Impacts of Invasive Species
Impacts of Invasive Species
Invasive species are dramatically altering Great Lakes aquatic and terrestrial ecosystems, and additional invasives await just outside the region. Environmental managers need to understand both the impacts of current invasive species on the ecosystem and the likely impacts of potential invasives. The GLSC conducts research to explain how invasive species, such as dreissenid mussels, are impacting both ecosystems and the services those ecosystems provide. Some studies seek to clarify risk associated with the introduction of new invasive species, such as Asian carp. Results of this research directly impact invasive species management throughout the basin.

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...
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.
