Earth is experiencing widespread ecological transformation in terrestrial, freshwater, and marine ecosystems that is attributable to directional environmental changes, especially intensifying climate change. To better steward ecosystems facing unprecedented and lasting change, a new management paradigm is forming, supported by a decision-oriented framework that presents three distinct management choices: resist, accept, or direct the ecological trajectory. To make these choices strategically, managers seek to understand the nature of the transformation that could occur if change is accepted while identifying opportunities to intervene to resist or direct change. In this article, we seek to inspire a research agenda...

Climate change is contributing to an increase in wildfire activity in the western United States, including the Blue Mountains and Eastern Cascades Slopes and Foothills of the Inland Northwest. Some forest ecosystems are changing from forest to non-forest because of severe fires, a hot and dry climate, and/or the absence of a viable seed source. On sites impacted by wildfire, managers are tasked with maintaining timber value, wildlife, recreation, and cultural resources important to society. However, managers contend with multiple constraints in forest restoration. To address these constraints, a network of scientists and managers of the Blue Mountains and Eastern Cascades will co-develop a decision support platform...

Increasing fire severity and warmer, drier postfire conditions are making forests in the western United States (West) vulnerable to ecological transformation. Yet, the relative importance of and interactions between these drivers of forest change remain unresolved, particularly over upcoming decades. Here, we assess how the interactive impacts of changing climate and wildfire activity influenced conifer regeneration after 334 wildfires, using a dataset of postfire conifer regeneration from 10,230 field plots. Our findings highlight declining regeneration capacity across the West over the past four decades for the eight dominant conifer species studied. Postfire regeneration is sensitive to high-severity fire, which...

Increasing wildfire activity in the western US poses profound risks for human communities and ecological systems. Recent fire years are characterized not only by expanding area burned but also explosive fire growth. In 2020, several fires grew by >100,000 acres within a 24-hour period. Extreme single-day fire spread events such as these are poorly understood but disproportionately responsible for wildfire impacts: just the top 1% of fire spread events account for 20% of annual area burned. Extreme events are linked to warmer and drier conditions, and we project that their frequency could double under future climate. Extreme fire spread events defy suppression and overcome traditional fuels reductions treatments,...

Fires are becoming more extensive and severe in the West, and post-fire recovery is a challenge for communities as they adapt to a changing climate. Post-fire management can involve watershedrehabilitation, recovering valuable trees, and replanting to prevent forest loss and damage to watersheds. Land management agencies that make decisions may prioritize goals that differ from those of local populations--especially Native American Tribes, who may focus primarily on recovering non-timber values, such wetlands or species that provide food, fiber, or medicine, on their reservations and on their ancestral homelands. The goal of this research is to inform post-fire management and policy, so it is more responsive to...
