Growth Rates of Important Reindeer Forage Lichens on the Seward Peninsula, Alaska
Cladonia alpestris, C. rangiferina and C. sylvatica may comprise 75-90% of all lichens eaten by reindeer. Their growth rates must be known to determine the carrying capacity, rates of recovery and patterns for rotational grazing of reindeer rangelands. Data from two sites near Nome and a third near...
