Sonoma State University biology professor Karina Nielsen has been awarded a three-year grant to study an edible seaweed collected extensively in Mendocino County whose aggressive collecting may lead to local extinction. The grant for $129,000 was awarded by the National Organization of Atmospheric and Oceanic's California Sea Grant program.
Because the demand for seaweed has risen significantly in recent years, and because little is known about their basic natural history, some biologists worry that the sea palm may be vulnerable to overexploitation.
The Sea Palm is an intertidal, cold-water kelp that resembles a small palm tree and whose edible fronds are likened to low-fat, mineral rich noodles. Sea palms are just one of a handful of edible seaweeds harvested in California and sold dried at health food stores, Asian markets, and more recently through the Internet which Nielsen feels has appeared to accelerate its sales. "Sea Palm Strudel" can be found on the menu of a local Mendocino restaurant.
Nielsen's work, in collaboration with University of California, Santa Barbara biologist Carol Blanchette, will provide marine regulators with the information they need to ensure sustainable commercial use of the seaweed. The project will examine the biology of the California sea palm (Postelsia palmaeformis) and study the effects of different collecting practices on sea palm reproduction, growth and abundance. Nielsen will also explore the extent to which the kelp's annual cycles and growth patterns vary with latitude.
In collaboration with the California Department of Fish and Game, the project will analyze seaweed collection data and use new biological information to evaluate whether current regulations are ensuring a sustainable industry. "Karina Nielsen's work will build on department research from the early 1990's and be a valuable asset in helping us protect this unique resource," says Peter Kalvass, a DFG marine biologist.
Results of this project will also be communicated to undergraduates enrolled in a new course at Sonoma State University, "Ocean Sicence Literacy for School and Society" and through UC Santa Barbara's Marine Science Institute via its Outreach Center for Teaching Ocean Science and the Research Experience and Education Facility.
