Conservation Partners to Restore Nearshore Habitat in Virginia

December 5, 2019 — The following was released by NOAA Fisheries:

The Chesapeake Bay is full of special places–including Virginia’s Middle Peninsula. Much of this area, which is bounded to the north by the Rappahannock River and to the south by the York River, is rural. Many residents make their livelihood from farming or fishing, thanks to the region’s vibrant ecosystem.

The waters surrounding Middle Peninsula are also treasured by people and wildlife alike, but like many parts of the Chesapeake Bay watershed, development, pollution, and runoff from upstream areas threaten their health. To ensure a healthy future for the habitat found here, NOAA and partners are working to restore nearshore habitat for fish and other Bay species.

NOAA and the Virginia Chesapeake Bay National Estuarine Research Reserve recently convened partners from around the Middle Peninsula to discuss the future for nearshore habitat restoration projects that support resilient coastal communities and economies. At the workshop, participants learned more about each others’ efforts, highlighting where they can work together most effectively.

The workshop also included presentations by experts on the importance of habitat to coastal communities in the area, how to use science throughout restoration projects, restoration project ideas that partners could team on, as well as opportunities for participants to make other plans for future work together.

As a result of enthusiasm for work in this geographic area, the Chesapeake Research Consortium is holding a competition (PDF, 5 pages) to help one or two organizations design a nearshore habitat restoration project in the watersheds of the York and Piankatank rivers and Mobjack Bay. The projects that receive funding will design a “shovel-ready” habitat restoration project to help reduce wave energy and erosion while providing nearshore habitat and coastal resiliency. Funding will go toward development of a project design and monitoring plan, making it easier for the project to receive funds for implementation down the road.

Chesapeake Bay health improves in 2015

May 18, 2016 — The overall health of Chesapeake Bay improved in 2015, according to scientists at the University of Maryland Center for Environmental Science. The largest estuary in the nation scored a C (53%) in 2015, one of the three highest scores since 1986. Only 1992 and 2002 scored as high or higher, both years of major sustained droughts.

“We’d expect to see improvements after a drought year because nutrients aren’t being washed into the Bay, fueling algae blooms and poor water quality,” said Bill Dennison, Vice President for Science Applications at the University of Maryland Center for Environmental Science. “However, in 2015 stream flow was below normal, but nowhere near the drought conditions in 1992 and 2002. Thus, the high score for 2015 indicates that we’re making progress reducing what’s coming off the land.”

The overall score for the Chesapeake Bay Health Index for 2015 was 53%, compared with 50% in 2014 and 45% in 2013. There were strong improvements in many regions throughout the Bay, such as the Choptank River, Upper Eastern Shore, Lower Western Shore, and the Rappahannock River. There were no regions that had lower scores in 2015 compared to 2014. Improvements could be related to a number of factors, including several years of moderate weather, sewage treatment upgrades, use of winter cover crops by farmers, and reductions in atmospheric nitrogen deposition.

These fish started life as boys. Now scientists aren’t sure what sex they are.

For male smallmouth bass, sex change is increasingly not an option. In the chemical-laced Chesapeake Bay watershed and in rivers up through New England, it comes with the territory.

Based on the latest U.S. Geological Survey on intersex fish, 85 percent of male smallmouth bass in waters in and around national wildlife refuges in the Northeast have developed “characteristics of the opposite sex.” That’s in addition to 90 percent of the species in some West Virginia waters and 50 percent to 100 percent in the southern stretch of the Potomac River. All of the affected fish had eggs where their testes should be, according to previous studies.

Why this is happening remains a mystery, says the lead author of a new study, despite the problem being detected more than a decade ago. “It is not clear what the specific cause of intersex is in these fish,” said Luke Iwanowicz, a USGS research biologist. “This study was designed to identify locations that may warrant further investigation.”
