Milfoil on Rush last year  (click here for pdf with pictures)

Milfoil on Rush 2016  (2016 survey report)   (2016 Hand Pulling Report)

From the surveys we identified the GPS location of plants.
Divers from Waterfront Restoration hand pulled Johnson's site 2-6 on August 10th 2016. There were more plants than expected but all of Johnson's GPS marking plant got pulled. Two of the sites that had more plants then expected were marked and rechecked the following day where several more plants were found.
The chemical treatment was delayed because the EWM might not be that susceptible to the herbicide right now but will be during the fall growth spurt. 

Please learn about identification, prevention and treatment. We need everyone’s help.


Winter is the time to get the dead oak branches trimmed and removed.

We live in Oak Wilt territory and are in the highest danger season April, May and June for spreading Oak Wilt. While all species of oak can be affected, oaks in the red oak group (oaks with pointed lobes on their leaves) are by far the most susceptible and are probably the most abundant tree in our yards. Northern red and pin oaks can die within two to three months of infection. White oaks are the most resistant and may survive for years after infection. Bur oaks are intermediate and may die within two to three years of infection.

Emerald Ash Borer (EAB) has killed millions of ash trees since 2002.

Minnesota currently has the largest Ash tree population in the United States. 
Don’t move firewood to or from your lake home from long distances.

(You typically can’t see if firewood is infested or not, so why take the risk?)

It is that time of year when we need to be on the lookout for woodpeckers in ash trees!
Emerald Ash Borer is on its destructive path (CLICK HERE FOR KARE 11 STORY) 
It is spreading too!  Now only 6.5 miles east and southeast of Elk River:  (CLICK HERE FOR MAP) 
Early detection is critical to minimizing tree loss and the subsequent loss of environmental benefits.
