Albuquerque lies within the center of the Albuquerque Basin ecoregion, centered on the Rio Grande with its Bosque gallery forest, flanked easterly by the Sandia-Manzano Mountains and westerly by the West Mesa. Located in central New Mexico, the city also has noticeable influences from the adjacent Colorado Plateau semi-desert, New Mexico Mountains forested with juniper and pine, and Southwest plateaus and plains steppe ecoregions, depending on where one is located.
