Bedfordshire Isopoda (BNHS) - 1975-1984

Quality Control

Observations have been verified by the County Recorder who also undertook much of the surveying. Although some unintentional inaccuracies may be present, none are currently known.

Method steps

1. A systematic survey of the tetrads of the county over the period 1975-1979 followed by a period of less-intensive recording to 1985.
   The majority of records were provided by amateur naturalists who are members of the Bedfordshire Natural History Society (BNHS).
   Records were collated by the BNHS County Recorder for Isopoda, Chilopoda and Diplopoda, who also undertook much of the survey work.

The records cover the modern administrative areas of Bedfordshire (now Bedford Borough and Central Bedfordshire) and Luton, and/or Vice County 30. (It is currently unclear which boundaries limited the survey area).
As the tetrads were systematically surveyed coverage of the county should be relatively good. Published summary maps to 1979 show six or more species recorded from most tetrads.
The records within this dataset are only the 10km square summary that was published in Bedfordshire Naturalist No.34 (for the year 1979) and the subsequent follow-up in Bedfordshire Naturalist No.39 (for the year 1984). (No additional records were added in 1985).
The individual tetrad records are unfortunately not currently to-hand (to the BRMC).
Three records (for 1981 to 1982) carry 100m grid references. All others are 10km square species-list summaries.
