It’s a problem that’s been coming for quite some time, and one that really comes as no surprise. The large landscape national parks that are home to many species of wildlife have been turning into biological islands as development hems them in. You can look back to 1993 when the Yellowstone to Yukon Initiative launched to begin to see the discussion around opening up these parks through migratory corridors. That initiative, which continues today, envisioned a corridor stretching from Yellowstone National Park to Canada’s Yukon Territory to serve wildlife by protecting core wildlife habitat.  There have been other somewhat similar initiatives. There’s the Wildlands Network, which since 1991 has been, as that organization puts it, striving to reconnect, restore, and re-wild North America. There have been efforts in Congress to pass legislation that would provide funding for such corridors. The Pew Charitable Trust this past October released a report on the need for creating migratory corridors and the challenges standing in their way.  Today we’re going to zoom in on some national parks, their wildlife, and the need to establish habitat connectivity between those parks to prevent animals from being stranded on biological islands. Joining us is Dr. William Newmark, a research curator and conservation biologist in the Natural History Museum of Utah.
