État de la populationTexte officiel évaluation IUCNExpert
Most of its subpopulations are distributed in the state of Jalisco and a few individuals are found in Michoacán near the type locality. It is estimated the population has a total number of mature individuals of less than 10,000. It is likely the current population trend is declining due to the habitat threats, mainly because of the expansion of the agriculture frontier (Hernández-Sandoval pers. comm. 2019).

Description complète des menacesTexte détaillé évaluation IUCNExpert
The main threat for Nolina rodriguezii is ecosystem alteration. More specifically, the practice of extensive agriculture is the main productive activity across the taxon range. This practice has reduced the habitat quality and EOO. Additionally, urban expansion is another threat (E. Martínez Salas pers. comm. 2019).

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
Nolina rodriguezii occurs in the Natural Resources Protection Area "C.A.D.N.R. 043". This species is not known from any ex situ collections (BGCI 2019). Control of urban expansion in the range is needed to avoid an intensive change of land use. It would be beneficial to recommend sustainable associated production and livelihood alternatives. In addition, it is suggested to monitor the habitat trend.
