Pronghorns Impacted by Solar Farms

Scientists Fit 75 Pronghorns, Fastest Land Animal in Americas, with GPS Collars: What They Found
The intersection of conservation and renewable energy is a complex one, where competing priorities and unexpected challenges often arise. A recent study in New Mexico has shed light on the impact of solar farms on pronghorn migration patterns using GPS collars. The findings suggest that it’s not the solar panels themselves causing problems, but rather the fences surrounding them.
The San Juan Solar and Storage Project, a 1,100-acre facility near a retired coal-fired power plant, is at the center of this research. In 2024, scientists fitted 75 female pronghorns with GPS collars to track their movement patterns in unprecedented detail. The results indicate that the fences surrounding the solar facility are disrupting ancient migration routes used by these iconic animals.
Pronghorns, often referred to as the fastest land animal in the Americas, are notoriously difficult to corral due to their tendency to crawl underneath fences rather than jumping over them like deer. This makes the six-foot chain-link fences around solar facilities a significant barrier for pronghorns.
Researchers are not advocating for the abolition of renewable energy projects in favor of fossil fuels; instead, they suggest that small design changes could make a big difference in allowing pronghorns to continue using their traditional migration routes. For example, raising the bottom of fences high enough for these animals to crawl underneath could be a simple yet effective solution.
Previous research has shown similar problems with solar farms and wildlife movement. A 2022 study published in Ecological Solutions and Evidence found that pronghorn activity declined significantly near a solar farm in Wyoming, with effects extending beyond the fenced area itself. It’s clear that more attention needs to be paid to the infrastructure surrounding renewable energy projects.
Considering ecosystem impact when building large-scale infrastructure is crucial. This may require rethinking design priorities: rather than just focusing on efficiency and cost-effectiveness, project planners should also take into account the needs of local wildlife. The pronghorns of New Mexico serve as a reminder that the natural world is inherently complex and unpredictable; by acknowledging this complexity, we may find more effective solutions to our problems.
As researchers continue to collect data on the San Juan Solar project, it’s clear that adaptation will be key. Scientists and policymakers must work together to develop innovative solutions that balance human needs with pronghorn well-being. The next chapter in this story will be all about collaboration between humans and wildlife.

It's time for renewable energy projects to get creative with their fencing. While it's encouraging that researchers are exploring ways to minimize disruption to pronghorns' migration routes, I'm still concerned about the bigger picture: how these solutions will scale up to meet growing solar farm development in the West. The six-foot fences may be a fix for this particular study site, but what about larger facilities with more extensive fencing needs? We need innovative solutions that can adapt to different landscape conditions and project sizes, rather than piecemeal fixes.

The unintended consequences of our pursuit of renewable energy are a sobering reminder that progress is rarely straightforward. While it's heartening to see researchers exploring solutions to mitigate harm to pronghorns, let's not overlook the broader implications of fencing off vast swaths of land for human interests. What about other species? How will these solar farms impact the delicate balance of ecosystems in areas where multiple species rely on the same migration routes? We need a more holistic approach to environmental conservation and infrastructure development – one that prioritizes coexistence rather than sacrificing native wildlife for the sake of efficiency.

The inconvenient truth about solar farms is that they're often built with little regard for the long-term impact on local wildlife. While this study highlights the need for more humane fencing designs, it's worth noting that not all pronghorn populations are affected equally. The San Juan Solar and Storage Project, being a large facility, may have different implications than smaller operations scattered throughout New Mexico. What about those pronghorns that don't migrate through designated corridors? Can we assume their routes will be similarly disrupted by lesser-known solar farms dotting the landscape?
