This summer has been marked by heavy rain and even flooding in many parts of the United States. Drought, however, continues to plague large sections of the country.
According to the latest report from the U.S. Drought Monitor, 41% of the nation is in some form of drought. Many areas in the south and northeast are listed as abnormally dry or experiencing moderate drought. But, it is the western states that have been particularly parched.
One of the hardest hit states is California, which is now in its fifth consecutive year of drought. In fact, 100% of the Golden State is currently experiencing some form of drought with 43% in extreme drought. These exceptionally dry conditions have provided the fuel for an early and explosive start to the region’s wildfire season.
Deprived of water, trees in California have not been able to produce the sap that helps protect them from insect infestations. This has left them vulnerable to attack by bark beetles, especially as the temperature warms. Together, the drought and these insatiable insects have increased the rate of tree mortality in the state over the past few years. According to a recent survey by the U.S. Forest Service, 66 million trees have died in the Sierra region of California since 2010. That is an increase of 26 million since the last count in October. Sadly, as the drought continues, more trees are expected to die, further elevating the risk wildfires.
