Orchids and Citizen Science at Hoyt - Guided Tour

Saturday, August 2, 12pm
$3/recommended donation, HAF members free!

Join Daniel Salomon, Hoyt tour guide and citizen scientist for an interpretative tour of a stand of uncommon Spiranthes ladies tresses orchids. Thought to be locally extinct, the orchids were rediscovered here at Hoyt by an arboretum visitor. During the tour, learn about the Citizen Science program and how this program is trying to empower ordinary citizens to contribute to scientific research about climate change. Then take a walk down the hill to a stand of ladies tresses orchids where Citizen Scientists are working with Hoyt Arboretum's taxonomist to explore preserving this precious orchid stand, propagating and expanding our ladies tresses orchid stand, removing invasive grasses and non-native wildflowers and recovering and restoring a remnant prairie wetland. The tour will end in a nearby temperate rain forest where Hoyt Arboretum has already engaged in restoration ecology, showcasing what is possible in terms of ecological healing. Tours meet at the Visitor Center. Pre-registration is not required.
