The data presented here comes from samples collected as part of one recent doctoral project, which aimed to assess several components of the ecological impacts of recreational tourism on spiders. We focused on the Azorean forests, due to being home to several endemic species and its high interest in conservation. We applied the sampling protocol COBRA (Conservation Oriented Biodiversity Rapid Assessment, Cardoso 2009) in twenty-three 50 m x 50 m native forest plots in the Terceira and São Miguel Islands to assess the diversity of spiders species. Through this publication we contribute to the knowledge of the arachnofauna in the recreational trails of native forests of the Azores. Of the 45 species collected, were 13 endemic (9689 specimens), 10 native non-endemic (2048 specimens), and 22 introduced (698 specimens).Sampling Description
Study Extent
We selected twenty-three 50x50m sampling sites in native forest patches along the studied trails, at increasing distances from the trail head: 0m, 50m and 250m. Another sampling site was added along the trail in the area with the most pristine surrounding forest (Max). Finally, two control sites were placed inside the forest, at 50m and approximately 250m from the closest trail point. Therefore, whenever there were the conditions for it, the trails had six sampling sites. The design allowed to understand whether there were ecological differences at different distances from the trail head.Sampling
The COBRA protocols have been proposed as part of standard inventorying and monitoring programs on island and continental ecosystems, and have already been used for a number of studies on spiders and beetles (Cardoso 2009, Borges et al. 2018, Malumbres-Olarte et al. 2019, Malumbres-Olarte et al. 2020).Quality Control
Sampling was performed with the standardized COBRA protocol, and all species were identified by a taxonomist.Method steps
- The data has been published as a Darwin Core Archive (DwC-A), which is a standardised format for sharing biodiversity data as a set of one or more data tables. The core data table contains 194 records (eventID). One extension data table also exists with 1290 occurrences. The extension supplies extra information about the core record.
Taxonomic Coverages
All Araneae were identified at species level.
