Alaska’s Spruce Beetle Epidemic

Alaska’s forests have been waging a losing war against tree-killing spruce beetles for the sixth year in a row. Over 1.1 million acres of wooded area have been impacted by the spruce beetle in Alaska’s south central regions alone since 2015, with thirty thousand of those acres lying within the bounds of the Anchorage Municipality, according to the Alaska Division of Forestry.

Extreme Heat, Dry Summers Main Cause of Tree Death in Colorado’s Subalpine Forests

Even in the absence of bark beetle outbreaks and wildfire, trees in Colorado subalpine forests are dying at increasing rates from warmer and drier summer conditions, found recent CU Boulder research. The study, published in February in the Journal of Ecology, also found that this trend is increasing. In fact,...

Forest Service Removes Sun Valley Trees In Race Against Bark Beetle

Bald Mountain is the economic driver for the Wood River Valley, drawing more than 400,000 skiers each year to Sun Valley. But forest managers say the health of the mountain’s trees is at risk. Last year, the U.S. Forest Service finalized a plan to treat more than 6,000 diseased and...

Trees killed by bark beetles helping fuel wildfires

Fire managers on the Bootleg Fire have mentioned beetle killed timber as one of their concerns as crews work to contain the massive wildfire in Southern Oregon. Trees killed by bark beetles are helping fuel the fire. “What happens is these infestations of beetles, the beetles go in, and if...

Generated furniture: cursed, but beautiful

Beetle kill pine is a popular wood in Colorado, salvaged from trees killed by pine bark beetles. While the dead trees stand before harvesting, a fungus colonizes them, giving the wood interesting blue-grey streaks called spalting. It’s a really pretty wood. But AI apparently thinks “a chair made of beetle...

Eastern Hercules Beetles

The eastern Hercules beetle is one of the largest and heaviest insects in the U.S. In South Carolina, there is only one Hercules beetle species, Dynastes tityus. These insects are a type of beetle in the family Scarabaeidae – the same family as June beetles, Japanese beetles, and dung beetles.

Bark Beetle Outbreaks Adding To Fire Risk

The situation is putting federal forest officials behind the curve. “Instead of the Forest Service being able to get ahead of an area that hasn't burned and get it down to a density or a species composition that would be resistant to the next wildfire, we have so many wildfires that we end up putting all of our efforts into after the fire has started,” says Todd Hamilton, a silviculturist with the Shasta-Trinity National Forest. “It's tough to put the effort in up front to get a forest into a condition that is less vulnerable to wildfires, bark beetles, drought and so forth.”

Ash trees under attack

Once you know how to spot it, you can’t miss it. Nearly all of the area’s ash trees are being eaten, from the inside out, by an invasive green beetle. The beetle, called the emerald ash borer, was first detected in the Great Lakes region in 2002. An invader from Asia, the beetle has since chewed its way through hundreds of millions of ash trees, south, east, and west. It landed in Casey County in 2016, and is now going through the ash trees here.

White grass a rare yard malady

State asking landowners to help mitigate Engraver Beetle population increase

PIERRE, S.D. — Ips Engraver Beetle numbers are increasing after taking advantage of trees damaged in the Custer tornado earlier this spring. State Forestry is now asking landowners to help control the population before the beetles move to live trees. The Engraver beetles are bark beetles capable of producing two-...

Bugs, bugs and more bugs

CHARLOTTE, N.C. — The charlotte canopy is lush and beautiful but also food for a number of invasive bugs. These bugs have a voracious appetite and will and can destroy trees and plants in no time. What can we do to combat the insect problem? City Arborist, Laurie Reid says...

Pine Engraver Beetles Profit from Tornado-Toppled Trees Around Custer

A tornado knocked down trees near Custer in May. Now those downed trees are feeding pine engraver beetles:. “The downed trees are quickly becoming infested with the engraver beetles” says Greg Josten, South Dakota State Forester. “Once the beetle raises a new generation inside this fallen material, the new adult beetles will leave this wood and may attack standing live trees.”

Forest Health and the Effects of Drought

As someone who has studied forest health for a while, I have developed the rather unfortunate habit of noticing only the red and brown canopies that appear in a sea of green (my wife says it makes visiting the forest with me rather depressing). Unfortunately, the tell-tale sign that a tree just died has become a common sight in the coastal forests over the past few years. While there is a suite of forest health issues (invasive species, fire suppression, and climate change to name a few) that are likely driving this decline and dieback, there is one that I am currently most concerned about: Drought.
