The Fragment: April 2026 Policy Brief

Welcome to the third publication of The Fragment, our student voices platform! This policy brief was written by our dedicated and thoughtful Biodiversity Policy Interns, Jacob Pirosko and Arif G. The brief identifies conservation policy-relevant developments from the Avra Valley to Iran. Find Jacob and Arif's "key takeaways" throughout the brief that put developments into conservation context. At the end, they've articulated a key reason policy matters for biodiversity conservation. 

Executive Summary

• Pima County named a wildlife corridor in Avra Valley after University of Arizona Professor Emeritus William Shaw, recognizing his role in incorporating wildlife movement and habitat connectivity into local land-use planning and conservation efforts (1).

• Protestors in Tucson gathered to resist construction of Project Blue, a proposed data center, highlighting ongoing tensions between industrial development, water use concerns, and environmental advocacy (2).

• The Center for Biological Diversity launched a second lawsuit against federal agencies over continued livestock grazing damage along the Upper Verde River, arguing that insufficient enforcement threatens endangered species in key ecosystems (3).

• The Center for Biological Diversity filed notice of intent to sue federal agencies over a mining exploration project near Mammoth, Arizona, citing disturbances that threaten species such as Mexican spotted owls and yellow-billed cuckoos (4).

• The Trump Administration announced major restructuring changes to the U.S. Forest Service, including relocating headquarters, closing scientific research stations, and reducing staffing, raising concerns about weakened wildfire preparedness and reduced long-term ecosystem research (5).

• Increased pressure for offshore oil drilling along the California coastline has renewed environmental concerns due to risks posed to marine biodiversity and state park ecosystems following the legacy of previous major oil spills in the region (6).

• The USDA opened enrollment for the Grassland Conservation Reserve Program, which provides financial incentives for agricultural producers and landowners to conserve ecologically important grasslands (7).

• Environmental degradation tied to ongoing conflict in Iran has intensified drought, wetland loss, groundwater depletion, and contamination across the Gulf region, illustrating the relationship between geopolitical instability, ecosystem decline, and threats to human well-being (8).

Pima County

New Wildlife Corridor Named Honoring University of Arizona Professor Emeritus: The Pima County Board of Supervisors has voted to name a wildlife corridor in Avra Valley after University of Arizona Professor Emeritus William Shaw (1). He is known for being the first ecologist to include considerations for wildlife and their movement within their habitats in local land-use planning in Pima County (2). Shaw’s work will be honored at the 25th anniversary celebration of the Sonoran Desert Conservation Plan (3).

Key takeaway: Shaw’s work in Pima County is an excellent example of how to take steps forward toward a sustainable future while also encouraging urban development. Biodiversity needs to be accounted for in urban planning, as conservation can occur simultaneously with economic advancement. 

Tucson Protestors Gather to Show Resistance to Project Blue Data Center: Many protestors gathered at the Pima County fairgrounds to block construction crews from starting on Project Blue, a data center being built in Tucson (1). Despite the Tucson City Council voting against the project, Beale infrastructure has begun construction with a revised plan to use less water for industrial purposes (2). Continued resistance to Project Blue represents an ongoing struggle between data center development and environmental organizations.

Arizona

Second Lawsuit Launched to Protect Upper Verde River: The Center for Biological Diversity has launched a second lawsuit against the U.S. Forest Service and U.S. Fish and Wildlife Service to protect the Upper Verde River from livestock grazing and its damages (1). Despite the region being closed off to grazing, a biological survey revealed that damages have continued, proving there has been a lack of enforcement by the federal government (2). As cattle significantly alter streamside habitat, increased enforcement would give many endangered species that rely on the Verde River more room to recover.

Lawsuit Launched to Block New Arizona Copper Mine (1): The Center for Biological Diversity has filed a notice of their intent to sue the U.S. Bureau of Land management and the U.S. Fish and Wildlife Service over a mining exploration project near Mammoth, Arizona (1). The project has already commenced, bringing bright lights, helicopter surveys and loud noises which greatly threaten species in the surrounding habitats (2). The lawsuit specifically mentions Mexican spotted owls and yellow-billed cuckoos as being particularly vulnerable to disturbances from the operation (3).

Key takeaway: Stronger environmental oversight and species protection measures are especially needed in ecologically sensitive areas. Industrial operations can create impacts on surrounding ecosystems that extend beyond what current policies consider, highlighting the critical role of scientific research in shaping effective biodiversity policy.

United States

Trump Administration Amends the U.S. Forest Service: On March 31, the Trump Administration announced that it is making several changes to the U.S. Forest Service. These changes include moving the headquarters to Salt Lake City, closing 57 of its 77 scientific research stations, and eliminating many jobs in an attempt to downsize (1). The changes are aimed at making “a healthy and productive forest system that provides affordable quality lumber to build homes right here in America,” while moving leadership closer to the forests and communities it serves (2). Many are worried about the adverse effects of these changes, including decreased readiness to battle wildfires and the loss of long-term research on critical forest ecosystems within the United States (3).

California Continues to Fight Offshore Drilling: Exacerbated by the conflict in Iran, Washington has increasingly pushed for increased oil drilling off the coast of Santa Barbara, California. The pipeline has not been used since 2015, as a rupture created one of California’s worst oil spills, polluting a biologically rich habitat home to sea turtles, pelicans, seals, dolphins, and many species of fish (1). The Trump Administration has deemed drilling necessary to “national security”, attempting to increase domestic drilling to replace foreign oil backlogged by the Strait of Hormuz (2). Drilling along the California coastline would threaten several important species, while the pipeline’s route through multiple state parks could also put wildlife and habitats in those areas at risk. 

USDA Opens Grassland Conservation Program:  On April 30, the USDA announced that agricultural producers and private landowners can enroll in the Grassland Conservation Reserve Program, beginning on May 4, through May 26 (1). The program aims to balance agricultural production with the conservation of America’s ecologically significant grasslands (2). Agricultural producers who enroll receive economic incentives to conserve plant and animal biodiversity (3).

International

Conflict in Iran Increases Environmental Stress in West Asia: The conflict in Iran has exacerbated environmental degradation in the broader Gulf region. The region has been experiencing severe drought, as rainfall has declined, depleting Iran’s rivers and creating the need for water rationing (1). Similarly, many wetland ecosystems have completely dried up, and groundwater reserves have depleted rapidly, contributing to the decrease in street level by more than ten inches per year (2). Aerial bombings have also greatly increased the presence of environmental contaminants, detrimental to people and ecosystems alike (3). The conflict greatly threatens both humans and the ecosystems they depend on in West Asia.

Why Does Policy Matter for Biodiversity Conservation?

A Symbiotic Relationship: Human Development and Biodiversity Conservation

This month’s biodiversity policy stories showcase the complex relationship between human development and environmental conservation. Many of the examples illustrate what happens when policy prioritizes short-term economic or industrial advancement without fully accounting for ecological consequences. In Arizona, the mining industry often threatens species by disturbing their habitats, while offshore drilling proposals along the California coastline risk biologically rich marine ecosystems for the sake of briefly lowering gas prices in the United States. Both human populations and natural ecosystems are threatened by the conflict in Iran, highlighting the close connection between environmental degradation and risks to human well-being. However, in Pima County, the implementation of wildlife corridors shows that development and biodiversity protection can coexist when policy intentionally incorporates science and long-term planning. Biodiversity policy is not simply about restricting development, but about ensuring that economic and industrial growth do not come at the cost of the ecosystems that human communities rely on for resources, stability, and resilience.
