  • Big Hole River Fluvial Arctic Grayling
    FLUVIAL ARCTIC GRAYLING MONITORING REPORT 2003 James Magee and Peter Lamothe Montana Department of Fish, Wildlife and Parks Dillon, Montana Submitted To: Fluvial Arctic Grayling Workgroup And Beaverhead National Forest Bureau of Land Management Montana Chapter, American Fisheries Society Montana Council, Trout Unlimited Montana Department of Fish, Wildlife, and Parks U. S. Fish and Wildlife Service June 2004 ACKNOWLEDGMENTS The following individuals and organizations contributed valuable assistance to the project in 2003. Scott Lula, Greg Gibbons, Zachary Byram, Tracy Elam, Tim Mosolf, and Dick Oswald of Montana Fish, Wildlife, and Parks (FWP), provided able field assistance. Ken Staigmiller (FWP) collected samples for disease testing. Ken McDonald (FWP), provided administrative support, chaired the Fluvial Arctic Grayling Workgroup, reviewed progress reports and assisted funding efforts. Bob Snyder provided support as Native Species Coordinator. Dick Oswald (FWP) provided technical advice and expertise. Bruce Rich (FWP) provided direction as regional fisheries supervisor. Jim Brammer, Dennis Havig, Dan Downing, and Chris Riley (USFS) assisted with funding, provided housing for FWP technicians, and assisted with fieldwork. Bill Krise, and Ron Zitzow, Matt Toner, and the staff of the U.S. Fish and Wildlife Service (USFWS) Bozeman Fish Technology Center maintained the brood reserve stock and transported grayling to the upper Ruby River. Jack Boyce, Mark Kornick and Jim Drissell, and crew of Big Springs Hatchery assisted with egg takes at Axolotl and Green Hollow II brood lakes, and transported eyed grayling eggs for RSI use in the upper Ruby River and to Bluewater State Fish Hatchery for rearing reaches. Gary Shaver, Bob Braund, and Dave Ellis from Bluewater State Hatchery raised and transported grayling to the Ruby River and the Missouri Headwaters restoration reaches.

  • Memorandum of Understanding Concerning Montana Arctic
    Memorandum of Understanding Concerning Montana Arctic Grayling Restoration August 2007 1 MEMORANDUM OF UNDERSTANDING among: MONTANA FISH, WILDLIFE & PARKS (FWP) U.S. BUREAU OF LAND MANAGEMENT (BLM) U.S. FISH & WILDLIFE SERVICE (USFWS) U.S. FOREST SERVICE (USFS) MONTANA COUNCIL TROUT UNLIMITED (TU) MONTANA CHAPTER AMERICAN FISHERIES SOCIETY (AFS) YELLOWSTONE NATIONAL PARK (YNP) MONTANA ARCTIC GRAYLING RECOVERY PROGRAM (AGRP) USDA NATURAL RESOURCE CONSERVATION SERVICE (NRCS) MONTANA DEPARTMENT OF NATURAL RESOURCES AND CONSERVATION (DNRC) concerning MONTANA ARCTIC GRAYLING RESTORATION BACKGROUND Montana’s Arctic grayling Thymallus arcticus is a unique native species that comprises an important component of Montana’s history and natural heritage. Fluvial (river dwelling) Arctic grayling were once widespread in the Missouri River drainage, but currently wild grayling persist only in the Big Hole River, representing approximately 4% of their native range in Montana. Native lacustrine/adfluvial populations historically distributed in the Red Rock drainage and possibly the Big Hole drainage have also been reduced in abundance and distribution. Arctic grayling have a long history of being petitioned for listing under the Endangered Species Act (ESA). Most recently (in April 2007) the U. S. Fish and Wildlife Service (USFWS) determined that listing of Arctic grayling in Montana under ESA was not warranted because it does not constitute a distinct population segment as defined by the ESA. On May 15th 2007, the Center for Biological Diversity announced its 60-day Intent to Sue the USFWS regarding the recent grayling decision. The Montana Arctic Grayling Recovery Program (AGRP) was formed in 1987 following declines in the Big Hole River Arctic grayling population, and over concerns for the Red Rock population.

Compiling information to better understand the water and fishery resource is intended to help citizens in the valley make decisions on the fate of the Jefferson River. Once dubbed the “Forgotten Fork” of the headwaters of the Missouri, the past eight years of citizen involvement to protect and improve habitat have raised the profile of the river, and it is clear that the river can no longer be considered forgotten or dismissed.
