Our Impact
After achieving the milestone of planting one million SeaTrees on Earth Day 2021, SeaTrees achieved our next major goal of planting two million SeaTrees across our ten projects. We would like to thank all of our donors and partners who helped make this happen. Our next goal is to support 100 SeaTrees projects by the end of this decade (2030).
2 Million SeaTrees breaks down as follows:
- 1.6 million+ mangrove trees planted at our project sites in Mida Creek, Kenya, Biak Island, Indonesia, and Laguna San Ignacio, Mexico.
- 297,000 sq-ft of kelp restoration at our project sites in Palos Verdes, CA and Tankers Reef, Monterey, CA, USA.
- 9,000 coral fragments restored in Nusa Penida, Bali, Indonesia.
- 684,000+ tons of CO2 sequestered at our project sites in Southern Cardamom, Cambodia and Paramos Y Bosques, Colombia.
- 35,000 sq-ft of watershed restored at our project sites in Maui, Hawaii, Southern Cardamom, Cambodia and Paramos Y Bosques, Colombia.
SeaTrees Supports Sustainable Development
By restoring, replanting and protecting coastal ecosystems around the world through our core conservation partners, SeaTrees supports both the people and the ecological systems they live in.
SeaTrees supports the 17 United Nations / Sustainable Development Goals (SDGs), which are designed to transform our world for good by 2030. (learn more about the UN SDGs)
Collectively, these projects reduce climate change impacts, increase biodiversity on land and in the sea, protect endangered species on land and ocean, create sustainable jobs, alleviate poverty and hunger, support education and gender equality, and more.
Each SeaTrees project is evaluated annually on its impact, according to all of the SDG metrics that apply. Please see the SDG reports for each SeaTrees project below.
SDG Reports for SeaTrees Projects

Palos Verdes
Kelp forest restoration brings back a biodiversity hotspot with over 700 species, and sequesters CO2.

Mida Creek
Mangrove tree planting provides 300 jobs and restores critical habitat for turtles, fish, and migratory birds.

Bali, Indonesia
Coral reef restoration employs local villagers and brings a reef back to life.

Southern Cardamom
Protection of this Ridge to Reef watershed sequesters CO2 and creates 1,000+ jobs for people living inside the project.

Tankers Reef
Kelp forest restoration creates a citizen science program for local communities to restore their local kelp forests.
