The goal in traveling to the Sierra El Tigre - one of the most extensive of the sky islands - was to complete a basic bio-geographical assessment of the area, listing species of flora and fauna present in the Sierra El Tigre and especially “Fracción Número III Sierra El Tigre” property of Francisco Tarazón, located within the limits of the Ajos-Bavispe Reserve. We also sought to determine the extent of past and present human disturbance and impact as well as the extent of wilderness character in the range.
