SLELO PRISM

Upper and Lower Lakes WMA

2019_ULLWMA_Brogers-98

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 water control 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.

Tier List Species Recorded at This PCA

The invasive species tiers guide management priorities in New York State and are utilized by the Partnership for Regional Invasive Species Management or PRISM network. The species in each tier are categorized by their distribution, abundance, and available management options, and may vary depending on the region. The species listed below are the species categorized in the SLELO PRISM region. View a full list of tiered species in the SLELO PRISM.  Learn about New York State Invasive Species Tiers and view a Story-Map

Tier 1 Species

Early Detection/Prevention 

The management approach is early detection & prevention. Species are not known to be in the SLELO region but are within 100 miles and an introduction pathway exists. 

Species Recorded at This PCA

No tier 1 species are found at this PCA at this time. 

Tier 2 Species

Eradication

The management approach is eradication. Species are known to be present in the SLELO region but are in low abundance with suitable treatment methods available to make eradication feasible with Priority Conservation Areas. 

Species Recorded at This PCA

No tier 2 species are found at this PCA at this time. 

Tier 3 Species

Containment/Exclusion

The management approach is containment/exclusion. Species are too widespread for eradication from the region, but some areas remain unaffected. Targeted management can be used to suppress the population within Priority Conservation Areas. 

Species Recorded at This PCA
  • Common buckthorn
  • Common reed grass
  • Japanese knotweed
  • Pale swallow-wort

Tier 4 Species

Suppression/Local Control

The management approach is suppression/local control. Species are present and widespread throughout the region with no chance of eradication. Localized management is applied to protect high-priority resources like rare plant habitats or recreation areas. 

Species Recorded at This PCA
  • Eurasian water-milfoil
  • European frog-bit
  • Honeysuckle spp. 
  • Purple loosestrife
  • Wild Parsnip                     

Tier 5 Species

Monitor

The management approach is to monitor. Species may or may not be in the region but are difficult to respond to or require more knowledge of distribution, and management options. 

Species Recorded at This PCA

No tier 5 species are found at this PCA at this time. 

Species Recorded at this PCA that are not listed in SLELO PRISM's Tiers
