The Big Arroyo herd was reestablished in 2014 with the translocation of 14 Sierra bighorn from the Mt. Baxter and Wheeler Ridge herds. Access to this herd is difficult, which gives us limited opportunity to monitor the bighorn on foot. Difficulties are compiled by the large amount of distance between different groups of bighorn in this herd unit.

Two years after translocations, our best count of this herd was a total of 22 animals. In 2020, we counted a total of 28 animals in the herd.
