Animals' Reactions to Be Measured with Technology at Massive Wildlife Crossing
At the world's largest wildlife crossing, opening in December, scientists will use new technology to study the physiological reactions of animals.
The Wallis Annenberg Wildlife Crossing, scheduled to open in California in December, is preparing not only to monitor animal crossings but also to measure their physiological responses.
Construction Process and Scope of the Crossing
The cost of the Wallis Annenberg Wildlife Crossing project, located in Agoura Hills, California, has been set at $114 million. After decades of planning and fundraising, construction began in 2022, and the foundational structure has now been completed.
The 210-foot-long and 174-foot-wide concrete bridge over the freeway was finished more than a year ago, and crews later completed the concrete deck of the second bridge over Agoura Road.
Restoration of Biodiversity
The main purpose of this bridge is to reconnect endangered species such as mountain lions and bears that have been separated by the busy highway.
The project aims to revitalize regional biodiversity and serve as a model for similar projects to be undertaken in the future.
Biologging Technology and Physiological Data
In addition to traditional tracking collars, scientists will use specialized biologging tags to understand how animals interact with the bridge.
Functioning like a Fitbit for animals, these collars will collect physiological indicators such as heart rate and body temperature, alongside GPS data.
Opening Date and Impact of Weather Conditions
Originally targeted to open in 2025 after breaking ground on Earth Day 2022, construction was delayed by record rainfall in 2023 and 2024.
The ribbon-cutting ceremony is scheduled for December 2, though it is noted that potential delays could occur if the El Nino weather pattern brings storms.
