Areawide vs. Site Specific Areawide vs. Site Specific ApproachApproach Sites viewed in
context with others, not individually
Data can be shared, eliminating redundancy
Co-mingling issues more easily resolved
Variability of scale allows new information to emerge
For ADECFor ADEC Map site locationsMap site locations Determine site status (open, closed, Determine site status (open, closed,
