Biodiversity is not completely known anywhere, so conservation
planning is always based on surrogates for which data are available
and, hence, assumed effective for the conservation of unknown biodiversity.
We review the literature on the effectiveness of surrogates
for conservation planning based on complementary representation.
We apply a standardized approach based on a Species Accumulation
Index of surrogate effectiveness to compare results from 575 tests
in 27 studies. Overall, we find positive, but relatively weak, surrogacy
power. Cross-taxon surrogates are substantially more effective
than surrogates based on environmental data. Within cross-taxon
tests, surrogacy was higher for tests within the same realm (terrestrial,
marine, freshwater). Surrogacy was higher when extrapolated
(rather than field) data were used. Our results suggest that practical
conservation planning based on data for well-known taxonomic
groups can cautiously proceed under the assumption that it captures
species in less well-known taxa, at least within the same realm.
