Cute cactus alert! The Paradine plains cactus is also resilient, having survived a wildfire in the Grand Canyon North Rim last year. Now, researchers are studying whether this cactus can beat the slow squeeze of the drought after the scare of the fire. 📝 and 📸 by me for @azcentral.com:

A tiny cactus holds clues to forest recovery after Arizona wildfire

A new study will monitor surviving Paradine plains cactus north of the Grand Canyon for three years to measure the full impacts of the fires.

One of my favorite stories so far: After the end of the federal tax credits, what's up with rooftop solar? Turns out, the industry is still finding ways to keep on, and it has market forces on its side: rising energy prices. @azcentral.com @solarunitedneighbors.org @autumntjohnson.bsky.social

How solar energy co-ops can cut costs for Arizona homeowners

After federal tax credits for renewable projects expired, joining a solar co-op is one way to save on residential solar.

Introducing invasive fish for recreational fishing is wreaking havoc on Arizona's waterways. Native species already have to contend with drought. Now they're getting eaten to extinction. Experts say that the practice of fish stocking needs an overhaul. @azcentral.com @biologicaldiversity.org

Sport fish are crowding out native species, conservation groups argue

Stocked game fish have devastated aquatic wildlife, and conservation groups want to eradicate the invasive species and reintroduce native ones.

Last week, a friend and I planned to visit Sedona but were foiled by the #PocketFire. A week later, it grew 100 fold to ~10,000s of acres. Much of the Southwest is burning, and there's an glaring driver: climate change. Until humans get our act together, this still needs to be said. @azcentral.com

How climate change is driving Arizona's Pocket Fire and other blazes

Climate change brings warmer temperatures and drier weather — conditions favorable for a rapid spread of wildfires.

Come for the anecdote about Frankie, the calf with the blue eyes and boopable snout! He and his owners owe his existence to GPS technology and other tools. Ranchers in the Southwest borderlands are going hi-tech to combat drought and other tough challenges on a tough landscape. For @azcentral.com:

Smart sensors, GPS, AI help border ranchers survive Arizona's drought

Ranchers are leaning on GPS collars, remote sensors and artificial intelligence to ease the pains of a tough livelihood, one made worse by drought.

No matter where people fall on the political spectrum, Arizonans can agree that we all love nature here. Our top concerns for our forests are wildfire and recreation opportunities. The recent policy changes in the Forest Service hit these pain points, hard. Me for @azcentral.com:

Major Forest Service changes stoke concern amid AZ wildfire season

As Arizona heads into a potentially fiery summer, the U.S. Forest Service is dealing with budget cuts and new fire policies.

Over 150 definitions exist for the different manifestations of drought, and one of them is pretty gnarly to forecast. Can AI help predict the kind that grips waterways and staunches flow? Spoiler alert for my @azcentral.com piece: yes, AI improves on flow projections, but it's still a ways off.

A new AI tool could help predict drought on Arizona rivers. Here's how

Climate change is drying out rivers across the country. A new AI forecasting tool can help managers, governments and water users plan.

In March, I got to see a natural wonder unique to southern AZ: black hawk migration, with up to 100 of the birds flying over #Tubac daily. Their journey rests on the persistence of cottonwood trees along riparian corridors. For a drying, warming state, that future isn't guaranteed. @azcentral.com

Black hawks return to Arizona's Santa Cruz River for the habitat

As black hawks flock to Tubac, so too do birdwatchers. The monitoring effort provides a snapshot of health of the riparian habitat.

Takeover of federal lands could cost Arizona $800 million, study says

Managing federal lands could cost Arizona $800 million in lost funding, a new study concludes. Most of the cost comes from wildfire mitigation and suppression on wild lands across Arizona. Outdoor recreation is the most lucrative land use of public lands and far exceeds the tax revenues generated from industries like mining. A newly released report aims to remind people of the importance that public lands remain in federal hands, even as state lawmakers in several Western states continue to push plans to take over the resource. The report, released in conjunction with Arizona Public Lands Day, the first Saturday of April, pegs the economic cost of managing those swaths at $800 million a year, enough to bankrupt the state outright if Arizona took over managing federal lands within its boundaries. “A number of legislators seem to think that they could make a lot of money,” said study author Dave Wells of the Grand Canyon Institute. “They don't certainly fully recognize all of the federal dollars that come in to maintain the land.” A state takeover of federal lands would hit rural communities the hardest, block public access to recreation opportunities and likely anger many Arizona voters. Yet rollbacks in...

In the biodiverse grasslands of Southeastern AZ, generational ranchers here have learnt the hard way the importance of treading lightly on the land. Now, drought is threatening the delicate balance between cattle operations and the health of the landscape. Me for @azcentral.com:

Ranchers in southern Arizona live on the 'knife edge' of long drought

As summer rains vanish and dry conditions persist, borderland ranchers worry about their livelihood, culture and identity.
