In order to conserve or restore native imperiled species, natural resource managers must understand the biology, or internal workings, of these species. This helps them identify strategies for or impediments to restoration or conservation efforts. Scientists at the GLSC focus extensive research on the native lake trout, including trends of insufficient nutrition (vitamin B) in reproduction, the function of pheromones, the use of energy, and the effects of catch-and-release deep-water angling practices. The GLSC also studies the morphology of native coregonid prey fish species, generating tools for scientists and fishery managers.

Long-term Monitoring of Great Lakes Coastal Wetlands and Contributions to the Coastal Wetland Monitoring Program
The Coastal Wetland Monitoring Program (CWMP) is an EPA-led program to monitor the health of all Great Lakes coastal wetlands larger than four hectares. USGS scientists are working with Principal Investigators from many State and academic institutions to conduct data collection, implement standardized sampling protocols, analyze multiparameter data, and communicate results to the public.
Invasive Phragmites Science: Using Microbial Interactions to Foster the Restoration of Great Lakes Wetlands
The USGS is developing innovative Phragmites control measures to keep this rapidly spreading invasive plant from further expanding its range into new wetland habitats and to aid in the development of successful restoration strategies. Scientists are conducting studies and field tests to determine (1) if microbes (i.e., fungi and bacteria) that live within and around Phragmites are enabling the...
Restoring Wetland Habitat and Function at the Shiawassee National Wildlife Refuge
Hydrologic connectivity is essential to maintaining coastal wetland services and functionality. Impounded wetlands often do not provide essential services such as flood mitigation and nutrient retention, nor can they be utilized as spawning and nursery habitat by important Great Lakes fishes. The Shiawassee National Wildlife Refuge manages hundreds of acres of historical coastal wetland habitat...
Great Lakes Coastal Wetland Ecology, Restoration, and Decision-Support Tools
USGS scientists developed the Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) decision support tool to help resource managers prioritize where to invest in restoration activities. The Functional Assessment analysis tool helps managers quantify changes in ecosystem services associated with restoration actions.
Using Pollinator Environmental DNA to Assess the Ecological Resilience of America’s Grasslands
Scientists from six USGS science centers are collaborating with USDA, university, and Tribal partners, and Department of the Interior land managers, to assess the status of pollinator communities and the distribution of species of conservation concern using environmental DNA. These methods will be used to improve assessments of habitat quality and pollinator responses to restoration, including...

Phragmites Adaptive Management Framework – Active Adaptive Management
Non-native Phragmites australis (Common Reed) has become established across the Great Lakes basin, outcompeting native plants and degrading natural habitats. Phragmites is managed using a variety of resource-intensive techniques, yet effectiveness of treatment may vary due to infestation level, application methods, environmental conditions, or other factors. With the goal to reduce uncertainty in...
Innovative Approaches for Wetland Restoration and Invasive Species Management
Coastal and wetland ecosystems provide critical habitat to birds, fish, wildlife, and a suite of other organisms, clean our water and mitigate flooding events, and offer tremendous recreational opportunities to visitors. However, the majority of coastal and wetland ecosystems in the Great Lakes basin have been significantly degraded or destroyed by ditching, draining, development, invasive species...
Invasive Phragmites Science: Great Lakes Phragmites Collaborative and the Phragmites Adaptive Management Framework
Broad coordination is required to overcome large-scale regional challenges such as controlling a persistent invasive plant like Phragmites . Individual management actions may have local impact, but their implementation can be inefficient and landscape-scale impacts are limited. The highly successful Great Lakes Phragmites Collaborative builds collaboration and facilitates communication on a...
Effects of Great Lakes water levels on coastal populations of Phragmites australis GeoNarrative
The "Phragmites Management and Variable Great Lakes Water Levels" GeoNarrative presents research by the US Geological Survey and US Fish and Wildlife Service on how Great Lakes water levels affect expansion and management of coastal Phragmites populations.
Invasive Phragmites Science: Management Tools for the Control of Invasive Phragmites to Foster the Restoration of the Great Lakes
The USGS is developing innovative Phragmites control measures to keep this rapidly spreading invasive plant from further expanding its range into new wetland habitats and to aid in the development of successful restoration strategies. Scientists are conducting studies and field tests to determine (1) if microbes (i.e., fungi and bacteria) that live within and around Phragmites are enabling the...
