Rangeland drought: Effects, restoration, and adaptation [Chap. 8]

Publications Posted on: February 10, 2016
Drought can have severe impacts on rangeland ecosystems in North America. For the purposes of this chapter, rangelands include natural grasslands, savannas, shrublands, many deserts, tundras, alpine communities, marshes, meadows, and woodlands. Drought impacts vary depending on the severity, frequency, duration, and aerial extent of the drought(s); how the land is managed; and whether plans are in place and implemented to respond to drought.

Effects of drought on forests and rangelands in the United States: a comprehensive science synthesis

Publications Posted on: February 02, 2016
This assessment provides input to the reauthorized National Integrated Drought Information System (NIDIS) and the National Climate Assessment (NCA), and it establishes the scientific foundation needed to manage for drought resilience and adaptation. Focal areas include drought characterization; drought impacts on forest processes and disturbances such as insect outbreaks and wildfire; and consequences for forest and rangeland values.

Assessing vulnerability of species of conservation concern

Science Spotlights Posted on: April 14, 2015
Climate change is having dramatic impacts on the distribution and population connectivity of wildlife species the western United States. This project is combining vast sampling of species occurrence and genetic characteristics with sophisticated spatial modeling of gene flow, connectivity, and adaptive variation. This research will benefit society by providing detailed and specific predictions of the effects of climate change on wildlife across a vast area of the United States, and it can inform development of optimized adaptation strategies to mitigate the negative effects of climate change on forest ecosystems.

Advanced methods of monitoring for species of conservation concern

Science Spotlights Posted on: April 14, 2015
Scientists with the Rocky Mountain Research Station and their collaborators have made great contributions to the development and application of broad-scale, representative, multi-resource monitoring protocols. They have played a key role in developing and improving sampling methodology, survey design, and analysis of non-invasively collected genetic data.

Simulating the impacts of disturbances on forest carbon cycling in North America: processes, data, models, and challenges

Publications Posted on: February 24, 2012
Forest disturbances greatly alter the carbon cycle at various spatial and temporal scales. It is critical to understand disturbance regimes and their impacts to better quantify regional and global carbon dynamics. This review of the status and major challenges in representing the impacts of disturbances in modeling the carbon dynamics across North America revealed some major advances and challenges.

The Forest Vegetation Simulator: A review of its structure, content, and applications

Publications Posted on: September 04, 2007
The Forest Vegetation Simulator (FVS) is a distance-independent, individual-tree forest growth model widely used in the United States to support management decisionmaking. Stands are the basic projection unit, but the spatial scope can be many thousands of stands. The temporal scope is several hundred years at a resolution of 510 years. Projections start with a summary of current conditions evident in the input inventory data.
