During pandemic lockdowns, scientists observed significant changes in wildlife behavior as human presence decreased across landscapes. A study published in Science analyzed GPS tracking data from 37 species, revealing that human presence alone affects how animals use space and resources, even without physical habitat modifications.

Researchers paired animal movement data with cellphone location data across the United States. Two-thirds of species showed altered movement patterns, with effects more pronounced in rural areas than cities. Gray wolves expanded territory while many species reduced their geographic range, indicating complex species-specific responses to human activity.

The research provides new insights for conservation strategies, suggesting that temporary restrictions on human access to critical habitats could benefit wildlife. The study helps disentangle human presence effects from habitat modification, revealing that human impact alone significantly shapes animal movement patterns.
