In 2022, the longest predator‑exclusion fence in the Pacific was completed on the Hawaiian island of Kauai. The 11,200‑foot‑long fence encircles 168 acres of prime ground‑nesting seabird habitat and was designed to keep feral cats and pigs out of the area.
According to Good News Network, the fence protects a range of endangered seabird species that previously faced constant predation from these invasive animals. Four years after the fence’s installation, the nesting birds are reported to be following their natural behaviors, indicating the barrier is effectively reducing predation risk.
Such fences are a critical conservation tool in the Pacific, where invasive mammals threaten native wildlife. This project demonstrates how large‑scale, targeted habitat protection can help safeguard vulnerable bird populations.
