Join Paul Heiple and Ken Himes on an early spring walk along the Clarkia Trail in Edgewood County Park and Preserve. Plants of the serpentine chaparral and serpentine grasslands will be featured. In addition, Paul will comment about the improvements to the grasslands along the western Clarkia Trail as habitat restoration efforts continue to reduce the yellow star-thistle population. For example, plants such as narrow-leaf milkweed (Asclepias fascicularis) have increased dramatically.
