We are local activists dedicated to the preservation and conservation of the fragile biodiversity of Costa Rica. We do this by providing environmental education and empowering local communities, especially women, girls and boys.

What we do

At our organization, we use education as a tool to engage and empower local communities in sustainable practices. Through educating children on the importance of protecting the biodiverse land they inhabit, supporting sustainable tourism for local businesses, and partnering with land owners and stewards on sustainable land management practices, such as riparian vegetation, regenerative agriculture and reforestation, we strive to promote harmony between people and nature.

Our focus is local, but our impact is global.

Our mission

We strive to protect Costa Rica’s natural heritage for future generations, through its sustainable development, by promoting education and community empowerment, the strengthening of protected wildlife areas and the promotion of tourism.

Our Programs

The Corcovado Foundation currently has four main areas of work in the Osa Peninsula:














Importance of the Osa Peninsula

The Osa Peninsula in Costa Rica is one of the most biologically intense places on the planet. It boasts a remarkably high biodiversity with twenty-five to thirty different ecosystems. Endangered plant and animal species, including large predators such as jaguars and pumas, call this region home. Additionally, the peninsula harbors many endemic species of birds and trees. Notably, the harpy eagle, once believed to be extinct since 1989, has been found in Corcovado National Park. Humpback whales rely on the waters that surround Isla del Caño and the Golfo Dulce as critical calf birthing habitat.

Jim Damalas

“Looking back now, I was a Hollywood producer who fortunately escaped the frantic pace of Hollywood back in 1992. I soon became convinced that this tiny democratic oasis, with so many diverse tropical climate zones, and more biodiversity compared to all of North America combined, was the answer to my search for my own salvation.

I began my second career as a part time resident, commuting between cultures while pursuing my dream. That dream was to build a boutique hotel practicing sustainable hospitality, starting with a few rooms in 1993, and ended up taking me back to the very same destination where I first pitched my tent to camp on a beach that was to become the world famous National Park of Manuel Antonio. All that eventually led to creating Greentique Hotels.

It now has been 20 years of sharing our unique boutique brands of Costa Rican hospitality. It has evolved from the 7 hours it took on a 4×4 journey of pot filled dirt roads and flat tires to a super paved highway that now takes us just 2.5 hours to get to the resort at Si Como No from the capital of San Jose. Lots of progress has come to Costa Rica’s infrastructure, and though it’s had its costs on the simple pace I discovered back in the seventies, the country still remains committed to sustainable development.”
