Of the 14 mammal, bird, reptile and amphibian species which are dependant on primary forest,
only the following were recorded frequently during this survey, Colobus angolensis palliatus
(Angola Pied Colobus), Galagoides zanzibaricus (Zanzibar galago) and Bufo brauni (Dead leaf
toad).
Of the 24 (17%) forest dependant butterfly species, only three species were caught frequently
during the survey. These were Charaxes cithaeron nairobicus, Euphaedra neophron littoralis and
Euptera kinugnana.
5.5.2.8 High risk species
With the assumption that species observed rarely may have a low abundance, species of
conservation concern in Mgambo can be determined. Cryptic species, such as chameleons have
not been included in the following list. The species that were observed infrequently and are both
forest dependent and near-endemic are as follows, Rhynchocyon petersi (Zanj elephant shrew),
Mertensophryne micranotis (Dwarf toad), Leptopelis barbouri (Tree frog), Athroleptides
martiensseni (Usambara montane torrent frog), Scolecomorphus vittatus (Caecilian). Butterfly
species include: Teriominia subpunctata, Acraea cf. matuapa, Charaxes pythodoris nesaea,
Euxanthe tiberius, Hypolimnas usambara and Papilio hornimani.
Specific research would be essential before any further comments were to be made on the
conservation status of specific taxa.
