Verification of the model for indicators of biodiversity change in a CDM forestry project (Procuenca) in the watershed of the Chinchiná River
Status: In progress
In the watershed of the Chinchiná river (Caldas department), the project Procuenca was established with the objective of consolidating a sustainable forestry initiative that ensures both healthy hydrographic function and biodiversity conservation, while generating an alternative form of production and employment for the city of Manizales and the surrounding region.
Procuenca was the first forestry project to be registered with the United Nations Clean Development Mechanisms (CDM) program in Colombia, generating benefits through the mitigation of climate change by guaranteeing the capture of carbon dioxide. Additional environmental benefits include improving water quality and the protection of the regions flora and fauna by creating biological corridors that connect forest fragments in the upper reaches of the watershed, through the restoration of highly degraded areas.
En 2006 Procuenca developed a series of biodiversity indicators and a descriptive model that categorizes the integrity of the fauna in the different landscape units within the watershed. Currently, both the indicators and the model are being verified now that the CDM project is in its fifth year.
As part of this verification, the SELVA research team will design and implement an analytical model to evaluate the indicators through a comparison of biodiversity in the different stages of the forestry project.
Key findings & achievements
As a result of observations, sound recordings and captures with mist-nets, 139 species of birds have been recorded. These include two species threatened with extinction (IUCN 2010), including the Golden-plumed Parakeet (Leptosittaca branickii) and the Rusty-faced Parrot (Hapalopsittaca amazonina), the latter record corresponding to a new location for the species. Further, two endemic species, the Chestnut Wood-Quail (Odontophorus hyperythrus) and the Stiles’s Tapaculo (Scytalopus stilesi), were recorded and four species of boreal migrants.
In the upper reaches of the watershed, we recorded ten species of frogs, one species of salamander and one toad species from the genus Rhamphophryne. The latter is not only considered a new species for the watershed but remarkably a new species for science. One other species represented an addition to the inventoryof species recorded during initial surveys six years ago. One preliminary result from the comparison of amphibians in different types of land use in the watershed is that both young and old pine plantations provide more favorable conditions for amphibians than extensive areas of cattle pasture.
During bat surveys in the upper reaches of the watershed a total of 85 individuals were captured representing eleven species. All the species recorded were from the family Phyllostomidae and were distributed within three sub-famalies, stenodermatinae, carollinae (fruit-eating bats) and glossophaginae (nectivorous and insectivorous bats). The most abundant genera include the frugivorous Carollia and Sturnira that typcially use pioneering plants are a food resource. Other mammals recorded included one species of primate, Alouatta seniculus, one species of carnivora from the Procyonidae family, Potus flavus, and three species of rodents from two families, Coendou sp. (Erethizontidae), Sciurus granatensis and Microsciurus sp. (Sciuridae).
