Re: ?

I know that for Illinois, once there were 22 million acres of tallgrass
prairie; but, today there in approximately 2400 acres or only 0.01%
remaining.  NOT 1%, but 1/100 of 1%.

I cannot speak to the precipitation question.

I have documentation for Illinois from the Prairie Restoration Handbook
published by the Illinois Dept. of Natural Resources.  I could send a copy
of this publication if I was given this person's address.

I would check with the other state departments for accurate figures.

Hope this helps.
