Structured science syntheses to inform decision making on Federal public lands
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...

Annotated bibliography of scientific research on Taeniatherum caput-medusae published from January 2010 to January 2022
Integrating recent scientific knowledge into management decisions supports effective natural resource management and can lead to better resource outcomes. However, finding and accessing scientific knowledge can be time consuming and costly. To assist in this process, the U.S. Geological Survey is creating a series of annotated bibliographies on topics of management concern for western...

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
QuestionsEcological communities are controlled by multiple, interacting abiotic and biotic factors that influence the distribution, abundance, and diversity of species. These processes jointly determine resource availability, resource competition, and ultimately species richness. For many terrestrial ecosystems in dryland climates, soil water availability is the most frequent limiting...

Morphology and genesis of giant seafloor depressions on the southeasterncontinental shelf of the Korean Peninsula
We identify and describe five giant seafloor depressions from the southeastern continental shelf of the Korean Peninsula using multibeam bathymetry, sub-bottom profiler, and multi-channel seismic reflection data, supplemented by piston cores. Multibeam bathymetry data from the shelf show four crescent-shaped depressions (SD1 to SD4) and one near-circular depression (SD5) within a group...

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.
