The USDI BRD Forest and Range Ecosystem Science Center (FRESC) provided funds for creating this site.

I appreciate the assistance of Janet Erickson, Ruth Jacobs, Betsy Littlefield, and the CFER management team in setting up the project.

I also appreciate the hard work by many graduate students and other scientists in obtaining and publishing their results. These people are too numerous to mention individually, but see the list of references for people who have made significant contributions to the field.
