Encountering bison in an unexpected place, such as Catalina Island, may draw visitors’ attention and boost the sale of related novelties, but this mismatched pairing hasn’t worked out so well for the bison. Studies dating back to the 1970s have repeatedly documented limited forage, poor habitat conditions, and poor nutrition, health, and condition of the…
While bison attacks on Catalina Island are relatively rare, they do happen, and the most severe cases often make the news. While working as a wildlife biologist on the island and assisting in the managment of the bison herd, I documented several bison attacks that made the news and a few that didn’t. Unlike Yellowstone…
In 2014 we fitted five Catalina Island bison with global positioning system (GPS) collars to locate the herds systematically and track their movements on the landscape. This article includes information on the GPS collar specifications and a preliminary assessment of the location data we collected. This post complements an earlier article titled Thiafentanil and Medetomidine…
In 2014 we outfitted five Catalina Island bison cows with Global Positioning System (GPS) collars to support my thesis research through Cal State Fullerton. I coordinated a team of wildlife veterinarians to lead the capture and immobilization process with assistance from several of my Catalina Island Conservancy colleagues. I had originally planned to publish this…
In 2003, researchers scoured historical records to identify the origin of the bison on Catalina and construct a timeline of bison additions to the Island. Despite their best efforts, much of the timeline before 1969 remained incomplete. Due to conflicting information about where the bison came from, how many were initially introduced to the Island,…
