The Tamarack Nature Preserve in Woodbury is a “bog fen,” a rare wetland combination. Bogs are rain-fed, acidic, and nutrient-poor for plant growth. In contrast, fens are fed at least in part by mineral-rich ground water and have a more basic pH. Different plant species are found in each. But the peat wetland at Tamarack Nature Preserve is a rare combination of both. Here ground water rich in minerals seeps into the bog wetland. Bog and fen plant species occur together.

Nationally recognized botanist and author, Dr. Robert Mohlenbrock, of Southern Illinois University, has visited the Preserve, discovering its interesting ecology and rare mix of plants . Join this Zoom presentation to hear Dr. Mohlenbrock describe what he found in this wetland gem, and to discuss how we can protect such special places hidden in our midst.

This presentation is free and the public is welcome. Register here.
