Description
This dataset, collected since 2021 as part of a research project led by CEFE and IMBE, documents the presence of the red squirrel and other small mammals across several study areas, including the Montpellier metropolitan region (France). The project aims to investigate the effects of landscape fragmentation on population connectivity.
The objective is to better understand the spatial distribution of individuals and their ability to move between habitat fragments in urban and peri-urban environments. Sampling was conducted using a network of hair traps installed across landscapes exhibiting varying degrees of fragmentation.
These devices enable mammal detection through hair collection, which is then used for species identification and individual genotyping. The dataset includes occurrence data of red squirrels and other small mammals by trap and sampling site, derived from hair sampling.
Hair samples were subject to genetic analyses for species and individual identification; however, the genetic data are not included in this dataset.

Méthodes d'échantillonnage
Sampling was carried out using a standardized network of hair traps deployed across selected habitat fragments. Traps were installed on trees or suitable structures to maximize detection probability of red squirrels and other small mammals. Each device passively collected hair samples during deployment periods. Collected samples were retrieved during scheduled field visits. Hair material was subsequently used for species identification and, when possible, individual genetic identification. This non-invasive protocol allowed repeated detection without animal capture, ensuring minimal disturbance while enabling monitoring of presence across fragmented landscapes.
| Etendue de l'étude | The study was conducted across multiple sampling sectors in southern France, including the Montpellier metropolitan area and surrounding peri-urban landscapes. Sampling sites were selected along gradients of landscape fragmentation, encompassing continuous woodland patches, isolated forest fragments, urban parks, and suburban green infrastructures. The spatial extent reflects a diversity of habitat configurations representative of Mediterranean urban and peri-urban environments, enabling the assessment of connectivity patterns for arboreal and small terrestrial mammals. |

Description des étapes de la méthode:
- Hair traps were installed at predefined sampling locations following a standardized deployment protocol. During each collection session, hair samples were carefully removed, labeled, and stored for laboratory processing. Field metadata, including trap location, installation date, and collection date, were recorded. Samples underwent morphological and genetic analyses to confirm species identity and, where feasible, individual assignment. Occurrence data were then digitized, standardized taxonomically, and formatted according to Darwin Core specifications. Quality control procedures included coordinate validation, date verification, and harmonization of observer and sampling information prior to dataset publication.
