I conduct educational programs to a wide variety of audiences on reforestation, thinning, maintaining healthy forests, backyard woodlands, stand density management, fire and fire management and a variety of other topics. My areas of interest and research include: uneven-aged management of ponderosa pine and mixed conifer forests; fire ecology and fire management; prescribed burning; forest health and resiliency; post-fire regeneration; regeneration processes; and thinning methods.
