Resumo
Protected areas have been established historically in
residual places where the potential for extractive uses
is low, implying that places at risk are usually underprotected. Argentina is no exception, with few protected
areas established in productive regions that are prone
to conversion. Here, using reptiles as a study group
and considering the most important human threats in
north-western Argentina, we estimated priority conservation areas where we expect species to persist in the
face of climate change and land conversion. Protected
areas cover no more than 9% of the study region, but
represent less than 15% of reptile distributions. There
are great opportunities for improving the conservation
status in the region by protecting only 8% more of
north-western Argentina, with the level of species
protection inside the protected area network increasing
almost four-fold, reaching 43% of species distributions
on average and 59% of the distributions of threatened
reptiles. Fortunately, the highest diversity of reptiles
in the region does not match the places targeted for
agriculture expansion. Our findings suggest that future
prioritization schemes should embrace other groups
that are especially diverse in the Chaco ecoregion,
which overlaps with our study area
