To consider and plan for the re-introduction of grizzly bears into the North Cascades, one would want to know a few things first.

Such as;

  • how many grizzly bears are there now, let’s say, per one thousand square kilometers?
  • with climate change considerations, how would this affect what is considered to be prime habitat for grizzly bears?  (there are three prominent climate change models to consider)
  • with greenhouse gas projections, same question. How would this affect the grizzly bear’s survive-ability? (there are two prominent greenhouse gas forecast models to consider)
  • and then produce one result for all this in the 2050’s and again for the 2080’s

These people did just that.
