Wildlife Crossing Records First Large-Mammal Use as Finish Work Accelerates

Expanded cameras and tracking will test whether the bridge restores genetic exchange for isolated animals.

Overview

  • The coyote, which climbed the southern slope on Oct. 28, became the first large mammal photographed on the near-complete Wallis Annenberg Wildlife Crossing.
  • Crews have been building up soil to join the two overpasses so larger animals can traverse the full span and make complete crossings.
  • Park staff have rapidly installed cameras on the structure and plan a monitoring network of more than 50 still cameras and thermal video to document use.
  • Scientists will add GPS radio collars and biologgers to deer and mountain lions to track movement and measure physiological stress and fitness outcomes.
  • The $114 million crossing is set for a Dec. 2 ribbon-cutting and aims to reconnect wildlife isolated by the 101 Freeway, a decades-long conservation effort to reduce road deaths and restore gene flow for mountain lions.
