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.
