Aleppo Pine probably
One of the smaller trees.
One branch died off but it didn't seem to spread to the the rest of the tree.
On 9 Jul 2018, I went to check on the pine tree. As I approached it, I saw a lot of other debris piled up there (manzanita branches, I think) and no pine. And as I got next to the pine, I saw that it was on the ground and all brown.
But it wasn't that it had been crushed by the other debris--it had been sawn off at the ground! I was so mad! The little pine is not native to here, but then, a whole lot of the other plants are not native either! Grrrrrr!
