Description
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).
Data Records
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 206 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

| Funding | This research was supported by the DRCT scholarship M3.1.a/F/135/2015, from the Azores Government, and by FEDER in 85% and by Azorean Public funds by 15% through Operational Program Azores 2020, under the project AZORESBIOPORTAL –PORBIOTA (ACORES-01-0145-FEDER-000072). |
| Study Area Description | Terceira Island (area: 400.6 km²; elevation: 1,021.14 m) and São Miguel Island (area: 744.6 km²; elevation: 1,103 m) are two of the nine islands from the Azores archipelago. The climate in the Azores is temperate oceanic, with regular and abundant rainfall, with high levels of relative humidity and persistent winds, mainly during the winter and autumn seasons. Terceira Island is known for the presence of some very important pristine areas at high elevation (Gaspar et al. 2011). However, few natural areas still remain at lower elevations, notably in Praia da Vitória’s council. |
| Design Description | At all plots we applied the optimised and standardised COBRA (Conservation Oriented Biodiversity Rapid Assessment) sampling protocol for temperate forests (Cardoso 2009). Different variants of the COBRA protocol for spiders have already been applied in oceanic islands (Emerson et al. 2017) and tropical forests (Malumbres-Olarte et al. 2019, Malumbres-Olarte et al. 2020). Although originally developed and optimised for mainland habitats, COBRA has been recently proposed to be the standard protocol for inventorying and monitoring island forest ecosystems (Borges et al. 2018). |

Sampling Methods
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).
| 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. |
|---|---|
| Quality Control | Sampling was performed with the standardized COBRA protocol, and all species were identified by a taxonomist. |
Method step description:
- 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.
