Accelerating contributions of restoration ecology for enhancing natural climate solutions

Such efforts, however, are futile unless we concurrently address the climate crisis. Many restoration actions implicitly or explicitly provide climate mitigation outcomes, and these need to be emphasized and prioritized. Local actions that collectively have global impacts need greater participation of academics, managers, policymakers, and stakeholders. Such actions will reduce the current knowing-versus-doing gap, speed up essential activities, and increase the spatial extent of restoration efforts that benefit climate solutions and provide community resilience to extreme climate events. All landscapes, regardless of the extent of human impacts, are potentially eligible for these actions. Priorities of management that are neutral or negative with respect to climate mitigation need to be reevaluated given the need and availability of similar actions that facilitate climate mitigation. If traditional management programs such as urban construction, tillage, landscaping, roads, trails, and weed control are subsumed within an enhanced climate solutions framework, restoration emerges as the common management theme. Of particular importance, programs that both repair and prepare for current and anticipated catastrophic climatic events deserve priority status. A relatively new paradigm created by land managers, the “Restore-Accept-Direct” model, provides a framework where conservation, human well-being, and enhanced climate solution outcomes can be simultaneously achieved.

Long-term experimental manipulation of winter snow regime and summer temperature in arctic and alpine tundra

This paper describes the experimental design and short-term eects. Open-top ®berglass warming chambers are placed along the experimental snow gradients and in controls areas outside the fences; each warming plot is paired with an unwarmed plot. The purpose of the experiment is to examine short-and long-term changes to the integrated physical-biological systems under simultaneous changes of winter snow regime and summer temperature, as part of the Long-Term Ecological Research network and the International Tundra Experiment. The sites were at Niwot Ridge, Colorado, a temperate high altitude site in the Colorado Rockies, and Toolik Lake, Alaska, a high-latitude site. Initial results indicate that although experimental designs are essentially identical at the arctic and alpine sites, experimental eects are dierent. The drift at Niwot Ridge lasts much longer than do the Toolik Lake drifts, so that the Niwot Ridge fence aects both summer and winter conditions, whereas the Toolik Lake fence aects primarily winter conditions. The temperature experiment also diers in eect between the sites. Although the average temperature increase at the two sites is similar (daily increase 1 . 5 8C at Toolik and 1 . 9 8C at Niwot Ridge), at Toolik Lake there is only minor diurnal variation, whereas at Niwot Ridge the daytime increases are extreme on sunny days (as much as 7±10 8C), and minimum nighttime temperatures in the chambers are often slightly cooler than ambient (by about 1 8C). The experimental drifts resulted in wintertime increases in temperature and CO 2¯u x. Temperatures under the deep drifts were much more consistent and warmer than in control areas, and at Niwot Ridge remained very close to 0 8C all winter. These increased temperatures were likely responsible for observed increases in system carbon loss. Initial changes to the aboveground biotic system included an increase in growth in response to both snow and warming, despite a reduced growing season. This is expected to be a transient response that will eventually be replaced by reduced growth. At least one species, Kobresia myosuroides, had almost completely died at Niwot Ridge three years after fence construction, whereas other species were increasing. We expect in both the short-and long-term to see the strongest eects of snow at the Niwot Ridge site, and stronger eects of temperature at Toolik Lake.
