New York State Invasive Species Tiers


Overview

These invasive species tiers guide management priorities in each PRISM and across New York State.

To generate tiers for hundreds of invasive species, we devised a new method that combines data from iMapInvasives with invasiveness assessments and expert feedback.

Use the filters below to generate tier lists for your region and use the search box to find a specific species. In the table, click on the common name to see its distribution in iMapInvasives.

    Species Tier Definitions

  • Tier 1: Highly invasive species located in a buffer around region but not in region itself, being monitored
    • Tier 1a: Tier 1 species located in a 100 mile buffer around the region
    • Tier 1b: Tier 1 species located in Eastern North America, but not in 100 mile buffer
    • Tier 1c: Tier 1 species with an introduction pathway, but outside Eastern North America
  • Tier 2: Highly invasive species with low abundance in the region, management goal of eradication
  • Tier 3: Highly invasive species with medium abundance in the region, management goal of containment
  • Tier 4: Highly invasive species with great abundance in the region, management goal of local control
  • Tier 5: Non-native species in the region with unknown invasiveness, requiring research or monitoring
  • Untiered: Non-native species located in the region (not suitable for management, not yet evaluated, or additional data may be needed)
  • Buffer: Non-native species located in 100 mile buffer (not yet tiered)
  • (Blank): Species located neither in region nor in buffer
