OTS established the La Selva Research Station in 1968. Before it was under OTS leadership, La Selva was a farm dedicated to sustainable forest research owned by Dr. Leslie Holdridge.
La Selva’s influence on tropical ecology is immeasurable and of great cultural significance, having served as a key training and research site for numerous professional scientists. La Selva Research Station pioneered private forest conservation in Costa Rica, as it was the first of what is now a large network of private forest reserves in the country.
The species richness of La Selva is outstanding, with more than 2,077 species of plants; 125 species of mammals (72 of them bats); 470 species of birds; 48 amphibian species; 87 species of reptiles; 45 species of freshwater fish; and tens of thousands of insects, arachnids, and other arthropods.
La Selva Research Station offers 1,600 hectares of well-preserved old-growth and recovering wet lowland tropical forest that abuts the Braulio Carrillo National Park. The 4 to 6 km wide forested corridor that connects La Selva at 35 m above sea level to the Barva Volcano at 2,906 m is one of the best-preserved elevational gradients in the tropics.
La Selva sits within a complex biological, socioeconomic, and political landscape that has been significantly transformed over the last 40 years by a continuously expanding agricultural frontier, burgeoning human population, and accompanying major infrastructure. Protected areas, such as La Selva, provide a rich opportunity for studying how natural ecosystems respond to a broader landscape matrix of human uses.
La Selva has some of the longest running ecological data sets in the tropics, spanning up to 40+ years. Long-term research of terrestrial and aquatic ecosystems has generated data on nutrient cycling, plant and animal demography (e.g. birds, trees, frogs, etc.), community interactions, and their responses to a changing climate.
Key Research Themes
- Forest dynamics and nutrient cycling
- Forest succession
- Global change and human-nature interactions
- Aquatic ecosystems
La Selva’s juxtaposition of protected ecosystems and well-developed facilities is unique in the world’s wet tropics.
- Friendly and helpful staff, including a science team, is available to answer questions.
- La Selva can fully accommodate 180 overnight visitors.
- We offer a dining hall, laundry service, store, wireless internet, library, all-access trail, and on-station security.
- Our extensive network of paved and dirt trails (61 km) provides convenient access to a wide range of terrestrial and aquatic habitats.
- The station has several buildings that house laboratories and offices. There are two air-conditioned laboratories with basic equipment and several specialty areas including analytical, microbiology, and ambient labs.
- The herbarium houses more than 10,000 specimens of dried, pressed plants including fruits and seeds, as well as wet specimens, and several other reference collections.
- The Academic Center includes a conference room, four classrooms, four laboratories, and temporary offices for course faculty.
San Juan-La Selva Biological Corridor
La Selva is approximately a 2-hour drive from San José.
Directions: Take the “Zurqui” Route 32 Highway through the Braulio Carrillo National Park towards Guapiles. After approximately 45 minutes, you will drive over the Sucio River; continue for 7 Km to a major intersection at a restaurant called Rancho Robertos. Turn left, and continue towards the town of Puerto Viejo in Sarapiquí. Follow the highway (Route 4) approximately 30 km to the entrance of La Selva (on your left). The entrance is 3 km before the intersection of Puerto Viejo.
Buses leave from the “Caribeños” terminal in San José throughout the day. Make sure to take the bus to Puerto Viejo in Sarapiquí and not the bus to Puerto Viejo in (Talamanca) Limón!
