Learn about 'Walden’s Plants and Animals: From Thoreau to Today' at Highstead
REDDING .—A scientist who uses the observations in
"Richard Primack, professor of biology at Boston University, has used Thoreau’s journal to compare flowering times, the flight times of butterflies and the arrival of migratory birds from 150 years ago to today. By studying 32 spring-flowering native plants from a variety of habitats, Primack has discovered that they are now flowering much earlier. Migratory birds are also arriving earlier, but are changing less than plants," the release said.
“We are using Concord as a living laboratory to determine the effects of climate change on species, and land use changes on the population dynamics of native and non-native species,” said Primack, also in the release.
Prior to the talk, Ecologist Ed Faison and Operations Manager Geordie Elkins will give a guided tour of the Highstead property from 11 a.m. to 12:30 p.m., the release said.
"The public is welcome to join the walk and hear about the organization’s expanding observational studies and ecological monitoring that help document the natural world and changes over time."
An RSVP is required for both the guided walk and the lecture as space is limited: 203-938-8809.
Highstead trails will be open from 10 a.m. to 3 p.m. for self-guided tours and visits to the laurel collection in bloom.Editor's note: All information in this post was contributed, courtesy of David DeFusco, communications director for Highstead.
