Missouri To Ban Felt in 2012

   The Missouri Conservation Commission has approved a regulation change banning the use of “porous-soled waders or footwear incorporating or having attached a porous sole of felted, matted, or woven fibrous material when fishing in trout parks and other specific trout waters. Pending public comment through the Secretary of State’s office, the new regulation will go into effect March 1, 2012, the opening day of catch-and-keep fishing at Missouri’s four trout parks.” 

   The move to ban felt in Missouri is not a surprise as we have been reporting that the rule was in preparation for nearly a year. The intent of the rule is to reduce the spread of Didymo, the invasive algae that has rapidly spread across the Eastern US. Tim Banek, invasive species coordinator for the Missouri Department of Conservation, said Didymo has prompted his agency to begin developing the regulations.  Read More

  While Missouri is the latest state to institute a felt ban, we can expect that other states and jurisdictions will be considering felt bans as well. We will continue to provide a comprehensive accounting of all felt ban proposals in the US at US Felt Bans

Ballast Water Remains a Threat

   Ballast water continues to be the biggest problem for new international aquatic invasions. New York is set to implement strict regulations on ballast water but the move is strongly opposed by many. Perhaps most critically, the US House of Representatives is quickly working on a bill that would prevent the New York Regulations from taking effect.  Read More

    While ballast water regulations are being hotly debated, the shipping industry has weighed in with the threat that hundreds of thousands of jobs may be at risk. Pointing at the economic advantages of not regulating ballast water the industry group tries to make a case that preventing invasive species is too costly. Read More

Federal Response to 9/11 Benefited Invasive Species

  According to a newly released AP report, “Dozens of foreign insects and plant diseases slipped undetected into the United States in the years after 9/11, when authorities were so focused on preventing another attack that they overlooked a pest explosion that threatened the quality of the nation’s food supply.
     At the time, hundreds of agricultural scientists responsible for stopping invasive species at the border were reassigned to anti-terrorism duties in the newly formed Homeland Security Department — a move that scientists say cost billions of dollars in crop damage and eradication efforts from California vineyards to Florida citrus groves.
      The consequences come home to consumers in the form of higher grocery prices, substandard produce and the risk of environmental damage from chemicals needed to combat the pests.”  Read More

Asian Carp Stories of Interest
     The potential invasion of the Great Lakes bu Asian carp remains the big story. There continues to be action on the legal and legislative front while powers battle of their own interests. Here are some stories of interest.

   The fight to close off the potential pathway between the Great Lakes and the Mississippi took a new turn in October when five states asked the U.S. Supreme Court to hear their plea for quicker federal action to prevent Asian carp and other invasive species from moving between the watersheds.  Read More

    While the legal fight continues, in a Purdue University Calumet classroom representatives of Great Lakes protection and advocacy groups revealed preliminary concepts to protect the world’s largest surface freshwater source from Asian carp and other aquatic invaders.  Finding a cost-effective way to separate the Great Lakes and Mississippi River watersheds to combat invasive species may be a Herculean task. And it appears potential solutions will be a tough sell.  Read More

   Not everyone is convinced that Asian carp would actually cause problems in the Great Lakes, including some noted scientists. For a good overview of  both sides of this argument listen to this Podcast from Ann Arbor Science & Skeptics. In it, Dr. Gerald Smith, professor emeritus at the University of Michigan argues that the carp represent far less of a threat than believed while Dr. Michael Murray, staff scientist with the National Wildlife Federation of Michigan presents the case that the carp are a serious ecological threat.Listen Here
