On The Brink Of An Environmental Disaster — Weed Science Society Of America Highlights Progress Against Hydrilla Infestation In Finger Lakes Region

Six months ago one of the world’s most aggressive aquatic weeds was spotted in an inlet adjoining Cayuga Lake, part of New York’s famed Finger Lakes. The culprit was hydrilla (Hydrilla verticillata), an aquatic plant species holding a well-earned spot on the federal noxious weeds list. Officials fear an environmental disaster in the making—and for good reason.

RSPB’s Llandudno Junction reserve salt water to kill swamp stonecrop weed

Salt water is to be used to kill off a weed which threatens a freshwater lagoon at an RSPB reserve where thousands of birds feed on mud flats. About 7m gallons (32m litres) is being pumped from the River Conwy into the lagoon at Llandudno Junction from high tide on Thursday. It is designed to eradicate an invading weed from Australia, known as swamp stonecrop, or Crassula helmsii. The lagoon had already been emptied and will be kept salty for at least a year.

How Much Hydrilla? The Kissimmee Chain Debate

Fishermen and duck hunters on the Kissimmee Chain of Lakes have been in conflict with each other, as well as the Florida Fish and Wildlife Conservation Commission, for the past nine months — all over a submerged aquatic weed called hydrilla that is as common to most Florida lakes as St. Augustine grass is to urban lawns.

“They’ve got a tough job. I wouldn’t want the job to manage hydrilla to please everybody,” said professional bass fisherman Terry Seagraves of Kissimmee.

Low water now means a summer filled with weeds

Not only is Clear Lake at its lowest level in years but the water clarity is unbelievable. In many areas you can see the bottom at a depth of 6-8 feet. The low lake level and extreme water clarity will have a profound effect on the fishermen. It will also result in an explosion of aquatic weeds by midsummer.

Aquatic invasive species creeps into Flathead Lake

A reported sighting of Eurasian watermilfoil in Eagle Bend Yacht Harbor waters led to the discovery of large quantities of curleyleaf pondweed in the harbor and waterways that surround it. A survey funded through Lake County, the Flathead Lakers and the Department of Natural Resources and Conservation, and led by Eric Hanson of the Flathead Aquatic Invasive Species group found no traces of watermilfoil.

But, Hanson said the survey results showed a different aquatic invasive species, curleyleaf pondweed, has heavily infested (40 percent of the plants) the Eagle Bend harbor and channel. It was also found in patches along the Flathead River bottom leading upstream for a couple of miles, in Fennon Slough and in two places in Flathead Lake—just outside of the harbor in Somers and along a seawall outside of Bigfork.

Monster weed threatens Finger Lakes

New York — Advocates are warning the Finger Lakes and other upstate water bodies lakes could be overrun by a hyper-aggressive invasive plant unless more money is found for a major eradication effort.

The plant, hydrilla, was found late last summer in two creeks at the south end of Cayuga Lake at Ithaca. An initial effort last fall to control it failed to beat it back.
