Summary of "Examining the vulnerability of localized reforestation strategies to climate change at a macroscale."

Climate change is altering the nature and condition of vast areas in the boreal forest of Canada. There are great uncertainties concerning impacts on the forest, along with how policy and economic responses will translate effectively between local and macroscales. In particular, planting tree seedlings with improved characteristics following harvesting is one localized response strategy considered essential by policymakers. However, planting costs limit the macroscale adoption of this strategy which may result in trade-offs between profitability and reducing vulnerability. In this study, we developed a decision support tool (called Q3) that links stand-level decision making to the macroscale and applied this model to investigate the financial attractiveness of planting improved stocks under one climate change threat, drought-induced seedling mortality. Using several scenarios describing planting effort, improved yields and risk to drought-induced seedling mortality, we showed that adopting improved planting stock strategies across a macroscale (i.e., the western Boreal forest of Canada) can be financially attractive when considering stand-establishment constraints and drought risk. In particular, a proactive approach can be less costly than a reactive approach to drought-induced seedling mortality. To maximize profits, the forestry industry would need to prioritize younger stands closer to processing mills that had a smaller percentage of conifer growing stocks prior to harvest. This research improves the linkages between macroscale policies and forest management activities critical for recommending future development paths that the forestry industry could follow to decrease climate change vulnerabilities.

Medical and Biotech [MESH] Definitions

Any significant change in measures of climate (such as temperature, precipitation, or wind) lasting for an extended period (decades or longer). It may result from natural factors such as changes in the sun's intensity, natural processes within the climate system such as changes in ocean circulation, or human activities.

A type of climate characterized by insufficient moisture to support appreciable plant life. It is a climate of extreme aridity, usually of extreme heat, and of negligible rainfall. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

An animal or plant species in danger of extinction. Causes can include human activity, changing climate, or change in predator/prey ratios.

A climate characterized by COLD TEMPERATURE for a majority of the time during the year.

A climate which is typical of equatorial and tropical regions, i.e., one with continually high temperatures with considerable precipitation, at least during part of the year. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
