Report shows sage grouse tolerance for disturbance is very low

A report by the U.S. Geological Survey documents how much human disturbance sage grouse can tolerate, and report co-author Steve Knick says the amount is very low.

He says most active leks, or breeding grounds, are in areas where less than three-percent of the land is developed.

Knick says the study shows that Wyoming is on the right track with its core area policy.

USGS study shows gas production can affect stream water

A new report by the U.S. Geological Survey finds that coal-bed natural gas production can affect water quality in nearby streams.

The study monitored water quality over a ten-year period in Wyoming and Montana, and found that in places like the Powder River, sodium levels increased. Other test sites showed little or no change in water quality.

Report author Melanie Clark says the changes occur because water that’s extracted during gas production sometimes flows into the streams and rivers.
