based on a holistic, permaculture-inspired framework. Utilizing the latest research and thinking on the changing nature of ecological systems, Beyond the War on Invasive Species closely examines the factors that are largely missing from the common conceptions of invasive species, including how the colliding effects of climate change, habitat destruction, and changes in land use and management contribute to their proliferation. There is more to the story of invasive species than is commonly conceived, and Beyond the War on Invasive Species offers ways of understanding their presence and ecosystem effects in order to make more ecologically responsible choices in land restoration and biodiversity conservation that address the root of the invasion phenomenon. The choices we make on a daily basis—the ways we procure food, shelter, water, medicine, and transportation—are the major drivers of contemporary changes in ecosystem structure and function; therefore, deep and long-lasting ecological restoration outcomes will come not just from eliminating invasive species, but through conscientious redesign of these production systems.
