Current Research
My research focuses on studies in stand dynamics that include maximum density-site relationships, growth and yield implications of mixed-species stands, and effects of stand senescence on stand structure and regeneration; partitioning forest mortality by background (e.g., density dependence, endemic insect and disease) vs. excess (e.g., drought) causes; new, biologically consistent models of tree and stand growth
Past Research

My background and past research has primarily been in the areas of forest management and quantitative silviculture.

Research Interest
I work to maximize the value of the Forest Inventory Analysis (FIA) program by expanding the potential range of analyses and developing useful and relevant tools from the FIA data. This research will produce tools and models that will allow more accurate assessment and modeling of stand dynamics. These will enable managers to project more realistic scenarios when considering vegetation management or the effects of anticipated disturbances.
Why This Research Is Important

The FIA program covers all forest types on all land owverships of the U.S. Because of this comprehensive coverage, it is possible to make generalizations about the status and trends of U.S. forest land that are not possible using smaller, localized datasets. Therefore, forest issues and characteristics that are described at smaller scales can be set in the context of all U.S. forests. While FIA data are primarily designed for long-term, broad-scale analysis and reporting, they can be used for a wide variety of analysis and reporting applications. FIA data can be brought to bear on basic research questions that cannot be definitively addressed using shorter temporal or smaller geographic time scales. FIA data permit testing of study results that have been done at limited scales, resulting in better understanding of the range of inference that is appropriate for those studied. Similarly, a variety of hypotheses may also be tested, without the need to initiate stand-alone studies.

Research Highlights

New report offers comprehensive inventory of Colorado’s forests

Year: 2017
The current inventory of Colorado’s forests is the first to use the complete set of Forest Inventory and Analysis (FIA) plots across all ownerships and forest types. The inventory was completed at a time when Colorado forests were undergoing substantial change, primarily in the form of insect infest...

Dendroecological Studies in the Interior West States

Year: 2015
Scientists produce tree ring data in digital format and make progress on data development for growth studies to analyze regional patterns of climate, disturbance, and other ecosystem-scale processes.

Drought Leaves a Lasting Impression on Trees

Year: 2015
Some effects of drought, such as tree mortality, are obvious, but relatively little is known about non-lethal impacts. This study showed that the impacts of drought linger beyond the end of dry periods.

Spatial Variability of Tree Growth in the Interior West

Year: 2016
A fundamental goal of biogeography is to understand the factors that drive spatial and temporal variability in forest growth across large areas. The Interior West Forest Inventory and Analysis program collected tree-ring data from thousands of plots that can be used to investigate controls on growth...

Building the Forest Inventory and Analysis Tree-ring Dataset

Year: 2016
Tree-ring data collected as part of the Forest Inventory and Analysis program in the Interior West is being assembled into a massive dataset with many tens- of thousands of trees. Given the underlying sampling approach to the Forest Inventory and Analysis grid, the tree-ring data collected can be us...

Living on the Edge: Trailing Edge Forests Are at Risk

Year: 2019
Forests are an incredibly important resource across the globe, yet they are threatened by climate change through stressors such as drought, insect outbreaks, and wildfire. Trailing edge forests, those areas expected to experience range contractions under a changing climate, are of concern because of...
