Resilience and resistance concepts have broad application to ecology society. is an emergent property that reflects the amount of disruption a system can withstand before its structure or organization uncharacteristically shift. Resistance component resilience. Before advent intensive forest management fire suppression, western North American forests exhibited naturally occurring resilience wildfires other disturbances. Using evidence from ten ecoregions, spanning Canada Mexico, we review...
Implementation of wildfire- and climate-adaptation strategies in seasonally dry forests western North America is impeded by numerous constraints uncertainties. After more than a century resource land use change, some question the need for proactive management, particularly given novel social, ecological, climatic conditions. To address this question, we first provide framework assessing changes landscape conditions fire regimes. Using framework, then evaluate evidence change contemporary...
More than a century of forest and fire management Inland Pacific landscapes has transformed their successional disturbance dynamics. Regional connectivity many terrestrial aquatic habitats is fragmented, flows some ecological physical processes have been altered in space time, the frequency, size intensity disturbances that configure these altered. Current efforts to address impacts yield small footprint comparison wildfires insect outbreaks. Moreover, current projects emphasize thinning...
LiDAR individual tree detection (ITD) is a promising tool for measuring forests at scale that meaningful ecologically and useful forest managers. However, most ITD research evaluates methods over small homogeneous areas, while many managers work large, complex landscapes. We investigated how results varied across diverse structural conditions in California's Sierra Nevada mixed-conifer what this taught us about when to apply ITD. Our suggest it advantageous use improves analysis...
Abstract For over 20 years, forest fuel reduction has been the dominant management action in western US forests. These same actions have also associated with restoration of highly altered frequent-fire Perhaps vital element compatibility these treatments is that both need to incorporate salient characteristics frequent fire produced—variability vegetation structure and composition across landscapes inability support large patches high-severity fire. can be achieved mechanical treatments. The...
Abstract This paper presents a prototype Carbon Monitoring System (CMS) developed to produce regionally unbiased annual estimates of aboveground biomass (AGB). Our CMS employed bottom-up, two-step modeling strategy beginning with spatially and temporally biased sample: project datasets collected contributed by US Forest Service (USFS) other forestry stakeholders in 29 different areas the northwestern USA. Plot-level AGB served as response variable for predicting primarily from lidar metrics...
Abstract Following a wildfire, regeneration to forest can take decades centuries and is no longer assured in many western U.S. environments given escalating wildfire severity warming trends. After large fire years, managers prioritize where allocate scarce planting resources, often with limited information on the factors that drive successful establishment. Where occurring, long‐term effects of postfire salvage operations increase uncertainty Here, we collected field data patterns within 13‐...
The 1994 Northwest Forest Plan signified a watershed moment for natural resource management on federal lands in the Pacific Northwest. It established clear priorities ecologically motivated of terrestrial and aquatic ecosystems biodiversity conservation nearly 10 million hectares public Oregon, Washington, northern California. Conservation reserves were primary means safeguarding remaining old forest riparian habitats, populations spotted owl, marbled murrelet, salmon that depend them. As...
We analyzed spatial patterns of overstory trees in late-successional Abies amabilis (Dougl. ex Loud.) Dougl. J. Forbes forests and Pseudotsuga menziesii (Mirb.) Franco to establish reference for restoration thinning treatments, determine whether treatments with minimum intertree spacing rules result characteristic forests. On average, 32.7% plots 26.3% occurred as members multitree clusters (groups which are spaced within a specified distance each other) at 3.0 4.0 m, respectively. Multitree...
