fellow at The Farlow Herbarium, Harvard University, Cambridge,
Massachusetts. Trappe’s participation was supported in part by the
U.S. Forest Service, Pacific Northwest Research Station, Corvallis,
Oregon; CSIRO Sustainable Ecosystems, Canberra; and a grant from
the North Coast and Cascades Research Learning Network.
Personnel of Kosciuszko National Park in Australia and North
Cascades National Park and Gifford Pinchot National Forest in the
