A historic die-off of fir trees occurred in drought-stricken Oregonbpnl eaving patches of red, dead trees on hillsides that were once covered in green conifers.
Researchers began referring to the affected regions as firmageddon when they passed overhead during airborne surveys that determined the size of the die-off since the damage to fir trees was so severe.

The surveyors ultimately tallied approximately 1.1 million acres of Oregon woodland with dead firs, the highest damage documented in a single season since surveys began 75 years ago, as per NBCNews.
The drought-related landscape changes in Western states that have been experiencing extreme heat are vividly illustrated by the dead fir trees in Oregon.
Future extinction of these fires could alter the character and function of many ecosystems by displacing them with drought-resistant species in many locations.
On the eastern side of the Cascade Mountains before it tucks into the high desert, Oregon is notable for its towering volcanic domes covered in a blanket of conifers that becomes patchy and sparse.
The most obvious dead conifers are those that are completely red or orange, but in some places, observers can also identify dead trees by their lack of needles.
The researchers were astounded by the extent of the devastation in Oregon, which was initially documented by the nonprofit environmental journalism organization Columbia Insight.
This situation screams for a more in-depth investigation.
Trees are vulnerable to defoliators like caterpillars, bark beetles, and root diseases.
Aerial surveys enable researchers to catch the booms and busts of these infections.
According to Kohler, when beetles bore into a tree's bark, for instance, a healthy tree can drive the beetles out by ejecting pitch, a gooey substance, at the point of entry.
However, adversities like wildfires, droughts, and windstorms can strain on trees and erode their defenses.
Massive groups of dead and dying trees might bark beetles to lay eggs, feed their larvae and flourish.
It plays a significant role in shaping ecosystems by functioning as an agent of regeneration and transformation, as per USDA.
But the fire may be fatal, burning homes, wildlife habitats and wood, and contaminating the air with pollutants dangerous to human health.
Climate change is leading to higher risk and intensity of wildfires in the Western United States.
Wildfire risk depends on intricate connections between temperature, soil moisture, and the presence of trees, bushes, and other potential fuels.
All these factors have substantial direct or indirect linkages with climatic variability and climate change.
Station scientists have shown that climate change raises the risk of major wildfires in the United States.
Wind and weather have repercussions on the ignition, behavior, and control of wildland fires.
Station scientists research the complicated meteorology climate and weather of a region connected with wildland fires, along with how weather conditions generate major wildfires.
The deep woods of the western Cascade Range in Oregon and Washington are recognized for their evergreen, rainy weather and infrequent wildfires.
As the climate becomes warmer and drier, west-side forests are seeing longer fire seasons, greater burns, and increasing wildfire risk.
