Bob Merritt dataset of Nottinghamshire invertebrates
Nottinghamshire Biological and Geological Records Centre
Description
The great majority of records are of wetland invertebrates, especially water beetles and water bugs, with a significant minority being of spiders, rove beetles, ground beetles, dragonflies and molluscs, plus a few other groups. Almost all records have been generated during the past 25 years by the fieldwork of Bob Merritt, the exception being a small number of Environment Agency records, the IDs of which were determined/confirmed by him.
Geographic Description
The current administrative County of Nottinghamshire and the Watsonian Vice-county of Nottinghamshire (Vc56).
Purpose
For personal interest and to increase knowledge of the distribution and local status of species.
Data quality
Very good.
Methods
Most records of aquatic species, and many wetland spiders (often inadvertently), were obtained by means of a pond-net. Most records of non-aquatic species were obtained by sweeping, sieving, grubbing and pitfall-trapping. The IDs of all records were verified either by Bob Merritt or by other people with a very high level of expertise. Records were computerised using Recorder software. All grid references that were not obtained by a GPS unit were established (or checked in the case of Environment Agency data) using a graticule in conjunction with the relevant OS 1:25000 series map.
