Insect and spider biodiversity: A dataset of mountainous wetland sites in Aspromonte National Park (Calabria, southern Italy)

Wetland areas encompass a range of natural habitats characterized by high animal and plant biodiversity. Understanding the impacts of environmental decline in such areas requires in-depth knowledge of the overall biodiversity. This study dataset provides a first evaluation of important sites of insect and arachnids biodiversity in peat bogs, marshes, and streams in Aspromonte National Park in Calabria, southern Italy. It is a basic faunal survey that aids understanding of the importance of these large faunal groups in sites mainly within this national park. The data obtained highlight a rich insect and spider diversity in this region and provide useful information to use to outline strategies for the conservation and the management of inland aquatic environments at risk from climate change. Moreover, as baseline data, these will be useful for future monitoring and management of other inland aquatic environments that are similar to those of the study sites reported herein.
