Mowing Cattail Cover To Increase Aquatic Vegetation Diversity On The Coeur D’Alene River Floodplain In Cataldo, Idaho, Makenna J. Tabino

2023 Symposium

The Schlepp Easement is a 400 acre wetland on the Coeur D’Alene River floodplain, near Cataldo, Idaho. The wetland has been restored to protect it from heavy metal pollution transported downstream from mining sites near Kellogg, Idaho, the location of the Bunker Hill EPA Superfund Site. This wetland was restored to provide safe habitats and feeding grounds for migratory waterfowl and to maintain wetland biodiversity. However, cattail is prone to becoming overdominant and outcompeting other plants, which greatly limits a wetland’s biodiversity. Our objectives were to test whether aquatic boat mowing can reduce cattail cover, improving species diversity and cover …

Soil Salinity And The Occurrence Of Invasive Phragmites Australis In Scarborough Marsh, Anthony Devecchis

Thinking Matters Symposium

In North America, Phragmites australis (Cav.) Trin. is a common invasive reed that competes well in wetland ecosystems and wet ditches. According to the Maine Department of Agriculture, Conservation and Forestry’s Natural Areas Program, P. australis is disruptive to both tidal and freshwater marshes throughout Maine, including Scarborough Marsh, the state’s largest salt marsh covering an area of 3100 acres (≈ 1,254 hectares). Like many tidal marshes, Scarborough Marsh plays an important role buffering against high tides and flood waters, whilst providing key habitat for numerous species of fishes, birds, and insects. Previous research suggests that changes in soil …

Impact Analysis On The Invasive Oriental Weather Loach (Misgurnus Anguillicaudatus) In The Grant Creek And Prairie Creek Watersheds At Midewin National Tallgrass Prairie, Adam Vanhaitsma

Scholar Week 2016 - present

Presentation Location: Weber Center, Room 101

Abstract

In 2014, the invasive Oriental weather loach was found in the Prairie Creek wetland at Midewin National Tallgrass Prairie. While little is known about the Oriental weather loach and its impact on freshwater ecosystems it has become a widespread invasive species. Being the first to investigate the impact of the Oriental weather loach on the Grant Creek and Prairie Creek watersheds at Midewin National Tallgrass Prairie, we set traps for specimens from early June till late July in both watersheds. Each loach that was caught was euthanized and dissected in order to understand …

Application Of Genomics To Develop A Monitoring Tool For Stormwater Treatment Wetlands, Jessica Lenoble, Chris Johnston, James Atwater, Susan Baldwin

Salish Sea Ecosystem Conference

Urban stormwater treatment wetlands benefit communities because they filter pollutants from receiving waters and provide habitat for urban wildlife and birds. The installation of wetlands is often avoided because stormwater quality is highly variable, which makes it both challenging and expensive to ensure that the wetlands are effectively mitigating the impacts of stormwater runoff. For decades, macroscopic species, such as benthic invertebrates, have been used as biological indicators of watershed health. With recent advancements in genomics (the branch of science that studies the function and structure of DNA within a single cell), it may now be feasible to use microscopic …

Using Traditional Ecological Knowledge To Protect Wetlands: The Swinomish Tribe's Wetlands Cultural Assessment Project, Todd Mitchell, Nicole J. Casper

Salish Sea Ecosystem Conference

“Traditional” wetland physical assessment modules do not adequately identify Tribal cultural values of wetlands and thus wetlands may not be adequately protected for cultural uses. This Swinomish Wetlands Cultural Assessment Project has developed a cultural resource scoring module that can be incorporated into wetland assessments to better inform wetland protections. Local native knowledge was gathered about the traditional uses of 99 native wetland plant species. A cultural scoring matrix was developed based on the presence of traditionally used plants in several use categories including: construction, ceremonial, subsistence, medicinal, common use, plant rarity, and place of value for each wetland. The …
