Article
Climate-driven increases in disturbance frequency and extent augment the potential for compounded disturbances. Drawing on well-studied forests that experienced successive disturbances, we asked: (1) how does post-fire cover of litter, herbaceous cover and bare ground vary between stands affected by combinations of blow-down, insect outbreak, and f...

The ability to estimate and model future vegetation dynamics is a central focus of contemporary ecology and is essential for understanding future ecological trajectories. It is therefore critical to understand when the influence of initial post-disturbance regeneration versus stochastic processes dominates long-term post-disturbance ecological proc...
Article
This paper demonstrates methods that may be combined to characterize otherwise undetectable spatial heterogeneity in stated preference willingness to pay (WTP) estimates that may occur at multiple geospatial scales. These include methods applicable to large-scale analysis with diffuse policy impacts and uncertainty regarding the appropriate scales...
Article
A subcontinental-scale outbreak of mountain pine beetle (MPB; Dendroctonus ponderosae) has affected millions of hectares of forest in the western USA and Canada over the past 15 years. Little research has examined the long-term and broad-scale history of MPB outbreaks, which is necessary to provide a baseline for comparing current and future outbre...
Article
This study examines influences of climate variability on spruce beetle (Dendroctonus rufipennis) outbreak across northwestern Colorado during the period 1650 2011 CE. Periods of broad-scale outbreak reconstructed using documentary records and tree rings were dated to 1843-1860, 1882-1889, 1931-1957, and 2004-2010. Periods of outbreak were compared...

Mountain pine beetle (MPB) outbreaks in North America are widespread and have potentially persistent impacts on forest albedo and associated radiative forcing. This study utilized multiple data sets, both current and historical, within lodgepole pine stands in the south-central Rocky Mountains to quantify the full radiative forcing impact of outbre...

This study utilized multiple datasets, both current and historical, within lodgepole pine stands in the south-central Rocky Mountains in order to quantify both the full radiative forcing imp...
Article
Both fire and insect outbreaks are critical components of many forest ecosystems and understanding the two-way interactions between these disturbance types is an important goal for researchers, resource managers, and policy makers. Much recent research has focused on understanding the effects of outbreaks on subsequent fires, but the effects of fir...
Article
As the extent, magnitude and/or frequency of various forest disturbances are increasing due to climate change, it is becoming increasingly likely that forests may be affected by more than one type of disturbance in short succession. We studied how compounded disturbances and pre-fire composition influence post-fire tree regeneration. Specifically,...
Article
Aim As climate change is increasing the frequency, severity and extent of wildfire and bark beetle outbreaks, it is important to understand how these disturbances interact to affect ecological patterns and processes, including susceptibility to subsequent disturbances. Stand-replacing fires and outbreaks of mountain pine beetle (MPB), Dendroctonus...
Conference Paper
Background/Question/Methods Large infrequent disturbances are essential in dictating ecosystem structure and composition, which in turn may affect a forest’s susceptibility to subsequent disturbances. The major coarse-scale disturbances affecting spruce-fir forests in Colorado and Wyoming are wildfire and spruce beetle (SB; Dendroctonus rufipenni...
Article
Outbreaks of bark beetles and drought both lead to concerns about increased fire risk, but the relative importance of these two factors is the subject of much debate. We examined how mountain pine beetle (MPB) outbreaks and drought have contributed to the fire regime of lodgepole pine forests in northwestern Colorado and adjacent areas of southern...
