Action timeline

February 28, 2000 – The Center and the Pacific Rivers Council submitted a formal petition to list the Yosemite toad under the Endangered Species Act. The U.S. Fish and Wildlife Service issued a finding that the petition presented substantial information indicating listing might be warranted.

May 31, 2001 – The Center filed suit against the Service for stalling Endangered Species Act protection for the Yosemite toad. The Service was ordered by the Northern District Court to make a final listing determination for the species.

December 10, 2002 – The Service declared that although the toad warranted listing as an endangered species, it would not issue a listing proposal because of "higher priority" listings. Instead, the species was placed on the "warranted-but-precluded" list to remain a candidate for listing.

July 15, 2009 – The Center and other conservation groups offered a $1,500 reward for information leading to the identification and conviction of dirt bikers who damaged Groundhog Meadow in the Sierra Nevadas — vital habitat for the Yosemite toad.
