Pat, it was only 3 months ago that a senior University of Kansas
entomology professor, Dr. Chip Taylor, proclaimed in the popular press that
"We have a major [Monarch Butterfly] conservation crisis"

And in a peer reviewed journal in 1989 Dr. Lincoln Brower 
predicted the extinction of the eastern USA monarch migration 
phenomenon by the year 2000.

Pat, Art Shapiro said: "DIRE straits faced by MOST of our butterfly 
fauna" [of the lower Sacramento Valley = about 90 species]

So Shapiro is saying MOST of those 90 species are in dire trouble. 
Here are Shapiro's species lists for his lower Sacramento Valley
study sites:

North Sacramento: http://butterfly.ucdavis.edu/sites/north_sac
West Sacramento: http://butterfly.ucdavis.edu/sites/west_sac
Rancho Cordova: http://butterfly.ucdavis.edu/sites/rancho
Suisun Marsh: http://butterfly.ucdavis.edu/sites/suisun
Gates Canyon: http://butterfly.ucdavis.edu/sites/gates

Is it reasonable for Shapiro to proclaim most of these 80
species are in "dire straights"?
