Unionville Barrens Naturalist Walk
Delaware Nature Society program, September 12, 2013

Visit the Unionville Serpentine Barrens to learn about the ecology of this rare habitat. Seek unusual plants, and look for migrant songbirds during the height of migration. This site is one of the few small Serpentine Barrens that remain east of Nottingham and is undergoing a habitat restoration with associated research projects. Bring a bag lunch and a drink. -- Leader: William Ryan

Most photos were taken at the ChesLen Preserve.

Also see this blog post describing a plant conservation project at the site.
