Jill Hardiman
Hello welcome to my professional page. I have been working in the field of fisheries biology for over 20 years. Most of my career has been with the USGS either as an employee or contractor. I have also worked as a fisheries observer for NMFS program many years ago as well as completed my Master's degree and research and teaching related responsibilities at Colorado State Univ.
Research Interests:
My interests lie in ecosystems change as it relates to large landscape scales stressors such as climate change, land use/development and invasive species. My areas expertise include Geographic Information Systems (GIS), data management, project management, monitoring and habitat assessments, and salmonids.
Major Projects: Regional coordination of monitoring efforts for invasive mussels in the northwest states based on prior risk assessment models and sample design for local efforts; Predator/prey study of juvenile salmon consumption by native and non-native species; bioenergetics modeling of the effects of climate change on the growth of fish; development of a probabilistic based sample design framework for Columbia and Snake rivers status and trends monitoring; invasive species surveys and habitat assessments in the Columbia River and tributaries. Past team leader of a telemetry (hydroacoustic and radio) project evaluating the effects of juvenile salmonid passage histories at hydroelectric dams in the Snake River on their survival to McNary Dam, Columbia River, as well as various juvenile salmon survival studies for the Lower Columbia River dams. Primary responsibilities:
- Prepare professional presentations, reports, research proposals, and manuscripts
- Project design, field and lab oversight, and project reporting and communication of results
- Database management and analyses
- Create Statistical Analysis Software (SAS) programs to manipulate and analyze large databases
- Prepare Geographic Information Systems (GIS) databases, maps for study design, presentations, and analyses
- Design and conduct invasive species surveys with global positioning system (GPS) and GIS focusing on habitat strata and a probabilistic sample framework
- Develop and implement Quality Assurance Plans for research projects
- Attend regional meetings, communicate research, and provide technical reviews.
Science and Products
Rock Creek Fish Population and Life History Assessment (Washington)
The research conducted by the U.S. Geological Survey, in coordination with the Yakama Nation, is designed to determine stream habitat conditions, fish abundance, and fish life history characteristics such as movement, growth, and distribution.
Steelhead Life History Study in White Creek on the Yakama Nation Reservation
Fishery biologists from the U.S. Geological Survey have teamed with fishery biologists from the Yakama Nation to conduct a life history study of the juvenile steelhead using small electronic tags.

Climate Change Threats to Fish Habitat Connectivity
Many fish species, including mountain whitefish and bull trout, need a variety of habitat types throughout their different life stages that include appropriate water temperatures, flows, refugia from predators, and adequate food. Key to a fish finding and using these different habitats is the connectivity between them. Changing conditions in the future, including increased air and water temperatur
