Sometimes this color is from deciduous leaves preparing to drop from trees like California buckeye and black oak, however this year there is significantly more brown on the hillsides. As you drive up to the school you see that the brown color is from ponderosa pine trees that have died over this summer. How did this happen? What can be done about it? Is this a fire risk?
After four successive years of drought, these trees have suffered and have been unable to respond normally to environmental stresses. One thing that can stress the trees are bark beetles. These insects lay eggs underneath the bark and the larvae feed on the wood. A healthy tree responds to a bark beetle attack by filling the hole with a thick, sticky, fluid called pitch.

The story describes the wolf reintroduction program, the rise in wolf population numbers and the ecological balance that returns. The story is useful in explaining the role of apex predators,…
