ST. LAWRENCE EASTERN LAKE ONTARIO PARTNERSHIP FOR REGIONAL INVASIVE SPECIES MANAGEMENT

Chaumont Barrens

About This Priority Conservation Area

Located in Chaumont, NY, is Chaumont Barrens, one of the finest examples of an Alvar grassland in the world (NYSDEC).  Alvars are characterized by shallow soils and rocky terrain. In these conditions, only plants that are highly adaptable to flooding, drought, and extreme temperatures survive. Prairie smoke, Geum triflorum, grows in Chaumont Barrens and is found nowhere else in the northeast.

Tier List Species Recorded at This PCA

These 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 categorized in each tier are dependent on species distribution, abundance, and management options available, and may vary depending on the region. The species listed below are the species categorized in the SLELO PRISM region.

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 were found at this PCA at this time. 

Tier 2 Species

Eradication

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 were 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
  • Oriental bittersweet
  • Pale swallow-wort

Tier 4 Species

Suppression/Local Control

The management approach is containment/exclusion. 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
  • Common buckthorn
  • Honeysuckle spp.

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 were found at this PCA at this time. 

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

  • Common barberry 
  • Garlic mustard
  • Tufted vetch
