A vascular plant inventory was conducted on St. Lawrence Island in the 1960s by Steven Young in which 250 taxa were documented. Since that time, very few collections have been made on the island. We conducted a vascular plant survey to improve our understanding of base Carlson-et-al-2018-St-Lawrence-Floraline floristics and identify populations of species of conservation concern.

The island received attention by early botanists, and thus provided some of the first collections in the region, by Chamisso and Eschschollz in 1816 and 1817 Carlson-et-al-2018-St-Lawrence-Flora near Southeast Cape, and Kjcllmann in 1879 in the northwest portion of the island.
