Introduction: The environment > WebBefore 1905, the deer on the Kaibab Plateau in Arizona were estimated to number about 4000 on almost 300,000 hectares of range. Because these corridors traverse vast landscapes (i.e., up to 150 miles), they are increasingly threatened by roads, fencing, subdivisions and other development. Is it possible to share that with me? Were these methods successful? The first step to protect the deer was to ban all hunting. In ecology textbooks prior to the 1970s, Aldo Leopold's classic story of predator control, overpopulation of deer, and habitat degradation on the Kaibab Plateau during Water availability throughout seasonal ranges may be the limiting factor for this population. <>/ExtGState<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>>
