Climate change is a disaster of epic proportions
Impacts to our iconic forests include reduced
snowpack, increase wildfire, species shifts, and
change in carbon balance
Our forests are being over-harvested, contributing
to the problem
There is great opportunity to make forests part of
the solution
These include increasing the forested area through
reduced harvest, and increasing forest stability
through partial cutting and increased planting of
resilient mixtures
