Survey of Forest Exotic Pest Plants Data
Collected in Forested Subplots
VAST OPPORTUNITIES FOR CORRELATIVE AND
MODELLING RESEARCH

• Landscape Context
• Geographic Coordinates
• Elevation
• Proximity to Ag, Roads,
• Urban, Water
• Size of forest fragment
• Non-forest edge conditions

• Subplot/Condition
• Slope, Aspect, Physiography
• Disturbances
• Timber Treatments
• Ownership, Land Use
• Forest Type, Stand Age
• Prior land use

• All Trees gt4 in dbh Measured and Assessed
• Location in Subplot
• Species, Diameter, Height, Status, Damage, etc

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 multi-species. Perform
Cost-benefit analyses. Gain political buy-in at
all levels.
