Field Trip Sampler

Last weekend (March 26-28), I attended the Society for Ecological Restoration Mid-Atlantic Chapter's 10th Annual Conference at the University of Delaware in Newark, Delaware.  (For those not "in the know," never pronounce Newark, Delaware like Newark, New Jersey.  The New Jersey city is pronounced NEW-erk, whereas the Delaware city is pronounced new-WARK.)  Following a Thursday evening dinner at which I and eight colleagues were feted as founders of the chapter, the group re-convened the following morning for a day of formal presentations.  On Saturday, I participated in a field trip of three restoration sites within a half-hour's drive of the university.

Saturday was mostly cloudy, cold (high of 40 degrees F in the afternoon) and windy.  As we waited for the bus to depart, the group endured snow squalls.

Northern Delaware is DuPont territory.  Many of the wealthy heirs of the DuPont chemical fortune established expansive estates in the rolling hills of Delaware's Piedmont west of Wilmington, and some of these were sites we visited.  Our first stop was Mt. Cuba, a 500-acre estate that has been turned into a botanic garden featuring plants native to the Piedmont.  The 50 acres surrounding the mansion are a horticultural showplace and are beautifully maintained, but the remainder of the property (the part our group visited) faces the same challenges I face at my preserve: overabundant deer, invasive plants, and stream flooding.

Our second stop was the Delaware Nature Society's Coverdale Farm and Burrow's Run preserves.  At Coverdale Farm, we explored a wetland restoration project in which a wet cattle pasture formerly drained by terracotta tile pipes had been reflooded (by removing and breaking the pipes) in order to provide habitat for federally endangered bog turtles (Clemmys muhlenbergii).

Our group continued walking to the adjacent Burrow's Run Preserve, where the Delaware Nature Society has been converting pastures to native grasslands for grassland-nesting birds.  I literally was in awe and very jealous of their best fields, pictured below.  These fields support moderate growth of little bluestem grass (Schizachyrium scoparium) interspersed with dozens of species of forbs (i.e., wildflowers) - exactly the type of habitat meadow-nesting birds are seeking.  The grasses provide cover and the forbs attract insects for the birds to eat.  The fields at my preserve, in contract, are almost exclusively grassy with few forbs, which is why we haven't had luck attracting birds to my fields.

Our last stop was the Flintwoods Preserve, a 157-acre private (DuPont heir) estate whose claim to fame is a stand of ancient forest.  Our group, however, toured the native grassland restoration projects underway in the old agricultural fields on the property.

We parked our bus next to a renovated barn on the estate.  The barn is full of vintage baroque harpsichords that Peter Flint is in the process of restoring.  The Flints host sold-out baroque music concerts in the barn several times each year.

A humorous aside: as we were returning to the university following the field trip, driving through the northern Delaware countryside sprinkled with DuPont properties, one of the fellows on the bus quipped, "I keep looking at all these houses and imagining sexually-charged wrestling matches going on in each one." (a reference to last year's film Foxcatcher).  Of course, after he said that, I couldn't look at the places the same way myself!
