65% of people use firewood: 53% for home heating, 49% for recreation, and many for both. Transporting firewood can spread pests. Trees in all 50 states and 10 Canadian provinces are at risk of attack by an invasive species if people move infested or diseased firewood. Buy it where you burn it.

As leaves begin to fall, bark "blonding" becomes increasingly visible. Look for these marks from woodpeckers that often indicate the presence of #EmeraldAshBorer.

Learn more about woodpeckers and EAB biocontrol methods here: www.emeraldashborer.info/biological-c...
#InvasiveSpecies #Entomology 🧪🌍🍁
Signs of EAB: Woodpecker Activity. Native woodpeckers are the primary predators of emerald ash borer (EAB) in North America and are the most important source of EAB biological control. Patches of light-colored bark on upper portions of ash trees are likely locations where woodpeckers have recently peeled away bark to remove EAB larvae. "Blonding" is often the first evidence that EAB is present in a local area.

Think about it: the trees cut for firewood often die due to insects or disease. Don't spread pests – buy firewood where you burn it.

FIREWOOD ISN'T DEAD: When 1,045 pieces of firewood were studied in Michigan, scientists found live wood boring beetles in 23%-- and another 41% had evidence of previous infestation. 77% of Americans live less than 10 miles from a wooded area. JUST GET OUT AND WALK: Taking a walk creates a 12.4% drop in stress hormones, a 1.4% drop in blood pressure, and a 5.8% drop in heart rate. 92% of Americans have at least 1 tree on their property. 65% of people use firewood: 53% for home heating, 49% for recreation, and many for both.

Don’t confuse #TreeOfHeaven (Ailanthus altissima) with important native lookalikes like walnut or sumac. Tree of Heaven has smooth bark, smooth leaf edges with a single tooth at the base and gives off a strong odor. Learn more here: www.canr.msu.edu/resources/a-... #InvasiveSpecies #Entomology 🧪🌍🍁
Tree of Heaven: What to Look For. Pinnately compound leaves where small, pointed leaflets are attached to a central stalk. Bark is smooth and resembles elephant skin or cantaloupe skin. Leaflets are smooth and have a small glandular "tooth" at the base. Most notably, a strong odor --often compared to rancid peanut butter-- that researchers believe may attract Spotted Lanternfly.
