Conservation Planning Components
Importance: the extent to which locations on the landscape are replaceable with respect to achieving the conservation goals we have specified.
Vulnerabilility: extent and threat of conversion/transformation both now and in the future.

KEY PATTERNS large areas that still retain characteristics
of “wild” landscapes and that have not yet experienced permanent transformation to settlement,
large areas of permanent transformation that threaten and increasingly fragment the “wild” landscapes,
an increase in transformation in most locations under most future scenarios, and
areas of high irreplaceability and vulnerability across the region that are not currently protected or targeted for protection.

TAKE-HOME MESSAGES Identifies the most urgent priorities in the form
of conservation triage. Identifies sites that are most likely to increase
in vulnerability status, many of which lie within zones of connectivity between important relatively intact areas.
The selection of the planning unit has great bearing on the ultimate results in priority ranking, and must therefore be chosen carefully.
Individual layers that collectively contribute to assessments of irreplaceability and vulnerability should not disappear from view, and will be equally valuable to planners characterizing the landscape in question.
