Buffelgrass invasion decreased Mammillaria grahamii density in an invaded site. M. grahamii showed association with Parkinsonia microphylla and Mimosa laxiflora. For germination, Small seeds of M. grahamii require light, temperature of 25 °C and high water availability. Seeds of M. grahamii do not germinate at temperatures above 100 °C. Invasion decrease nurse plant cover affecting a population of M. grahamii.
