On an overcast November morning, volunteers got to work to restore local river flow.

Drought and decreasing water availability have been ongoing problems throughout Arizona. In Tucson, drought along with new land developments are causing decreases in vegetation and wildlife habitat.

Watershed Management Group is a Tucson-based nonprofit that aims to fix this problem. The group aids in local water conservation, land restoration and river flow. It holds regular events to help the environment such as cleanups, workshops, fundraisers and classes. The group has a club called the River Run Network, which includes a biweekly email with invitations to events like creek walks and family education days to help restore Tucson's heritage of flowing rivers.

Watershed Management Group worked to remove an invasive plant from a riparian area in the Tanque Verde community of Tucson on Nov. 18.

The species of grass Arundo donax, more commonly known as "giant reed," is an invasive species in Tucson's riparian ecosystem, the wetland area between a body of water and land. Invasive species in those areas are harmful to the ecosystem, wildlife and the city's groundwater supply.

"Arundo is one of the invasive species that we focus on removing," said Hannah Nuest, a program coordinator for the River Run Network. "It sucks up to three to four times the amount of water that native plants do, which affects groundwater levels and river flow."

Tucson's drinking water comes mostly from the Colorado River, which is experiencing decreasing water levels, and from groundwater. But those underground aquifers are fed with water from natural areas like riparian preserves, and invasive species like arundo compete for that water, cutting into Tucson's water supply

"Invasive species also cause problems for tree canopy coverage," Nuest said. "Trees like the cottonwood and the mesquite need water closer to the surface, so when that water's being used up, the number of trees can decrease, causing habitat loss, less shade, more pollutants and hotter temperatures."

Arundo removal also helps the local ecosystem with flood risk reduction, water quality improvement and increased river flow.

"Arundo comes from the Mediterranean and was brought to the Tucson area around the early 19th century for landscaping," said Jim Washburne, Watershed Management Group's senior project specialist.

When arundo grass is present, nutrients that usually travel downstream are blocked. This prevents other plants from growing along waterways, which increases flood risks and decreases habitat potential.

Complete removal of every arundo plant would be nearly impossible, but removing even a small amount is good for the ecosystem, Washburne said.

"We typically do this every week in Tanque Verde," Washburne said. "This is our most consistent environmental event. It's important for the community to get involved in taking care of the land they live on."

According to Tucson's One Water 2100 Plan, which is a new city plan to improve water delivery methods, riparian preserve restoration not only increases local tree canopy coverage but helps the local economy by helping with cooler temperatures, more trees and more diverse water delivery options.

"Riparian areas are integral to the health of Tucson's water supply and economy," Washburne said.

The Trump administration's long-term plan for artificial intelligence could have far-reaching environmental impacts across the country.

His strategy calls for the removal of land use rules considered prohibitive to the construction of AI data centers. Last year, then Gov. Eric Holcomb announced Microsoft would invest $1 billion to establish a new AI data center in Laporte to generate cloud computing infrastructure.

Ben Murray, senior researcher for the advocacy group Food and Water Watch, said fossil fuel plants are already being reopened to help meet high energy demands.

"We just need to be aware that anything that prolongs our reliance on fossil fuel is going to increase the problems that we're seeing from the climate crisis," Murray explained.

Murray argued high-tech progress should not come at the expense of increased household energy prices. Residents' support is low due to concerns about increased traffic and noise near the centers. The Trump administration said environmental and permitting regulations will only slow America's dominance in the AI field.

A report last year found emissions from data centers owned by Apple, Google, Meta and Microsoft were more than seven times higher than officially reported. Computer servers using AI require far more energy than those without. A ChatGPT query, for example, can use up to 10 times more electricity than a standard Google search.

"These companies can seem as if they're decreasing their emissions and meeting net-zero goals but in reality, the emissions are amping up faster than ever for these companies," Murray pointed out.

Murray noted the push for more data centers is already leading Big Tech companies to backtrack on their climate goals. It is possible to power AI services with renewable energy sources, he added, but doing so requires political will.

As of June 2025, a 1,200-acre corn and soybean field just outside of New Carlisle has turned into eight Amazon-led AI energy centers. The tech giant plans to construct a total of 30 at the site.

After one year, Washington's first comprehensive bee survey has documented 15 species that have never been collected in the state before.

The project is cataloguing native bees, which includes nearly all species in the state, but excludes honeybees.

Karla Salp is a communications consultant with the Washington State Department of Agriculture's Washington Bee Atlas program, which conducted the survey.

She said the data will serve as a baseline to track bee populations.

"The reason why this is happening in the first place is to answer the question, how are pollinators doing in Washington state?" said Salp. "And the answer is we don't know, because we've never actually looked at even what bees we have throughout the state."

Salp said the project also involves compiling a list of plants that each bee species pollinates so residents can make their yards more attractive to these beneficial insects.

As honeybee numbers continue to decline rapidly, Salp explained that native pollinators may become more important to Washington's agriculture.

"Knowing what native pollinators we have and how we can support them is really a sustainability issue" said Salp, "to make sure that whether we have honeybees here or not, there are options for pollination."

Volunteers collected over 17,000 bees on more than 600 different host plants.

Salp said the process of identifying them is slow because each one must be viewed under a microscope, and there is still considerable work to be done.

"We're expecting to find a lot more species" said Salp, "that are either rare or even new to the state. "

If people are interested in volunteering, an online application for the Bee Atlas program is available on the Washington State Department of Agriculture website.

The Trump administration wants to overturn a conservation rule that had garnered more public comment than any in U.S. history up until that time.

Commonly known as the Roadless Rule, the U.S. Department of Agriculture regulation prohibits road construction, reconstruction, and timber harvesting on nearly 60 million acres of national forest land.

Sarah McMillan - the senior attorney and director of the Wildlands & Wildlife Program at the Western Environmental Law Center - said before it was adopted in 2001, 1.5 million people submitted comments, with the vast majority in support of the rule.

"This was a rule that was carefully, thoughtfully developed," said McMillan. "There was a long process of inventorying these roadless areas and identifying these remote, often mature and old-growth trees. This didn't happen overnight."

A rollback of the rule would allow more logging and drilling on federal lands, which McMillan said would worsen climate change, harm wildlife & vital ecosystems, jeopardize water quality, and negatively affect recreational opportunities.

The Bush administration attempted to repeal the Roadless Rule in 2005, but lost in the courts.

In announcing the proposed rollback, U.S. Secretary of Agriculture Brooke Rollins claimed more logging would improve forest management, which would in turn decrease forest fires.

But McMillan said that argument is disputed in a 2020 Wilderness Society study that found just the opposite.

"The truth is, un-roaded areas burn at a significantly lower rate than areas with roads," said McMillan. "So, fires start near roads."

McMillan said it doesn't make sense to allow private developers to log more trees when the planet is undergoing a biodiversity and climate crisis - especially because old-growth trees create a buffer against climate change.

Forests cover almost 30% of New Mexico's land area.
