Habitat loss and transformation are the greatest threats to biodiversity. In the Mediterranean Basin,
planting pines has been a widespread practice that has transformed and degraded natural habitats.
Understanding the response of living organisms to these anthropogenic disturbances and their management
is essential for the conservation of biodiversity. Reforestation in Spain until the end of the 20th century
was conducted primarily with Pinus species at unnaturally high densities. We have analyzed the
response of a reptile community to thinning management in pine plantations within the Sierra Nevada
National Park (SE Spain). Surveyed plots covered a gradient of tree densities (according treatments) from
unlogged plots, 50% logged trees, 66% logged trees, and surrounding areas of open landscape with sparse
trees. Four replicates (plots) were considered per treatment, with 4 visits per plot. In each plot, we measured
three reptile community metrics, species richness, abundance, and Pielou’s evenness. We hypothesize
that reptile metrics will increase with the reduction of pine density and canopy, and an increase of
solar radiation. Our results showed a negligible response after a 50% thinning, but a significant response
of the reptile community after a 66% reduction. This study demonstrates that intense logging in pine
plantations restores reptile diversity in the Mediterranean Basin. This is intended to serve as a model
for forest management to restore biodiversity in this region.
