Invasive Species
In our world of globalization, many non-native species of plants, fish and insects have found new homes in and around Wisconsin.  Some of these species are extremely invasive, aggressively competing with our native creatures and their habitat.

It is important  that we remain diligent and watchful for invasive species.  The key to minimizing their impact is early identification.  Many of the lakes around us have already been infested by these invasive plants.

What can you do?

  • Clean off all weeds and empty lake water from your boat immediately after leaving a lake.  Never put your boat into a lake if you have weeds on it.  Even a small piece of a plant is enough to infest a lake.
     
  • Don't transport firewood out of the area where it was cut or bought. The Emerald Ash Borers main method of transportation is infested firewood.
     
  •  Never cut, mow or weed whip Purple Loosestrife.  It only spreads it.
     
  • Look over the invasive species below.  Keep your eyes open when you are fishing, swimming, boating, walking, etc.  If you think you have spotted an invasive species be sure to mark the location.  If feasible,
    take a sample.  Contact Don Dalton, Dave Hansen or Dick Hansen.  Or,
    you can email us here at info@porterslake.org.

Below is information on just a few of the invasive species for which we want to be most watchful.
