Monitoring Design
• Annual Inventory
– New Features Every Year
– Points, Lines & Polygons
– Aerial Photo Interpretation
– Spatial Grid
• Annual Sampling
– Permanent Plots
Spatial Data Collection Equipment
• Handheld GPS units
• ArcPad or TerraSync
Software
• Rubber Boots
• Bicycles
• Kayaks
• Power boats
• Airplane or
• Helicopter!
Spatial Data Collection Methods
• Customized data dictionaries
• Points, lines & polygons
• Grid cells
The Past
•

•
•
Extended tidal range
Longer, wider leaves
Longer, fatter inflorescences
This is
Taller
easy!

Map Production
• Interactive map (used in house…a LOT)
• Field maps (to inform monitoring)
• Reporting maps (to share with partners,
others)
Decision Support
• Maps
• Lab results
• Summary data

Not so easy
anymore, huh?
The Present
• All obvious plants sprayed 2+ years
• Regrowth stunted by herbicide
• Regrowth may not flower
Is this
hybrid
regrowth,
or native?

Monitoring Program
Short-Term Future
• Expand Patch-level Treatment Surveys
• Genetic Test Refinement
• Continued Focus on GPS/GIS
Information for Control Program Success
The Future
• Use GPS to guide treatment
• Record patch-level treatment effort
