Origin and Habitat: Pachycereus weberi is endemic to Mexico, where it occurs in the states of Guerrero, Morelos, Oaxaca and Puebla.
Altitude range. It grows at elevations of 600 to 1,500 metres above sea level.
Habitat and ecology: It occurs in tropical deciduous forest. This species can form forests where it is the dominant species, which are known as "cardonales". In the Tehuacán-Cuicatlán Valley, densities of 150 adult individuals/hectare are reported. Pachycereus weberi is listed as Least Concern due to a wide distribution, and because it is locally abundant and is not declining at nearly the rate sufficient to qualify for listing in a threatened category. However the species habitat is being destroyed in some areas for cattle ranching and small-scale farming.

Common Names include:
SPANISH (Español): Cardón Espinoso, Candelabro, Chico
