Vegetation Classification and Mapping Report Ready for Yosemite National Park
With partners at the California Department of Fish and Game and Aerial Information Systems, WERC scientist Peggy Moore has coauthored a final, comprehensive report for the Yosemite National Park Vegetation Classification and Mapping Project. The culmination of a decade of data collection and ground truthing, this National Park Service report includes a listing of vegetation types occurring in the park and vicinity, a key for identifying vegetation types in the field, and a listing of types that were mapped and their descriptions. The map encompasses nearly 1.4 million acres in and around Yosemite, includes the distribution of 107 vegetation types within the park and an additional 23 vegetation types in the vicinity, and includes the vegetation mapping of Devils Postpile National Monument.

NEW PUBLICATION BRIEFS
Differences in Postfire Recovery of CA and AZ Chaparral Plant Diversity
According to research by Jon Keeley, C.J. Fotheringham and Phil Rundel at UCLA, chaparral plant communities recover after fire quite differently in Mediterranean-type climates versus non-Mediterranean-type climates. This pub brief summarizes findings published in the journal Madroño, comparing plant biodiversity in the California chaparral with that in the Arizona chaparral, after 2002 fires in southeastern Arizona and 2003 fires in southern California.

A Cascade of Consequences (Science)
Editors Kristen Mueller and Maria Cruz listed a Kevin Lafferty paper in a recent Editor’s Choice section of Science. The study documented a behavior-altering parasite that induces crickets to head towards streams. Preferring crickets, local trout abandon their normal aquatic insect prey, whose numbers rise and cause a decrease in algae and leaf litter in that food web.

Helen Gibbons showcases photos and highlights from the USGS family science fair in May, including WERC booths on sea otter and salt ponds research.

California Sea Otter Population Continues Tepid Pace of Recovery
Brian Hatfield and Tim Tinker summarized findings for the 2012 population survey of the southern sea otter (Enhydra lutris nereis), a threatened species. The averaged population index for 2012 is 2,792. Although this is a slight uptick overall from recent surveys, the population appears to be experiencing stagnant or negative growth in some stretches of the California coast, and slight growth in other areas. The survey is conducted for the U.S. Fish and Wildlife Service, in collaboration with California Department of Fish and Game, Monterey Bay Aquarium, UC Santa Cruz, and Bureau of Ocean Energy Management.
