At each of our research stations, we strive to maintain species lists for the fauna and flora. Please refer to the station of interest to download the lists in an excel file, which includes information about the author and the year the list was updated.
Species lists for La Selva include mammals, birds, reptiles, amphibians, fishes, and vascular plants. Click here to access information on vertebrates. See the Digital Flora for information about vascular plants. Please contact Orlando Vargas if you have any questions about the species lists from La Selva.
Species lists for Las Cruces include mammals, birds, reptiles, amphibians, dragonflies, trees, orchid genera, and lichens. A collection of bird calls from Melissa’s Forest Restoration Project at Las Cruces can be found below, including metadata and details for each recording. Please contact Rodolfo Quiros if you have any questions about the species lists from Las Cruces.

Species lists for Palo Verde include mammals, birds, reptiles, amphibians, and aquatic plants. Please contact Enrique Castro if you have any questions about the species lists from Palo Verde.
OTS Plant Database (PV, LC, LS)
Dried plant specimens collected from the three research stations in Costa Rica are stored onsite at the herbarium of the respective research station. Researchers have built these collections as they have deposited duplicates of their specimens in the stations’ herbaria. OTS staff have also expanded these collections for research reference and study. These specimens are available for study and loan.
Digitized versions of these specimens are stored in the OTS plant database in a tab called “Herbarium Specimens.” In addition to the digitized herbaria, the database includes additional plant collections like seeds, fruits, or pollen. The data types for the station of interest will appear in additional tabs. For both Las Cruces and Palo Verde, images of live plants for a subset of species are available in the database. For La Selva, find the live images in the La Selva Digital Flora. Please click here to access the OTS Plant Database. For more information about the OTS Plant Database, please contact Oscar Madrigal.

Leslie Holdridge Arboretum
The 3.5-hectare Holdridge Arboretum is located at La Selva Research Station. Leslie R. Holdridge, the original owner of the property, created the arboretum in 1968. Initially, it was a small cacao grove with an exceptionally rich overstory of native shade trees. To facilitate research in the arboretum, staff later removed the cacao. In 1970, Gary Hartshorn continued to plant seedlings of many native tree species. OTS continues to plant, tag, and measure trees. OTS maintains the arboretum by regular mowing and pruning to facilitate safe access. Courses, natural history visitors, students, and researchers use the arboretum for a wide range of observational studies, manipulations, dendrological practices, and taxonomy classes.
Wilson Botanical Garden
The Wilson Botanical Garden (WBG) is a 10-hectare research and educational facility located at the Las Cruces Research Station. The WBG contains a collection of nearly 3,000 species with a particular emphasis on bromeliads, heliconias, tree ferns, palms (approximately 500 species), and bamboos from all over the tropics. Courses on tropical botany, plant systematics, horticulture, and agroecology visit the WBG. Researchers, tourists, or other educational visitors are welcome as well. To access specimen information, please visit the Wilson Botanical Garden Collection. The page opens to a map of the garden. Access the ascensions by pressing the “Collections” button.
At each of the OTS stations in Costa Rica, we have collected long-term meteorological and hydrological data. Please contact each station for a description of the instrumentation and data collected at each station. For La Selva contact Bernal Matarrita, for Las Cruces contact Rodolfo Quirós, for Palo Verde contact Juan Serrano.
Click here to enter the database. Choose the site and data range to display the data. Once the data displays, clicking on the column header will sort the data by that variable, as well as indicate the units of measurement. Please contact Oscar Madrigal with any questions about the database.
La Selva Christmas Bird Count
The Christmas Bird Count (CBC) at La Selva began in 1985 as an official circle of the Audubon’s CBC. Every year since that time, the data has been complied and submitted to Audubon. The data is also available on a website created by La Selva staff. On this website, in Spanish, you will find information on the routes in the La Selva and Braulio Carrillo Circle, as well as information about each species. If you have any questions about the La Selva CBC, please contact Orlando Vargas or Enrique Castro.
