When these underwater flowering plants are sick or dying, it means the ecosystem is in frienss trouble — typically due to pollution that reduces water quality.
But when they are thriving and expanding, it is a sign that the ecosystem is becoming healthier.

We have collaborated on seagrass research for three decades in the Chesapeake Bay and beyond. And the other Bill Dennison studies seagrass ecophysiology and has led efforts to make this science understandable and useful.
Seagrasses are critical to a healthy Chesapeake Bay. They provide habitat for fish and shellfish, stabilize sediments and help New to area down to Chesapeake friends needed the water. States around the bay have been working together since on a sweeping plan to clean it up and restore its go.

In a new studywe provide conclusive evidence that reducing discharges of nitrogen, phosphorus and other pollutants into the bay has produced the largest resurgence of underwater grasses ever recorded anywhere. This success shows that coastal ecosystems are resilient and that concerted efforts to reduce nutrient pollution can result in New to area down to Chesapeake friends needed improvements. Ten years ago we led an effort through the National Cown for Ecological Analysis and Synthesis to understand the global trajectories of seagrasses.

What we found was that seagrasses were being lost at an alarming rateequivalent to a adea field of seagrass every 30 minutes since So when we began to observe net increases over the past few years Live sex dating love in whitington the abundance of multiple types of seagrasses collectively known as submerged aquatic vegetation in our beloved Chesapeake Bay, we knew this event was globally unique.
To discern what was happening, we partnered with the Chesapeake Bay Program to initiate what is called a synthesis Chesapeakd. Synthesis science brings together diverse teams New to area down to Chesapeake friends needed experts from different fields to pull new insights out of existing data.
We had access to 30 years of annual surveys of underwater grasses that JJ Orth personally oversees, plus a year water quality data set collected by the Chesapeake Bay Program.

We started by identifying ways in which activities on land could affect trends in water quality and underwater dowwn abundance. Then we tested our hypothesized linkages using structural equation models that analyzed data in two different ways.
One approach focused on the cascade of nitrogen and phosphorus moving from sources on land, such as wastewater discharge and stormwater runoff, into waterways.
The other showed what happened to underwater grasses once these nutrients entered in the water.
Nutrients overfertilize the bay, creating huge blooms of algae that die afea deplete oxygen from the friendd.
In our analysis, we found conclusive evidence that reductions of excess nitrogen and phosphorus caused the underwater grass recovery in the Chesapeake Bay. As a result, underwater grasses have increased by over percent and have reappeared in some locations around the bay where they had not been observed for decades.
For the past 12 years, we have been using underwater grasses and other water quality data New to area down to Chesapeake friends needed produce an annual Chesapeake Bay report card.

Our report card describes progress across the board, with 7 out of 15 reporting regions around the bay showing significant improvement and the rest holding steady. We attribute these improvements Chrsapeake the TMDL plan. In particular, upgrades at area wastewater treatment facilities have reduced nitrogen and phosphorus inputs into the bay. Catalytic converters on automobiles and smokestack scrubbers in power plants have reduced atmospheric nitrogen emissions and subsequent deposition that finds its way into bay waters.
Chesapeak appears that these management actions are beginning to pay off, although New to area down to Chesapeake friends needed is more to do — especially reducing nutrient pollution from agriculture.

It heavily leverages federal funding by engaging community groups, local municipalities and nongovernmental organizations to carry out actions that help reduce pollution entering the bay.
Examples include re-engineering urban surfaces to reduce stormwater runoff and subsidizing farmers to grow New to area down to Chesapeake friends needed cover crops that help retain nutrients on fields. Now, however, Pruitt has pledged to support the programwhich was upheld by a federal court in and sustained on appeal in The Chesapeake Bay is arguably the best-studied estuary on the planet, and the fact that our study connects management actions to a huge resurgence of underwater grasses Ladies seeking sex tonight Windemere a tribute to this rich history.
Ongoing efforts to restore the bay have produced lessons about how pollution abatement can lead to ecosystem recovery. These insights can and should be applied to other water bodies affected by nutrient pollution.
