Habitat and Ecology [top]

Habitat and Ecology:This species grows in generally well drained soils and under arid conditions. Dry oak forests at low elevations. Occasionally in hilly grasslands. Does seem to persist somewhat in highly disturbed areas.
Generation Length (years):30

Threats [top]

Major Threat(s): Habitat destruction is fortunately not as severe as in areas with more fertile soils. Most of the habitat is used for grazing cattle and this causes little damage to the cycads.
