SLELO PRISM

Tiered Species List

This tiered species list categorizes species by population distribution within the SLELO region and feasible management approaches: prevention, eradication, suppression localized control, and monitoring.


Tier 1 Species (Prevention)

Species are not known to be present within the region but are within a 100 mile radius or a pathway exists. 


Tier 2 Species (Eradication)

Species are present in the region, but at low abundance. Eradication feasible within Priority Conservation Areas.


Tier 3 Species (Suppression )

Species are considered to be too widespread for eradication although, some areas remain unaffected. Infestations found within Priority Conservation Areas (PCA’s) are targeted


Tier 4 Species (Localized Control)

Species are considered too widespread to eradicate. High priority resources, like rare plant or recreation assets, are protected through localized management strategies.


Tier 5 Species (Monitor)

Species that may or may not be in PRISM but are difficult to respond to or that require more knowledge of.
