Website Links Salmon Stream Vital Signs of Point Reyes, Golden Gate and Redwood Parks
In cooperation with the National Park Service, WERC scientist Mary Ann Madej has compiled NPS Vital Signs data for the Klamath (KLMN) and San Francisco Bay Area (SFAN) networks of national park units onto a one-stop resource. The graphs visualize long-term records, such as stream discharge at 28 different stream gages, as well as weather, stream temperature and salmonid counts for some streams. The PRISM Climate Group at Oregon State University contributed information on local climate parameters. The website is part of a project with USGS Western Geographic Science Center scientist Alicia Torregrosa and USGS Forest and Rangeland Ecosystem Science Center scientist Andrea Woodward to create a systems dynamics model that simulates the freshwater portion of the coho salmon (Oncorhynchus kisutch) lifecycle.

IN THE NEWS
Adak Caribou: Invasive Species or Meals on the Hoof? (Anchorage Press)
Reporter Mary Lochner mentions WERC scientist Mark Ricca’s Biological Invasions study on the nonnative caribou populations on Adak Island in Alaska.
Greater Sandhill Cranes Glide into California’s Central Valley Early This Year (Sacramento Bee)
Reporter Edward Ortiz’s story features WERC data and interviews Mike Casazza research collaborator Gary Ivey of the International Crane Foundation.
Endangered Mountain Yellow-Legged Frogs Might Get a Hoppy Ending (Los Angeles Times)
Reporter Louis Sahagun accompanied WERC scientists Adam Backlin and Liz Gallegos into the San Gabriel Mountains and provides an update on the recovery of the federally listed Rana muscosa.
WATCH ON YOUTUBE
Visit the USGS YouTube Channel to watch the “Catching Sea Otters in the Wild” and “Dry Suits” videos, featuring scientists from the USGS Alaska Science Center and WERC. Footage was shot by ASC scientist Vanessa von Biela during the 2011 Alaska expedition of the Pacific Nearshore Project. WERC produced the films, edited by CSU Humboldt student and former USGS Calif. Water Science Center intern Martha Aimé Cardona.
WERC IN PROGRESS
Linking Populations with Watersheds
Researchers collaborating on the Pacific Nearshore Project are trying to integrate data from coastral terrestrial systems with nearshore marine systems in order to model the land-sea interactions that drive nearshore marine productivity and health — including those of finfish and sea otters — and compare trends from California north to Alaska. WERC scientists Roberto Lugo and Bill Perry have been testing ways to extrapolate existing population data to enhance the model, and arrived at an interpolation method which extrapolates U.S. Census block data onto roadways, then clipped by subwatershed boundaries (roughly HUC14). Researchers and modelers who wish to comment or offer ideas on the method can reach Lugo at firstname.lastname@example.org.
