Elk are frequently seen in and around Grand Canyon Village on the South Rim of Grand Canyon National Park. In this Ranger Minute, Park Ranger Haley Bercot shares some interesting facts about this majestic animal. What should one do if they sight an Elk? How close should one get? Can elk be dangerous? Many visitors see large wild animals that seem tame and therefore approach far closer than they should. For safety's sake stay at least 50 feet away from the elk! Never approach wild animals. Photograph all wildlife from the safety of your vehicle. Use telephoto lenses and observe quietly. It is dangerous, and illegal, to feed wild animals in a national park. Violators will be fined. Wildlife can become dependent upon handouts and lose their ability to hunt and forage. Such animals lose their fear of humans. They can become aggressive and bite, kick, or gore. Many are struck by cars while searching for handouts. Help us keep wildlife wild. Never feed or approach wildlife.

How is the Ponderosa pine able to grow throughout the American West? Well, the secret to the tree's success is how well it has adapted to fire. Join Park Ranger Haley Bercot as she describes the unique ways in which the Ponderosa pine is able to protect itself from fire. But, what about people, what about those of us who live in these fire prone ecosystems? What about our homes? Our belongings? Our lives? We’re not naturally adapted to fire, but I think we can make a start by following the example of the Ponderosa Pine. Ponderosas protect themselves from fire with their armor of thick bark. We can do the same by using fire resistant building materials in our homes, and surrounding our homes with a defensible space.
