About 30 people explored the Prairie Garden Trust this morning on the first Wildflower Walk. Tim Smith, former botanist and current ombudsman at the Conservation Department, led the group through prairie and savanna to Hillers Creek, then past woods and the lotus ponds. While the prairie hasn’t come into peak bloom and the early spring flowers are done, there was still lots to see and learn. And the weather was delightful, too. In the photo, Tim was explaining how a “wolf” tree is formed and provides a clue to what the land looked like as the white oak tree grew its spreading branches.
