An overview of the state of Colorado's forests, presented to the Colorado legislature in April 2017.

f we use insect and disease attacks as indicators of genetic simplicity, and resilience to these pests as indicators of genetic robustness, we can use harvesting to assist natural selection to build a more resilient forest ecosystem with a greater ability to survive climate fluctuations and associated perturbations. This may mean changing certain silvicultural paradigms and not selecting for the fastest growing or tallest trees - but intermediate sized trees that use their energy reserves for defense and water conservation as well as growth.
