Oregon Conifers Suffer Record Die-Off As Climate Crisis Hits Hard

An anonymous reader quotes a report from The Guardian: Scientists have discovered a record number of dead fir trees in Oregon, in a foreboding sign of how drought and the climate crisis are ravaging the American west. A recent arial survey found that more than a million acres of forest contain trees that have succumbed to stressors exacerbated by a multi-year drought. Images released by the US forest service show Oregon's lush green expanses dotted with ominous swathes of red. "It is stunning," said Daniel DePinte, an aerial survey program manager with the Forest Service who led the agency's Pacific north-west region aerial survey, noting that this year saw the highest mortality rate for firs in this area in history. These evergreen conifers are less able to survive in drought conditions than other heartier trees that line the landscapes. He and his colleagues scanned the slopes from planes several times between June and October, detailing the devastation on digital maps. During that time, it became clear that this year would be unlike anything he had seen before. The report is still being finalized but dead trees were spotted in areas across 1.1m acres of Oregon forest. The scientists have taken to dubbing it "firmageddon." "The size of this is enormous," DePinte said. "A lot of people out there think climate change is just impacting the ice caps or some low-level island out there but it is actually impacting right here in our backyard," he added. "If this drought continues as climate change keeps on, and we continue ignoring what nature is showing us across the globe - it doesn't bode well at all." "It will be a different forest with a different feel and it will happen across the landscape as nature decides," DePinte said. "Nature is saying there is just not enough to support the firs, and they will overtime be eliminated from those areas." "Scientists have expected to see signs of stress in the forests, but the suddenness of the spike in mortality was alarming," adds the report. "Before this year, the largest area where dead trees was recorded in Oregon was in 1952 where die-offs were spotted across roughly 550,000 acres." "The flood of warmth and light once guarded by a thick canopy can increase stream temperatures or make space for invasive species once kept out by shade. Some species will thrive in the shift. But others will perish." The tree deaths also heighten the risk of wildfires.
