We identify issues and uncertainties that pose obstacles to conservation and then—in collaboration with internal and external colleagues—develop science products that help overcome those obstacles.

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…

Policies that incentivize forest conservation by monetizing forest carbon ultimately depend on the accuracy of carbon stock estimates. Often, these estimates are based on field inventory sampling. In…

In response to the decline of wetland habitats for migrating and wintering water birds in California, the Conservancy developed a program called BirdReturns that creates “pop-up”…

In this study, the authors developed a suite of species distribution models (SDMs) for the endangered giant kangaroo rat using the machine-learning method Maxent. They compared these models with three…
