In 2019, scientists from the V.L. Komarov Russian Academy of Sciences and St. Petersburg State University for the first time in history conducted a special study of lichen diversity on Medny Island. This year Dmitry Gimelbrant and Irina Stepanchikova returned to the protected Commander Islands to study the lichen flora of the other islands of the archipelago.
Scientists have carried out work in different parts of Bering Island, on Toporkov and Ary Kamen Islands. During this season, they managed to lay more sampling areas and collect representative material for further laboratory study.
