Rocks are excellent places to study lichen growth forms, biology, and ecology. Native rock walls, cement walls, and cemetery monuments made from different rocks boast a diversity of rock-colonizing lichens common to New England. During this March 14 Native Plant Trust class at Garden in the Woods and a field site, you will learn about lichen identification, reproduction and growth, and habitat interactions through a stereoscope workshop and field application at local cemeteries. Elizabeth Kneiper leads. $75 for NPT members, $90 for nonmembers. Register at http://www.nativeplanttrust.org/events/rock-lichens/
