I have to disagree here... unless "grass" is considered one species and
"tree" another prairie and even relatively uniform forest are still a far
cry from monoculture... 

I agree, nature seldom creates a "monoculture". I have a five acre woodlot and there are at least a dozen or more species of tree, various shrubs, lots of small wild flowers. In the pastures next door there are again many different species including many grasses, wild flowers, and tons of goldenrod. Many of these species bloom at different times so there is a long bloom period. Beyond that, even agriculture in our region is very mixed, with apples, pears, row crops, woodlands, swamps, villages, cities etc. The monoculture that exists in the midwest and west is not seen in the eastern states.
