The study of the flora of the city of Ryazan using the grid mapping method with the cell size of 1.4 km2 (latitude 0.01°, 1290 m; longitude 0.02°, 1110 m), allowed us to reveal the presence of Solidago canadensis in all of the 97 surveyed cells. The use of electronic resources (iNaturalist and Yandex Maps) resulted in its detection in another 16 cells; S. gigantea was found in 13 cells. The highest number of S. canadensis individuals and the largest area of their spread were observed in the city outskirts, which have rather recently become cultivated for growing the grain crops (approximately 10 years ago). S. canadensis often dominates on fallow lands included within the boundaries of the urban agglomeration. The major role in the Canadian goldenrod spread is played by multiple individually cultivated community gardens, as well as flower gardens and planted areas in private space. No appreciable dispersal of S. gigantea has been yet observed in Ryazan; the species forms small populations. [ABSTRACT FROM AUTHOR] |
