The wildlife camera footage showed sheep grazing on vegetation beneath the solar panels. It also revealed that they were just one part of an ecosystem operating beneath the array.
It appears as if the sheep have been assigned a very basic maintenance task – to keep the vegetation down.
In addition to documenting the actions of the sheep, researchers also installed various forms of monitoring equipment in multiple areas of the site.
Those wildlife cameras revealed that the sheep were only part of a much larger story beneath the solar arrays.
More than a simple grazing operation
Happy Solar Farm was designed as an agrivoltaic project, allowing the land to serve another purpose. The 95 MW facility is planted with native wildflowers that support monarchs and other pollinators. In the summer, a flock of sheep graze between each row of panels.
These animals reduce the need for mechanical mowing, return nutrients to the soil, and help manage weeds.
The combination of pollinator habitat and sheep grazing made the site unusual among utility-scale solar projects.
Researchers wanted to determine whether wildlife communities differed between native and conventionally managed solar sites. Scientists still knew relatively little about how wildlife responds when solar farms become part of a larger habitat. That left unanswered questions about how different animals use solar farms across an entire region.
The University of Arkansas launched a study that included over 90 solar sites in Arkansas and surrounding states.
Wildlife cameras, acoustic recorders, and on-site samples documented wildlife around the panels.
The cameras kept finding more activity
They wanted to see whether wildlife responded differently when solar sites were managed in different ways.
Some of the sites contained native vegetation, while others were managed more conventionally.
Nearby agricultural land provided a reference point for understanding how wildlife used the area before solar development.
Happy Solar Farm, operated by JERA NEX, became one of the study’s key comparison sites because it combined pollinator habitat with managed sheep grazing.
The team used the site to examine how pollinator plantings and grazing shaped animal activity beneath operating solar arrays.
The monitoring effort quickly began to record far more than just grazing sheep. The cameras captured activity throughout different parts of the site rather than around a single location.
Some species appeared to be sheltering, while others were using the habitat to hunt or forage. The findings pointed toward interactions between species rather than isolated wildlife sightings.
A food web emerged beneath the panels
Mammals, birds, butterflies, amphibians, and reptiles were documented throughout the study sites using wildlife camera photographs.
Wildlife observed during the study included frogs, snakes, monarch butterflies, Slender Glass Lizards, Ornate Box Turtles, Upland Sandpipers, and the rare American Badger.
The “feast” described by the headline was not a single feeding event. Rather, it represented a food web established beneath the panels. Wildflowers supported a multitude of insects and other small animals.
Those conditions drew in frogs, reptiles and other prey species. Predators such as snakes and badgers began to utilize the location where food became available.
Ultimately, the combination of wildflowers, sheep grazing and minimal disturbance created enough food to support multiple layers of the food web.
What happens at the remaining study sites
Data from the remaining sites will show whether similar wildlife patterns appear across other solar installations in the study.
Results from this study should help guide future wildlife-friendly solar projects.
Researchers are now watching to see which management approaches consistently attract the greatest diversity of species beneath solar arrays.
In the North Sea, researchers discovered that a prehistoric-looking fish had begun building its own reef beneath a floating wind farm.
