Agua Salud (Panama)
The Native Species Plantation within the overall Agua Salud Project was established in 2008. The plantation is designed to test hypotheses related to the growth and development of native species in monocultures and mixtures as well as ecosystem function and services. Native timber species were chosen as target species as the overall theme of the project is related to understanding ecosystem services and as carbon credits alone will not cover the establishment and management costs of plantations in Panama.
There is an application trial linked to this experiment.
Design
The Agua Salud Native Species Plantation is approximately 75 hectares and is divided into two blocks of roughly equivalent size that are 3 kilometres apart. Each block contains 21 different treatments (mixtures), each treatment present in 6 or more replicate plots. The plots are randomly distributed within a block. The species were selected based on physiological and morphological traits, and the target species are long-lived pioneer species.
