Integrating the evidence for a terrestrial carbon sink caused by increasing atmospheric CO2 Integrating the evidence for a terrestrial carbon sink caused by increasing atmospheric CO2
Atmospheric carbon dioxide concentration ([CO2]) is increasing, which increases leaf‐scale photosynthesis and intrinsic water‐use efficiency. These direct responses have the potential to increase plant growth, vegetation biomass, and soil organic matter; transferring carbon from the atmosphere into terrestrial ecosystems (a carbon sink). A substantial global terrestrial carbon sink would...

The Fire and Tree Mortality Database, for empirical modeling of individual tree mortality after fire The Fire and Tree Mortality Database, for empirical modeling of individual tree mortality after fire
Wildland fires have a multitude of ecological effects in forests, woodlands, and savannas across the globe. A major focus of past research has been on tree mortality from fire, as trees provide a vast range of biological services. We assembled a database of individual-tree records from prescribed fires and wildfires in the United States. The Fire and Tree Mortality (FTM) database...

Tree-ring evidence of forest management moderating drought responses: Implications for dry, coniferous forests in the southwestern United States Tree-ring evidence of forest management moderating drought responses: Implications for dry, coniferous forests in the southwestern United States
Drought, coupled with rising temperatures, is an emerging threat to many forest types across the globe. At least to a degree, we expect management actions that reduce competition (e.g., thinning, prescribed fire, or both) to improve growth of residual trees during drought. The influences of management actions and drought on individual tree growth may be measured with high precision using...

Subalpine sentinels: Understanding & managing whitebark pine in California Subalpine sentinels: Understanding & managing whitebark pine in California
A hardy inhabitant of the subalpine zone of western North America, whitebark pine (Pinus albicaulis) is a keystone tree species in California’s subalpine forests, where it regularly defines the upper treeline in the Sierra Nevada, Cascade, Warner, and Klamath Mountains. Walking portions of the John Muir Trail in the southern Sierra Nevada, moving through extensive stands and mats of...

Coming to terms with the new normal: Forest health in the Sierra Nevada Coming to terms with the new normal: Forest health in the Sierra Nevada
The vast conifer forests of California’s Sierra Nevada range inspire awe and create lasting memories. The size and longevity of these trees make them seem both otherworldly and everlasting. Indeed, their grandeur is such that visitors may not appreciate how these forests are connected to the larger landscape, and so there is little understanding that something as common as a drought...

The influence of pre-fire growth patterns on post-fire tree mortality for common conifers in western U.S. parks The influence of pre-fire growth patterns on post-fire tree mortality for common conifers in western U.S. parks
Fire severity in forests is often defined in terms of post-fire tree mortality, yet the influences on tree mortality following fire are not fully understood. For trees that are not killed immediately by severe fire injury, pre-fire growth may partially predict post-fire mortality probabilities for conifers of the western U.S. Here, we consider the influence of multiple growth patterns on...

Fire, climate and changing forests Fire, climate and changing forests
A changing climate implies potential transformations in plant demography, communities, and disturbances such as wildfire and insect outbreaks. How do these dynamics play out in terrestrial ecosystems across scales of space and time? “Vegetation type conversion” (VTC) is a term used to describe abrupt and long-lasting changes in vegetation structure and composition due to various kinds of

Fire and tree death: Understanding and improving modeling of fire-induced tree mortality Fire and tree death: Understanding and improving modeling of fire-induced tree mortality
Each year wildland fires kill and injure trees on millions of forested hectares globally, affecting plant and animal biodiversity, carbon storage, hydrologic processes, and ecosystem services. The underlying mechanisms of fire-caused tree mortality remain poorly understood, however, limiting the ability to accurately predict mortality and develop robust modeling applications, especially...

Pre‐fire drought and competition mediate post‐fire conifer mortality in western U.S. National Parks Pre‐fire drought and competition mediate post‐fire conifer mortality in western U.S. National Parks
Tree mortality is an important outcome of many forest fires. Extensive tree injuries from fire may lead directly to mortality, but environmental and biological stressors may also contribute to tree death. However, there is little evidence showing how the combined effects of two common stressors, drought and competition, influence post‐fire mortality. Geographically broad observations of...

Thinning, tree-growth, and resistance to multi-year drought in a mixed-conifer forest of northern California Thinning, tree-growth, and resistance to multi-year drought in a mixed-conifer forest of northern California
Drought is an important stressor in forest ecosystems that can influence tree vigor and survival. In the U.S., forest managers use two primary management techniques to promote resistance and resilience to drought: prescribed fire and mechanical thinning. Generally applied to reduce fuels and fire hazard, treatments may also reduce competition for resources that may improve tree-growth...

Characterizing interactions between fire and other disturbances and their impacts on tree mortality in western U.S. Forests Characterizing interactions between fire and other disturbances and their impacts on tree mortality in western U.S. Forests
Increasing evidence that pervasive warming trends are altering disturbance regimes and their interactions with fire has generated substantial interest and debate over the implications of these changes. Previous work has primarily focused on conditions that promote non-additive interactions of linked and compounded disturbances, but the spectrum of potential interaction patterns has not...

Higher sensitivity and lower specificity in post-fire mortality model validation of 11 western US tree species Higher sensitivity and lower specificity in post-fire mortality model validation of 11 western US tree species
Managers require accurate models to predict post-fire tree mortality to plan prescribed fire treatments and examine their effectiveness. Here we assess the performance of a common post-fire tree mortality model with an independent dataset of 11 tree species from 13 National Park Service units in the western USA. Overall model discrimination was generally strong, but performance varied...
