Current research projects focus on determining the effects of alternative silvicultural treatments on stand structure, composition, and development over time, particularly for stands with multiple-use or restoration management objectives. In addition, Knapp is interested in contrasting traditional silvicultural practices with those that emulate natural disturbances and determining the effects of disturbance events, both natural and anthropogenic, on regeneration dynamics. His work integrates ecological theory with silvicultural application to better address a wide variety of management challenges and needs.
