Cranefly (Diptera; Tipuloidea) records for Britain to 2007

Biological Records Centre

Description

The data originated from Alan Stubbs and John Kramer of the Cranefly Recording Scheme and includes their own records as well as those collated from various recorders. This is part of a larger dataset collected by volunteers from the Scheme. The data were either received on recording cards and input in BRC (2004-5) or were sent in electronic format from the scheme organisers. Non-cranefly species are also present in the dataset. An update was made to the dataset in summer 2006 to include another 41000 records from the Cranefly Recording Scheme.

Geographic Description

Most records are from the UK, with reasonable coverage of England, Wales and Scotland. There are a small number of records from Ireland. The summer 2006 update contains records for England, Scotland and Wales only. Recording density varies but is particularly strong in parts of northern and south-eastern England.

Purpose

The reasons for data collection were to determine the national distribution and status of the fauna, including the ecology governing those factors. From the official launch of the scheme in 1973, the relevance to conservation and ecological assemblages/habitat management was seen as a high motivation.

Data quality

The scheme organisers selected which records were included in this dataset. Records were either determined by them from viewing specimens, or else selected for their accuracy by known determiners. Records typed into electronic format have been subject to routine validation by BRC.

Methods

Data collection was underpinned by providing workshops, new generation

keys and residential recording events, latterly under Dipterists Forum.
