Nestled across northern Mexico and the southwestern United States, the Sky Island bioregion encompasses 55 mountain ranges and adjoining valleys, grasslands, and deserts. These ‘islands’ rise above the surrounding ‘sea’ of lowlands, forming vital pathways for migratory species between diverse ecosystems.

These landscapes bridge the gap between the Sierra Madre and the Rocky Mountains, making them pivotal for maintaining biodiversity and connectivity. Conservation International recognizes this region as a global hotspot due to its unique climate, elevation, and proximity to montane areas.

In this context, the Gila Wilderness emerges as a stronghold of diversity within New Mexico. Its striking topography and climate, similar to the Sky Islands offer refuge for nearly 80 species of concern. It links Mexico and the Sky Islands as a migratory route, ensuring species’ movement amid changing conditions. This connectivity makes both the Gila Headwaters and the Sky Islands critically important for securing a lasting and resilient diversity of species and ecosystems in this region.
