Celebrating Stream Restoration

Ten years ago, our citizen scientists surveyed nearly 1,000 culverts and bridges throughout the Ashuelot River watershed to see where fish and aquatic wildlife movement were most impacted by roads. In the years since, we’ve worked with many partners to prioritize sites for stream restoration, based in large part on the data collected by our citizen scientists.

Now, restoration work is nearly complete on one of our highest-priority sites: an undersized culvert at Hale Hill Road in Swanzey has just been replaced with a new, flood-resilient and wildlife-friendly open-bottom arch crossing, re-connecting more than 20 miles of stream habitat in Falls Brook and the Ashuelot River for wild brook trout, dace, and other wildlife.

As with most things, partnership is the key to success, and we’re thrilled to be working with Trout Unlimited, the Cheshire County Conservation District, NHFG, NRCS, Keene State College, and the Town of Swanzey to restore fish passage to Falls Brook. We’re also grateful for support from the State Conservation Committee, NHDES, NHFG, the Town of Swanzey, and the NH Association of Conservation Districts.

To learn more about this exciting project, join us for a Volunteer Stream Restoration Workday on October 3, or for Why Did the Brook Trout Cross the Road? An Introduction to Fish- and Flood-Friendly Stream Crossings on November 17. For more information on either of these upcoming events, visit our online calendar or contact Brett Amy Thelen at (603) 358-2065 or thelen@harriscenter.org.

Hawkwatching with the Harris Center

In September, Broad-winged Hawks and other raptors begin their southbound migration, wheeling high along ridgelines in large groups known as “kettles.” When the timing and weather are just right, thousands of hawks may pass through the Monadnock Region in a single day. Experience this spectacular natural phenomenon alongside skilled naturalists at any of these fall hawk migration events:

Hawkwatching from Pack Monadnock on September 18
Pack Monadnock Raptor Release on September 24
“Big Sit” Migration Watch on October 9

For more information on these and other upcoming Harris Center offerings, please visit our calendar of events.

A Kettle of One

In September, the Harris Center’s Eric Masterson will walk out his front door, hop on a bicycle, and head south, not to return for another six months. He’ll be following the epic migration route of one of North America’s most iconic bird species, the Broad-winged Hawk.

Traveling in huge flocks called kettles, Broad-winged Hawks fly a narrowly defined path along the Appalachians to the Gulf Coast and Mexico. Many birds continue on into the heart of the Amazon basin. Both the birds and Eric − traveling in his “Kettle of One” − will cross five time zones, forty degrees of latitude, and five thousand miles, finishing in Colombia in February. Read more…
