A close look at this fallen spruce tree raises questions underlying causes and tree health.

The invasive orange hawkweed, known for its striking appearance, is rapidly spreading across Southeast Alaska, threatening local ecosystems by outcompeting native plants.

"This season we have observed many salmonberry bushes that appear to be defoliated. It seems something is eating the leaves. We have also noticed the berries look sickly."

Scientists with the U.S. Forest Service believe that the blackheaded budworm, whose numbers surged over the past three years, is now in decline.

Foam or saliva-looking substance on seen on flowering plants like fireweed and yarrow.

Last summer’s unusually warm weather fueled an explosion in the western blackheaded budworm, leaving masses of browning trees in many areas of Southeast. The worm, which is the larval stage of the budworm moth, is known to feed on the new growth of trees, leaving them with a brownish-red appearance.

A resident of Seldovia reported an infestation of worms infesting an area of salmonberry brush and nettle.

Hikers on Kesugi Ridge observe a large abundance of Rusty Tussock Caterpillars all over cairns marking the trail from Coal Creek to Byre's Lake. They swarmed on the hiker's bodies and packs and from a distance covered structures to the point where they looked black.

Climate change is keeping temperatures higher in the fall, setting up browntail-moth caterpillars to boom in summer. Their hairs are barbed and hollow and there’s a reservoir of a toxin inside.

Lymantria dispar dispar also known as spongy moth was observed in Waterloo Ontario to be in unusually large quantities during the summer of 2021.

The worst Gypsy moth caterpillar outbreak in Eastern Ontario in 30 years is ripping through city backyard trees and rural forests at an alarming rate.Some pockets of forest north of Belleville, along Highway 7, look like stands of giant toothpicks after being picked clean of their foliage.

That includes the trail at the south end of Wrigley Lake in North Dumfries

Defoliation of willows, alders, and berry bushes may be related to different insect species depending on the plant.

If you hear the pitter-patter of what sounds like light rainfall but can't feel a drop of water, you probably already know that you have a caterpillar problem.

"Throughout Viken in the lowlands there is an increasing evidence of spruce bark beetles and that is worrying. What is positive is that in Measure Package No 2 from the Government you receive financial compensation for wind fall logging and forest management" says Lars Kr.

A prolonged heatwave in Siberia is “undoubtedly alarming”, climate scientists have said. The freak temperatures have been linked to wildfires, a huge oil spill and a plague of tree-eating moths.
