In Yellowstone, the best foods are, of course, the fattiest, including the seeds of whitebar

Contingencies of Coexistence, Part II: Diagnosing the Landscapes

In part one of this two part series I offer my take on how the heterogeneity of those involved in the drama of cohabiting with wolves and grizzly bears can be usefully parsed for diagnostic purposes. My four broad categories are Regressive Reprobates, Reluctant Pragmatists, Uninformed Innocents, and Affirmative Innovators, each denoted with a name that is hopefully partly self-explanatory. For more on each see Part I, Parsing the Participants. My take is specific to the northern US Rocky Mountains, but with potential relevance to other regions in North America, even other parts of the world. Categorizing participants is but a first step. The most useful follow-on applications are to first re

Find out how much Native Americans care about the grizzly bear, with a Grizzly Treaty that has been signed by more than 270 tribes, as well as numerous traditional societies and leaders. The document has become a symbol of international unity in defense of sovereignty, spiritual and religious protection, and treaty rights. 


For an in depth and comprehensive look at the ecology and demography of grizzly bears in the northern US Rocky Mountains, along with all the research relevant to conservation of these bears, see Mostly Natural History of the Northern Rocky Mountains.
