Conservation status The assessment included 22 collections representing 22 localities and yielded an EOO of 4,275 km 2, an AOO of 64 km 2, and nine subpopulations representing eight locations, of which three occur within two protected areas (Torotorofotsy and Zahamena). With ongoing habitat degradation and loss resulting from shifting agriculture, forest exploitation and industrial mining, N. mangorensis is assigned a preliminary status of “ Vulnerable ” [VU B 1 ab (ii, iii, iv, v) + 2 ab (ii, iii, iv, v)], although a reduction in EOO is not expected in the near future.
