Gray whales have one of the longest migrations of any mammal, traveling each year from calving lagoons along Mexico’s Baja Peninsula up to feeding grounds in Alaska’s Beaufort Sea. Similarly impressive migrations along the Pacific Coast are made by other whale species, as well as elephant seals, sea lions, sharks, tuna, and the millions of birds that traverse the Pacific Flyway.
The promise of large open spaces drew the emerging photographer to North America, where he discovered that even large areas of protected wilderness like Yellowstone National Park aren’t safe from fragmentation. For example, the artificial boundaries of large parks don’t necessarily take the migrations and dispersal of wildlife into account. Schulz argues that parks can become prisons rather than preserves, especially as climate change causes ecological boundaries to shift. Schulz is a proponent of wildlife corridors, which he believes can correct the fragmentation caused by human-designated wilderness areas by acting as land or water bridges that allow wildlife to move between parks and ecosystems.
