Developing structured science syntheses for use in NEPA analyses and decision making in the Bureau of Land Management
Science information is fundamental to understanding how proposed actions on public lands may impact the environment. However, agencies often have limited time to compile and synthesize existing science. We are working with land management agencies to develop a new type of science product— structured science syntheses—for facilitating the use of science information in public lands decisions.
Developing Science Plans for the Bureau of Land Management’s National Landscape Conservation System
The Bureau of Land Management’s National Landscape Conservation System seeks to conserve, protect, and restore nationally significant landscapes. Science is a critical piece of this effort. The US Geological Survey is working with the Bureau of Land Management to develop Science Plans to help prioritize and support science efforts to better understand and manage resources in these landscapes.
Developing searchable annotated bibliographies for resource managers
Resource management decisions need to be informed by up-to-date, quality science and data. However there is sometimes an overwhelming number of scientific publications for managers to consider in their decisions. This project provides concise summaries of recent, peer-reviewed science and data products about different resources and topics of management concern, integrated into a searchable tool.
Scientific opportunities in the National Landscape Conservation System Scientific opportunities in the National Landscape Conservation System
The National Landscape Conservation System consists of unique and beautiful places across America’s landscapes where identified resources and values are protected and science is highlighted. The mission of the National Landscape Conservation System (NLCS), which is managed by the Bureau of Land Management and is often referred to as the agency’s National Conservation Lands, is to...

Bridging theory and practice to inform seed selection for restoration Bridging theory and practice to inform seed selection for restoration
Introduction Land managers often face the critical decision of what plant materials to select for ecological restoration. Selection depends on factors that span ecological conditions and human interventions in the restoration process, which can strongly influence the recovery of a degraded ecosystem. Objectives To improve the seed selection process, we compared scientific literature and...

Effects of nonmotorized recreation on ungulates in the western United States—A science synthesis to inform National Environmental Policy Act analyses Effects of nonmotorized recreation on ungulates in the western United States—A science synthesis to inform National Environmental Policy Act analyses
The U.S. Geological Survey is working with Federal land management agencies to develop a series of science syntheses to support National Environmental Policy Act (NEPA) analyses. This report synthesizes science information about the potential effects of nonmotorized recreation on ungulates in the western United States. We conducted a structured literature search to find published science...

Dryland fungi are spatially heterogeneous and resistant to global change drivers Dryland fungi are spatially heterogeneous and resistant to global change drivers
Fungi are considered particularly important in regulating the structure and function of dryland ecosystems, yet the response of dryland fungal communities to global change remains notably understudied. Without a clear understanding of how fungi respond to global change drivers, mitigation plans—required for biodiversity and ecosystem service conservation and restoration—are impossible to...

The U.S. Geological Survey, Bureau of Land Management, and U.S. Fish and Wildlife Service partnered to develop a new type of science product: the structured science synthesis. Structured science syntheses are peer-reviewed reports that synthesize science information about a priority resource management issue on public lands. Structured science syntheses are developed explicitly to...

Disturbance amplifies sensitivity of dryland productivity to precipitation variability Disturbance amplifies sensitivity of dryland productivity to precipitation variability
Variability of the terrestrial global carbon sink is largely determined by the response of dryland productivity to annual precipitation. Despite extensive disturbance in drylands, how disturbance alters productivity-precipitation relationships remains poorly understood. Using remote-sensing to pair more than 5600 km of natural gas pipeline corridors with neighboring undisturbed areas in...

Extreme drought impacts have been underestimated in grasslands and shrublands globally Extreme drought impacts have been underestimated in grasslands and shrublands globally
Drought has well-documented societal and economic consequences. Climate change is expected to intensify drought to even more extreme levels, but because such droughts have been historically rare, their impact on ecosystem functioning is not well known. We experimentally imposed the most frequent type of intensified drought—one that is ~1 y in duration—at 100 grassland and shrubland sites...

Soil water availability shapes species richness in mid-latitude shrub steppe plant communities Soil water availability shapes species richness in mid-latitude shrub steppe plant communities
QuestionsEcological communities are controlled by multiple, interacting abiotic and biotic factors that influence the distribution, abundance, and diversity of species.
