Invertebrate data from Selected Grazing Marshes

Dataset homepage

Citation

Natural England (2023). Invertebrate data from Selected Grazing Marshes. Occurrence dataset https://doi.org/10.15468/88fiys accessed via GBIF.org on 2023-09-25.

Description

This dataset consists of invertebrate records from grazing marshes surveys that have, up until now, been held as spreadsheets with Natural England and were pooled into a spreadsheet in 2016. Some of this survey work is quite recent (2005), but the Walland Marsh survey dates back to 1982.

Purpose

The original purpose for the data collection was to inform on both site quality and site management of certain grazing marshes. The focus for this survey was the ditches, the fauna of grazing marsh ditches being known to often be of nature conservation importance. The reports summarise the quality of the ditches with respect the fauna they support.

Sampling Description

Quality Control

There is a high degree of confidence in the data. The recorders are known specialists (or are working with specialists) with plenty of experience. The 1985 Walland Marsh survey was lead by Margaret Palmer; Martin Drake being the principal worker for the later surveys in 2005.

Method steps

  1. The vast majority of the records come from aquatic survey using water nets to collect samples. These samples have been standardised for each survey, employing timed searches along specific stretches of ditch. Groups of particular focus include water beetles (Coleoptera), Snails (Mollusca) and Water bugs (Heteroptera) although other groups were also recorded.
