Citation

British Lichen Society (2017). BLS Lichen Database: Wales churchyards 1700-2016. Occurrence dataset https://doi.org/10.15468/mzl8ef accessed via GBIF.org on 2022-05-16.

Description

A collation of the available lichen records for churches, graveyards and burial grounds in Wales from 1700 to January 2017, for purposes of conservation, future monitoring and research. Habitat and substrate information is included where available.

Purpose

To collate data on lichen distribution, changes over time, and the conservation value of particular sites

Sampling Description

Quality Control

The dataset has been validated and verified by experts, and also checked using the NBN Record Cleaner. However, some errors of identification or location are bound to remain. Also, this dataset should not be regarded as having comprehensive geographic or taxonomic coverage. The absence of a record does not necessarily indicate absence of the lichen. Presence and absence data should be checked against original sources before use in contentious circumstances, and specialist advice sought where appropriate.

Method steps

  1. 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 Wales, however surveys have been targeted on particular 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.
