The Nature Conservancy’s Current Research Projects
in Centennial Valley
- Vegetation monitoring on conservation easements: photo monitoring, frequency plots,
residual cover to assess the effects of grazing on plant communities
- Monitoring on Sandhills Preserve for rare plants, effects of management experiments
(grazing, fire, hand treatments), rare insects, invertebrates
- Residual cover data collection and analysis
- Conifer encroachment mapping and treatments in sagebrush steppe
- Mapping, treating and monitoring invasive weeds throughout the valley
- Monitoring aspen plots for the effects of browse, wildfire, and conifer competition
- Measuring the effects of deformable shallow aquifer recharge structures and “beaver
mimicry structures” on Long Creek and Middle Creek
- Stream flow, photo point and pebble count monitoring on Long Creek and Hell Roaring
- Groundwater monitoring on Long Creek
- Supporting Range Rider program to monitor & reduce predator/livestock interactions

up RR creek.
Sponsored by the Refuge (Kyle Cutting), study design by Rebecca Levine of U of MT
Western. Michelle Anderson of U of MT Western also an advisor and co author.
- Research on genetics of Arctic grayling in various streams in the Valley as proxy
for how this species uses the landscape.
MTFWP with assistance in data collection from USFWS
- Research on how beaver dams have influenced Odell Creek channel development over time
and pre history using carbon dating.
Led by Rebecca Levine as PhD project, U of New Mexico, Funding from National Sci Foundation
and support of the Refuge.
- Many projects are also ongoing in the arena of "land management, restoration, fish
passage, population management, range management, forest management and wetland management.
