Steven E Hanser
Since 2019, Steve Hanser has provided senior leadership at the Fort Collins Science Center, serving as Deputy Center Director and, since April 2025, as Acting Center Director. He guides major scientific initiatives that support management of complex natural‑resource challenges.
Steve Hanser’s career centers on advancing applied science that supports decision‑making across the Department of the Interior, Federal agencies, State wildlife agencies, and partner organizations. His scientific work spans landscape ecology, species and habitat assessments, and the development of integrated data and decision‑support tools. Steve has led interdisciplinary teams that produce high‑impact science used to inform policy and on‑the‑ground management. His work includes synthesizing natural resource information across large landscapes, developing multi‑agency research priorities, and improving access to authoritative data for species and habitat management. He has overseen the development of geospatial analyses, monitoring frameworks, and integrative modeling tools that help agencies evaluate vegetation conditions, assess risk, and allocate resources more effectively.
In his leadership roles, Steve has strengthened inter‑agency coordination, expanded collaborative research networks, and championed efforts to improve communication and data sharing across the natural resource community. His focus on transparent, accessible, and actionable science has helped ensure that research produced by USGS and the Fort Collins Science Center directly supports management needs across ecosystems and jurisdictions.

Land management research in support of streamlined energy development, economic growth, and wildfire management
FORT researchers provide sound science to support the Department of the Interior in its efforts to streamline reliable energy development, enhance cost efficiency in public lands management, and manage fire-prone habitats for public safety. This research is developed in partnership with resource managers from local, State, Federal and Tribal governments, industry, and nongovernmental organizations...
Social and economic analysis research in support of public safety, outdoor recreation, and economic growth
FORT researchers provide sound science to support the Department of the Interior in its efforts to reduce the risks wildfires pose to people and property, expand outdoor recreation and tourism opportunities, and promote economic decision making in public lands management. This research is developed in partnership with resource managers from local, State, Federal and Tribal governments, industry...
Developing science syntheses to facilitate climate-informed land management decisions and NEPA analyses on rangelands in the sagebrush biome
The National Environmental Policy Act (NEPA) requires federal public land managers to assess potential environmental impacts of proposed actions. The USGS, Bureau of Land Management, US Fish and Wildlife Service, Colorado State University, and North Central Climate Adaptation Science Center are working together to develop science syntheses that can facilitate considerations of climate change in...
Fish and wildlife science in support of heritage preservation, efficient decision making, wild ungulate management, and outdoor recreation
FORT researchers provide sound science to support the Department of Interior in its efforts to preserve American heritage, streamline species listing decisions and promote species recovery, manage wild horses and burros using efficient, cost-effective tools, and sustain hunting and fishing on public lands. This research is developed in partnership with resource managers from local, State, Federal...
Invasive species science in support of public safety, America’s natural resources, and economic growth
FORT invasive species researchers provide sound, reliable science to support the Department of the Interior in its goals of ensuring public safety and security, protecting America’s lands and waters, and aiding economic growth. This research is developed in partnership with resource managers from local, State, Federal and Tribal governments, industry, and nongovernmental organizations, empowering...
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.
Hierarchical Units of Greater Sage-Grouse Populations Informing Wildlife Management
Wildlife management boundaries often lack biological context, including information on habitat resource availability and wildlife movements. To address this, we developed multiple levels of biologically relevant and hierarchically nested greater sage-grouse ( Centrocercus urophasianus) population units to facilitate the management and conservation of populations and habitats.
Short Science Syntheses and NEPA Analyses for Climate-Informed Land Management Decisions in Sagebrush Rangelands
The Bureau of Land Management (BLM) manages the largest area of public lands in the United States. Decision-making on BLM lands is complex because managers have to balance diverse, sometimes conflicting, resources, uses, and values. Land managers are more likely to achieve long-term land management goals and balance multiple desired uses and values across public landscapes when their...
Providing a Climate Science Foundation for Updating the Integrated Rangeland Fire Management Strategy Actionable Science Plan
The long-term success of management efforts in sagebrush habitats are increasingly complicated by the impacts of a changing climate throughout the western United States. These complications are most evident in the ongoing challenges of drought and altered rangeland fire regimes resulting from the establishment of nonnative annual grasses. The Integrated Rangeland Fire Management Strategy
Contributions to the development of the Western Association of Fish and Wildlife Agencies Sagebrush Conservation Strategy
USGS scientists are contributing to the development of the Western Association of Fish and Wildlife Agencies Sagebrush Conservation Strategy, a strategy intended to provide guidance so that efforts to conserve the iconic greater sage-grouse can be expanded to the entire sagebrush biome to benefit the people and wildlife that depend on it.
Annotated Bibliography of Scientific Research on Greater Sage-Grouse
The greater sage-grouse has been a focus of scientific investigation and management action for the past two decades. The sheer number of scientific publications can be a challenge for managers tasked with evaluating and determining the need for potential updates to existing planning documents.
A Climate Vulnerability Assessment Framework for Data-Poor Species
Assessing the vulnerability of species to climate change is a key step in anticipating climate impacts on species. Vulnerability assessments characterize species’ future conservation needs and can guide current planning and management actions to support species persistence in the face of climate change. A full assessment of climate vulnerability involves characterizing three essential...
