Bigger and hotter wildfires continue to sweep through forests that have not evolved to survive such high-intensity blazes and a warmer climate. This has created a permanent shift from large beautiful pine trees to an entirely new ecosystem of shrubland in the Western conifer forests. As these burnt areas cause trees to disappear, the areas will become hotter, winter and spring snow will melt faster, and this will affect surrounding wildlife and communities that are already struggling with water shortages.
Dr. Johan Eckdahl, a postdoctoral researcher at Energy and Resources Group at UC Berkeley, conducted research this month along with Dr. Winslow Hansen in the Sierra Nevada to study these effects. On a burned hillside area of 100 feet, they recorded each flowering plant and shrub, filled plastic bags with soil, and used a probe to record the ground moisture and temperature.
“We haven’t found one ponderosa seedling,” Dr. Hansen said. Ponderosa seeds are known to adapt to fire and warm climates. But even these high-intensity fires are just too hot for them.
