Results of the Study of Bryophytes in the Territory of the Gardens of the Russian Museum

The Summer and Mikhailovsky Gardens are the first gardens of St. Petersburg and are under the management of the Russian Museum. In the gardens a survey and monitoring of green spaces is carried out, within the framework of which a study of bryophytes was conducted. Based on the monitoring results, adjustments are made to the measures for the care of green spaces. The aim of the work was to collect all currently available information about bryophytes in the territory of the city’s first gardens. The study was carried out by visual inspection, the finds were photographed, dried, studied in laboratory conditions under a binocular microscope, and the locations were mapped. As a result, 32 species of bryophytes were discovered for the Mikhailovsky Garden, and 24 species for the Summer Garden. In total, 49 species of bryophytes have been found in the gardens of the Russian Museum, which is about 16% of the bryophyte flora of St. Petersburg. During the work the following were discovered: the moss Orthotrichum diaphanum, protected in St. Petersburg, and the moss Myrinia pulvinata, protected in the Leningrad Region. Most species of bryophytes grow in the gardens of the Russian Museum on the soil of lawns and along the edges of paths. The list of bryophytes the gardens of the Russian Museum, should be considered as a scientific basis for subsequent monitoring studies.
