This table provides presence/absence (binary occurrence) data for adult ground beetles (Coleoptera: Carabidae) at the 768 sampling points of the HIGH-PBS dataset, across 29 high-elevation sites in the Italian Alps and Apennines (1,875–3,120 m a.s.l.), surveyed between 2010 and 2023. The data were derived from the activity density records obtained by pitfall trapping (see beetle_abundance.tab in the same submission for full methodology): each species column contains a binary value, with 1 = at least one adult individual recorded at that sampling point and 0 = species not recorded. The table is provided alongside the activity density version to offer a conservative, directly comparable occurrence measure that accommodates analytical approaches (e.g. occupancy models, beta-diversity metrics, community composition analyses) for which quantitative capture rates are not required or not appropriate. It also allows users to include sites where only presence/absence data could be derived. The table covers 71 Carabidae species identified to species level; nomenclature follows the checklist of the Italian Carabid Beetles fauna. Each row is identified by three columns: Event label (unique sampling point identifier, primary key shared with the other five tables of the dataset), Code Landform (CS, DG, F1, F2, RGa, RGr, SF, SS) and Code Area (29 site codes). Voucher specimens are preserved in ca. 70% ethanol at the MUSE - Science Museum of Trento (Italy).

Ground beetle (Carabidae) presence/absence data per pitfall trap, containing Event label: sampling point identifier (Code: Multiple naming conventions are used, reflecting different sampling campaigns: format 1 (395 points): Site.Landform.Plot.Point (e.g., Agl.CS.1.a); format 2 (275 points): SITE##X (e.g., AGO32B, CLA31A, PEI12A); format 3 (30 points): SITE##.X (e.g., LAZ01.A); format 4 (24 points): U##.X (e.g., U05.A) — Val d'Ultimo site; format 5 (other): site-specific codes (e.g., FRA-FRO11A, SORC3.1A); two labels end in .vista (visual surveys on previously sampled plots), Latitude, longitude, elevation, location of sampling event, * Code Area: site code, * Code Landform: landform type, * Year of sampling, * Species columns (71 species) as presence/absence: binary values (1 = species present, 0 = species absent at that sampling point).
