Sponsor one tree at a time


Jennifer Leigh Smith
Founder and President

Jennifer Leigh Smith Louisiana was raised in Southwest Louisiana where she earned her Juris Doctorate degree at Louisiana State University in 1993.  After practicing law for 7 years in Louisiana, Jenny decided to get out of the office and into “hands on” work to get more directly involved in her mission to help offset global warming by planting trees. Jenny learned on her family’s established tree farm that planting trees and good land stewardship was a first rate profitable business for all involved, flora and fauna included.

Already fluent in Spanish, Jenny made her new home in Costa Rica in 1998, to help preserve the remaining stretches of rainforest on the Central to Southern Pacific coast. She set out to create a socially responsible reforestation company in an area where the effects of carbon sequestration to balance global warming could be compounded. 

After meeting her mentor Jack Ewing, then working and studying at the Hacienda Baru National Wildlife Refuge, Jenny cultivated a long-standing active relationship with ASANA, the most established grassroots environmental organization in the area, and instrumental in creating the Path of the Tapir Biological Corridor.  Serving on the Board of Directors for over 4 years, and driving ASANA as President during a period of rampant development in the area, Jenny learned firsthand that the social problems faced by Ticos simply cannot be ignored if lasting conservation work is to succeed in Costa Rica.

Jenny has devoted 10 years to finding and brokering appropriate parcels of land for reforestation projects, planting over 160,000 trees, linking together fragmented pieces of rainforest and creating food corridors for both animals and humans. Jenny has worked with many foreign clients on private reforestation projects.  But realizing it is not enough for foreigners to come and plant trees on their land, Jenny’s integrated work relationship with local Costa Ricans inspired her to create Community Carbon Trees in Costa Rica as one creative solution to the gambit of environmental and social problems in Costa Rica and the world at large. 


Juan Angel Mendiola  
Vice President, Systems Manager,
Work Crew Administration

Juan Angel Mendiola hails from Mar del Plata, Argentina but is now a Costa Rican resident. For the last 6 years, Juan has been instrumental in developing the reforestation capacity of Community Carbon Trees in Costa Rica.  He is responsible for the creation of systems for the safe and efficient transportation of trees, and the planting of large reforestation projects in difficult-to-reach locations.  Some projects require infrastructure work such as road and bridge building or repair, water drainage or supply systems, and Juan designs and builds or organizes whatever is needed.  All projects require fences, another area of his expertise.  Practical on-the-ground solutions are Juan’s specialty and his skill as a troubleshooter is invaluable in keeping everything going smoothly.

As Work Crew Administrator, Juan is responsible for payroll and insurances for the work crews.  He also keeps the crews organized and equipped, healthy and motivated.   He is the main link with Luis Arias Alfaro, on-site work manager, to organize the general work team management for day-to-day project planting and maintenance. 

Luis Arias Alfaro
On-Site Captain of Reforestation Crew

Luis Arias Alfaro has been working with Jennifer and Juan for over 5 years, planting diverse large reforestation projects in the Southern Zone. Luis is Captain of the work crew and is relied upon to transport all workers to work site each morning and stay on site until work ends.  Luis guides the reforestation crew in day-to-day planting or maintenance work, and insures that safety and quality are paramount. He implements developed systems for efficient transport and planting to enable crews to plant the maximum number of trees in the most effective way. Safety, good worker communications and respect are of utmost importance, and Luis serves as the glue for Community Carbon Trees in Costa Rica.

Luis also helps to identify and interview Host farm participants and serves as a liaison between Community Carbon Trees and host farm families.


Alvaro Cerdas 
Manager of Sapling Nursery and
Tree Transport

Alvaro Cerdas is a native of the San Juan de Dios valley and has been working with Community Carbon Trees for over four years managing the tree nursery.  Alvaro is in charge of seed collection from healthy trees of designated species, germination of the seedlings and transfer into rooting bags, and maintenance of the saplings until planting season.  Alvaro helps to organize boxes of trees for transport to the planting site and maintains an accounting of which trees are planted in various zones. Alvaro is passionate about finding new and rare species to attract and feed wildlife, and help preserve the natural biodiversity.   Over the years, Alvaro has developed a seed collection network among many local Ticos, who collect seeds from a wide variety of trees for propagation by Community Carbon Trees.  As a result, the nursery currently grows saplings from over 80 different kinds of trees.

Alvaro also helps to identify and interview Host farm participants and serves as a liaison between Community Carbon Trees and host farm families.



The Work Crew                  
Randy, Luis, Jeffrey, Angelo, Liandro, LuiS, Geiner
The planting crews are made up of young local men ranging in age from 17 on up, living in San Juan de Dios area.  Randy and Liandro have been planting trees with Jenny since she began her reforestation company many years ago. While planting season sometimes sees extra workers added to crew rosters, permanent positions are highly prized as they provide good wages, great benefits with bonuses, and good people with whom to work.
