The Effect of Large Wildfires on Local Labor Markets
Year: 2012
Although fire managers, policymakers, and communities are benefiting from better understanding of suppression costs, property losses, and community impacts of large fires,4 no generalizable empirical research has quantified the specific effect of large wildfires on local employment and wages. As federal spending on wildfire suppression in the United States continues to grow,5 an understanding of the effects of wildfires on local economies will help natural resource managers, policymakers, and communities better anticipate and make management and policy decisions that support local economies.…

Forest Service Spending on Large Wildfires in the West
Year: 2012
The purpose of this report is to shed light on fire suppression spending as a starting point for understanding the economic impacts of large fires. In this paper, we examined Forest Service suppression spending during and after large wildfire events to explore: (1) what the Forest Service spends money on during and after a wildfire; (2) the kinds of entities and personnel that perform that work; and (3) where funds went.

Community-Based Natural Resource Management in Oregon: A Profile of Organizational Capacity
Year: 2012
Community-based organizations (CBOs) in Oregon are fostering natural resource management and economic development, particularly in public lands communities where the capacity of federal agencies, businesses, and others has dwindled. They have also become integral in reducing social conflict over land management and seeking community economic wellbeing. CBOs include non-governmental organizations and collaborative groups. These groups have broad missions that are grounded in local needs and integrate a number of priorities, but tend to have smaller staff and budgets than other groups such as…

Long-term perspective on wildfires in the western USA
Year: 2012
Understanding the causes and consequences of wildfires in forests of the western United States requires integrated information about fire, climate changes, and human activity on multiple temporal scales. We use sedimentary charcoal accumulation rates to construct long-term variations in fire during the past 3,000 y in the American West and compare this record to independent firehistory data from historical records and fire scars. There has been a slight decline in burning over the past 3,000 y, with the lowest levels attained during the 20th century and during the Little Ice Age (LIA, ca.…

Vegetation's importance in regulating surface elevation in a coastal salt marsh facing elevated rates of sea level rise
Year: 2012
Rising sea levels threaten the sustainability of coastal wetlands around the globe, thus understanding how increased inundation alters the elevation change mechanisms in these systems is increasingly important. Typically, the ability of coastal marshes to maintain their position in the intertidal zone depends on the accumulation of both organic and inorganic materials, so one, if not both, of these processes must increase to keep pace with rising seas, assuming all else constant. To determine the importance of vegetation in these processes, we measured elevation change and surface accretion…

Drought-Driven Disturbance History Characterizes a Southern Rocky Mountain Subalpine Forest
Year: 2012
The view that subalpine forest vegetation dynamics in western North America are "driven" by a particular disturbance type (i.e. fire) has shaped our understanding of their disturbance regimes. In the wake of a recent (1990s) landscape-extent spruce beetle (Dendroctonus rufipennis Kirby) outbreak in the southern Rocky Mountains, we re-examined the temporal continuity in disturbance types and interactions and the possible role of drought on their occurrence by reconstructing antecedent disturbances for 11 sites across the Markagunt Plateau, southern Utah, USA. Multiple consistent lines of…

The leaf-area shrinkage effect can bias paleoclimate and ecology research
Year: 2012
Premise of the Study: Leaf area is a key trait that links plant form, function, and environment. Measures of leaf area can be biased because leaf area is often estimated from dried or fossilized specimens that have shrunk by an unknown amount. We tested the common assumption that this shrinkage is negligible. Methods: We measured shrinkage by comparing dry and fresh leaf area in 3401 leaves of 380 temperate and tropical species and used phylogenetic and trait-based approaches to determine predictors of this shrinkage. We also tested the effects of rehydration and simulated fossilization on…
