Now that too seems to be changing. There has always been a spiritual dimension to the environmental movement. Thinkers like Emerson, Thoreau, and Muir often used spiritual metaphors to describe the benefits of wildlands and invoked ethical arguments in favor of wilderness preservation (Kline 1997; Gottlieb 2004; Dunlap 2006). Aldo Leopold’s famed land ethic is fundamentally spiritual (Leopold 1949). But as science came to dominate the politics of environmental protection, the spiritual fire began to dim.

Anderson 1983. Pad measurements tend to be more consistent than total paw measurements. Substrate produces some variation. Fjelline and Mansfield (1989) recommend measuring the flat bottom of the track. Anderson 1983. Hind paws are smaller and narrower than front paws. On level ground, hind and front feet register in the same tracks and only hind paw track is visible. Anderson 1983. Paw length is a variable measurement, depending upon substrate, posture, and rate of movement. Anderson 1983. Not a standard measurement, unclear how taken, depends on how leg is extended, should be taken on live animal; likely biased high.

It is both enigmatic and true that if we are wise enough to save the mountain lion (cougar), ultimately, the mountain lion may save us. I can hear Lame Deer, Black Elk, and others chuckling in the background. This is the fundamental wisdom they tried to teach us centuries ago (Neihardt 1961; Erdoes 1976). Chapter 2 The Emerging Cougar Chronicle Harley Shaw T his ch a p t er is a history of cougar research, addressing the question of where we have been. Extensive field studies of the cougar over the past fifty years have given us a better understanding of the big cat’s natality, mortality, genetics, dispersal, diet, home range, social structure, and behavior (see Young and Goldman 1946a; Barnes 1960; Anderson 1983; Tinsley 1987; Hansen 1992).
