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.

Groundwater is a critical water supply around the world and is increasingly under threat from pumping that exceeds natural replenishment. Successful implementation of California's Sustainable Groundwater Management Act (SGMA) depends local agencies working with stakeholders to develop plans and implement projects that reduce groundwater use,…

California has ambitious climate and energy policies that call for the development of significant amounts of new zero-carbon energy by midcentury. The Power of Place study looks at multiple pathways to meet California's clean energy demand in alignment with decarbonization goals while limiting the impacts…

In 2014, California passed the Sustainable Groundwater Management Act (SGMA) which regulates groundwater at scale for the first time, requiring the state’s largest source of stored water to be managed for long-term resilience. SGMA delegates the responsibility of achieving sustainable groundwater management by 2040 to…

Ecosystems can increase carbon storage under alternative management techniques and land use patterns. But the magnitude, timing, and spatial heterogeneity is uncertain. Assessing the potential and cost of land management and conservation activities to reduce emissions or increase carbon sequestration is needed to help the…

Restoring habitat in retired farmland could reduce water demand and provide ecosystem services for farmers and local communities. In some areas of California, as a result of the Sustainable Groundwater Management Act (SGMA), it is likely that large amounts of agricultural land will need to…

The Conservancy has a vested interest in preserving farms in Ventura County because they buffer important river and wetland habitat from nearby urban lands. In western Ventura County, over 70% of groundwater use is agricultural. Due to requirements of the Sustainable Groundwater Management Act (SGMA), this use will…

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…

California’s water supply is becoming increasingly unreliable. During dry times, consumptive use often outstrips supplies. As a result, people and nature suffer. This imbalance of supply and demand will likely grow worse if future demand for agricultural and urban water increases alongside a warming climate.…

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…

Integrating ecological data into long-term energy planning is critical to meet both California’s long term energy and conservation goals. This report assesses the potential trade-offs associated with renewable energy build-out by evaluating the land and water use implications and cost of a range of potential…

In 2011, the west coast groundfish fishery transitioned into a catch share fishery, or Individual Fishing Quota management system. Under this type of management system, the annual total allowable catch is divided into shares, or quota, and allocated to individual fishermen. This report describes a…

River restoration projects have the potential to influence many of the services that rivers provide to people, yet rarely is this studied in a comprehensive manner. This paper reports on a set of coordinated studies that were conducted to evaluate the effects of alternative restoration…
