yilíkʷlxkn (Bighorn Sheep) Diseases

March 29th, 2023

yilíkʷlxkn in the southern Okanagan region have been experiencing a steady population decline. This decline is theorized to be due in part to infection by pneumonia or Mycoplasma ovipneumoniae (M. ovi), psoroptes (Psoroptes cuniculi) mites and Bluetongue contributing to overall poor yilíkʷlxkn health. The widespread reduction of available and suitable ranges, and increased human pressure have also been identified as compounding factors to their decline.
