In episode 70 of Walk in the Park, we look at the attack by an invasive insect on our eastern hemlock trees in our forests and gorges and we find out what is being done in response. The schedule for cablecasts is below, along with the show online. And see the appeal for volunteers below!
This eastern hemlock tree at Robert H. Treman State Park in Ithaca, NY is infested with the hemlock woolly adelgid and has been marked for possible treatment. The needles on the branches in the canopy of the tree are already heavily thinned. If all the needles and twigs die, the tree will die. Hemlock trees are an important ecological and aesthetic component in our forests, particularly in our gorges.
We join Cornell forest entomologist Mark Whitmore in the Six Mile Creek Natural Area in the City of Ithaca, NY, in the watershed for the water supply for the city. Mark explains and illustrates how the hemlock woolly adelgid, an aphid-like invasive insect, is killing the hemlock, a “keystone species” in our forests, and what larger impacts this has in our forest and stream ecosystems. But it’s not hopeless. Mark explains the biological controls that are being implemented to save at least some of our trees and set the stage for our forests’ recovery from this disaster over the long term. See how YOU CAN HELP below.
We wrap up the show with two short, beautiful videos of Taughannock Falls this winter and last.
This episode of the show will be cablecast beginning tonight (Thursday, February 26, 2015) at 9:00 on PEGASYS public access television channels 13 and 97.3 in the Ithaca area; and it will repeat on Saturday and Sunday (3/22-23) at 10:00 a.m. and the last scheduled cablecast will be next Tuesday at 8:00 p.m. Or, you can watch it anytime ONLINE right here!
