This Week in the Watershed: A Threatened Pennsylvania Hallmark

One of my most vivid collegiate memories occurred on the banks of a central Pennsylvania lake. While out in the field for an environmental science class, the Professor pointed out a handful of geese pecking away at underwater grasses and asked the class, "What should we do with these geese?" Upon the reply of several students saying we should protect them, he bellowed out, "WRONG! We should shoot them all!"

Despite the crassness of his response, his point resonates—invasive species can have major consequences on the ecological health of our rivers, streams, and the native species that call them home.

This week, the U.S. Geological Survey (USGS) released a study revealing that Pennsylvania's native brook trout is threatened by the invasive brown trout. Brook trout are commonly regarded as a "canary in the coal mine" for pollution, as they require cold and clean water for survival. As such, brook trout are particularly susceptible to warming waters as the result of climate change.

The USGS study found that the presence of the invasive brown trout is another significant challenge for the brook trout, as the brown trout has higher tolerance to warmer waters and competes with the brook trout for food sources.

Brook trout are a hallmark of Pennsylvania's rivers and streams. As a great indicator for healthy water, their dwindling population is telling. In addition to the need for strong fisheries management to address harmful invasive species, we need to fully implement the Chesapeake Clean Water Blueprint. Our children and grandchildren deserve clean water, and the proliferation of the brook trout will indicate we are headed in the right direction.

What's Happening around the Watershed?

November 20

  • Portsmouth, VA: Come on out to a fun-filled, family-friendly annual event that combines educational engagement and ecological stewardship. RIVER-Fest '16 will emphasize practices and activities that will sustain and improve the health of the Elizabeth River. CBF is looking for 6-8 volunteers to assist with a variety of activities. Please contact Tanner Council to register or for more information at tcouncil@cbf.org or 757-622-1964.

December 3

  • Broadway, VA: Come on out and help us plant hundreds of native trees and shrubs on a picturesque farm in the Shenandoah Valley. Volunteers should bring a sun hat, sun screen, and work gloves. Volunteers are also asked to bring a packed lunch. Light refreshments will be provided. This planting event is suitable for children closely supervised by adults. Please RSVP by November 30 to Robert Jennings at 484-888-2966 or RJennings@cbf.org.

December 6

  • Norfolk, VA: Join us for a presentation on what is often called,"the most important fish in the sea"—menhaden. An expert panel will discuss why menhaden matter and the future prospects for the fishery. This event is part of the Blue Planet Forum — a free environmental lecture series with a mission to educate and engage the public on important environmental issues affecting Hampton Roads and the nation. The event is free, but registration is requested — Register here!
