Plant Atlas 2020 - vascular plant and charophyte 2 x 2 km grid square locations, subdivided by survey period, up to 2019

These are presence-only data, indicating where a taxon was reported from a tetrad, within a given multi-year period, up to 2019. The Plant Atlas time periods cover the 20th Century but also extend back to the earliest botanical records known for Britain and Ireland in the first period (pre-1930), however, for earlier periods many records were made at lower than 2 km precision and so are excluded from this subset.

This 2 km square dataset summarise a subset of data collected mainly by volunteer recorders of the Botanical Society of Britain and Ireland (BSBI) between 2000 and 2019, as well as previous nationwide surveys undertaken in the 1950s and 1990s.
