Protecting the “Most Important Fish in the Sea”
(Posted by Gerald Winegrad.)
Conservationists have been working for seven years to gain conservation measures for menhaden. This species plays an important role in the Chesapeake Bay’s ecosystem as a filter feeder, as a critical prey species for other fish and for piscivorous (fish-eating) birds. That’s why this keystone species has been called the most important fish in the sea.
After the Atlantic States Marine Fisheries Commission 2010 stock assessment found that menhaden are at their lowest point on record, the group is on the brink of adopting historic coast-wide conservation measures for this over-fished species. Yesterday, a group of 30 Chesapeake Bay leaders sent this letter to ASMFC urging restrictions on fishing this critical species.
Read MoreNutrient Trading—Promise or Pitfall?
(Posted by Dawn Stoltzfus.)
With the watershed states (Maryland, Virginia, Pennsylvania, New York, W. Virginia and Delaware) and D.C. working to significantly reduce pollution to meet the Chesapeake Bay TMDL, nutrient trading is a hot topic. Some see trading as a way to reduce the challenging costs of Chesapeake Bay cleanup, and it looks good on paper—but there are serious scientific concerns about its practicality and water quality benefits, particularly with trades between nonpoint sources (like agriculture and stormwater runoff) and point sources (like wastewater treatment plants). Difficulty in accurately measuring trading’s effectiveness also seems like a big obstacle.

Before Henry David Thoreau borrowed an axe and withdrew to the woods at Walden Pond, he spent a great deal of time daydreaming of owning a proper farm. He writes that “at a certain season of our life we are accustomed to consider every spot as the possible site of a house.” Toward this end, he had “surveyed the country on every side within a dozen miles of where I live. In imagination I have bought all the farms in succession.” He imaged how he would transform the land “into orchard, wood-lot, and pasture” and decided “what fine oaks or pines should be left to stand before the door.”
It seems that no one, not even the sage of Walden Pond, can escape from the pull of home ownership. In many ways it is the American Dream—white picket fence, grassy lawn, dog rolling in autumn leaves, every home a castle and every homeowner the king or queen of their castle. Entire television programs—no entire television networks—are based on the premise of buying, building or rebuilding the perfecting home (e.g., “House Hunters,” “Property Virgins,” “Curb Appeal,” and my favorite, “Flipping Out”—who can resist Zoila?).

(Posted by Gerald Winegrad).
The recent deluges leading to massive stormwater runoff into the Chesapeake Bay may cause great damage to an already seriously impaired system. We previously have discussed in this spot the huge flows of Bay-choking nutrients and sediment from farms each time it rains. Now, we will devote discussions to the pollution flowing from developed lands including huge amounts of nutrients, sediment, and toxic chemicals.
The Chesapeake’s watershed before 1607 was 95 percent forested with huge acreage of intact wetlands. These forests and wetlands absorbed and held nutrients and sediment. The flow of these Bay-killing pollutants was greatly accelerated due to enormous changes in land use when we converted forests and wetlands to agriculture and then, more recently, to development. The Bay region has since lost about 50 percent of its forest cover and 72 percent of its wetlands. No change has been more devastating for the Bay.
Read MoreHelping Local Officials Crack the WIP
(Posted by Mary Ann Lisanti.)
Two decades ago, when the Chesapeake Bay restoration effort began, the leadership of local officials was viewed as nice, but not essential. Times have changed. Today, with the deadline to develop local Watershed Implementation Plans looming, it’s clear that when it comes to improving the health of our local rivers and streams, and ultimately the Chesapeake Bay, the elected leaders of town and county governments and the appointed leaders of local soil conservation, storm water, and planning districts throughout the Chesapeake watershed will be the ones to make it happen.
However, the feedback coming from local government is simply this: They need information, direction, and flexibility in choosing approaches, otherwise budget challenges will keep them from reaching their goals.
Read MoreIs It Illegal to Restore the Bay?
(Posted by Erik Michelson.)
After centuries of unregulated wetland filling, land clearing, and shoreline modification, over the course of the past several decades, federal, state, and local regulations have been put in place ostensibly to reverse the trend of the declining health of the country’s waterways. As a rule, these have taken the form of a sequence of three options: “avoid, minimize, mitigate.” So, in the context of a development project, impacts to wetlands or trees in the critical area buffer should be avoided if at all possible, and if not avoided, minimized. Any impacts that do occur, should either be mitigated, or offset, preferably on the same site where they originally occurred, but if not there, somewhere else in the same jurisdiction.
