CA Rock Crab Fishery Management

Sean P. Fitzgerald, Jono R. Wilson , Hunter S. Lenihan

Despite the economic value of California fisheries, many lack information needed to determine if fishing is occurring at a sustainable level. The Southern California Rock Crab fishery in the Santa Barbara Channel is one such data-limited fishery that is currently managed through a state-wide size…

Conserving California's Coastal Habitats: A Legacy and a Future with Sea Level Rise

Walter N. Heady, Brian S. Cohen, Mary G. Gleason, Joshua N. Morris, Sarah G. Newkirk, Kirk R. Klausmeyer, Hilary R. Walecka, Elizabeth Gagneron

Sea level rise presents a new challenge to coastal conservation. The authors quantified and mapped the vulnerability of habitats, imperiled species, and conservation lands to sea level rise throughout the entire California coast, where high biodiversity, high endemism, and 26.5 million people coincide. Combining habitat…

Adaptive comanagement to achieve climate‐ready fisheries

Jono R. Wilson, Serena Lomonico, Darcy Bradley, Leila Sievanen, Tom Dempsey, Michael Bell, Skyli McAfee, Christopher Costello, Cody Szuwalski, Huff McGonigal, Sean Fitzgerald, Mary Gleason

Climate change is amplifying threats to ocean ecosystems and marine fisheries worldwide. In order to respond appropriately in the face of these ocean changes, commercial and recreational fisheries management requires improved information collection, expanded utilization of diverse data sources, and enhanced decision-making. While advances in science and…

Partnerships in Fisheries Management

Wilson J. , McGonigal, H., Dempsey, T., Gleason, M., Rienecke, S.

Fisheries management in California is a complex, resource intensive process that is limited by funding and staff capacity. In this report, Conservancy scientists and colleagues identify ways in which non-governmental organizations and individuals, including fishermen, can engage in aspects of management. The report suggests that…

Aquaculture by Design, Tomales Bay

Serena Lomonico, Robert Jones, Torrey Johnson, Sarah Newkirk, Sarah Lummis, Kirk Klausmeyer, John Finger, Terry Sawyer, Richard James

Aquaculture is becoming an increasingly important global food source. With this growth comes urgent, unanswered questions about the interactions of aquaculture operations—both positive and negative—and ecosystems. This video describes a collaboration between the Conservancy, the University of California, Santa Cruz, and Hog Island Oyster Company aimed at…

Dynamic conservation for migratory species

Mark D. Reynolds, Brian L. Sullivan, Eric Hallstein, Sandra Matsumoto, Steve Kelling, Matthew Merrifield, Daniel Fink, Alison Johnston, Wesley M. Hochachka, Nicholas E. Bruns, Matthew E. Reiter, Sam Veloz, Catherine Hickey, Nathan Elliott, Leslie Martin, John W. Fitzpatrick, Paul Spraycar, Gregory H. Golet, Christopher McColl, Scott A. Morrison

What if instead of buying habitat, conservationists could rent it when and where nature needs it most? The Conservancy is using predictive models of shorebird movements, data from the citizen science program eBird, and NASA satellite wetland habitat data to create a habitat marketplace of…

Strugnell, Mao-Ning Tuanmu, Samantha Twiname, Adriana Verg´es, Cecilia Villanueva, Erik Wapstra, Thomas Wernberg , Gretta T. Pecl

Climate change is driving the largest global redistribution of the planet’s species since the ice age. Species redistributions present challenges for human well-being, environmental management and sustainable development. Species redistribution also poses new questions for the study of ecosystems, conservation science and human societies that…

Big Data and the Deep Blue Sea

The Nature Conservancy, Matt Merrifield

Nearly half of the world depends on seafood for their main source of protein. In the Western and Central Pacific, where 60% of the world’s tuna is caught, illegal, unreported, and unregulated fishing practices are threatening marine ecosystems, global seafood supplies and local livelihoods. This…

Market and design solutions to the short-term economic impacts of marine reserves

Daniel Ovando, Dawn Dougherty, Jono R. Wilson

No-take marine reserves are a management intervention that can provide long-term fishery benefits. But, impacts of reserve implementation can negatively affect fishermen profits in the short term. This study examines how to overcome the losses in profit associated with implementing reserves. The authors found that creative…

Sustainable Management of Abalone Fishery in California

The Nature Conservancy, Jono Wilson

California fisheries, like the red abalone fishery, are facing increasing environmental variation and uncertainty due to climate change, complicating the sustainable management of commercial and recreational fisheries and threatening the resilience of fishing communities. To better manage these resources, better data is needed. In this video,…

Marine and Coastal Impacts of Ocean Desalination in California

Szeptycki, L., E. Hartge, N. Ajami, A. Erickson, W. N. Heady, L. LaFeir, B. Meister, L. Verdone, J.R. Koseff

The drought in California rekindled interest in ocean desalination as a new and reliable water supply option; yet desalination is expensive, energy intensive, potentially emits greenhouse gases, and has adverse impacts on coastal and marine ecosystems. This report is a synthesis of an Uncommon…
