Second Opinion on Mute Swans

Second Opinion: An invasive species is an invasive species - A virtual meeting of The Sun's editorial board, where issues are discussed, opinions made - baltimoresun.com
excerpt from above:
Quote:
Six years ago, a coalition of state and federal agencies launched an effort to eradicate nutria from Blackwater National Wildlife Refuge where the animals, a species native to South America, had destroyed thousands of acres of marshland. They appear to have succeeded and the effort is seen as a great victory for the environment.

Maryland officials have also been trying to remove another invader, mute swans that have destroyed submerged aquatic vegetation, habitat that is considered extremely valuable to many native Chesapeake Bay species. But instead of a triumph, the next and perhaps final step in this effort is seen as a "slaughter" of the remaining 500 or so of these "beautiful" animals by protesters.

What's the difference? The only significant one is human aesthetics. People love to look at swans with their white feathers and elegant long necks. Not so much with nutria, which might generously be described as a cross between a beaver and a rat.

Default Maryland to Continue Killing Mute Swans

Maryland to Continue Killing Mute Swans

excerpts from above;
Quote:
The Maryland Department of Natural Resources will continue to kill mute swans and destroy their eggs in an effort to keep the invasive species from devouring marsh grasses vital to the Chesapeake Bay.
Quote:
"While the swans may be beautiful, they continue to pose a serious threat to the Chesapeake Bay and its native wildlife, and non-lethal controls have proven insufficient for reducing the population," DNR Secretary John R. Griffin said in a statement.
Quote:
Two animal rights advocates on the 12-member task force issued their own report last month, arguing that "it is simply preposterous for Md. DNR to allege that a few hundred Mute Swans have any measurable negative impact on aquatic vegetation in the Bay."

Quote:
They also will kill live swans by shooting them or using a device to break their necks. DNR officials said all of its methods are approved as humane, though animal-rights activists disagree.
Quote:
The state has targeted mute swans (Cygnus olor) because they are not native to Maryland and have a voracious appetite for underwater grasses. They can eat 8 pounds of grasses a day, which can hurt other waterfowl that feed on the grasses, as well as crabs and other aquatic critters that live in them.
Quote:
Maryland's population of mute swans can be traced to five birds that escaped captivity in Talbot County in 1962. The population grew to 4,000, but has been thinned to 500 in recent years.

The guy who authored the first article is right on the money, "While my colleage, Glen McNatt, may see beauty in the mute swan, perhaps he should poll the terns, black ducks and other waterfowl that suffer because of the swan's presence. Not to mention the juvenile blue crab and fish that depend on underwater grasses for their survival.
What's needed is to bring the system into balance. The Maryland Department of Natural Resources really has two choices -- eliminate the invaders completely now or gradually over time. The second option is an expensive indulgence. The money would be better spent on restoring habitat.
To mute swan lovers that may sound cruel, but it's the way nature works (and the way wildlife management should). Their appearance doesn't make them any less harmful to the environment. We don't cry for the zebra mussel, the northern snakehead fish or the grass carp. They are understood to be pests. Let us not assign value to another invasive species because it happens to suit our human criteria for beauty." That last statement of his is powerful. The mute swans are destroyed in my county. They are quiet about it to avoid problems from the swan lovers.

Yup, and it's probably simply preposterous for a doctor to allege that a small cancer tumor has any measurable negative impact on the human body.

If there are only a few hundred of them why can't they be rounded up and put in a protected environment?

There may only be a few hundred remaining in the Chesapeake Bay area however there are tens of thousands wreaking the very same havoc in the environment in other regions. Habitat is too precious, it must be set aside for our native species. They're attempting to protect the environment from the Mute Swan.

There's only a few hundred because they destroyed the habitat, and it can no longer support 4,000+. Sort of like over-populated deer and anything below the 4-foot browse-line.

is not a "few" hundred.
When natural habitat is so limited even a "few" alien species can threaten natures.
