Abstract
Para conocer el estado actual de las poblaciones de los flamencos Phoenicoparrus jamesi y P. andinus en Sudamérica, se realizó el I Censo Internacional Simultáneo de estas dos especies en Argentina, Bolivia, Chile y Perú entre el 23 al 30 de enero de 1997. El censo de estas dos especies de flamencos se realizó en 97 sitios entre lagunas y salares de altura (2.300 a 4.650 m) y se contó con la participación de 56 personas que efectuaron los conteos. Como resultado de este trabajo coordinado entre los cuatro países, actualmente se conoce mejor sus distribuciones, el tamaño de sus poblaciones, las áreas de nidificación y los sitios de mayor interés para la conservación de ambas especies. Los resultados del censo en Bolivia son de particular importancia puesto que después de 13 años en este país, no se habían realizado censos totales de estas dos especies de flamencos altoandinos. Según los resultados finales del censo en los cuatro países, los ambientes acuáticos de la región del altiplano de Bolivia albergan a la mayor población de P. jamesi, con un aproximado del 65% del total (47.619) y una población de P. andinus del 30% del total (33.927). El presente artículo proporciona también información sobre la situación actual de flamencos altoandinos y una síntesis de los principales problemas, con recomendaciones y sugerencias para la implementación de un Plan de Manejo efectivo para la conservación de estas especies en Bolivia.
In order to evaluate the present status of flamingo populations of Phoenicoparrus jamesi and P. andinus in South America, the First International Simultaneous Census was conducted for these two species in Argentina, Bolivia, Chile and Peru, from January 23-30,1997. The census was conducted in 97 sites, comprising saline flats and high-altitude lakes (2300-4650 m). Fifty six people participated in the counting process. As a result of this coordinated effort between the four countries, we now have a better knowledge about the distribution, population size, nidification sites and localititcs of high conservation interest for both species. The results of the census in Bolivia are particularly important because for 13 years no complete censuses were conducted for the two high andean flamingos. According to final results of the census in the four countries, the aquatic environments of the Altiplano region of Bolivia include the biggest population of P. jamesi, with about 65% of the total number (47.619 individuals). The P. andinus populations in Bolivia represents 30% of the individuals counted (33.927). The paper also presents information and a summary of the most important threats to these populations, with recommendations for the implementation of an effective Management Plan for the conservation of these species in Bolivia.
