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.
Purpose
For personal interest and to increase knowledge of the distribution and local status of species.
Sampling Description
Quality Control
Very good.Method steps
- 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.
