[APWG] Terminology still unresolved? Re: Jewelweed

Dear All:
I like "Ecosystem Restoration" Group, terminology which has been used on
this list by others, or "habitat remediation" or anything that keeps the
focus on the whole picture instead of seeing "invasive plants" as the cause
of habitat destruction, when they are usually just a symptom. Also, not all
exotics are causing problems in the ecosystem, and some are powerful
bioremediators.
Similarly, the terminology used is just a symptom, not the cause of how we
are conceptualizing environmental changes. But discussing the terminology,
I agree, is probably key to concept shifting.
