Invasive species are a significant threat to biodiversity.

Invasive species pose a threat to surrounding wildlife, and as they are not native to the U.S., they can disrupt ecosystems and create much larger problems. Earlier this year, experts called for gardeners to pull out any garlic mustard, which is classified by the U.S. Department of Agriculture (USDA) as a "terrestrial invasive." This plant sprouts earlier than others around it and is then able to commandeer natural resources. It also blocks sunlight from other species and releases a chemical that kills integral underground fungi. But not all invasive species put down roots, and another kind of invader could be harming your trees.ae0fcc31ae342fd3a1346ebb1f342fcb

Holes in your hardwood trees could be a sign of something more serious.

If you notice perfectly round holes in the bark of your hardwoods, they might be playing host to a dangerous insect—the Asian Longhorned Beetle. The USDA classifies this bug as an invasive pest, posing the greatest threat to American hardwood trees. In fact, the agency warns that it could cause more damage to national forests and backyard trees than Dutch elm disease, chestnut blight, andgypsy moths combined.

Ayon kayCharles van Rees, PhD, conservation scientist, naturalist, and founder of the Gulo in Nature blog, this beetle has no native predators in the U.S., and domestic hardwood trees do not have any natural defenses. With no one to eat adult Asian Longhorned Beetles or their larvae, their populations easily multiply.

"As a result, our native forests, upon which both we and wildlife depend, become a smorgasbord that gets rapidly devoured," van Rees said. "The damage that their larvae do while feeding on the inner bark and heartwood of hardwood trees usually kills them."

The distinctive holes are how the beetles emerge from trees.

The punctures in the bark of your trees are actually the beetles' exit holes, according to the USDA, and they will be perfectly round and pencil-sized.

"This is where the larvae emerge once they have changed into adult beetles. Piles of fine sawdust around the base of trees is a good sign that the larvae are working within," van Rees said. He added that rounded depressions, also known as "wounds," are left by adult females when they bite into the tree bark to lay eggs. This will then leak sap, which is another telltale sign that your trees are in trouble.

The beetle itself has a distinct look you can spot.

According to the USDA, the Asian Longhorned Beetle is a threat to elm, birch, poplar, and other varieties of hardwoods, currently affecting areas in Massachusetts, New York, and Ohio. While this beetle has not yet been detected in Western states, all U.S. states are thought to be at risk, the agency says. Entomologists believe that the larvae originally arrived in the U.S. via wood products or crates from East Asia and then grew into adults in the states.

While the most obvious signs of the beetles are the larvae in your trees, you can also recognize the beetle itself, as it is quite distinct. They are anywhere between .75 and 1.5 inches in length, and have "bullet-shaped" shiny black bodies with white spots and long striped antennae. Van Rees pointed out that the beetles are also commonly referred to as "starry sky."

Pay attention to your trees if they seem stressed, van Rees said, which you will notice if leaves start falling off or changing from a green color to yellow.

"Keep a close eye on how 'perky' and alive your trees look as the spring progresses," he noted. "This time of year, they should be getting greener and healthier looking all the time."

Kailangan mong makipag -ugnay sa mga lokal na ahensya o ang USDA kung nakita mo ang mga palatandaang ito.

"Gusto nilang malaman na ang beetle ay nagpakita sa iyong pag -aari, dahil maingat nilang sinusubaybayan ang pagkalat at pag -unlad ng mga species na ito," sabi ni Van Rees. "TeleponoMga app tulad ng Eddmaps ay isang madaling paraan upang ipaalam sa kanila, ngunit kung nais mo ng tukoy na payo sa kung ano ang gagawin, pinakamahusay na tumawag o mag-e-mail ng isang tanggapan.

Inirerekomenda din ng ahensya ang sourcing na kahoy na panggatong sa lokal hangga't maaari, at hindi ilipat ito, dahil ang mga beetle ay maaaring makaligtas sa nakatago sa mga log na ito sa anumang yugto ng buhay.
