Ecological notes on the heath community on Mt. Ebeko, Paramushir Island, northern Kuriles (scientific paper)
Although the northern Kuriles provide ecologically interesting issues on plant communities owing to their phytogeographical position between Hokkaido with its rich flora and Kamchatka with its poor flora, and to repeated volcanism of the islands, ecological studies of the plant communities in this a...

Although the northern Kuriles provide ecologically interesting issues on plant communities owing to their phytogeographical position between Hokkaido with its rich flora and Kamchatka with its poor flora, and to repeated volcanism of the islands, ecological studies of the plant communities in this area still remain insufficient. In 1997 we had an opportunity to visit the east slope of Mt. Ebeko, Paramushir Island, northern Kuriles. This paper documents the vertical distribution of the heath community on the east slope of the mountain at altitudes between 30m to 650m.
