Conservation status Noronhia insularis is currently known from five collections representing five localities. The estimates provided an EOO of 1,535 km 2, an AOO of 20 km 2, and four subpopulations representing four locations, two of which occur within protected areas (Réserves forestières de Tchaourembo et de Bénara). The subpopulations in Grande Comore and those that are outside of protected areas in Mayotte are heavily impacted by habitat degradation and habitat loss resulting from land conversion, thereby reducing the number of mature individuals. Therefore, N. insularis is assigned a preliminary status of “ Endangered ” [EN B 1 ab (ii, iii, v) + 2 ab (ii, iii, v)].
