Elkhorn Slough Foundation

Join a community that’s making a difference!

Currently, Elkhorn Slough Foundation owns or manages nearly 4,000 acres of land in the Elkhorn Slough watershed. These lands are critical to the long-term health of the entire Elkhorn Slough ecosystem. For a relatively small investment today, we will be able to protect the lands in and around the Central Coast’s premiere estuary for years to come.

Other ways to give:

Making a contribution in someone else’s name is a wonderful way to honor that person. The person or family will receive a letter informing them that a gift as been made to honor them or their loved one.

Memorial Gifts – Provide a way of remembering those that have passed away while honoring them through the lasting legacy of conserving the rare and beautiful Elkhorn Slough.

Tribute Gifts – Provide an excellent manner to honor an individual (or group) with a gift that will support the conservation and restoration of the amazing environment of Elkhorn Slough.

Adopt an oak

In 2015, we planted 150 coast live oak trees on our conserved property to help restore oak woodland habitat.  We want these little oaks grow into sturdy trees so that future generations can admire the ancient oaks of our watershed.  Throughout their lives, these trees will provide habitat for birds and shelter for a variety of wildlife. 

This is your chance to be part of creating an oak woodland.  You can adopt an oak and watch it grow too.  When you “adopt” your tree you will receive a Google Earth link that shows the tree assigned to you.  As the years go by, you can view the progress of your adopted tree with every Google Earth image update. Imagine the changes you might see as the oak sapling becomes a mighty oak and habitat for wildlife.  You’ll even receive your “Virtual Oak Adoption Certificate.”  And you will know your oak is protected on the conserved lands of the Elkhorn Slough Foundation.

You can “adopt” an oak for yourself or a friend.  Since an adopted oak is a living thing, it will grow and change with the passage of time, making it the perfect gift for new baby, birthdays, weddings, and any celebration.

You and your tree – as well as the entire oak grove – are helping to restore the Elkhorn Slough to a native California environment.

Give the gift of Elkhorn Slough to friends and family who share the passion for this diverse and amazing environment.

They are sure to appreciate your generous thought to help them enjoy and preserve the Elkhorn Slough.

It’s hard to imagine a greater legacy than preserved land. Elkhorn Slough Foundation has promised to care for thousands of acres on the Central California Coast. To assure this perpetual protection, our Board of Directors has established a permanent endowment. You can help ensure the future conservation of the Elkhorn Slough as a member of our Legacy Circle by simply including the Elkhorn Slough Foundation in your will or estate plan. Legacy Circle gifts help build ESF future while also supporting our daily operations.  Unless otherwise specified by the donor, we are committed to placing 75% of received bequest contributions into our Legacy Fund to support the future of ESF.  The remaining 25% of the contribution is put to work immediately to help fund our conservation and restoration efforts today.

Through your will or revocable living trust, you can specify that a portion of your assets benefit the Elkhorn Slough Foundation beyond your lifetime, and your estate may be able to take a charitable deduction for the amount of your bequest.  You generous legacy will enable future generations to explore and enjoy the Elkhorn Slough.

Please consult your tax advisor for how donating stock to ESF will best benefit you.
