The report this week that a third year of the branch sampling program for Emerald Ash Borer showed no further evidence of the EAB in the city at this time is certainly good news, if for no other reason than we all have more time to act. But act we must.

Emerald Ash Borer was confirmed in Madison in November of last year. With an estimated 21-thousand publicly owned ash trees on street terraces, who knows how many in city parks and thousands on private property the threat is real.

EAB is an invasive pest and it’ll kill a lot of trees before it’s done. So while the slow spread is good news we have to do everything we can to prevent its growth.

The city plan is in full swing. Advice for homeowners is available on the city website. We urge you to visit the site and call a certified arborist if necessary.

Losing hundreds or thousands of ash trees in our beautiful city will not be a pretty picture.
