Climate change represents a substantial challenge for land managers and policy makers. Increasing variability in weather and changing disturbance regimes are important consequences of climate change, and this increased variability will have a large impact on ecosystem structure and function. Consequently, land management practices that influence how and to what degree variability in environmental drivers is propagated to ecosystem processes represent an opportunity to decrease variability in the delivery of ecosystem services. For example, forest thinning that decreases leaf area may moderate the negative effect of drought on tree productivity or mortality. Large herbivore grazing may attenuate effects of climatic variability by decreasing resource demand by plants. Similarly, greater variety in life history strategies resulting from increased plant functional diversity may strengthen the ability of an ecosystem to sustain function during unusual conditions. This session will include speakers from grassland, forested and aquatic systems, as well as additional ecosystem types that may be represented by contributed talks. Environmental variability can be a consequence of fluctuations in weather conditions and/or disturbances. Speakers will examine the consequences of a wide array of management practices on the variability in any ecosystem service for which temporal records are available. Comparing and contrasting results about the effectiveness of management practices across biomes may lead to further synthesis products.
