EDDMapS’ primary goal is to discover the existing range and leading edge of invasive species while documenting vital information about the species and habitat using standardized data collection protocols. EDDMapS allows for data from many organizations and groups to be combined into one database to show a better map of the range of an invasive species.  Goals of the current project include: integration of existing regional datasets, increase search options on EDDMapS website, update NAISMA Invasive Species Mapping Standards, and coordinate with local, state and regional organizations to develop early detection networks.  After twelve years of development of EDDMapS, it has become clear that these local organizations are key to developing a successful early detection and rapid response network.  The University of Georgia Center for Invasive Species and Ecosystem Health has released 15 apps to support data entry into EDDMapS.

The Nonindigenous Aquatic Species Database first began in the early 1990s with the passage of legislation related to zebra mussels. Since that time, the group has tracked the distribution of non-native aquatic species nationwide. At present, we focus primarily on freshwater species in the continental US and island territories. The system primarily tracks fish, crustaceans, mollusks, reptiles and amphibians, and obligate aquatic plants. The Program’s interactive website allows users to perform a variety of queries, download data, obtain information from species profiles, and see animations of species’ spread. There is an alert system connected to the database. Registered users receive email alerts when a species of interest is found in a new area. Other components recently added include NAS FaST – the Flood and Storm Tracker which can be used to predict where species may have moved into new drainages based on flooding. The NAS ARM, alert risk mapper, will show the extent of possible initial dispersal based on biology and barriers.

Phragmites australis: Current Research and Experiments in Control Strategies for Wetland Habitat Recovery

Wednesday - February 21, 2018 - 3pm EST 


Marla Stelk, Policy Analyst, Association of State Wetland Managers [POWERPOINT PRESENTATION]



Dr. Karin Kettenring and Christine Rohal

Phragmites australis has aggressively invaded wetlands in northern Utah including wetlands along the iconic Great Salt Lake.  Since 2010, Utah State University researchers and wetlands managers have partnered to improves Phragmites management techniques and outcomes.  In this talk we will discuss (1) how a formal manager survey informed a Phragmites management research experiment, and (2) how these Phragmites management experiments yielded important insights into how best to control Phragmites and the potential for habitat recovery.

Dr. Andrea Dávalos

Land manager organizations spend significant resources controlling invasive plants, yet there is surprisingly little evidence to assess success of invasive plant management.  The rapid range expansions of invasive Phragmites australis in North America have prompted large-scale control efforts, although with limited success.  Assessment of P. australis management in the Adirondack Park, New York State shows that eradication, through herbicide application, is only achievable for the smallest populations. Long-term control of the invasion will require continuous use of herbicides, not only jeopardizing native wetland biota but also threatening existence of the endemic subspecies P. australis americanus.  Alternatively, biological control is a promising and safer tool.  Two European stem mining noctuids show very strong, but not absolute, preference for invasive P. australis.  Demographic techniques are being implemented to improve host-specificity assessment and evaluate management success.  Invasive species management should go beyond short-term suppression of target plants and should incorporate quantitative measurements of outcomes.


Dr. Karin Kettenring is a faculty member in the Department of Watershed Sciences, Quinney College of Natural Resources, Utah State University in Logan, Utah.  She has a B.A. in biology from Oberlin College. She received her Ph.D. in applied plant sciences from the University of Minnesota where she worked with Dr. Susan Galatowitsch.

Beyond weed control: Establishing ecosystem goals, objectives, and desired outcomes for degraded coastal wetlands

Invasive plant removal is usually an integral part of coastal wetland restoration projects, sometimes at a relatively high cost. While there is acceptance of the biodiversity loss associated with invasive plants such as reed (Phragmites australis) and narrow-leaved cattail (Typha angustifolia and T. x glauca), managers are ultimately responsible for considering trade-offs of various intervention strategies. This talk describes the importance of establishing ecosystem goals and objectives to achieve specific conservation outcomes before invasive species control efforts begin so that decisions about trade-offs become easier. Examples from western Lake Erie will reveal a wide range of desired outcomes because of various local constraints such as the nature of the surrounding landscape. Desired conservation outcomes are more likely to be achieved if there is clear linkage between invasive species removal and the stated project goals and objectives. Removal of invasive species always involves difficult trade-offs; however, practitioners frequently monitor acres treated instead of the overall impacts of control projects in achieving their conservation goals.

Monitoring multiple biological attributes in the Great Lakes coastal wetlands: database access for invasive species management

Since European settlement, over 50% of Laurentian Great Lakes coastal wetlands have been lost, causing growing concern by government agencies. To facilitate information sharing between public, private, and government agencies throughout the basin, we developed standardized methods and indicators used for assessing wetland condition. Using an ecosystem approach, birds, anurans, fish, macroinvertebrates, vegetation, and physicochemical conditions were sampled in coastal wetlands of all five Great Lakes, US and Canada. Our primary objective was to implement a standardized basin-wide monitoring program that would be a powerful tool to inform coastal wetland conservation and restoration priorities throughout the basin.

Creating and empowering cooperative invasive species management areas across Michigan with multi-scaled support networks.

The challenges associated with Invasive Species Management span geo-political boundaries, property ownership boundaries, and even human values. In order to overcome these challenges, it can be beneficial to view individual invasive species problems as part of a much bigger picture. Regional Cooperative Invasive Species efforts are a practical implementation of this “big picture” mindset. This presentation will cover recent efforts to create and empower Cooperative Invasive Species Management Areas across all of Michigan. It will also cover several networks that continue to provide critical support and value to these groups at local, state, and basin-wide scales.
