After a yearslong California drought, an "unprecedented" number of trees are dead up and down the coastal state.
And that poses a huge threat to local communities.
It's estimated 36 million trees have died since May, which would put the total number of dead trees in the state at more than 102 million.
A majority of the dead trees are in the Sierra Nevada region, but they've also been found in northern California.
Authorities are predicting the die-off will last at least another couple of years. Even if California got an unusually high amount of precipitation, it wouldn't do much to curb the damage for some time.
