Upper Lower Lakes Wildlife Management Area


About this Priority Conservation Area

The Upper Lower Lakes Wildlife Management Area is located near Canton, St. Lawrence County in NYS. This large developed wetland complex is found between the Grass River and the Oswegatchie River and consists of open waters, wet meadows, emergent marsh, shrub swamp and wooded wetlands. This region provides important habitat for marshbirds and waterfowl (i.e., the Common Loon). The large open water lake is controlled by a watercontrol structure at the western end of the WMA, contributing to it being a viable nesting area. The Indian Creek Nature Center is found on the north-western boundary, which contains ~320 acres of woods and wetland within the WMA. For more information on this WMA, please visit our partners at NYSDEC

Prevent the introduction of invasive species into the SLELO PRISM.

Rapidly detect new and recent invaders and eliminate all individuals within a specific area.

Share resources, including funding personnel, equipment, information, and expertise.

Collect, utilize, and share information regarding surveys, infestations, control methods, monitoring, and research.

Control invasive species infestations by using best management practices, methods and techniques to include: ERADICATION (which is to eliminate all individuals and the seed bank from an area), CONTAINMENT (which is reducing the spread of established infestations from entering an uninfested area) and SUPPRESSION which is to reduce the density but not necessarily the total infested area.

Develop and implement effective restoration methods for areas that have been degraded by invasive species and where suppression or control has taken place.

Increase public awareness and understanding of invasive species.

Develop and implement innovative technologies that help us to better understand, visualize, alleviate or manage invasive species and their impacts or that serve to strengthen ecosystem function and/or processes.
