My research explores the management options for regenerating, restoring, and managing forests and landscapes in the Pacific Northwest and Alaska and the consequences of fire and fire surrogates treatments for fuel reduction and forest restoration in fire-prone forests throughout the United States.
Application of ecosystem and plant community classifications; silvicultural practices for regeneration and culture of boreal and Pacific Northwest conifers and hardwoods; plant competition and competion effects on tree growth; disturbance ecology and the role of natural and human-caused disturbances.
In one past study, I conducted a detailed examination of stand structure in old-growth ponderosa pine forests at three protected study areas in Oregon and northern California. I measured the spatial distribution, size, and age of live and dead trees in the area and assessed the condition of their coarse woody debris. Nearly all of the structure and distribution of old-growth ponderosa pine forests have been lost during the past 100 years because of harvesting, fire, and forest fragmentation. Thus, my findings provide a reference point against which managers can evaluate different structural trajectories within ponderosa pine ecosystems and gauge the success of restoration treatments.
