Large-scale ground-mounted solar installations can affect wildlife welfare positively and negatively depending on design, location, and management.
Solar farms present a more nuanced wildlife welfare picture than often portrayed. Poorly sited installations on biodiverse grassland or wetland habitat cause direct welfare harm through habitat destruction. However, solar farms on degraded agricultural land, managed with habitat-enhancing planting, can provide refuge for declining ground-nesting birds, invertebrates, and small mammals. The welfare outcome depends almost entirely on siting decisions and ongoing land management. Welfare-positive solar development requires careful site selection and active habitat management.
