LITIGATION
On 7/26/11, oral arguments were presented to U.S. District Judge Donald Malloy. Four environmental groups challenged the constitutionality of the congressional rider [authored by U.S. Senator Jon Tester (D-Montana) and U.S. Representative Mike Simpson (Republican-Idaho)] which directed the USFWS to reissue its 2009 delisting rule. A decision from Judge Malloy is pending.

MONITORING
Through the end of July, at least 19 packs are confirmed or suspected to have produced pups in 2011 in Wyoming (outside Yellowstone National Park).
