Tier 2 - Assess As Needed
The size and extent of these species populations are currently being inventoried with limited geographic information available. This survey will assist with identifying future control targets as populations are defined.
Action: The inventory of these plants is ongoing. The approximate number of plants should be recorded keeping in mind population sizes may be highly variable.
