État de la populationTexte officiel évaluation IUCNExpert
André noted the taxon to be abundant on trees, at the type locality, in 1888. It is described as locally common, between 3,000 and 3,356 m asl, in the Reserve of Pululahua (Rivadeneira-Roura 2007). The size and dynamics of the population are unknown.

Description complète des menacesTexte détaillé évaluation IUCNExpert
Epiphytes have experienced dramatic population decreases mainly because of habitat loss and extraction activities, which have driven many species close to extinction (Mondragon and Calvo-Irabien 2006). Forest fragmentation also facilitates the extraction of ornamental species (Benzing 2000, Filho and Tabarelli 2006), including many Tillandsia species. Hydrophilic, shade loving Bromeliads appear to be more sensitive to anthropogenic disturbance.
Tillandsia species are relatively difficult to propagate and take several years to flower from seeds. Propagation by offsets, which form after flowering, is only in a limited number. These increase the incentive to collect wild specimens for direct sale. Additionally, the taxon appears to have ethnobotanical use in Ecuador (Escuela de Ciencias Biológicas 2007).
Tropical montane forests are especially sensitive to atmospheric climate change and likely to be the most affected. Hydrophilic taxa, such as T. homostachya, are likely to be more vulnerable to climate change (Winkler et al. 2007).

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
The taxon is known to occur within the Pululahua Geobotanical Reserve (category III), however most of the specimens have been collected from outside the protected areas network. The species does not have a legally protected status, however the taxon is cultivated in several botanical institutions.
