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

    Example of a forest structure suitable for northern goshawks and producing high quality timber
    Wildlife habitat and timber production are critical elements of the management of many National Forests. The Black Hills National Forest has provided a thriving timber economy for over 100 years. The forest also provides habitat for the northern goshawk, which has been severely impacted by mountain pine beetles. 
    Through fire management and riparian ecosystem restoration RMRS researchers Terrie Jain, Kate Dwire, and Travis Warziniack are partnering with the University of Idaho and the Idaho City Ranger District to develop, implement, and evaluate different adaptive management strategies to improve the fire resiliency of the Boise National Forest. 
    There is an urgent need to develop adaptive management strategies that foster ecosystem resilience to the impact of climate change and enable forests to adapt to uncertain future conditions. This project utilizes a scientist-land manager partnership to develop, implement, and measure ecological responses in a large-scale replicated study of three adaptive management treatments strategies in the dry mixed conifer forest type.
    The development of ecological restoration treatment prescriptions based on historical forest structure is needed to inform management activities within the Collaborative Forest Landscape Restoration (CFLR) and other restoration efforts. Our goal is to provide managers with locally derived, historically realistic, and climatically sustainable targets for desired future stand and landscape conditions for the Colorado Front Range and South Dakota Black Hills.
