2017 Whitefish Invasive Plant Survey

EDITORS NOTE December 2017:

 Thanks again to Marv Erdman, WAPOA Emeritus Director, for again organizing these inspections for invasive species. 

Good News!   No new invasive plants were found in an inspection of lake locations done in  July and  September 2017.   Many of the inspections were on the Whitefish Chain, usually around high risk areas like boat accesses.  No Eurasian watermilfoil was found. No starry stonewort was found  .… LINK HERE

WAPOA pays for Professional Lake Management to do the inspections annually in July and again in September—the time most likely to find Eurasian watermilfoil and starry stonewort.


What should we do if we find a new invasive plant in our lake?

WAPOA feels the best chance of eliminating or controlling an invader is by immediately taking action when it is still limited to a small area.

To get early detection,  WAPOA, in cooperation with several lake associations, pays for plant professionals to search for invasive plants in about 30 lakes in our area.

July/September survey of the Whitefish Chain looking for invasive plants.

They also surveyed other participating area lakes and found only curly leaf pondweed and purple loosestrife.
