Why This Research is Important

  • Modifications of theory and practice of silvicultural systems under the influence of changing climate
  • Continue to advance the theory and practice of uneven-aged silvicultural systems in intolerant southern pines based on long-term experience
  • Advances in silvicultural theory and practice are needed to restore mature fire-adapted southern pine forest ecosystems in the Southern US that are underrepresented opn the landscape, including longleaf pine on the lower Atlantic and Guld Coastal Plain, mixed loblolly-shortleaf pine stands on the upper west Gulf Coastal Plain, pure shortleaf pine-dominated forest ecosystems in the Ouacahita and Ozark Mountains, and mixed shortleaf pine and pine-oak ecosystems in upands forests east of the Mississippi River
  • Advanced technical skills are needed for silvicultural certification required by law for foresters practicing on National Forest lands
  • Improve models for growth and yield of even-aged southern pine stands in the Ouachita Mountains
  • Develop indicators of long-term sustainability in applied forest management for ecological restoration goals in shortleaf pine-dominated ecosystems in the Ouachita Mountains

Guldin is one of three permanent members of the SRS Research Advisory Board (RAB), which provides oversight and programmatic direction of the Station’s research program in collaboration and with concurrence of the Director. As member of the RAB, Guldin serves on the SRS Executive Board (EB, which provides support and advisement to the Station Director on decisions related to budget and hiring priorities, personnel actions, facilities, and research organization of the Station. As Station Silviculturist, Guldin plans, conducts, and administers research on silvicultural systems in southern pines, with an emphasis on even-aged and uneven-aged reproduction cutting methods that rely on natural regeneration at the stand and landscape scale. The scientist is responsible for active studies and demonstrations in four different forest types in the Mid-South: the Upper West Gulf Coastal Plain mixed loblolly-shortleaf pine stands in south Arkansas, pure shortleaf pine and pine-hardwood stands in the Ouachita Mountains and Ozark Highlands of Arkansas and Oklahoma, longleaf pine forests in the Lower Gulf Coastal Plain of Alabama and Louisiana, and oak-hickory hardwood-dominated stands in the Ozark Highlands.
