Climate Change


Located on the Sierra Ancha Experimental Forest, this project uses a common garden approach to determine which plant species are best suited for supporting pollinator communities and are most appropriate for restoration activities. Findings from the study will be used to 1) improve pollinator habitat, 2) increase seed stocks of native flowering species for use in restoration, 3) inform U.S. seed zone guidelines and 4) help predict plant-pollinator response to climate change. This carries on a long tradition at the Sierra Ancha Experimental Forest of using common gardens in botanical research. As far back as the 1920s and 30s common gardens were used to study evapotranspiration rates of native herbaceous and shrub species as well as evaluate the potential use of certain species for erosion control. Some of these the same gardens are now being restored nearly a century later for use in this study.
This project incorporates historical data collected at the Sierra Ancha Experimental Forest nearly 100 years ago to determine how plant communities have changed over that period of time.
The Sierra Ancha Experimental Forest (SAEF) Vegetation Mapping Project uses unmanned aerial vehicles (UAVs) to create highly detailed vegetation maps using Structure From Motion technology.  These maps are then used to overlay historical vegetation maps made nearly 100 years ago to determine how vegetation has changed over the last century.
With increasing temperatures due to climate change and the inherent interannual variability in precipitation of most grasslands, droughts will likely increase in frequency and intensity across the Great Plains. Precipitation legacies from previous years can impact current year productivity in arid grasslands by shifting tiller and bud bank densities of the dominant grasses. Belowground bud survival during drought and the ability of buds to break dormancy following drought are key to maintaining a resilient grassland in both arid and mesic grasslands.
The research objective is to develop western white pine management strategies focused on regeneration establishment and young forest development by 1) developing canopy opening size thresholds where western white pine can establish and grow, 2) developing alternative tending methods to enable managers to continue to manage western white pine plantations, 3) evaluating plantation resilience to wildfire, and 4) evaluating understory plant diversity under 30-year or older western white pine plantations.  
Through fire management and riparian ecosystem restoration RMRS researchers Terrie Jain, Kate Dwire, and Travis Warziniack are partnering with the University of Idaho and the Idaho City Ranger District to develop, implement, and evaluate different adaptive management strategies to improve the fire resiliency of the Boise National Forest. 
Storage of atmospheric carbon is an important ecosystem service of healthy forests and woodlands because it mitigates the effects of anthropogenic greenhouse gas emissions. International reporting of this service places a premium on the specificity and precision of monitoring data used to estimate carbon storage or emission. An inventory of land cover change is a critical component of most national-level accounting systems, and the Landsat series of satellites is a uniquely positioned to provide this land cover change “activity data.” In Eastern Africa, there are already high-quality Landsat-based cover maps for 2 or 3 points in time. However, these maps do not provide the annual land cover change information needed for higher-tier IPCC reporting, and land cover changes inferred from independent maps at different dates cannot easily be assigned a level of uncertainty.
A historically consistent and broadly applicable monitoring, reporting, and verification system based on lidar sampling and Landsat time-series (tested in the US, and applied to the US NGHGI reporting system).
We will deliver a spatially explicit predictive tool depicting resilience to disturbance and resistance to cheatgrass (Bromus tectorum) invasion across the Great Basin.
The Lassen and Modoc National Forests are revising their Forest Plans, guided by the 2012 Planning Rule. This requires public and tribal input throughout the process and embraces the fact that ecological, social, and economic objectives are interrelated. Because ecological, social, and economic conditions have changed since the original forest plans were written and new science is available, preparing a science synthesis, guided by input from the public, tribes, and forest staffs, is the first step in a multi-step process that eventually leads to revised forest plans.
