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.

Environmental groups in Arizona say they've faced challenges in advancing environmental protections, and that could now become even harder under a second Trump presidency.
Sandy Bahr, director of the Sierra Club's Grand Canyon Chapter, said during his first presidency, Donald Trump rolled back a number of environmental rules, withdrew from the Paris Agreement and deepened reliance on fossil fuels. She expects Trump to disrupt clean-energy and climate-action progress made under the Biden administration.
"There is a big concern that President-elect Trump will try to reverse full throttle. I don't think he will be able to do that because there will be, at least on some things, enough bipartisan support that he won't be able to just get rid of everything," Bahr explained.
Bahr added while the Inflation Reduction Act will likely be a target for the incoming administration, it is important to remember much of the funds in the legislation have already been allocated to help communities make clean-energy investments.
Bahr said Arizona is already experiencing hotter and longer summers and that could intensify if not addressed, translating to higher energy bills and more deaths each year from the extreme heat.
"The cost of not doing something is much greater than the cost of doing something. Not to mention that clean energy, solar and wind, they're cheaper than fossil fuels. So economically, it just makes sense to do that," she continued.
The transition to clean energy will save the average family up to $7,200 per year in energy costs and another $1,500 per year in health-care costs, according to the Sierra Club.
Bahr says investing in clean energy and climate action goes beyond securing a prosperous future for humans, but encompasses habitat conservation and preservation for species of all kinds.
"One election does not mean that we are not on the right track with what we are asking for. Don't take it as a repudiation of everything that you believe in," she concluded.

As Minnesotans click the "purchase" button when shopping online for the holidays, they're urged to consider two things: toys from overseas suppliers that don't meet safety standards and how e-commerce affects the environment. In its annual toy safety report, the U.S. Public Interest Research Group says loopholes in shipping enforcement allow too many unsafe and illegal products, including those designed for kids, to flood the market.
Teresa Murray, PIRG's consumer watchdog director, said items shipped in bulk that fall below a certain value threshold often avoid scrutiny from U.S. customs officials, and that means for now, shoppers have to be extra vigilant.
"We've also gotten used to how easy it is to shop online, but when people are shopping online, they just need to be super, super careful. Take a few minutes and figure out where that toy is coming from," she said.
Murray added that there are concerns about some toys containing lead or other toxins or having small parts that easily break off, and added that the good news is, there's a bipartisan tone in Washington, D.C., to address the issue. Meanwhile, sustainability experts warn the massive growth in e-commerce leads to more distribution centers in rural areas, increasing trucking distances and exacerbating carbon emissions.
Another concerning trend in the report is the persistent illegal online sales of recalled toys. Murray said brick-and-mortar retailers are more committed to keeping those items out of circulation. Beyond protecting your family and the environment, she suggests replacing digital purchases with in-person shopping might help the economy, because you're fighting back against counterfeit products.
"Frankly, it hurts U.S. companies and U.S. workers when you have these brands that have built a reputation and somebody - you know, it could be domestic, it could be international - and they're making a product that looks just like yours," she explained.
As for e-commerce waste, Minnesota recently adopted a law that incentivizes producers to scale down their use of packaging that often ends up in landfills. A handful of other states have taken similar steps. And online shopping giants like Amazon have highlighted efforts to phase out packaging elements deemed unfriendly to the environment.

A nonprofit group that tracks oil and gas development has created an interactive map to show how close CO2 pipelines in Great Plains states come to environmentally and ecologically sensitive areas.
The map includes Indigenous land that hasn't been included in similar previous projects.
Ted Auch, Midwest program director for the FracTracker Alliance, said it focuses on Indigenous areas but goes further, showing in detail how close proposed CO2 pipelines would come to soybean and ethanol facilities, for example, but also to private land.
He said the interactive map is an improvement over existing ones.
"Which is to say that you could look at it as a static image, but you can't interact with or manipulate the data in terms of, like, scrolling in, scrolling out, finding addresses - you know, that kind of thing," said Auch. "It's available as a PDF or a JPG. So, what we've done is, we've taken that stuff and we've digitized it and we've included it on this map, so that people can actually - spatially and in real time - interact with the data itself."
The Great Plains Action Society says CO2 pipelines pose risks that disproportionately affect Indigenous communities and people of color.
Auch said FracTracker is working on another version that takes a deeper look at the proximity of pipelines to the Winnebago reservation south of Sioux City.
Energy companies say the pipelines are a safe and effective way to capture carbon from industrial processes, and store it underground, reducing greenhouse gas emissions.
Auch said the interactive map will give farmers and other landowners near the proposed pipelines what they need to understand what's happening on their land, leveling the information playing field with corporate interests.
"You have these large, multinational corporations, and then on the other side of the ledger are small, medium-sized frontline or Indigenous groups that either have small budgets or no budgets," said Auch, "and don't have the capacity, the time, or the expertise to develop maps to inform their organizing activism or advocacy."
The Eighth Circuit Court of Appeals in Omaha is making a livestream available as it hears oral arguments today in a case involving Iowa landowners affected by CO2 pipeline proposals, some of whom face seizure of their property by eminent domain if the Summit Carbon Solutions project moves forward.
