Fluvial Arctic Grayling
Conservation Efforts on Private Lands
The
distinct population segment of fluvial Arctic grayling in the upper Missouri
River has been an ESA candidate since 1994. The sole remaining population
exists in the Big Hole River in southwestern Montana and represents only
about 5% of the historic range.
Grayling conservation efforts in the Big Hole
River are ongoing, and a pending umbrella Candidate Conservation Agreement
with Assurances (CCAA) that encompasses the core of the population in the
drainage is the centerpiece of these efforts. The CCAA is being developed
collaboratively by Montana Fish, Wildlife and Parks (FWP), Montana
Department of Natural Resources and Conservation, Natural Resources
Conservation Service and the Service’s Endangered Species staff. The
proposed CCAA focuses on working with landowners to reduce irrigation
diversions and improve instream flows, conserve or restore riparian habitat,
assess and mitigate entrainment in irrigation ditches, and remove barriers
to grayling movement in natural stream channels. We anticipate finalizing
the CCAA and issuing the permit in Spring 2006.
