Potential climate change impacts on native seeds relative to Phragmites

The response of seed germination to future climate change scenarios is an important consideration as climate change will likely exacerbate high mortality rates of seeds and seedlings in the field. Evaluating the response of seed germination under various temperature and water regimes will allow for better predictability in restoration outcomes. Great Salt Lake (GSL) wetlands are a critical resource in the Intermountain West and are globally significant for millions of migratory birds that depend on this habitat. Unfortunately, GSL wetlands are threatened by increasing demands on water upstream for development and agriculture, and the proliferation of invasive species as Phragmites that replaces habitat-forming native plants such as bulrushes. Native bulrushes serve as critical food and nesting sources for migratory birds and are target species for GSL wetland restoration. The study aim was to provide a tool to better predict seed germination of Phragmites and native bulrush species from different regions under current and future climate scenarios. We evaluated seed germination response of Phragmites and three species of native bulrushes to four temperature regimes in growth chambers: 23/10° C (present May), 28/14° C (present June), 33/18° C (present July and also June 2070), and 36/20° C (July 2070), and five water potentials (0, -0.15, -0.3, -0.6, and -1.2 MPa). We compared germination response under these controlled conditions to seeds sown in GSL wetlands, where we monitored seedling emergence during June and July 2018. We found some interesting  interactions of temperature and water potential: (1) under the optimal germination temperature for Phragmites, water potential did not matter, (2) bulrush seed germination varied substantially more among the different temperature regimes than did Phragmites, (3) germination lag time was affected more by the water potential change than by temperature for all species, and (4) field germination rates (range 10 - 24%) were lower than germination under simulated climate change conditions in growth chambers. Our findings can support models to organize, interpret, and forecast wetland restoration outcomes, and also it can improve restoration strategies applied in GSL wetlands. This study was part of the SWS Wetland Ambassador fellowship program during summer 2018.

Dr. Karin Kettenring

Tatiana Lobato de Magalhães' Bio: Agronomist Engineer, with a Master’s degree in Plant Sciences. Tatiana is currently a Ph.D. candidate in Biological Sciences at the Autonomous University of Queretaro, Mexico.  She carried out her SWS Wetland Ambassador fellowship at Utah State University, U.S.A. in 2018, under the mentorship of Dr. Karin Kettenring. The title of her WA project was “Potential climate change impacts on native seeds relative to invasive Phragmites: implications for Great Salt Lake wetland restoration ”.

Her research interests are broad, but they focus on biodiversity, ecology, genetics, and conservation of freshwater ecosystems. She has been working on large-scale spatial patterns of aquatic plants, combining community and population approaches. She has conducted her graduate research mainly on central Mexico highland sites, where temporary wetlands are part of the landscape and are geographically isolated.

Dr. Karin Kettenring's Bio: Karin is an Associate Professor in the Department of Watershed Sciences at Utah State University and the head of the Wetland Ecology Lab.  

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. Her Ph.D. research focused on restoration of sedges in prairie pothole wetlands. She was also a Postdoctoral Fellow with Dr. Dennis Whigham at Smithsonian Environmental Research Center where she studied the invasion of Phragmites australis in Chesapeake Bay tidal wetlands. She has been a faculty member at USU since 2008.

Her current research efforts focus on (1) the ecology, genetics, and management of wetland invaders, (2) seed ecology of native wetlands plants, with implications for wetland revegetation, and (3) restoration genetics for sustainable, functioning wetland restorations.

The State of Vermont strives to provide and apply the best mapping tools available to protect and restore wetlands throughout the State. Through the Agency of Natural Resource’s Wetlands Inventory Map the State is able to consolidate and provide these layers to their partners and general public. The base of many of these tools is the jurisdictional layer, the Vermont Significant Wetland Inventory (VSWI), that protects wetlands via GIS mapping derived from the NWI dataset. A supplement to the VSWI is the ever-evolving Wetlands Advisory Layer which is continuously amended with non-jurisdictional mapping data derived from regulatory and non-regulatory boots on the ground work; including NWI+ updates, EPA funded bioassessment monitoring, Natural Heritage cataloguing, Program staff site visits, and other governmental and non-governmental wetland mapping projects. The most recent update to this layer will include an NWI layer update for the Missisquoi River to meet NWI+/LLWW standards. This watershed was targeted for revision since it was understood to be under mapped and due to its diverse landscape and mixed land use history.

Along with these mapping layers, Vermont also has a wetland restoration site prioritization model and associated mapping product to target restoration efforts towards meeting our Lake Champlain phosphorus TMDL goals. The original GIS-based Lake Champlain Wetland Restoration Plan is a quantitative prioritization model to rank the potential of land to mitigate P loading to Lake Champlain based on site function and upslope drainage attributes. A recent model update further refined the original output and resulted in the development of potential wetland restoration easement boundaries for targeted landowner outreach.

Brock Freyer


Brock Freyer's Bio

Brock Freyer currently works to protect Vermont’s wetlands as a District Wetlands Ecologist in Vermont Department of Environmental Conservation’s Wetlands Program. In doing so he collaborates with state, federal and non-government organizations by providing regulatory, technical, and moral support. Prior to his work in Vermont, he has bounced around the U.S. wandering in wetland and riverine systems hoping to keep his feet dry in wet spots. No matter where he is working, he is constantly intrigued by the working landscape and how our activities have altered the natural systems present. Through a hydrogeomorphic/landscape scale lens he looks for opportunities to restore and enhance these potentially degraded systems. Brock is a PWS (#2441), has a M.S. degree in Earth Sciences from UNC-Charlotte, and a B.S. in Natural Resource Management from Western Carolina University.
