SRS FIA Survey of Invasive Plants Initiated in 2001 and “phased in” until 2003 States vary in initiation of new cycle 1 -7+ years to complete State while MS is underway and OK not started.

FIA Forest Survey Plots A Sample Plot is randomly positioned within each hexagon Sample Plots contain 4 Subplots each 1/24 acre 1 subplot = 1, 500 acres 2 120 ft between centers 4 . 1 . . 24 ft radius (1/24 acre) 3 . Microplot measurement of seedlings and saplings

We must get ahead in our projections and know what we will be managing. Have working EDRR and containment strategies and programs. Be real about how we tackle these species by long-view assessments that are multispecies. Perform Cost-benefit analyses. Gain political buy-in at all levels.
