Water for Nature: What we can do today to help California’s rivers, streams and wetlands
The Nature Conservancy identified a set of strategies that will have the greatest impact on environmental flows, and to provide a resource for conservation organizations, resource agencies, and other stakeholders in California that will help create the conditions that allow salmon and other freshwater species to thrive well into the future. We evaluated existing strategies available in California to enhance environmental flows for nature, both for in-stream flows and for wetlands. For a select set of priority strategies, we also mapped the geographic potential for implementation, by identifying where the enabling conditions are right for a given strategy, and where the freshwater conservation benefits are highest.

California’s Freshwater Conservation Blueprint
The transformation of California into one of the most productive agricultural and urban landscapes in the world and a growing population have put unprecedented pressure on freshwater habitats, reducing them to a small fraction of their historic extent. Across the state, freshwater-dependent ecosystems have been degraded, resulting in reduced ecological functions and dramatic declines of freshwater species. The Nature Conservancy identified key freshwater species and areas of high conservation value based on where these species occur. The Nature Conservancy and partners are developing a statewide conservation plan for preserving California’s rich freshwater diversity. Download report
The Nature Conservancy analyzed current Chinook, coho salmon, and steelhead trout population and habitat data across California to identify a portfolio of places we call the SalmonScape. View SalmonScape report.
SalmonScape identifies areas in California with the greatest potential for habitat restoration and protection, and where wild salmon also have the best chance of survival. Focusing resources in these priority watersheds will help maximize return on restoration and habitat protection investments. View SalmonScape map.
Marijuana: A Significant Environmental Challenge
Marijuana cultivation can have significant negative collateral effects on the environment that are often unknown or overlooked. TNC convened researchers to spotlight those impacts in a 2015 paper in the journal BioScience: High Time for Conservation: Adding the Environment to the Debate on Marijuana Liberalization. We are collaborating with a broad group of environmental interests to address those impacts by making the case for tightened regulations, beefed up enforcement of environmental laws, and restoration of damaged watersheds.
