In Tribute

alvaro ugalde

Álvaro Ugalde

The late Álvaro Ugalde, founder of the National Park Service in Costa Rica, was a pioneer in the field of land conservation and an inspiration to all who knew him. As a biologist and world-renowned conservationist, Álvaro’s work helped transform Costa Rica. His vision and passion for the Osa Peninsula were contagious and he continued to fight for the Osa and Corcovado National Park until his last day.

His tenure on the board of Osa Conservation made us a better organization and we are forever grateful for his leadership and his contribution to us and to the world.

Osa Conservation, with the support of the blue moon fund, has created two funds to honor the memory of Alvaro and to continue his life’s work. The Álvaro Ugalde Scholarship Fund will provide small grants to young people studying and working in the field of conservation. The Campaign for Corcovado will support efforts to strengthen Corcovado National Park and remove illegal gold miners threatening the integrity of the park.
