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. Learn more at dontmovefirewood.org

#FirewoodMonth continues with a webinar tomorrow (Oct. 28, 4 p.m. EST) on the goldspotted oak borer and its spread through firewood. Presented by Joelene Tamm, Natural Resources Director for the LA Jolla Band of Luiseño Indians.

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.

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

OCTOBER IS FIREWOOD MONTH. 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. TRANSPORTING FIREWOOD CAN SPREAD PESTS: Trees in ALL 50 STATES AND 10 CANADIAN PROVINCES ARE AT RISK of attack by invasive species if people move infested or diseased firewood.

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.

Ash Tree Identification Use this guide to properly identify ash trees. Tree species resembling ash are also included.

Knowing your ash trees is the first step in protecting them from #EmeraldAshBorer. MSU Extension’s guide shows how to tell true ash apart from lookalikes like elm, boxelder and walnut.

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.

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 🧪🌍🍁

Be an EcoScout: Spot it, Stop it! Keep a sharp eye out for invasive species. Note key ID traits to confirm what you've found. If you've checked the ID and think it's invasive, report it to your local Extension office or state forestry/natural resources department. Your reports help stop or slow the spread of destructive invasive insects.

Become an #EcoScout in your own community. "Spot It, Stop It" is your guide to identifying and reporting invasive insects.
