Abstract:

A 90+ year-old burn in the Raft River Mountains, Utah, is being restocked with limber pine (Pinus flexilis James) and other conifers. Limber pine's large wingless seeds are incapable of wind dispersal, and are being brought to the burn area by Clark's nutcracker, a bird that stores them in the soil for food. Unretrieved seeds germinate, often in clumps, and are reestablishing limber pine on this site. In some years nearly the entire seed crop may be harvested by nutcrackers. No other reliable dispersal agent of limber pine seed has been identified.
