Tools for Landscape Assessment

Many managers are hampered by the scope of the invasive species problem compared to their available resources. Habitat suitability models of invaders can help fill this resource gap, helping with activities such as watch list compilation and targeted surveillance and eradication efforts.

Sagebrush ecosystems, one of the most imperiled in North America, face continued and widespread degradation due to multiple factors, including climate change, invasive species, and increased human development. Effective sagebrush management must consider how to best conserve and restore habitats to stem the decline of species that rely on them, especially given limited conservation resources. To...

USGS is working closely with partners in the Bureau of Land Management (BLM), U.S. Fish and Wildlife Service (USFWS), and the Intermountain West Joint Venture (IMJV) to collect and summarize spatial datasets that describe measurable aspects of invasive annual grasses (e.g., biomass or presence) across the western United Stated and beyond. The products developed through this project provide...

The Bureau of Land Management (BLM) manages for conditions that sustain land health on over 1 million acres of public rangelands. The BLM has traditionally assessed rangelands using small-scale data, but agency guidance suggests assessment of land health standards at watershed scales. We are exploring methods to integrate remotely sensed data into BLM land health processes.

The National Environmental Policy Act (NEPA) requires federal agencies to assess potential impacts of proposed actions as part of their decision-making processes. Assessing potential cumulative effects is a challenging component of NEPA analyses. We are working with the Bureau of Land Management to develop a process that staff can use to strengthen cumulative effects analyses.

Effective environmental management requires integrating scientific information into complex decision making processes.

The USGS is developing science and decision support tools to inform policy and management decisions about various aspects of the energy development life cycle.

Recent advances in molecular biology allow us to develop and apply the tools and concepts of molecular genetics to the conservation of biological resources. Working with our partners, we design and implement studies that provide genetic and genomic information for a broad range of applications, as detailed below.

The Information Science Branch develops and applies approaches that integrate natural science, computer technology, and information management to address key natural resource issues. Branch staff work with USGS scientists and data managers to convert field observations into GIS-oriented data and metadata products. The Branch also supports ecological and landscape modeling, including the...

National observation and monitoring networks, regardless of their target observation type, share many common needs. Not the least of these needs is the data assembly framework employed by the network - the flow of many types of collected data into a common processing, analysis, and visualization engine. The Information Science Branch uses experiences from similar software and infrastructure...

True data integration across many databases and projects requires new thinking about the design of data collection and distribution applications. Working with multiple USGS partners, the Information Science Branch researched and designed a new approach to software development and deployment that maintains function-based containers connected by web services. This component approach provides...

A central focus of this program is to conduct multi-scale assessments in order to develop related geospatial decision-support tools and methods. The program includes synthesizing broad-scale datasets and developing innovative approaches to assess the vulnerability and resilience of wildlife habitats and ecosystems, relative to land management decisions and ecosystem stressors on Department of the...
