A wildfire burning 40 miles northeast of Boise is moving away from structures, but continues to pour smoke into the Treasure Valley.

The 2,500-acre Walker Fire started Saturday on private property near Grimes Creek and Mack Creek. The fire is suspected to be human caused.

Burning eight miles southwest of Idaho City in Boise County, the fire has destroyed four structures, including three cabins.

The Idaho Department of Lands says some areas are still under evacuation:

Interior Secretary Sally Jewell announced the much-anticipated decision on Twitter Tuesday morning, using the hashtag #WildlifeWin.

“Because of an unprecedented effort by dozens of partners  across 11 western states," says Sec. Jewell in a video, "the U.S. Fish and Wildlife Service has determined that the greater sage grouse does not require protection under the Endangered Species Act.”

It is common knowledge that the drought this year was pretty bad. But just how intense was it, and what can we learn about it for future water supply shortages? These are some of the questions scientists with the U.S. Geological Survey across the West are asking. They are studying streams and rivers in six states, including Idaho, Oregon and Washington.

Over the last few months you’ve heard a number of reports about a species of bird that lives in Idaho and 10 other western states. The greater sage grouse is in the spotlight as the U.S. Fish and Wildlife Service decides whether the bird merits listing under the Endangered Species Act. If the grouse is listed, it could have devastating effects on the regional economy. 

The Idaho Department of Environmental Quality (DEQ) issued an alert Monday declaring air quality unhealthy again in the Treasure Valley. The agency issued a similar alert last Thursday.  

If your shortness of breath is giving you déjà vu, you’re not alone. This summer's smoke and wildfires are approaching the numbers put up in the summers of 2007, 2012 and 2013.

Smoke from wildfires continues to plague the Treasure Valley. Forecasters say things will get worse before they get better.

Winds are out of the northwest Friday and expected to be again Saturday. That will actually bring more smoke into the Treasure Valley.

Three firefighters died after their vehicle crashed and was likely caught by flames as they battled a blaze in Washington State yesterday. Four other firefighters were injured.

The National Interagency Fire Center (NFIC) says 13 people have died battling the fires this year.

Driving is one of the leading causes of death for wildland firefighters. That can include driving to or from a fire, as well as on the fire line.

Randy Eardley of NFIC says every death is mourned.

The accidental release of toxins into the Animas River in Colorado is a reminder of the long-term effects of mining. The decades-old gold mine had been dormant, but the toxins from the operation breached a dam there on the Environmental Protection Agency's watch.

Environmentalists around the West are pointing to the disaster, saying what happened in Colorado could happen in other states — including Idaho.

Smoky skies, from dozens of western wildfires, have prompted the Idaho Department of Environmental Quality to issue an air quality advisory for the entire state of Idaho.

Such advisories are typically issued for individual counties or cities.

The Soda Fire along the Oregon border has burned 440 square miles. The majority of those miles is rangeland in Owyhee County and that’s bad news for ranchers. There could be long-term effects to ranchers in the area.

More than 26 percent of jobs in Owyhee County come from agriculture, two-thirds of which comes from livestock operations. There are 145,000 cows in the county — 36,000 of them are beef cattle.

A new wilderness in Idaho is one step away.

The U.S. Senate on Tuesday passed a bill protecting 275,000 acres in central Idaho.

The U.S. House or Representatives passed similar legislation last week meaning it now goes to President Barack Obama for his signature.

The Obama administration set carbon dioxide limits for electric power plants Monday. The objective is to combat climate change by clamping down on power plant pollution, especially coal-fired electricity.

WildEarth Guardians accuses the Bureau of Land Management in Idaho of removing nearly 4 million acres from a previous plan to protect sage grouse habitat, and not being transparent about it. The environmental and wildlife advocacy group wants to see the threatened bird listed under the Endangered Species Act.

On July 8th, 1879, the USS Jeannette left San Francisco and sailed northward toward uncharted Arctic waters. Its ambitious destination: the North Pole, a place that had captured the imagination of 19th century scientists, explorers and the public, but that remained shrouded in mystery and wild scientific speculation. If the expedition succeeded, the American ship and its crew would be the first to discover what really existed at the top of the world.

When officials at the National Interagency Fire Service (NIFC) forecast the 2015 season, they made it clear that what we know of as “normal” in wildfires has shifted in recent years. Prolonged drought, larger and more difficult to manage fires, have become regular occurrences in the West.

Federal officials say that more than 90 percent of Idaho's counties have either been declared natural disaster areas or are bordering disaster areas because of prolonged drought.

The U.S. Department of Agriculture has designated Benewah, Bonner, Clearwater, Kootenai and Latah counties as the most recent regions to qualify as primary natural disaster areas.

The declaration means farmers and ranchers in those counties are eligible to apply for low interest federal emergency loans. Eligibility is open for eight months from the date of the declaration.

The Idaho Oil and Gas Conservation Commission has decided it won't use an option made available by lawmakers earlier this year intended to speed the commission's natural gas and oil decision making process.

The commissioners with the 3-0 vote on Wednesday chose not to use the option given to them by lawmakers earlier this year that allowed the commission to exempt itself from the contested case provision in Idaho law.

For as long as humans have walked the Earth, we’ve been making changes to it – oftentimes with little or no comprehension about the far-reaching consequences of our actions. But in her book, The Sixth Extinction: An Unnatural History, Elizabeth Kolbert opens our eyes to the powerful and possibly catastrophic mass extinction unfolding right in front of us.

Thursday night’s chemical bombardment of mosquitoes from a low-flying plane in Ada County went well before being interrupted by a storm. Weather permitting, the process will continue Friday night.

Brian Wilbur, Director of the Ada County Mosquito Abatement District, says the contracted plane sprayed parts of Star and Eagle around 10 p.m. Thursday. That gave the Dibrom Concentrate, which is a short-lived chemical, time to work before the rain moved in.

Idaho is among 12 states that will share $10 million from the Interior Department, which will be used to keep the threat of wildfire to a minimum in sensitive sage grouse habitat.
