Most all of our pine and pinon trees survived the Little Bear Fire in 2013, but we didn't realize that many of them had been weakened by the fire. Then we discovered, starting in 2014 and several years after, that pine bark beetles were attacking the weakened trees and killing them. So we lost many trees to the beetles. All you can do is cut them down and burn all the wood in burn piles. Some folks would cut up the trees for firewood, but that only transported the beetles to other areas! There are different species, but our NM adult ones were oblong shaped and black, like this, only larger (30 mm?):

The good news was that our juniper trees were virtually indestructible. We found that even blackened stumps had new growth coming up from the roots the following year.
