Almost half of the world’s human population lives in coastal areas, and associated coastal development has significantly degraded or destroyed many coastal ecosystems. Burgeoning human populations and rising sea levels only further constrain the availability of habitat that coastal species depend on.
California’s 1,100 mile coast has more than 200 threatened, endangered or rare species living in coastal habitats. There are hundreds of coastal estuaries that provide critical rearing habitat for marine species, and are also important for recreation, water filtration, and carbon sequestration.
Only 10 percent of California’s historic coastal wetlands remain. Without intervention, we are at risk of losing 40 percent of our remaining coastal wetlands to sea level rise over the coming decades. Conservancy scientists are working to reverse these trends.

Since a deadly outbreak of pathogenic E. coli in California spinach in 2006, produce growers have been pressured to implement on-farm practices, such as native vegetation removal, in the name of food…

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…
