Here at the National Plant Monitoring Scheme, we are pleased to be able to make all the data collected by our brilliant NPMS volunteers open and freely accessible to others.
We have published our data in various ways since the beginning of the scheme in 2015 (e.g. see our Conservation and Research page), with the full dataset published annualy on the Natural Environment Research Council's Environmental Information Data Centre (EIDC).
See this page for the full collection, and this dataset for the 2022 update. There is also now available a separate summary of surveyor-recorded NPMS habitat data, including whether or not the habitat type is reported to have changed between surveyor visits.
