In this paper, the authors describe an approach to facilitate development and implementation of climate change adaptation options in forest management which they applied to a case study area in southwestern Oregon, USA. Their approach relied on participation of local specialists across multiple organizations to establish a science–manager partnership, development of climate change education in multiple formats, hands-on development of adaptation options, and application of tools to incorporate climate change in planned projects.

In this study, researchers used data from the US Forest Service’s National Resource Ordering and Status System to investigate how private sector resources were dispatched to fires. In particular, they examined the dispatch of private engines in the Northwest Geographic Area (GA), which encompasses Oregon and Washington, from 2008 to 2015. The researchers also investigated how private sector engine capacity compared to demand by focusing on engine dispatch during the 2015 fire season, which was widely considered the most severe in the Northwest’s modern history.

Continued conflict around natural resource management and dwindled public confidence in land management agencies has necessitated the development of a new collaborative social contract for land management in the West. However, even within the sphere of collaboration, restoring the key characteristics of landscape resilience to landscapes has been a challenge. Science has a golden opportunity to help inform a sound socio-ecological approach to restorative management, which can be understood by all land ownership and partners. To help guide these landscape planning efforts, researchers have created a framework of seven core principles and their implications for management of fire-prone interior forest landscapes.

In this paper, researchers examine the problem of growing wildfire risk through a coupled natural and human systems (CNHS) perspective. They characterized the primary social and ecological dimensions of what they termed a socioecological pathology of wildfire risk in temperate forests, or “a set of complex and problematic interactions among social and ecological systems across multiple spatial and temporal scales.” By paying particular attention to the wildfire risk governance system, which is influenced by both ecological conditions and diverse parties with competing goals, policies, and practices, the authors investigate strategies for reducing wildfire risk.

This study investigated the long-term response of understory vegetation to two post-fire logging treatments (commercial salvage logging with and without additional fuel reduction logging) in northeastern Oregon. Researchers assessed if there were lasting effects on understory plant cover, species diversity, plant community composition, and exotic species cover in experimental treatment units 15 years post-treatment. The study area is located within the area burned by the 1996 Summit Fire, which burned mostly at high severity although it occurred in dry coniferous forests that historically burned at frequent intervals (14-16 years) and at low severity.

In this study, researchers developed models of freshwater habitat for spring Chinook Salmon in pre- and post-fire scenarios in the Wenatchee River sub-basin of central Washington, where a large number of wildfires have occurred in the past 30 years. They predicted changes in in-stream wood, sediment, and water temperature as a result of wildfires and modeled their influence on habitat quality for three life stages (egg/fry, juvenile, and adult) of spring Chinook Salmon. They also compared their model results with the current and historic distribution of spring Chinook Salmon to better understand if decreasing populations are distributed in ways that correlate with fire impacts on habitats.

Previous research has focused on quantifying fuel loadings and using operational fire behavior models to understand changes in fire severity following MPB outbreaks. In this study however, researchers used direct field measurements taken from the 2012 Pole Creek Fire that burned in lodgepole pine forests in central Oregon’s Eastern Cascade Mountains, which had experienced a MPB epidemic 8-15 years prior to the fire. They examined the combined effects of MPB and fire disturbances on stand structure, and investigated the influence of previous MPB severity and fire weather on subsequent fire severity and cumulative disturbance severity.

In this study, researchers analyzed the influence of pre-incident familiarity, stakeholder affiliation, and primary wildfire response/functional role on communication frequency and efficacy during three western U.S. wildfires ignited on U.S. Forest Service land. All fires occurred in wildland/urban interface areas, and involved a range of parties including Type 1 Incident Management Team response teams, local forest leaders, and responding agencies.

In this study, researchers investigated the extent of forest restoration needed to move present day forests towards a NRV across fire-adapted landscapes in eastern Washington, eastern Oregon, and southwestern Oregon. They assessed forest vegetation restoration needs for over 28 million acres of forest based on the distribution of different forest types (e.g., Dry Mixed Conifer vs. Moist Mixed Conifer) and the current relative abundance of structural classes (see below) compared to NRV reference conditions. Using this approach, researchers determined which structural classes were overrepresented and underrepresented in each landscape unit. They then evaluated which of several different treatment or restoration categories (‘Disturbance Only’, ‘Disturbance then Succession’, and ‘Succession Only’) could transition acres to structural classesthat would restore a distribution of classes to within the NRV reference conditions.

In this study, researchers analyzed how previous management effortsand other factors including weather and landform influenced burn severityduring the 2006 Tripod Complex Fires, which at the time represented thelargest wildfire event in over 50 years in the state of Washington. The TripodComplex burned over 170,000 acres of mixed-conifer forests, including 387past harvest and fuel-treatment units. By evaluating differences in burn severityin areas with and without harvest and fuel treatments, as well as between areaswith different landform, vegetation, insect outbreak, and weather duringburning, researchers evaluated the relative influence of these drivers on burnseverity during the fire.
