Species have become extinct throughout geological history. Biological evolution, driven by natural climate change, catastrophic geologic events, and competition from better-adapted species, has involved extinction of billions of species since the advent of life on Earth about three billion years ago.

Metrics details. Wildfires in the Pacific Northwest Washington, Oregon, Idaho, and western Montana, USA have been immense in recent years, capturing the attention of resource managers, fire scientists, and the general public. This paper synthesizes understanding of the potential effects of changing climate and fire regimes on Pacific Northwest forests, including effects on disturbance and stress interactions, forest structure and composition, and post-fire ecological processes.

Climate change adaptation

Climate change adaptation is the process of adjusting to current or expected climate change and its effects. Adaptation actions can be either incremental actions where the central aim is to maintain the essence and integrity of a system or transformational actions that change the fundamental attributes of a system in response to climate change and its impacts. The need for adaptation varies from place to place, depending on the sensitivity and vulnerability to environmental impacts. The adaptation challenge grows with the magnitude and the rate of climate change. Even the most effective climate change mitigation [13] through reduction of greenhouse gas GHG emissions or enhanced removal of these gases from the atmosphere through carbon sinks [14] would not prevent further climate change impacts, making the need for adaptation unavoidable.

Adaptation of forest management to climate change requires an understanding of the effects of climate on forests, industries and communities; prediction of how these effects might change over time; and incorporation of this knowledge into management decisions. This requires multiple forms of knowledge and new approaches to forest management decisions. Partnerships that integrate researchers from multiple disciplines with forest managers and local actors can build a shared understanding of future challenges and facilitate improved decision making in the face of climate change. Climate change presents significant potential risks to forests and challenges for forest managers. Adaptation to climate change involves monitoring and anticipating change and undertaking actions to avoid the negative consequences and to take advantage of potential benefits of those changes.

Attempts to impose stability on inherently dynamic systems are widely recognized by the scientific and conservation communities as futile, given the rapid pace of current changes in climate and land use and the ubiquity of disturbance as an organizing force in ecosystem dynamics Holling and Meffe The recognition that ecosystems are intrinsically unstable, however, often conflicts with prevailing land management strategies designed to preserve steady-state conditions and ensure reliable delivery of ecosystem goods and services to meet human needs North et al. Ecosystem science points to a need for management and conservation strategies that can better accommodate change as well as novel conditions Higgs et al. However, in many areas, a lack of information about past variability or future trajectories of change confounds long-range resource management planning North and Keeton , van Wilgen and Biggs Proactive strategies would include consideration of key ecological processes that have operated in the past and are likely to be important in the future, including critical thresholds of climate change, levels of natural and human-induced disturbance, the extent of land-cover change, and sensitivity of species to environmental change Grumbine , , Biggs et al.

Climate change is posing a considerable challenge to foresters. The intensity of required adaptive measures and the relevance of old-growth forests as benchmark for managed forests are debated. Forest managers need to make decisions on stand treatment that are based on climatological and biological parameters with high uncertainties.
