Projects and Research

Seasonal biological science technician Kelsey Loverink is the project lead for the Refuge's invasive plant species program. In this photo, Kelsey stands next to a mature invasive musk thistle while she sprays the plant's rosettes, which would become next year's mature plants. Mature musk thistle plants, as seen in this picture, simply have their flower heads removed to prevent seeding. This strategy effectively controls their spread without herbicide use since these plants are biennial and are at the end of their life cycle when in flowering stage.​​​​

Some of the recent and ongoing Refuge research projects include:

  • Integrated restoration strategy for cheatgrass in sagebrush sagebrush
    The western United States’ sagebrush country encompasses over 175 million acres of public and private lands. The sagebrush landscape provides many benefits to our rural economies and communities, and it serves as crucial habitat for a diversity of wildlife, including the iconic greater sage-grouse and over 350 other species.

  • Impacts of cheatgrass on sagebrush songbirds and their habitat
  • Nesting ecology of trumpeter swans
  • Breeding ecology of sage-grouse in southwestern Montana
  • Restoration of sagebrush meadow habitats
  • Linking beaver dam affected flow dynamics to upstream passage of Arctic grayling winter survival, resource use, and hypoxia impacts to Arctic grayling in Upper Red Rock Lake
  • Mountain camera trap surveys for carnivore inventory
  • Mountain bluebird nest box trail
  • Invasive plant removal for enhanced wildlife habitat
  • Aspen reforestation 
  • Duck banding
  • Effects of grazing on grassland and shrubland vegetation and bird communities
  • Grassland restoration
Five acres were restored in a field formerly inundated with invasive grasses at Red Rock Lakes National Wildlife Refuge. Eight species of native grasses and twelve species of native flowering forbs combining with some already present native forbs are expected to provide improved habitat for pollinators, birds, and mammals. In addition to returning this field to its fully functioning ecosystem state, it may also serve as an environmental education and interpretive site.

USFWS Zone Wildlife Biologist and proud father, Jeff Warren, poses with his daughters while holding lesser scaup ducks captured during banding operations on Lower Red Rock Lake at Red Rock Lakes National Wildlife Refuge. Waterfowl banding provides critical information when hunters harvest and report banded birds. Biologists use this information to make informed decisions governing conservation efforts of these species. Photo by Cortez/USFWS.
Deputy Refuge Manager Cortez Rohr delivers bags of whitebark pine cones to a member of the Montana DNRC Tree Seedling Nursery in Missoula, MT that he and technicians collected. The DNRC nursery in Missoula is standing up a whitebark pine seedling propagation program that currently only exists in Coeur d'Alene, ID. This program will be only the second of its kind and these are the first and currently only whitebark pine seeds the nursery is working with. In two years, the Refuge will have whitebark pine seedlings to plant on its high elevation mountain boundary. Photo by Cortez/USFWS.

While checking remote camera traps in the mountains for a Refuge carnivore inventory, USFWS Volunteer Sam Waller found a displaced camera trap that was buried in mangled and downed timber caused from a massive winter avalanche. The camera was carried 86 yards away from its original placement. Thanks for finding that camera for us, Sam! Photo by Cortez/USFWS.

Deputy Refuge Manager Cortez Rohr holds a flat containing whitebark pine seedlings propagated from cones he and technicians collected the previous year. The Missoula, MT DNRC tree seedling nursery is standing up a new whitebark pine conservation program in efforts to help save this keystone species. 50 whitebark pine seedlings will be planted on the Refuge's high elevation mountain boundaries while hundreds of other seedlings will be studied for blight resistance and planted in test plots throughout Montana. Pardon the blurry spot on the photo - it was humid in the nursery. Photo by Cortez/USFWS.

Volunteers, technicians, and Refuge staff pose for a picture after planting over 1700 aspen tree seedlings in two exclosures totaling five acres in size at a Refuge timber improvement project site to facilitate Wildland Urban Interface. The timber improvement project will help mitigate wildfire dangers near the Refuge headquarters. Aspen seeds were hand collected from six different mother trees around the Refuge and propagated into 12"-18" seedlings by the Montana Dept. of Natural Resources and Conservation tree seedling nursery. Many thanks to the volunteers and all who volunteered their time and efforts on a chilly snowy mid-May to plant tree seedlings. Photo by Cortez/USFWS.
2022 USFWS biological science technician Jennifer Baxter measures willow browse in the Refuge's willow fen along a survey transect. Data collected will help assess browse pressure exhibited by moose. Given that willows provide important habitat for songbirds and are food resources for several animal species including moose, understanding browse impact is important in determining willow community health.

2021 USFWS seasonal technicians Taelyn Cathcart, AJ Temple, and Aidan Sullivan identify different species of willows and perform browse surveys to assess the level of moose herbivory, its effect on overall willow community health, and subsequent trickle down ecosystem effects.

Former Refuge biologist Kyle Cutting hand augers a hole in 35" thick ice on Upper Red Rock Lake to measure late winter oxygen levels. This effort is to learn more about the Refuge's threatened adfluvial Arctic grayling population and how winter habitat conditions limit the fish's ability to overwinter. Photo by Cortez/USFWS.
