Vanessa Caldarelli


Vanessa Caldarelli was raised in a family of conservationists. In 1991 her parents bought 1,000 of the 2,000 acres of Costa Rican rainforest that Eco Era currently protects. Throughout her upbringing Vanessa was taught about rainforest biodiversity, ecosystems, canopy, and watersheds. She holds a strong knowledge of and affinity to the rainforest, that fuels her motivation and perseverance in land preservation. Vanessa graduated with a B.A. from the University of Oregon in 2014. In 2015 and 2016 she worked at the San Francisco Zen Center in agriculture development until transitioning to Costa Rica to work for her father’s rainforest conservation project, Eco Era. After her father’s passing in 2018, Vanessa became the steward of 1,000 acres of Eco Era lands and other properties in Costa Rica. In 2019, she created the start-up company, Posada Natura LLC, of which she is the current CEO. She began developing travel programs that offer healing and spiritual opportunities in Costa Rica that are woven into rainforest conservation and education. In 2020 she became President of Eco Era and has begun to implement social service programs that support rainforest conservation.

Bob Buckter

Bob Buckter was born in San Francisco October 15, 1946. He attended public schools, including S.F. State, where he graduated in Social Sciences and Business in 1969. Bob spent a portion of his youth traveling around the world, including an around the world trip in 1977. Through these experiences he acquired a deep appreciation for the natural world, and a keen desire to protect it. He founded a painting & contracting business in 1970 in San Francisco, which transitioned to color consulting for a living in 1978 which he still does today.  Bob bought, sold, developed, and traded real estate in San Francisco from 1970-1980, then retired at 31 years old.  In 1994, Bob went to see Gustavo Caldarelli's rainforest property in Costa Rica, which inspired him to begin buying properties there for the next six years. His land comprises 1,000 of the 2,000 acres that Eco Era protects. Bob has worn many hats, but he is first and foremost a protector of the rainforest.
