    Very interesting Research by UW-Student.

    Are zebra mussels unfairly shelled? Student’s research suggests so

    Meder, who teamed up with UW Oshkosh College of Business Economics Professor Marianne Johnson, launched his deep dive into the data of zebra mussels in 2012. After spending hundreds of hours analyzing Integrated Property Assessment System (IPAS) data from the state for properties on more than 400 lakes in 17 northern and northeastern Wisconsin counties, Meder reached a conclusion.

    … And probably not the one you’d expect.

    “If there is an impact, it’s clearly not negative,” Meder said. “We find that property values generally are higher on lakes with zebra mussels.”

    Higher? With zebra mussels? The aquatic invader Wisconsin has learned to loathe?

    “Some research has shown that they disadvantaged some unpopular fish species,” Meder said. “They blanket the bottom of the lake bed so carp can’t feed… If they can’t get past zebra mussels, they can’t eat. So, they are disadvantageous for carp. They also seem to be advantageous to fish species that people like, like smallmouth bass. They tend to help those populations out a fair amount. They increase the water clarity of the lake, and they remove pollutants that are suspended in the water at an increased rate… which makes lakes safer to swim in if they weren’t previously.”

    Meder said his research doesn’t address the causation, but “with statistical certainty, I can say that zebra mussels are associated with an approximately 10 percent increase in lakefront property prices.”

    Just some snippets from article, but very interesting, enough to get me to read the whole thing.

    Like most things in life. There are both good and bad in most everything.

    what was the increase in value of lakes that aren’t infested? what would the increase in value have been had the selected lakes not been infected?

    Don’t get me wrong, it is impressive work by an undergraduate. However, it is so limited in what it says about the zebra-value relationship it is useless to inform policy.

    As a Great Lakes fishing Guide I am always concerned when we here about another invasive specie entering the lakes and its impact on the lake and more importantly the fish species that live here. Since the invasion of the zebra mussel we have not seen any substantial negative affect on our Smallmouth Bass or our Walleye populations. We have seen changes in the system that have affeted the Lake Whitefish and the main forage that they used to primarily feed on but they have been able to adapt and what they now are feeding primarily on is another invasive that came after the zebra mussel which is the Round Goby. So yes there are changes that occur when invasives enter a new body of water but they are not always bad and usually we do not see there impact whether it is negative or positive till some time down the road.

    X2. A good start in a new way to look at em.

    That is until you slice your feet open on the clusters of zeebs.

    That’s why people swim on sandy beaches.

    There was a similar study back in the 70’s about steel beer cans on the bottom of a lake…. evidently, the more Schmidt cans, the higher the DUI rate near that lake….

    Yes, this was sent to Joe.

    The Chanhassen Villager (Newspaper) included a posting of this on their Facebook page yesterday.

    The “Minnesota Association Of Watershed Districts” “AIS Symposium” scheduled for next Wednesday at the Capitol should be interesting.

    I’m attending just to be able to report what is going on and stay ahead of the curve to fight stupid Rules!

    I’d probably end up in jail if I attended. I cannot tolerate people who choose to be ignorant and ignore all logic.

    Darn glad there are others out there who can attend these meetings with a little more composure.

    I agree 100%. It is a correlation not cause. A 3rd grader could have safely assumed once Gull and Minnetonka had zeebs, that property values on lakes with zeebs are higher…. That hardly makes zeebs a good thing.

    Hence my beer can relation…. the “lake” did not make them drink

    I submitted this to KARE11. We’ll see if they follow up.

    Interesting. Don’t want zm in the lake but this does kind of shoot the argument zm will “decreae our property values”

    Still doesn’t affect the I want to control my lake or keep others out argument.

    As others already pointed out you need to prove a cause and effect… you can’t publish a correlation study and use it as proof of the theory…

    Logic has already been spelled out fairly clearly why the results may be the way they are.

    You can’t compare the two populations of lakes (those with and those without ZM) The two population of lakes are very very different. For instance which lake is more likely to have ZM… the local swamp with terrible land value and that nobody uses as a recreational lake or a highly popular large body of water with lots of fish and boating opportunities?
