1) We have little detailed knowledge about fire regimes of mid- higher elevation forests in the northern Rockies, and I am performing fire scar and tree demographic analysis across multiple climate zones in Western Montana in mid- high-elevation forests. 2) Fire-climate outlooks ( Seasonal - > 1 year) can be used by fire managers for longterm resource planning. I am co-PI of a team evaluating past large-scale climate/fire relationships across western North America 3) I am leading several new analytical approaches to fire history data and tool development for performing them 4) I am continuing work from my previous assignment in Ohio on fire regimes and prescribed burning treatments in oak forests.
My research interests include using tree-ring analysis and other research tools to understand disturbance processes (particularly fire) and landscape pattern, and relationships to climate; using tree-ring analysis to understand how physical injuries from events like fire affects wood and scar formation processes. My professional interests extend to synthesizing existing scientific information for scientists and managers and studying the relationship between disturbance and forest community dynamics, and application of prescribed burn.
This research is particularly useful for land and fire managers at all levels (for example, Districts, Forests, Regions) when they are developing plans. They are required to demonstrate understanding about how forests and other vegetation types developed the way they did, and what management approaches would be useful in making the plan successful. Disturbance, especially fire, is an important process in most forests; the results from my work shows how fire varies at broad spatial and temporal scales in higher-elevation forests. My work is also used by other scientists, to understand fire regimes in these forest types and in applying the methods I develop in analyzing fire history data.
1) The focus of my early work was how fire suppression (and other historical factors), and then prescribed burning (and indirect effects), affected the growth of ponderosa pines in northern Arizona. 2) This was good preparation for my postdoctoral work in Utah, where I investigated the effects of historical sulphur dioxide smelting on Douglas-fir ecophysiology and growth. 3) In my first assignment for Forest Service Research in Ohio, I investigated the history of fire in oak forests (previously considered asbestos forests), and initiated experiments applying prescribed burning to regenerate oak forests; this work influenced how Region 9 now manages oak forests. 4) I moved to western Montana and began my current research (and research administration), but also led a team synthesizing information about the environmental consequences of fuel treatments on ponderosa pine (US westwide).
