Debate about the conservation value of secondary habitats has tended to
focus on tropical forests, increasingly recognizing the role of secondary
forests for biodiversity conservation. However, there remains a lack of
information about the conservation value of secondary savannas. Here, we
conducted a camera trap survey to assess the effect of secondary
vegetation on large mammals in a Brazilian Cerrado protected area, using a
single-season occupancy framework to investigate the response of
individual species (species-level models) and of all species combined
(community-level models). In addition, we investigated the cost
effectiveness of different sampling designs to monitor globally threatened
species in the study area. At the community level, savanna that
regenerated from eucalyptus plantation had similar occupancy estimate as
old growth areas. At the species level, none of the ten species
individually assessed seemed to respond to succession stage, with greater
support for the effect of other covariates on occupancy, such as distance
from water and vegetation physiognomy. These results demonstrate that
secondary vegetation does not appear to negatively impact large mammals in
the study area and suggest that, given a favorable context, Cerrado
mammals can recolonize and use secondary savannas that regenerated from
clearcut. However, our study area should be considered a best-case
scenario, as it retained key ecological attributes of high-value secondary
habitats. Our simulations showed that a sampling design with 60 camera
trap sites surveyed during nine occasions is appropriate to monitor most
globally threatened species in the study area, and could be a useful
starting point for new monitoring initiatives in other Cerrado areas.
