Conducting a survey for the emerald ash borer - the State of Wisconsin has hung a bunch of 12" x 24" triangular purple insect traps in ash trees along roadsides all over the peninsula.
The purple traps, which are sticky and baited with a compound that simulates a distressed ash tree, are designed to attract the destructive emerald ash borer, should it be present.
Every time I see a dead or failing ash tree I cringe. It's the dominant species around here.
God help us when the ash borer arrives.
