Winter walk at Ives goes on

This is the spring where yesterday's rill originates.  It's the one spot in the preserve where the plant cover gets thin enough to expose the oozing substrate of marl and gravel.  Not very photogenic in this season.  In warmer times it is the best spot to see some of the Preserve's more unusual plants.  The exposed marl gives this water an exceptionally high concentration of very basic minerals and low levels of nutrients.  The plants that grow here include two insectivorous species and three orchids, all able to supplement their diets.  Otherwise, it's mostly little things in the sedge family that are adapted to these extremes.
