Screenwhot Phragmites snorkeling: How does it survive water level fluctuations?

August 10, 2016

Brian Sorrell, Aarhus University Recording

PDF

This webinar focuses on the special adaptations that allow Phragmites survival in deep water, and how it responds to changes in water level. For Phragmites, staying alive means staying in contact with the air, with shoots acting as snorkels to transport oxygen down to the underground rhizomes. More frequent floods and fluctuations in water level are expected with climate change, so how will Phragmites cope with these changes? The speaker will explain the special, highly efficient gas transport in Phragmites stems and how recent discoveries about its gas transport are providing insight to its ability to survive different water regimes and water depths.

w20thumb Phragmites Management at Multiple Scales: Treatment Comparisons on the Great Salt Lake
February 25, 2016
Christine Rohal, Utah State University
Chad Cranney, Utah Division of Wildlife Resources
recording
PDF
Non-native Phragmites control research has been limited by the short temporal scales and small spatial scales of past experiments. Results from these limited studies may not apply at the scale that most restoration takes place. In this webinar, we will present four years of results from two large-scale Phragmitescontrol studies conducted on the shore of the Great Salt Lake, Utah. These studies examine the effectiveness of multiple control treatments at two spatial scales: large stands (1.2 ha/3 acres; the size of older, well-established invasions) and small patches (50 m x 20 m/0.25 acre; the size of newer invasions). The treatments evaluated in the large patch study are 1) untreated control 2) fall glyphosate spray, winter mow, 3) summer imazapyr spray, winter mow, 4) summer glyphosate spray, winter mow, 5) fall imazapyr spray, winter mow. The treatments evaluated in the small patch study include treatments 1-4 above plus 5) summer mow, fall glyphosate spray, 6) summer mow, then black plastic solarization. These studies also compare the plant communities that return after restoration efforts, data rarely evaluated in previous studies. Furthermore, given that non-native Phragmites spreads primarily by seed, we evaluated the ability of treatments to reduce seed production and spread. Join us for this webinar to see which management regime is the best for your site.Authors: Chad Cranney, Christine Rohal, Karin Kettenring & Eric Hazelton

Webinar19Thumbnail Remote Sensing Series Part II: Field and remote sensing methods to inform adaptive management of non-native Phragmites
December 10, 2015
Colin Brooks, Michigan Technological Research Institute recording
PDF
A large number of research results have been published in the scientific literature related to effective control of non-native Phragmites, especially in recent years. Also available are updated guides to non-native Phragmites management from state and local agencies. Through a grant from the University of Michigan Water Center, the Michigan Tech Research Institute has been integrating recent publications and results from non-native Phragmites control projects into a set of recommendations and remote sensing products to help with more effective non-native Phragmites control. Critical to the success of control efforts is applying the principles of adaptive management. Nutrient inputs, changing climate and water levels, historical management efforts including different combinations of control methods, and other factors have all impacted the current range of non-native Phragmites, which appears to still be expanding. Using field and remote monitoring to assess how these factors affect the success of control programs over time and then adapting control efforts based on those observations is likely to increase the success rate. Colin Brooks of Michigan Tech Research Institute will cover recent research results, the principles of adaptive management, and recommendations on how to apply them in this webinar.

PDF
Millions of dollars have been spent on the treatment of non-native Phragmites in wetlands using herbicide and other control methods, but few studies or management efforts have included an assessment of the effectiveness of treatment in terms of wetland habitat restoration. Through a grant from the University of Michigan Water Center, Michigan Tech Research Institute and Applied Ecological Services have been conducting analyses of field and remote sensing data in a nested design to develop standardized methods for monitoring treatment success. In this webinar, Dr. Laura Borgeau-Chavez of Michigan Tech Research Institute will share how, through field sampling, they have assessed paired treated and non-treated non-nativePhragmites dominant sites in Green and Saginaw Bays for biodiversity of birds, amphibians and vegetation. She will also show how both aerial and satellite imagery have been used to map treatment success at the landscape scale. The results of these field and remote sensing efforts show that treatment results are variable and monitoring and adaptive management are key strategies in fighting the invasion of non-native Phragmites.

Moore - Phrag webinar 28Apr2015 (2) Learning-focused decision support for management of Phragmites in the U.S. Fish and Wildlife Service Refuge System
April 28, 2015
C. Moore, University of Georgia recording
PDF
This webinar presents a new management decision support system that was developed for invasive Phragmites within the National Wildlife Refuge System of the U.S. Fish and Wildlife Service. Just like many land managers out there, Refuge managers wanted condition-specific guidance on how to treat patches of Phragmites, but, as you know, stands of Phragmites react differently to treatments across various habitat settings. Today you will learn about a tool developed by USGS in cooperation with Refuge personnel to help solve this problem.

PhragmitesPart2Osterland Full Phragmites and Prescribed Fire: Seasonal Prescriptions and Risk – Part 2
March 12, 2015
L. Osterland, MI Department of Natural Resources Part 2 recording
PDF
Part 1 recording (hosted by LSFSC)
This webinar is part two of a series developed through a partnership between Great Lakes Phragmites Collaborative and the Lake States Fire Science Consortium (LSFSC). Part one was hosted by LSFSC.We know that prescribed fire, as part of an integrated management regime, can be an important tool for successfully managing Phragmites australis. However, large Phragmites stands can create particularly challenging burn situations. With stalks that can be 15 feet tall, fires that create large amounts of smoke and particulates, quick spread rates, and extreme heat outputs, even experienced burn crews are put to the test. Part One of this series focused on the fire science of burning Phragmites, including how fuel loads are altered, the seasonality of fire and different prescriptions and modeling, blending fire operations with opportunities and risks, and the social and ecological drivers that are behind the considerations to use this high risk strategy. This webinar is the second in the series and it covers the “How To” of burning Phragmites, with a focus on fire management and operations, burn unit layout, equipment and crew needs, differences in prescriptions and crew needs based on season, public perception, smoke management, safety of crew and public, and constraints and opportunities.

Mozdzer Phragmites Webinar 2014-11-12 final - lower resolution Phragmites and Climate Change
November 12, 2014
T. Mozdzer, Bryn Mawr College recording
PDF
Previous studies have shown that wetland ecosystems respond strongly to variation in nitrogen pollution, atmospheric carbon dioxide, and hydroperiod. Changes in these factors can alter the ability of wetland ecosystems to persist in a rapidly changing climate. At the same time, wetlands are also under siege by the introduced lineage of Phragmites australis, which has the potential to be a “game-changer” due to its ability to alter the structure and the function of wetlands. In this presentation, Tom Mozdzer summarizes his findings and discusses the effects of nitrogen pollution and elevated CO2 on both native and introduced lineages of Phragmites. His research suggests that increasing CO2 concentrations combined with N pollution will likely exacerbate the invasion of introduced Phragmites due to its greater phenotypic plasticity. He talks about the traits that make the introduced lineage so successful under current and near-future conditions and provide some management insights.

EH_webinar Phragmites Management in the United States: 40 years of Methods and Outcomes
September 30, 2014
E. Hazelton, Utah State University recording
PDF
After more than 40 years of history researching and managing Phragmites in the US, there are many anecdotes and local preferences on management techniques. Some management actions are impacted by local culture or legislation. As land managers, restoration practitioners, and researchers, we are more likely to achieve our objectives with a broad selection of tools, and knowledge of the situations where certain techniques might fare better than others. The literature has a strong emphasis on herbicide treatment for Phragmites management, whether alone, or in combination with other techniques. More research on alternate methods could benefit both private landowners and managers in areas that are sensitive to herbicide use. This webinar is presented in the context of a conceptual model of a Phragmites invasion that depicts the role of nutrients and disturbance on Phragmites’ sexual reproduction and spread. The model helps build recommendations on how to make wetlands less invasible. Additionally, the speaker will discuss recent results from several studies on Chesapeake Bay that focus on prioritizing when and where to manage Phragmites. More holistic management regimes that involve improving water quality, decreasing disturbance, and revegetation will have the greatest likelihood of recovery from invasion. The aim is to enable managers to prioritize their management actions to areas where they are most likely to achieve management objectives.

Michigan DEQ website/tools/guide
This webinar focuses on the prioritization of Phragmites management. Invasive phragmites has spread throughout the great lakes region and securing funding and resources to manage Phragmites long-term is a constant challenge. The Michigan Department of Environmental Quality has developed a prioritization tool and user guide to help management groups prioritize the treatment and management of invasive Phragmites in Michigan. The prioritization tool uses three categories of criteria – ecological, human values, and feasibility/coordination of treatment – as factors to score and ultimately prioritize invasive Phragmites management. The speakers provide an overview of the Phragmites prioritization tool and will share the recently updated Michigan Phragmites Management User Guide.

Phragmites presentation revised TJackson Invasive Species Management: State Department of Transportation Perspectives
June 19, 2014
P. Dunleavy, NY State Department of Transportation and T. Jackson, IL Department of Transportation recording
PDF
This webinar focuses on roadside management of invasive species including Phragmites, and the role of State Departments of Transportation. Roadside ditches are a major vector for Phragmites and other invasive plants. State Departments of Transportation (DOTs) have jurisdiction over large rights-of-way which form pathways where Phragmites and other invasive plants can move through the landscape. These pathways, combined with land disturbance for capital projects and maintenance, plus mowing and other regular movement of vehicles and materials combine to pose significant invasive species control challenges. The speakers share background information about DOTs involvement with invasives, including training, staffing, and their experiences managing invasive plants, the use of GIS in mapping and management, and the importance of partnerships.

hqdefault Emerging Research: BioControl
December 13, 2013
B. Blossey, Cornell University recording
This webinar is focused on Biocontrol which is a promising strategy to control Phragmites and other invasive plant species. Non-native plant species are often successful in new environments due to a lack of natural predators. Occasionally scientists are able to identify a natural predator and intentionally release them in the hope of curbing the invasive species population. Introducing a non-native species is a complicated issue and requires rigorous testing and evaluation before such a release is approved.

GLRIWebinar112213 Emerging Research: Gene Silencing
November 22, 2013
E. Golenberg, Wayne State University recording
PDF
This webinar is focused on Gene Silencing which is a promising strategy to control of Phragmites or other invasive plant species. Scientists have known for some time that protein production can be disrupted by preventing the protein-coding instructions of messenger RNA from reaching the ribosomes, which are the sites of protein synthesis. If a gene cannot send its code, the protein cannot be made, and the trait that is mediated by the protein is then not realized. One process of interfering with the translation of messenger RNA into protein is known as “gene silencing.”

Kettenring GLC seminar_FINAL Seeds, Stolons and Rhizomes. Oh My! Pathways of introduction and spread of non-native Phragmites.
October 3, 2013
K. Kettenring, Utah State University recording
PDF
This webinar focuses on the mechanisms of Phragmites spread. Until recently, it was believed that the spread of non-native Phragmites was driven by rhizomes in the soil, and that the seeds very had low viability. Recent research suggests that spread via seed dispersal is more significant than previously thought. The speaker discusses how Phragmites spreads, the impact of genetic diversity and nutrient enrichment on viable seed production, and the implications of spread by seed for Phragmites management.

OGL Phragmites_8_8_13 Beyond the Burn — Managing Phragmites Using an Adaptive Management Framework
August 8, 2013
R. Fahlsing and B. Clancy, MI Department of Natural Resources recording
PDF
This webinar focuses on the long-term management of Phragmites using an ecosystem approach. Millions of dollars are spent each year to manage non-native Phragmites within the Great Lakes Region. However, Phragmites management is a long-term multistep process that requires: careful planning, site prioritization, clear delineation of management objectives, knowledge of specific management techniques, and a plan for evaluating success. The speakers share their experience managing Phragmites long term and how to move away from the mindset of killing Phragmites and into an adaptive management framework aimed at ecosystem management.

JGilber Phrag talk_April 5 2013 Can We Manage Without Herbicide? Lessons Learned from the Ontario Experience
April 5, 2013
J. Gilbert, Wetland Ecologist, Ontario recording (intro missing; content included below)
PDF
This webinar today focuses on the Phragmites management and the role of herbicide. For many, herbicide application is the first line of defense against both emerging and established populations of Phragmites, and while it can be very effective when applied correctly, it’s also expensive, can impact desirable wetland plants, and is not a permanent solution. In some areas, including application of herbicides over water is not permitted. The speakers focus on the role of herbicides in Phragmites management and some of the challenges and strategies of dealing with phragmites management in Ontario.

Great Lakes Phragmites Collaborative Webinar 1 (overview) Introducing the Great Lakes Phragmites Collaborative
July 19, 2012
H. Braun, Great Lakes Commission and K. Kowalski, U.S. Geological Survey recording
PDF
The establishment and rapid spread and of invasive Phragmites across the Great Lakes poses many challenges for habitat managers, private landowners, researchers and other entities. Several local initiatives have been initiated to addressing Phragmites management in discrete geographic areas; however, there are few opportunities to communicate with others, share successes and challenges, and catch up on the latest research. Further, there is no comprehensive resource dedicated to Phragmites management and research in the Great Lakes. The Great Lakes Commission is partnering with the USGS – Great Lakes Science Center and Ducks Unlimited, to develop an interactive website and webinar series to encourage technology transfer, information sharing, and network building. The Great Lakes Phragmites Collaborative will engage the natural resource community, provide resources and tools to improve collaboration and lead to more coordinated, efficient and strategic approaches to Phragmites management and restoration.
