It is believed that the decline has been caused principally by habitat loss and more intensive use of pesticides on crops. In order to thrive, it is important that pollinators find nectar from plants available to them throughout the growing season.

Adapting to Beavers

Wednesday, June 5, 2019

North America’s largest rodent, the beaver (Castor canadensis), is supremely well adapted to life in and around fresh water. In December 2018, Conservancy staff discovered a new beaver dam and lodge at Waterloo Mills Preserve that had re-routed a stream and inundated the Preserve’s wet meadows.
