The Marine Mammal Center is a nonprofit veterinary hospital, research and educational center dedicated to the rescue and rehabilitation of ill and injured marine mammals, primarily elephant seals, harbor seals, and California sea lions. Its research team studies the causes of illness in these animals, and by doing so, learns about conditions affecting the health of marine mammal populations and the oceans – discovering conditions that can affect humans as well. In addition, the Center’s education programs teach thousands of students and the visiting public each year about marine mammals and the urgent need for environmental stewardship of earth’s marine environments.

The Ocean Foundation (TOF) is a unique community foundation with a mission to support, strengthen, and promote those organizations dedicated to reversing the trend of destruction of ocean environments around the world. Our slogan is "Tell Us What You Want To Do For The Ocean, We Will Take Care Of The Rest." We work with a community of donors who care about the coasts and oceans. In this manner, we grow the financial resources available to support marine conservation in order to promote healthy ocean ecosystems and benefit the human communities that depend on them. We operate using a well-established business model (the community foundation) to serve donors and partners interested in marine conservation. TOF does this by increasing the capacity of conservation organizations, hosting projects and funds, and supporting those working to improve the health of ocean species globally. To do this, we raise millions of dollars each year to support marine conservation. These funds come from individuals, corporate donors, private foundations, and governments. We meet our mission through five lines of business: Fiscal Sponsorship Fund services, Field of Interest grantmaking Funds, green Resort Partnerships, Committee and Donor Advised Funds, and Consulting services.

Save the Bay™, and keep it saved, as defined by reaching a 70 on CBF's Health Index. The Chesapeake Bay Foundation's (CBF) mission, simply stated, is to Save the Bay and keep it saved. We define a Saved Bay as having a score of 70 (out of 100) on CBF's State of the Bay health index. Thanks largely to a dramatic reduction in the amount of pollution entering the system, at 70, the Chesapeake Bay and its tributary rivers will be highly productive and in good health as measured by established water-quality standards. The result will be clear water, free of impacts from toxic contaminants, and healthy oxygen levels, able to support living resources in all parts of the Bay.

As California State Parks’ statutory non-profit partner, we have a clear mission – to help strengthen parks and inspire all people to experience these extraordinary places. We are an independent 501c3 organization that supports California State Parks. What does it mean to be "the statutory partner?" That just means we were created by an act of the Legislature to address a big need identified by Governor Brown's blue-ribbon panel on the future of parks. The Parks Forward Commission concluded in 2016 that State Parks need a non-profit partner, or what they termed "a support entity." So, we were founded in 2019 to full this important need. Why would a state agency like The Department of Parks and Recreation, need a non-profit partner? Well, the short answer is: the same reason National Parks need the National Parks Foundation. Closer to home, the same reason every public school needs a PTA or parent association. That is, to fund and to implement innovative and critical programs that are not covered by the public funds. Put another way, to be the nimble partner of State Parks, what some have called "the R&D arm" of State Parks. If we want parks to be strong for the next generations, we need to be thinking now about equitable access (making sure that people from all backgrounds can get to and feel welcome at parks), and about climate resilience. Those are two of the key areas of work for Parks California. Parks California is helping make parks more welcoming, inclusive, and climate resilient. We want to be sure parks are strong and available for many generations to come. Thanks for helping!
