Big Game Most big game species underwent population fluctuations since European settlement, with often critically low numbers in late 1800’s early 1900’s, with some recovery since then Many occur now only in fragments of their historic ranges, Some have local populations high enough to cause environmental damage For all species, human-wildlife interactions are increasingly key to population health and survival Increasing need to think in terms of populations rather than species 10 Big Game species in AZ Elk Issues: Overabundance and Ecological Impacts Predator Interactions (Yellowstone) Vehicular collisions White-tailed deer Issues: Overabundance/Ecological Effects Managing urban pops Mule deer Issues: Declining populations nationwide Black tailed deer Javelina (collared peccary) Issues: Human-wildlife interactions Decline outside US Pronghorn Issues: Grazing vs predation in declining pops Habitat fragmentation (fences, highways, development) Sonoran pronghorn recovery Bighorn Desert bighorn Issues: Maintaining isolated small pops Corridors? Dall sheep Rocky Mountain Bighorn Bison Issues: Brucellosis in Yellowstone herd Native to AZ and fate of House Rock herd? Puma Issues: Human-Puma interactions Estimating pop size Recovery of Florida Panther Black bear Issues: Bear-human interactions Methods of take Male display Wild turkey Issues: Expansion and maintenance of populations Caribou Moose Mountain goat Abert (tassel-eared) squirrel Red squirrel Az grey squirrel Cottontail rabbit Scaled quail Gambel’s quail Bobwhite quail Mearn’s (harlequin) quail Introduced game birds Ring-necked pheasant Chukar Native grouse and ptarmigan Ruffed grouse – deciduous forests of N and NE Blue grouse – High elevation Ptarmigan - High elevation Rockies Alaska, Canada Lesser Prairie Chicken Plains states Sharp-tailed grouse – High plains, Dakotas, Nebraska, etc Sage grouse - sage brush areas of western states Mourning dove White-winged dove Collared Dove INVASIVE!
