Fire suppression measures are intensified in undeveloped areas near population centers. The natural period between fires in these areas may be altered. Fire suppression activities may also affect the vegetation. High fire frequencies prevent young plants from reaching reproductive maturity and will result in population declines or extirpation once the underground seed bank has been depleted. Nolina interrata flowers profusely after fires.
Plants also reproduce vegetatively from underground stems.
Occurrences that are entirely female require pollen from disjunct male plants to fertilize the flowers and produce viable seeds. Plants in disjunct populations may not flower simultaneously, because flowering is, in part, dependent upon site-specific fire history. Appropriately timed controlled burns may be necessary to maintain population vigor. The threats to this species from changes in natural fire frequencies will be reduced due to the development and implementation of management plans. Because Nolina interrata is known from small populations with relatively few individuals, it is vulnerable to extinction due to random events, such as hot, slow-burning fires.
