The Shiras moose is not recognized in Canada, B.C. actually has 3 species of moose although they are not recognized by B&C, in the far north are the Yukon/Alaska, central has the Canada moose and the south border fringe has Shiras. However for the books they only recognize the Canada moose in B.C. As far as California bighorns are concerned they have proven genetically that they are nothing more than a lighter color phase of the Rocky Mtn Bighorn. They are NOT desert sheep, and as such do not deserve a separate recording in the book. Some bioligists will tell you that the color phase known as the Komodi bear is a separate species but it has been proven that they are nothing more than a white color phase of the ordinary black bear. All caribou in B.C. are classed as forest/boreal/mountain caribou, correct or not. I know nothing of the 2 or 3 species of blacktail which may or may not inhabit B.C. Hell there are biologists that would have us believe there are 17 different species of whitetail and 12 or so different species of black bears in NA. Boone and Crockett do not agree and rate their ranges accordingly. There will always be cross overs of arbitrary lines but the big picture is what is considered. The line has to be drawn somewhere....................
