With the use of records in the Leningrad region (herbarium collections since the 18<sup>th</sup> century and scientific publications over the period from 2000 to 2014) a database of red-listed vascular plants was created. The database consists of 6745 unique records dating from 1779 to 2014. The changes in collection effort and distribution of floristic observations of the Leningrad region which have occurred over the last 200 years are demonstrated. The South-West districts of the region remain the most observed, and Eastern areas are still less studied during the whole period. The other biases caused by and limitations in using the records are discussed. Refs 27.
