Flowering Rush Biology, Management, and Control
September 15, 1 p.m. CT
Presented by: Dr. John D Madsen, US Department of Agriculture, Agricultural Research Service, Invasive Species and Pollinator Health Research Unit, Davis, CA.
Flowering rush (Butomus umbellatus L.) is becoming a widespread invasive weed in the waters of the West and Midwest. Flowering rush causes a number of nuisance problems including obstruction shorelines, reducing irrigation flow, and providing habitat for nonnative warmwater fish. This species is distinctive in appearance, though is often confused with other emergent and submersed species. Flowering rush occurs as both diploid and triploid biotypes, but western US populations are largely the triploid biotype. Recently published research has identified six genotypes in the US, but one genotype in particular dominates in the western US. While an international group is actively looking for biological control agents, at this time no insect biocontrol agents are available. Several herbicides are available and effective for chemical control of flowering rush, with three application modes studied: foliar application to emergent leaves, submersed inject to submersed leaves, and bare-ground applications to newly-sprouted plants in the spring. Preemergent applications have also been studied. While harvesting has been used to manage foliage, it is not a long-term management technique. Various physical techniques, such as digging and bottom barriers, have also been used. Whichever technique is used, it is essential that the manager target the rhizome bud stage to reduce propagule production.
John D. Madsen, PhD. is Research Biologist with the US Department of Agriculture, Agricultural Research Service, Invasive Species and Pollinator Health Research Unit in Davis, California, USA. His work focuses on the biology, ecology and management of aquatic plants, particularly nuisance-forming species.
Forestry BMPs for Invasive Species
October 20, 1 p.m. CT
Presented by: Bernie Williams, Plant Pest and Disease Specialist, Division of Forestry – Forest Health, Wisconsin Department of Natural Resources
BMPs – Best Management Practices for Forestry Invasive Species are voluntary practices that were developed to coincide and complement Legislative Rule NR 40 https://docs.legis.wisconsin.gov/code/admin_code/nr/001/40.pdf which works as a way of classifying Invasive Species across the board. The BMPs are designed to be a practical response when addressing Invasives in a forested setting when logging practices are in place. They were adopted in September of 2009 and since that time we have trained thousands of Foresters, Loggers and Landowners on the practicality of implementing prior to planning a harvest especially when Invasive species are present.
Bernie has been with the WI DNR for 13 years working with Invasives Species, and particularly the Best Management Practices (BMPs) for addressing Invasives in the Forests. She loves science and biology and everyday is surprised by how exciting and dynamic it continues to be. Bernie is originally from Pennsylvania and went to the University of Pittsburgh (PITT) for both undergrad and grad school. She loves to garden and has an active bee hive in the middle of her vegetable garden.
USGS and USFWS collaborative project to conduct a national horizon scan for organisms in trade
November 17, 1 p.m. CT
Presented by: Wes Daniel, USGS
Invasive species are one of the greatest threats to the United States (U.S.) biodiversity and have cost the U.S. over $120 billion in damages each year (Pimental et al. 2005). The impacts of invasive species range in size and scope from small-scale and localized up to broad shifts in ecosystem function and can influence economically essential species and those of conservation concern alike. The consequences of an invasion include not only degradation of the natural ecosystem but also economic repercussions and effects on human and wildlife health in the invaded areas.
The focus of this project is to conduct a global horizon scan to help identify alien vertebrate species within the Organisms in Trade Pathway at greatest risk of entering the country, establishing populations, and becoming invasive in the U.S. Our work will address arrival, establishment, and impact via consideration of propagule pressure, climatic similarity to occupied range, and prior invasion history of the focal species and its relatives, respectively.
The approach we are proposing will review a large number (ten of thousands) of Organisms in Trade (OIT) to identify species that that have a high risk of invasiveness in the U.S. By starting with a larger pool of species (opposed to the Roy et al. screening process started with 329 species) there is a great opportunity to recognize new species with no known invasion history. Through a process of filtering the project team will reduce the OIT to a manageable number of higher risk species (~500) based a species potential to arrive, establish, spread, and cause harm (impacts). The project team will also evaluate species with unknown natural histories based on phylogenetic and expert knowledge. We will use a largely automated initial screening, to be followed by expert elicitation and further species prioritization. The development of watch lists can guide early detection efforts, can help inform resource managers, and can provide a repeatable tool for early detection and rapid response efforts (EDRR). In addition, watch list(s) can be used to prioritize evaluations under the injurious Wildlife Provisions of the Lacey Act.”
Dr. Wesley Daniel is a fisheries biologist with the USGS Wetland and Aquatic Research Center’s Nonindigenous Aquatic Species (NAS) Database. He is the coordinator for the NAS Database and curates all the invertebrates and mollusks records. Wes earned his Ph.D. from LSU in Biology, where his research focused on landscape conservation of Gulf Coast Unionidae mussels. After which, he was a post-doctoral researcher with Michigan State University in the Wildlife and Fisheries Program, working with the National Fish Habitat Association to create a nationwide assessment of fish habitat. His current research focuses on developing tools for managers and stakeholders that evaluate the potential spread of non-native and invasive species within and across drainage basins.
Classical Biological Control of Weeds – About Misconceptions and Untapped Opportunities
December 15, 1 p.m. CT
Presented by: Urs Schaffner, PhD
Head Ecosystems Management, CABI
Urs Schaffner is Head of the ‘Ecosystems Management’ section at the CABI Switzerland Centre and affiliate assistant professor at the University of Idaho, USA. His research focuses on soil-plant-herbivore interactions, with particular emphasis on biological invasions, biological control of weeds and grassland restoration. He has 25 years of experience in weed biological control and has worked on aspects such as the ecology and evolutionary ecology of host-specificity of weed biological control agents, pre-release impact assessment, demographic modelling of biological control agents and post-release impact evaluation. Currently he leads a multi-partner project on assessing the environmental and socio-economic effects of invasive trees in Eastern Africa and implementing integrated management strategies, including biological control, that mitigate their negative impacts.
