État de la populationExpert

The population occurs in patches, form 10–500 individuals. Hower, it is estimated that the whole population hardly reaches 10,000 mature individuals. In the last decades, this population size has been reduced due to the frequent fires in the region and a continuing decline in the mature individuals of at least 10% is estimated to occur in the future. The plant growth rate seems very slow, so sexual maturation must be at least after they are 20 years old (E. Martínez Salas and Hernández-Sandoval pers. comm. 2019).

Description complète des menacesExpert
The main threat to this species is the degradation of its habitat. More specifically, the frequent wildfires and fires usually occur in the whole range which cause direct mortality (E. Martínez Salas pers. comm. 2019).

Mesures de conservation recommandéesExpert
Nolina robusta occurs in the Biosphere Reserve "Sierra Gorda" (Querétaro). This species is not known from any ex situ collections (BGCI 2019). Habitat and natural process restoration would be beneficial with support of efficient measures that can control and mitigate frequent fires in the area, in order to reduce direct mortality. In addition, monitoring of the habitat is recommended.
