Monitoring invertebrates by pitfall trapping after excavation of the surface vegetation in two slacks at Newborough Warren, Ynys Llanddwyn Site of Special Scientific Interest (SSSI) in 2013.
This dataset contains information relating to the monitoring of excavated dune slacks at Newborough Warren, North Wales. The monitoring programme comprised invertebrate surveys focusing on two excavated slack sites further inland, together with an adjacent control site.
The dataset contains 12,838 individual invertebrate records representing 298 species.
The aim of the study was to assess, through pitfall trapping, the effects of excavating surface vegetation from two dune slacks and the dunes bordering their north-eastern ends on selected dune invertebrate species.
Some voucher specimens were retained and are held in the authors' private collections.

Invertebrate monitoring was carried out using pitfall traps. A total of 5,465 effective trap nights were achieved across 17 sampling sites.
All Coleoptera (beetles), Orthoptera (grasshoppers and related species), Diplopoda (millipedes), Chilopoda (centipedes), Isopoda (woodlice), Araneae (spiders), and Opiliones (harvestmen) were identified and counted.
Data from previous surveys were used to assess potential changes in the invertebrate fauna over the preceding 30 years. These findings are discussed in the associated report:
