Indirect evidence on the presence of the Andean bear (Tremarctos ornatus Cuvier, 1825) in northwestern Argentina

Abstract

Preuves indirectes de la présence de l'ours andin (Tremarctos ornatus Cuvier, 1825) dans le nord-ouest de l'Argentine. La présence d'ours andins (Tremarctos ornatus) en Argentine a été contestée en raison de l'absence de preuves confirmantes. De nombreux experts en ours andins doutent actuellement de leur présence dans ce pays. Cependant, la forêt Tucuman-Bolivienne ou Yungas est un écosystème typique où cette espèce peut être trouvée, en particulier dans la zone étudiée, où l'habitat semble être de haute qualité pour les ours. Entre 2001 et 2006, 23 cas de preuves de la présence d'ours andins dans les provinces de Salta et de Jujuy ont été enregistrés. Des empreintes de pieds, des restes de nourriture et des écailles ont été trouvés. En outre, les indigènes, les agriculteurs et les chasseurs interrogés pour recueillir de nouvelles données sur cette espèce. La conclusion est que la forêt Yungas du nord-ouest de l'Argentine doit être considérée comme une zone à forte probabilité de maintenir une population résidente d'ours andins. Bien qu'il s'agisse probablement d'une population petite et peut-être isolée, la présence permanente d'ours andins dans le nord-ouest de l'Argentine pourrait ne plus être mise en doute.

Evidencia indirecta sobre la presencia del oso andino (Tremarctos ornatus Cuvier, 1825) en el noroeste de Argentina. La presencia de osos andinos (Tremarctos ornatus) en Argentina ha sido disputada debido a la ausencia de evidencia confirmatoria. Muchos expertos en osos andinos actualmente dudan de su presencia en este país. Sin embargo, el Bosque Tucumán-Boliviano o Yungas es un ecosistema típico donde se puede encontrar esta especie, particularmente en el área estudiada, en la que el hábitat parece ser de alta calidad para los osos. Entre 2001 y 2006, se registraron 23 casos de evidencia sobre la presencia de osos andinos en las provincias de Salta y Jujuy. Se encontraron huellas, restos de alimentos y escorias. Además, nativos, agricultores y cazadores donde se entrevistaron para recopilar nuevos datos de esta especie. La conclusión es que el Bosque de Yungas del noroeste de Argentina debe considerarse un área con alta probabilidad de mantener una población residente de osos andinos. Aunque esta es probablemente una población pequeña y quizás aislada, la presencia permanente de osos andinos en el noroeste de Argentina podría no ser dudada por más tiempo.

Indirect evidence on the presence of the Andean bear (Tremarctos ornatus Cuvier, 1825) in northwestern Argentina.The presence of Andean bears (Tremarctos ornatus) in Argentina has been disputed due to the absence of confirming evidence.Many Andean bear experts currently doubt on their presence in this country.Nevertheless, the Tucuman-Bolivian Forest or Yungas is a typical ecosystem where this species can be found, particularly in the studied area, in which the habitat appears to be of high quality for bears.Between 2001 and 2006, 23 cases of evidence on the presence of Andean bears in the provinces of Salta and Jujuy were recorded.Footprints, food remains and scats were found.In addition, natives, farmers, and hunters where interviewed to collect new data of this species.The conclusion is that the Yungas Forest of northwestern Argentina must be considered an area with high probability of maintaining a resident population of Andean bears.Although this is probably a small and perhaps isolated population, the permanent presence of Andean bears in northwestern Argentina might not longer be doubted.

أدلة غير مباشرة على وجود دب الأنديز (Tremarctos ornatus Cuvier، 1825) في شمال غرب الأرجنتين. تم التنازع على وجود الدببة الأنديزية (Tremarctos ornatus) في الأرجنتين بسبب عدم وجود أدلة مؤكدة. يشك العديد من خبراء الدببة الأنديز حاليًا في وجودهم في هذا البلد. ومع ذلك، فإن غابة توكومان- بوليفيان أو يونغاس هي نظام بيئي نموذجي حيث يمكن العثور على هذا النوع، لا سيما في المنطقة المدروسة، حيث يبدو أن الموئل ذو جودة عالية للدببة. بين عامي 2001 و 2006، تم تسجيل 23 حالة من الأدلة على وجود الدببة الأنديزية في مقاطعتي سالتا وجوجوي. تم تسجيل بصمات القدم وبقايا الطعام والسكات. بالإضافة إلى ذلك، قد لا يكون هناك شك في وجود السكان الأصليين والمزارعين والصيادين حيث تمت مقابلتهم لجمع بيانات جديدة من هذا النوع. الاستنتاج هو أن غابة يونغاس في شمال غرب الأرجنتين يجب اعتبارها منطقة ذات احتمالية عالية للحفاظ على عدد سكان الأنديز. على الرغم من أن هذا ربما يكون هذا العدد صغيرًا وربما معزولًا، فإن الوجود الدائم للأنديز في شمال غرب الأرجنتين قد لا يكون موضع شك بعد الآن.
