# Coyotes Spotted Using Unfinished Wallis Annenberg Wildlife Crossing Remote cameras capture coyotes exploring the massive structure before its official December opening. - **Source:** [Los Angeles Times – California](https://www.latimes.com/california) - **Published:** 2026-11-06 - **Topic:** [science](https://brifing.si/c/science) - **Original article:** - **On Brifing:** https://brifing.si/s/93658723-df3f-4148-a568-c0072fd52e08 ## Early Wildlife Activity A second coyote was recently documented on the Wallis Annenberg Wildlife Crossing, marking a significant milestone for the project. This sighting occurred just eight days after the first coyote was spotted on the structure's slope. These events provide early evidence that local fauna are beginning to investigate the massive overpass before its official opening. ## Crossing Construction Status The Wallis Annenberg Wildlife Crossing, spanning the 101 Freeway, is scheduled to officially open on December 2. While the main overpass features a lush landscape of 6,000 native plants, adjacent sections remain under construction. Continued grading and infrastructure improvements have recently enabled larger mammals to access the structure for the first time. ## Behavioral Observations Biologists noted the coyote spent approximately 20 minutes on the overpass, suggesting the animal felt comfortable despite the proximity to 300,000 daily vehicles. Although the coyote eventually doubled back toward the Simi Hills, the duration of its stay indicates that the naturalistic design successfully minimizes the stress typically caused by freeway noise. ## Monitoring and Data Collection Wildlife branch chief Seth Riley and biologist Jeff Sikich have installed six remote cameras to monitor the crossing. Future plans involve a network of over 50 cameras and thermal video sensors. Scientists also intend to use GPS collars and implanted biologgers to track physiological data like heart rates and fat reserves in animals. ## Ecological Connectivity Goals The primary objective of this crossing is to reconnect wildlife populations isolated by urban development and freeways. For decades, the Santa Monica Mountains have acted as a barrier, trapping species. By providing a safe corridor, the project aims to facilitate movement between the Santa Monica Mountains and the Simi Hills for various species. ## Addressing Genetic Isolation Mountain lions in the region face existential threats due to critically low genetic diversity caused by inbreeding. Researchers have documented physical deformities, such as kinked tails and deformed testicles, resulting from close relatives mating. The crossing is intended to allow fresh bloodlines to enter the area, potentially reversing these dangerous biological trends. ## Species-Specific Usage Patterns While coyotes are described as bold explorers, other species like bobcats may require more vegetative cover to feel secure. The current planting strategy focuses on the main overpass, with additional landscaping planned after the ribbon-cutting ceremony. Scientists remain optimistic that apex predators like mountain lions will utilize the bridge regardless of the cover. ## Scientific Significance This project represents a major opportunity to study the impact of habitat reconnection on isolated wildlife populations. By documenting how animals adapt to the new structure, researchers hope to gain insights into long-term conservation strategies. The crossing serves as a vital lifeline, potentially preventing the local extinction of key mountain lion populations. ## Sources covering this story - https://www.latimes.com/environment/story/2026-11-05/second-coyote-wildlife-crossing-101-freeway-wallis-annenberg — --- _Summary written by Brifing from the original reporting.
