Conducted between March 2019 and December 2020, the study identified and georeferenced 31 sites—livestock troughs, ponds, and small artificial basins—distributed between 537 and 1117 m a.s.l. Each water point was described through structural and functional parameters and surveyed for associated aquatic fauna. Thirteen species of Odonata, one of Reptilia and five of Amphibia were recorded, including the Italian Crested Newt (Triturus carnifex) and the Common Toad (Bufo bufo), both indicators of good habitat quality. The results confirm the ecological significance of these minor lentic systems as biodiversity refuges in a karstic landscape with scarce surface waters. The dataset provides a geospatial and ecological baseline for conservation actions and future inventories of small aquatic habitats in the Lazio region.

The area extends in a northwest–southeast direction between the Simbruini Mountains to the northeast, the Arcinazzo Plateau to the south, and the Ruffi Mountains to the west. It includes the municipalities of Arcinazzo Romano, Trevi nel Lazio and Affile. 13.089139 13.277778 41.891083 41.814389 537 1117 meter 2019-03-03 2020-12-20 Species Aeshna cyanea 65BN5 Species Anax imperator DJX8 Species Bufo bufo NP2D Species Coenagrion puella WTXY Species Crocothemis erythraea ZKQD Species Enallagma cyathigerum 39M5B Species Hyla intermedia 3NCXB Species Ischnura elegans 6N9HG Species Lestes barbarus 6Q33Z Species Libellula depressa 6PWQF Species Natrix helvetica 89JGM Order Odonata B6LCL Species Orthetrum brunneum 6SXLC Species Orthetrum coerulescens 759LG Species Pelophylax esculentus 76CHG Species Rana italica 6X364 Species Sympetrum fonscolombii 53P7C Species Sympetrum sanguineum 53P9J Genus Sympetrum sp. 9WN36 Species Sympetrum striolatum 7B6VS Species Triturus carnifex 595F2 http://www.w3.org/ns/dcat#keyword http://vocabs.lter-europe.net/EnvThes/21931 http://www.w3.org/ns/dcat#keyword http://data.loterre.fr/ark:/67375/BLH-ZHXZFTHT-Z http://www.w3.org/ns/dcat#keyword https://lod.nal.usda.gov/nalt/132549 http://www.w3.org/ns/dcat#keyword http://www.yso.fi/onto/yso/p10541 http://www.w3.org/ns/dcat#keyword http://aims.fao.org/aos/agrovoc/c_5312 http://www.w3.org/ns/dcat#keyword http://aims.fao.org/aos/agrovoc/c_8775 Nicolò Pellecchia Società Romana di Scienze Naturali Researcher nicolopellecchia99@gmail.com LifeWatch Italy lifewatchitaly@gmail.com The dataset was generated through field surveys carried out between March 2019 and December 2020 within the framework of a cooperation protocol between the Carabinieri Forestali and the Società Romana di Scienze Naturali. Thirty-eight field campaigns were conducted across different seasons to identify, map, and characterize small standing water bodies within the Monti Affilani massif and adjacent areas (Lazio, Italy). Each site was located using GPS and verified through topographic maps (IGM) and satellite imagery (Google Maps), complemented by local information. For every water point, structural and functional parameters were recorded, including altitude, morphology, dimensions, depth, and water supply type. Artificial and natural sites were measured using graduated poles and metric tapes (5–50 m). Biological observations targeted Odonata and Amphibia as ecological indicators. Species identification followed national reference guides (Galliani et al., 2015; Razzetti et al., 2025). Data consistency and quality control were ensured by repeated seasonal surveys and cross-validation among team members. Each water point was assigned a unique ID (PA01–PA33) and documented through standardized field forms archived in the digital database.

The area extends northwest–southeast between the Simbruini Mountains, the Arcinazzo Plateau, and the Ruffi Mountains, including the municipalities of Arcinazzo Romano, Trevi nel Lazio, and Affile. The region, rich in karst features and surface water points such as ponds and livestock troughs, represents a heterogeneous hydrogeological system of limestone and marly limestone substrates.
