Growth rates of important reindeer forage lichens on the Seward Peninsula, Alaska
Pegau RE. 1968. Growth rates of important reindeer forage lichens on the Seward Peninsula, Alaska. Arctic. 21(4):255-259
The average annual linear growth rate of three species of Cladonia lichens (thought to comprise 75-90% of all lichens eaten by reindeer) was measured at three sites: in the foothills west of the Snake River, at Dexter Creek, and near Koyuk. Values obtained ranged from 5.0 to 5.4 mm. C. rangiferina achieves the podetium renewal period in 5.9 years, almost half the time needed by the other two species. The average rates were higher than those of northern Canada and some areas of the USSR.
