Watch Oregon Field Guide online: Episode 11 Brown Pelicans, Freeriding, Oak Savannah

The brown pelican has rebounded so successfully, the government has removed it from the endangered species list. Today, the largest pelican roost site in the Northwest sits in Oregon. But when thousands of pelicans lingered too long, winter storms caused severe injuries. Volunteers with the Wildlife Center of the North Coast rushed to save them, nurse them and months later, release them to the wild. Painful, thrilling, crazy -- these are just some of the terms freeriders themselves use to describe their sport. Freeriding is a new twist on a style of mountain biking that originated in Canada where wooden ramps and bridges and logs were laid so bikers could avoid muddy forest trails. Join a group of these daring thrill-seekers in the Oregon forests as they negotiate trails over four-inch logs, high platforms, and bone-rattling jumps. Several endangered Oregon species, including the Kincaid's lupine, rely on oak savannah, a type of habitat that once covered a million acres in the Willamette Valley. Now only pockets of the distinctive landscape of huge oaks and open grassland remains.
