The Cathedral Range herd was reestablished in the spring of 2015 with the translocation of 13 Sierra bighorn from the Mt. Langley, Mt. Baxter, and Wheeler Ridge herds. Five additional rams were augmented to the herd in the fall of 2016 to increase breeding opportunities. Most of the Cathedral ewes wintered on the Parson’s Plateau in 2016 and 2017. With limited opportunity to breed, as well as the heavy 2017 winter, population size in the Cathedral Range is currently unknown. When this area becomes more accessible the SNBSRP crew will be spending time there to evaluate the population.
