British Lichen Society (2018). BLS Rare and Threatened Lichen Records: England. Occurrence dataset https://doi.org/10.15468/pamwp1 accessed via GBIF.org on 2018-09-23.Description
A collation of the available records for rare and threatened lichens and lichenicolous fungi in England from 1700 to 2011, for purposes of conservation, future monitoring and research. Habitat and substrate information is included where available. Species are included if they are nationally rare or scarce, or have a conservation status other than least concern, data deficient or not evaluated.Purpose
To collate data on lichen distribution, changes over time and the conservation value of particular sites.Sampling Description
Quality Control
The data should not be regarded as having comprehensive geographic or taxonomic coverage. The absence of a record does not necessarily indicate absence of the lichen. The data should therefore be checked against original sources before use in contentious circumstances, and specialist advice sought where appropriate.Method steps
- The dataset has been compiled from field and herbarium records, and verified by specialist review.
Taxonomic Coverages
Geographic Coverages
The dataset covers the whole of England, including the Isle of Man. However surveys have been targeted on particular habitats and geographical areas at different times and the coverage of available records is not complete. The majority of the records are collated with summary 10km or 1km grid references, but some more recent data has six or eight figure grid references.
