Summary: | Abstract
The current study attempts to explore the diversity patterns and the
ecological structure of herpetofauna in order to provide a guideline for its
conservation management, taking as case study the Dadia national park, in
Greece. We surveyed 36 sites by conducting time constraint visits and random
transects to sample semi-aquatic (amphibians and freshwater terrapins) and
terrestrial (lizards and terrestrial tortoises) herpetofauna respectively.
We recorded 20 herpetofauna taxa, including five protected species. The park
authorities should maintain brooks as a high priority habitat for
semi-aquatic herpetofauna, periodically flooded land and lowland streams as
important habitats, and to a lesser degree anthropogenic wet habitats.
Semi-aquatic species have narrow habitat requirements related to substrate
type and humidity. Terrestrial herpetofauna species are influenced by the
degree of shade and the type of substrate; they favour a diversity of
semi-open habitats (open oakwoods, heaths), located in the buffer zone
rather than in the core of the park that contains densely forested habitats.
Management focusing on raptors, the initial conservation priority of the
national park, is compatible with the conservation of the terrestrial
herpetofauna, as the proposed maintenance of an open forest structure is
beneficial for terrestrial herpetofauna as well. Our research indicates that
future management programs will have to address the needs of herpetofauna
species independently and that they should also be integrated in the
monitoring programme of the park, with emphasis on the conservation status
and trend of the five protected species. |
