Current Research

My current research emphasis is on the oak regeneration problem. I am responsible for five separate studies. They are:

  1. root development of oak seedlings growing in shelterwood stands,
  2. esponse of mountain laurel to chemical, cultural, and mechanical control practices,
  3. uantifying fuel loadings and fire behavior in oak forests,
  4. esponse of northern red oak seedlings to forest liming, and
  5. dendroecology of xeric oak – pine forests.

Research Interests

Given the intractable nature of the oak regeneration problem, I?ll likely be engaged in oak research for quite some time.

Why This Research is Important

Oak forests are the dominant forest type in much of the eastern United States yet they face a myriad of problems that prevent their regeneration. My research addresses several of those regeneration obstacles and my results help foresters be better stewards of oak forests

Research Highlights

Changes in Black Cherry on the Allegheny Plateau (2016)
NRS-2016-130 Increased tree mortality, decreased seed production, and seedling growth. Managers and scientists have been observing these changes in black cherry on the Allegheny Plateau and are working together to sharpen the research focus and utilize long-term research to improve forest management.

Fire Returns to the Allegheny National Forest, and Oak and Black Cherry Thrive (2020)
NRS-2020-74 After a century of absence from the Allegheny Plateau of northwestern Pennsylvania, prescribed fire has been reintroduced as a means of perpetuating the mixed-oak forests of the Allegheny National Forest.

How not to kill mountain laurel (2017)
NRS-2017-81 Sometimes failure can be as important as success when it comes to developing appropriate silvicultural treatments for controlling interfering understory vegetation. A Forest Service scientist succeeded in establishing that seven common treatments do not work when it comes to controlling mountain laurel, a pervasive problem in eastern forests.

Understanding Mountain Laurel’s Impact on Oak Regeneration (2016)
NRS-2016-166 When did the dense understories of mountain laurel seen in some mixed-oak forests become established, and why? How dense does mountain laurel have to be to interfere with oak regeneration?
