Wildlife officials are reviewing 6 species

Federal wildlife officials are re-examining the status of six threatened or endangered species in Utah.

The U.S. Fish and Wildlife Service says it is reviewing the species to see whether they need more protection or less.

Included in the review is the June sucker, which is known to live only in Utah Lake and its tributaries. About $39 million has been spent trying to save the fish, which is classified as endangered.

The status of several plants in Utah will also be reviewed: the Barneby reed-mustard, Barneby ridge-cress, shrubby reed-mustard, clay reed-mustard and Maguire primrose.

The Endangered Species Act requires all listed species to be reviewed at least once every five years.
