Impatiens hildebrandtii

Conservation status
.—
Impatiens firmula
has at present only been observed at Angavokely Forest Station (
S18°55’37.9”
E47°44’22.1’’
) at
1776 m
. The species may be rare and endangered, as many montane forests in the central highlands of
Madagascar
have been heavily logged but it is considered by the authors as Data Deficiency (DD). The locality observed in 2008 at the summit of a hill was already destroyed in 2014 due to antenna constructions.

Impatiens hildebrandtii
is at least present in large populations in the Reserve Speciale Analamazotra near Andasibe- Perinet National Park. The new
Impatiens otto-eleonorae
is only known from the
type
locality at Masoala Peninsula. Both are local endemics occurring in protected areas and could be classified as Endangered (EN).
