The Trump administration is delaying construction on its long-promised border wall that would cut through protected stretches of the Arizona desert.

The Navajo Nation has decided to stop pursuing the acquisition of a beleaguered coal-fired power plant in Arizona, locking in the plant to be taken offline and its associated coal mine to close later this year.
A Navajo Nation Council committee voted 11-9 last week to stop pursuing the purchase of the 2,250-megawatt Navajo Generating Station, which with the Kayenta coal mine provides more than 800 jobs to primarily Navajo and Hopi workers as well as tribal royalties.
A coalition of utilities that own the plant said in 2017 it would cease operations due to increased economic pressure, and the plant's future has proved a flash point for national and regional energy policy and raised larger questions on how Native communities will handle ties to fossil fuel industries as the economy changes.

Conservation groups filed a lawsuit Thursday challenging the U.S. Army Corps of Engineers' approval of a permit that allows a huge master-planned sprawl development project near Benson, Arizona to proceed. The Villages at Vigneto would transform 12,167 acres of largely undeveloped habitat into 28,000 residences, 3 million square feet of commercial space, four golf courses, fountains, lakes and a resort.

The Trump administration's decision to keep many U.S. national parks open during the current federal government shutdown, with few or no staff, spotlights how popular and how vulnerable these unique places are.
Some states, such as Utah and Arizona, have spent heavily to keep parks open rather than lose tourist revenues. Unfortunately, without rangers to enforce rules, some visitors have strewn garbage and vandalized scenic areas.

In the last few weeks of 2018, the Trump administration set the stage for a big battle over water in the new year. At stake is an important rule that defines which waters are protected under the Clean Water Act. The Trump administration seeks to roll back important protections for wetlands and waterways, which are important to drinking water and wildlife.

Despite the Trump administration's ongoing attempts to prop up coal and undermine renewables—at FERC, EPA and through tariffs and the budget process—2018 should instead be remembered for the surge in momentum toward a clean energy economy. Here are nine storylines that caught my attention this past year and help illustrate the unstoppable advancement of renewable energy and other modern grid technologies.
A little less than a week after the midterm election, Democrat Kyrsten Sinema has edged out Republican Martha McSally to become Arizona's first female Senator and the first openly bisexual member of Congress, The Guardian reported. She is the first Democrat to win an Arizona Senate seat since 1976.
Results from the U.S. midterm election are mostly in, and, when it comes to what they mean for the environment, they're a real mixed bag.
Scientists at Northwestern University and the Chicago Botanic Garden conducted a two-year study of the blueberry mason bee (Osmia ribifloris) native to the Western U.S. and Northern Mexico. They found that, when a group of bees was exposed to temperatures predicted for Arizona from 2040 to 2099, 35 percent of them died off the first year and 70 percent the year after, a Northwestern University press release reported.
A new Trump administration plan proposes to auction off 4,200 acres of public land for oil and gas development in northern Arizona. The lands straddle the Little Colorado River, are within three miles of Petrified Forest National Park, and are near habitat for a federally threatened fish called the Little Colorado spinedace. Drilling and fracking would threaten to deplete and pollute groundwater in the Little Colorado River Basin.
