...finally catching up to Laura's ASLA posts! I too had the opportunity to attend the annual conference in Chicago two weeks ago. I'd have to say that Chicago is my favorite US city and although we did get some time to explore beyond McCormick Place (rockin' blues and a salsa club that would make Ricky Recardo proud), the hi-light of the weekend for me was a full-day field session 40 minutes west of downtown to one of the most ecologically rich remnants of tall grass prairie. We learned that this 80 acre preserve owes its existance to the stock market crash of the 1920's. It was divided into residential lots in 1927, sidewalks were poured, but due to the crash that's exactly how it remained.
It is now the Wolf Road Nature Preserve and is managed by the IL Dept. of Natural Resources.

See the sidewalk?
Less than 1/100 of 1% of the Illinois prairie remains.
The plant to the far right is a "compass plant" named for its large leaves that follow the sun across the sky.

Our tour guide was Jack Pizzo of Pizzo Associates - a local company specializing in ecological restoration. Jack and his staff demonstrated several techniques from their tool kit including Seeding, spraying and may favorite... controlled burn. Much of the prairie shown here was burned about 1 year ago. It's a necessary step to maintain the prairie and control invasive species (the native americans practiced this method for 8,000 years and natural fires from lightening strikes also contribute). I'm wondering how often controlled burns are practiced in our region. They seem to be pretty common in the midwest. www.pizzo.info
