Climate Connectivity Analysis: An Innovation Approach to Identifying Critical Habitat in California

Alex Leumer, Carrie Schloss, Cara Lacey

Plants and animals lack the ability to change their environment. As their current habitat becomes unsuitable due to climate change, they may search out new, more suitable habitat to adapt to changing conditions. With limited resources for protecting additional lands, the conservation community must protect wildlife today and ensure that those investments will lead to a resilient, biodiverse future. To help guide conservation decisions and investments optimized for both current and changing climate conditions, the Conservancy produced an analysis of the “state of habitat connectivity” for California. Read more about the analysis and its application in this California Adaptation Forum blog post and this Science in Action summary

Jedlicka, Kelly Gravuer, Sara M. Kross, Deborah A. Bossio, Andrés Muñoz-Sáez, Deirdre G. LaHue, Kelly Garbach, Lawrence D. Ford, Mark Felice, Mark D. Reynolds, Devii R. Rao, Kathleen Boomer, Gretchen LeBuhn, Lynn V. Dicks

Agricultural management practices impacts not only on crops and livestock, but also soil health, water quality, wildlife, and ecosystem services. There is abundant, but disconnected, scientific evidence for the impacts of different practice. But this evidence is often not used in decision making by farmers or…

Although environmental conservation, human health, and sustainable development challenges are interconnected, approaches to these challenges and the evidence used remain disconnected. Creating integrated solutions across these sectors will require better alignment of the methods used to assess the problems and quantifying success. In this review,…

Collaborative research reveals cryptic declines within the multispecies California rock crab fishery

Sean P. Fitzgerald , Hunter S. Lenihan, Jono R. Wilson, Carolynn S. Culver, Matthew Potoski

This paper highlights the benefits of collaborative fisheries research in the management of wild capture fisheries. The authors teamed up with commercial fishermen in the southern California rock crab fishery and sampled over 45,000 crabs over a two-year period. Using statistical techniques, they compared these data to a study…

Growers say cannabis legalization excludes small growers, supports illicit markets, undermines local economies

Hekia Bodwitch, Jennifer Carah, Kent M. Daane, Christy Getz, Theodore E. Grantham, Gordon M. Hickey, Houston Wilson

Cannabis has been an industry in the shadows for many decades and little studied. In partnership with U.C. Berkeley and U.C. Cooperative Extension, Conservancy staff developed the first cannabis growers survey on cultivation practices in California, and also asked questions about grower’s experiences with the…
