Gap Analysis.

A gap analysis is a traditional planning evaluation based on the assessment of existing or proposed protected-area networks. The analysis identifies critical gaps in coverage (Scott et al. 1993) in order to highlight biodiversity that may not be conserved without additional targeted conservation effort.

Take these Brazilian species features for example.

A gap analysis gives us useful quantitative information about how much of our species features are already within conservation areas.
