What is a Sky Island?

Sky Islands are isolated mountain ranges separated from other mountains by a vast distance and surrounded by lowlands of a dramatically different environment. This results in habitat “islands” such as a high-elevation forest surrounded by desert or grassland. In southern Arizona, part of New Mexico, and northern Sonora, six ecosystems blend to comprise the Sky Island region, supporting a wealth of biodiversity and many species found here and nowhere else.

¿Qué es una Isla del Cielo?

Las Islas del Cielo son sierras aisladas, separadas de otras sierras por una gran distancia y por las tierras bajas circundantes de un entorno dramáticamente diferente. Esto da como resultado “islas” de hábitat, como un bosque de gran altura rodeado de desierto o pradera. En el sur de Arizona, parte de Nuevo México y el norte de Sonora, seis ecosistemas se combinan para formar la región de las Islas del Cielo, sustentando una riqueza de biodiversidad y muchas especies que se encuentran aquí y en ningún otro lugar.
