Trees among the tundra
TOOLIK FIELD STATION, ALASKA– Balsam poplar is the northern-most tree species in North America. In Arctic Alaska, it occurs sporadically in isolated stands often adjacent to perennial springs or on south-facing slopes. Join our field crew as we venture into one of these stands north of Toolik Lake. Our aim is to investigate a report from a colleague, Dr. John Hobbie (the former director of the Arctic LTER), of an errant spruce tree. Spruce, specifically white spruce, reaches its northern-most limit south of the Brooks Range. If a spruce tree is indeed present, it would be a significant find.
