“…Historical fire regimes in the region can be broadly characterized as ranging from relatively infrequent, stand-replacing fire in high-elevation forests and some sagebrush communities, to relatively frequent low-to mixed-severity fire in lower elevation forests . However, variability in climate and periodic widespread mortality from forest pathogens also influenced forest conditions and fire regimes over time (Pierce et al 2004, Brunelle et al 2008, Baker 2009, Whitlock et al 2011.…”

Introduction: Climate change is expected to impose significant tension on the geographic distribution of tree species. Yet, tree species range shifts may be delayed by their long life spans, capacity to withstand long periods of physiological stress, and dispersal limitations. Wildfire could theoretically break this biological inertia by killing forest canopies and facilitating species redistribution under changing climate. We investigated the capacity of wildfire to modulate climate-induced tree redistribution across a montane landscape in the central Rocky Mountains under three climate scenarios (contemporary and two warmer future climates) and three wildfire scenarios (representing historical, suppressed, and future fire regimes). Methods: Distributions of four common tree species were projected over 90 years by pairing a climate niche model with a forest landscape simulation model that simulates species dispersal, establishment, and mortality under alternative disturbance regimes and climate scenarios. Results: Three species (Douglas-fir, lodgepole pine, subalpine fir) declined in abundance over time, due to climate-driven contraction in area suitable for establishment, while one species (ponderosa pine) was unable to exploit climate-driven expansion of area suitable for establishment. Increased fire frequency accelerated declines in area occupied by Douglas-fir, lodgepole pine, and subalpine fir, and it maintained local abundance but not range expansion of ponderosa pine.

“…Although Mountain Pine Beetle is a native species that has co-existed with Whitebark Pine for more than 8500 years (Brunelle et al 2008) and occurs throughout most of the range of Whitebark Pine in Canada, epidemic population levels recently have spread to much of the range in Alberta and British Columbia (CFS 2008). Mountain Pine Beetles kill trees by tunnelling beneath the bark and laying eggs.…”

“…The biomass transfer function we used in our analysis (Seppä et al 2009) provides a method to detect past bark beetle outbreaks by first screening for the probability of beetle disturbances based on host abundance. The method can also help in the interpretation of other proxy indicators of past outbreaks, such as shifts in host/non-host ratio, non-pollen palynomorphs of beetle obligates (e.g., blue stain fungi), and preserved beetle remains found in sediments (Brunelle et al 2008). For example, a number of paleoecological studies of bark beetles have focused on detecting insect disturbances in a similar fashion as wildfire events, by identifying a residual product of the disturbance event in the sedimentary record such as charcoal (e.g.…”

Background: In Western North America, increasing wildfire and outbreaks of native bark beetles have been mediated by warming climate conditions. Bioclimatic models forecast the loss of key high elevation species throughout the region. This study uses retrospective vegetation and fire history data to reconstruct the drivers of past disturbance and environmental change. Understanding the relationship among climate, antecedent disturbances, and the legacy effects of settlement-era logging can help identify the patterns and processes that create landscapes susceptible to bark beetle epidemics. Methods: Our analysis uses data from lake sediment cores, stand inventories, and historical records. Sediment cores were dated with radiometric techniques (
