État de la populationTexte officiel évaluation IUCNExpert
Based on herbarium material and sight records, Eriospermum adpressifolium falls into three subpopulations across a narrow area between Sumbawanga and Lake Rukwa, on the eastern slopes of the mountain range.
The biggest subpopulation, where the species has been recorded multiple times, is within 10 km of Sumbawanga, the capital of Rukwa region. The meadows near Ponda (currently a small village of ±400 inhabitants) in particular are at risk of land use change (being turned into maize fields). The locality at Malonje (about 13 km SSE of Ponda) is thought to be safer because of geological conditions unfit for agricultural exploitation. It is likely that additional suitable habitat exists in the region.

Mbizi Forest Reserve is a protected area - a Forest Reserve - encompasses scattered bits of forest with grassland in between; the grassland is burnt regularly and some parts are in poor condition, but overall the area is well-protected (Q. Luke pers. comm. 2022). As this species is probably adapted to fires it will be OK within the Protected Area; but outside the Reserve conversion of grassland to agriculture is a real and existing threat.
