Naturalization of Pinus mugo Turra (Pinaceae) in Southeast Sakhalin, Russia

Abstract

The paper presents information about the discovery of Pinus mugo with trees of various ages on coastal terrace between the Igrivaya and Ostrovka rivers (46o25'25N, 143o20'10E; Tonino-Aniva Peninsula, Korsakov District). Unlike other pine species that come from outside the district that have been cultivated at different times on Sakhalin, P. mugo reproduces well naturally. The dispersal of this species may be confined exclusively to the habitats found on the coastal terrace of Aniva Bay on the Sea of Okhotsk.
