Thank you Kimberly. I spoke to a long time forester this morning and his
estimation was that there could be 'on average' in optimal (happy) conditions
200 Ponderosa Pines per acre, 30 inch diameter (150 to 250 years old). I'll
check these web sites, hopefully one will show how many acres on average the
US is cutting down each year.
Thanks, I really appreciate your help.
