Plant a Tree in Costa Rica – Península de Osa

We are planting trees to restore ecosystems in Peninsula de Osa, which houses 2.5% of the Earth’s biodiversity!

By planting trees on Peninsula de Osa, we aim to protect and restore threatened animal and tree species from the IUCN Red List, such as the endangered Central American Squirrel Monkey, also known as Mono Titi, which is threatened mainly by deforestation activities, and pet trade at the local and international level. As part of our tree planting efforts, local inhabitants receive training and incentives to protect the ecosystem and engage in sustainable harvesting practices.

What´s included?

Reporting and Transparency

We take great care to ensure the success of our land plots. From the moment they’re planted, each plot is photographed and geolocated, and every plant is closely monitored to ensure optimal growth. Once a year, we provide a report on the planted areas, allowing you to track the project’s progress and its impact on the region.

Local education and development

Besides restoring the environment, the project benefits the local economy through seasonal employment. Trees are planted by landowners and residents, while local assistants maintain the nursery and monitor the trees. In addition, environmental education events are executed in schools to improve environmental awareness.

Ecological infrastructure

We allocate a portion of our funds towards enhancing the ecological infrastructure and data collection of the region. This includes constructing bridges to facilitate safe dispersion of fauna, improving the project’s nursery and equipment, collecting important data on the animals and expanding our reach to new areas. By ensuring the safety of endemic animal species, we can greatly improve the overall health and resilience of the ecosystem.

How do we select our trees?

Our tree planting service prioritizes the environment by selecting the right trees for you. We choose from a range of options, including fruit trees, red-listed trees, fast-growing trees for shade, and palm trees. Our expert team considers biodiversity recovery and sustainable planting practices in our tree selection and planting. With us, you can make a positive impact on the environment without having to choose the trees yourself.

The selection of native species to be restored is based on two criteria:

Their value to the fauna

The threat category of the tree species themselves

Our local partner

Saimiri Foundation of Costa Rica, was established on April 18, 2010, with the objective of rescuing, preserving and protecting Costa Rica’s natural resources. It is dedicated to protecting non-human primates habitats in the Osa Peninsula, from environmental and anthropogenic threats.

Where is the Planting Site located?

Our planting sites are located near the community of Guadalupe de La Palma, Osa Peninsula, just 4 km from the Corcovado National Park and the Ngobe Alto Laguna Indigenous Reserve. We select the planting sites according to their environmental potential of connecting forest areas and the availability of these degraded lands from local farmers that will contribute to their restoration.
