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

National Research Highlights

A mixed-oak forest with a dense understory of mountain laurel in eastern Pennsylvania. Note the 8-foot range pole in the center of the photograph. Recent research shows that when mountain laurel cover exceeds 25 percent, regenerating oaks becomes extremely difficult. Pat Brose, U.S. Department of Agriculture Forest Service.

Understanding Mountain Laurel’s Impact on Oak Regeneration

Year: 2016

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?

This black cherry seedling is infected with black cherry leaf spot. Managers and scientists have observed this infection more frequently in recent years. Robert Long, U.S. Department of Agriculture Forest Service.

Changes in Black Cherry on the Allegheny Plateau

Year: 2016

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.
