31 May 2017 update on foamy bark canker
Here is a followup on Cooper1 and Cooper2 trees in Greenhorn Creek. We see some interesting changes. The Cooper1 tree, despite its decline is showing regrowth from the base. The third picture shows Cooper2, at the location of the branch with foamy bark canker, and it is showing good growth. Cooper2, in general, continues to decline, as does the adjacent oak, which we have not yet investigated.
See this for photo comparisons.

The Cooper1 tree is showing regrowth from the base.
Another image showing regrowth on Cooper1. Despite the death of the main part of the tree, there is new growth coming from the base.
New growth near the location of the branch on Cooper2 that was foaming.
Cooper2 tree is more dead that it was in October 2016. Notice the adjacent oak, whose canopy is in contact, is also dying.
Cooper2 tree is more dead that it was in October 2016. Notice the adjacent oak, whose canopy is in contact, is showing greater dieback than in October 2016.
Focus on the oak adjacent to Cooper2 (the tree going diagonally across the image). The dying areas are expanding.
