"Those animals showing greatest sensitivity" to forest fragmentation “included [the] fisher, gray fox, spotted owl…" "Perhaps, the most critical problem facing forest wildlife worldwide, is the systematic shrinking and fragmentation of their habitat." P.263
"Most medium and large-sized mammals occurred less frequently in more insular stands or in 1000-ha blocks that were more fragmented. In particular, we found the presence of fishers to be more highly correlated with stand insularity…than with any other habitat measure." "Occurrences of fisher, gray fox… were… positively associated with stand area." "Fishers… decreased sharply in frequency of occurrence in stands <100 ha." P. 267
"Among the species suspected of being most sensitive to forest fragmentation in our study, only the fisher and spotted owl were also associated with old-growth forests." P. 271
