Abstract (en):
The dry enclave of Amaime River is one of the few places that remain as Tropical Dry Forest in the Valle del Cauca department, which is considered one of the most threatened ecosystems in the Neotropics. The site has been heavily transformed and threatened by anthropic means like continued burning for the suitability of land for agriculture and livestock, small short rotation crops among others. The aim of the study was to develop detailed inventories of avifauna, herpetofauna, mammalian fauna, and flora in relict sub-xerophytic forests of the enclave,
therefore revealing the biodiversity of these remnants, their conservation status and potential threats in order to propose recommendations for conservation. Four sampling areas were selected with cover vegetation as thorny scrub vegetation, riparian forests and forest fragments. For registration and data collection mist nets, transects, direct observations and Sherman traps were used, additionally informal interviews with the community were performed. Despite the reduction of vegetation cover in the dry enclave of Amaime River, the forest fragments serve as shelter and feeding site for both transient species and typical dry and very dry forest wildlife.
Abstract (es):
El enclave seco del río Amaime es uno de los pocos lugares con remanentes de bosques seco tropical en el departamento del Valle del Cauca (Colombia), considerado uno de los ecosistemas más amenazados en el Neotrópico. El enclave se halla fuertemente transformado y amenazado por continuas quemas para la adecuación de tierras para actividades agrícolas y ganaderas, pequeí±os cultivos de rotación rápida entre otras amenazas. El objetivo del estudio fue elaborar inventarios detallados de avifauna, herpetofauna, mastofauna y flora en relictos de bosques subxerofítico en el enclave, que permitan conocer la biodiversidad de estos relictos, su estado de conservación y posibles amenazas con el fin de plantear recomendaciones para su conservación. Se seleccionaron cuatro zonas de muestreo con cobertura vegetal como matorrales espinosos, bosques ribereí±os y fragmentos de bosque. Para el registro y toma de datos se usaron redes de niebla, transectos, observaciones directas, trampas tipo
"Sherman" y entrevistas informales con la comunidad. A pesar de la reducción de la cobertura vegetal en el enclave seco del río Amaime, los fragmentos boscosos y matorrales no solo albergan fauna y flora propia de bosques secos y muy secos, sino que también sirven como refugio y sitios de alimentación para especies transitorias.
