      Recommended interesting reading in these firestorm days might be:

      "Restoring North America's Birds: Lessons from Landscape Ecology"
      Robert A. Askins
      2nd edition, 2002, Yale University press; paperback, 17.95
      ISBN 0-300-09316-0

      Particularly pertinent might be Chapter 7: Birds of the Western Mountain
      Slopes, and especially pp. 158-162, on "Fire and the Western Forest" plus closely
      related topics.

      "Next to differences in altitude, fire is probably the most important factor
      for inducing diversity in western forests. Most of the mountain forests of
      the West burn periodically and relatively predictably, but there is wide
      variation among forest tyupes and regions in both the frequency and intensity of
      fires. Frequency and intensity are closely associated: where fires are
      infrequent, there is often an accumulation of dead wood that fuels intense
      fires.....Forests with infrequent fires may appear stable over the short term, but they are
      prone to sudden and catastrophic change."

      The above simply is a short sample of the very readable text, which provides
      any number of examples and lessons, regarding a wide variety of landscapes and
      habitats. The same chapter, for example, delves into issues of Pinyon Jay
      distribution, that being a species whose extension out of its usual areas has
      caused some comment recently.
