| Descripción: | Cusuco National Park, a cloud forest park situated in the Merendon Mountains region of Honduras, is home to considerable biodiversity with a very high degree of endemism. Like many other cloud forest parks in Central America, it was declared a protected area not because of its biodiversity, but mainly because of its function in protecting river water quality in the headwaters draining the park. Illegal and authorised forest clearance for agricultural activity such as coffee production and pasture for animals and diffuse inputs from settlements are expected to affect aquatic macroinvertebrate communities and the water quality of the rivers in the park. There is however very limited water quality monitoring, mainly because biological indices such as those in use in Europe and the United States among others have not been developed in Honduras. A research project based on macroinvertebrates was initiated in 2009 to develop a water quality index for the area. Sampling was undertaken between June and August 2009 and set out to sample minimally disturbed upper catchments of reference rivers. This paper evaluates the performance of several indices. A version of the ASPT based on the BMWP calibrated for Costa Rica (BMWP(CR)) performed best. KEY WORDSBiomonitoring, Honduras, macroinvertebrates, neotropics, upland stream, water quality |
