Indigenous people had several different types of management activities to ensure future corm production at gathering sites: 
breaking off cormlets from the harvested parent corms and replanting them
sparing whole plants
harvesting the corms after plants have gone to seed and dumping the seeds in the hole
burning areas
irrigation
Periodic digging and thinning of the corms or separating the cormlets, and replanting them may have enhanced plant numbers and densities.
 Digging corms acts as a form of tillage, which will increase the size of the gathering tract, aerate the soil, lower weed competition, and prepare the seedbed to increase seed germination rates.
Dichelostemma capitatum populations require periodic disturbance to maintain and increase their populations; therefore, indigenous harvesting regimes may help maintain populations.
 Populations that become overcrowded and show reduced vigor can be divided and separated.
