Current Research

I am the manager for the long-term mensuration research studies in Arizona, Colorado, South Dakota, and Wyoming. I maintain databases associated with mensuration studies and assists in silvicultural research. I am certified as a Region 2 Silviculturist.

Current Silviculture Research I am working on:

  • Developing, implementing, and evaluating the irregular uneven-aged silvicultural system as a viable method for creating resilient forests.
  • Identifying spatial explicit reference conditions for ponderosa pine and dry mixed conifer forests of the Colorado Front Range and the Black Hills for restoration prescription development
  • Assessing spatially heterogeneous forest structure impact on fire behavior
  • Characterizing patterns of tree regeneration following large wildfire
  • Utilizing long-term growth studies to validate and calibrate the Forest Vegetation Simulator
