5.4.1.3 Mammal observations
A total of 22 species from 14 families were observed directly and indirectly but not retained for
taxonomic purposes. This included species detected from the presence of tracks, paths, diggings
and feeding sites, but not those detected through the dung survey. All mammal observations are
summarised in Table 23. As many observations were made by indirect means, positive
identification was not always possible to a species level. An ‘identification confidence’ column
clarifies the reliability of each sighting. Identification is ranked as follows: Certain, Near Certain,
Probable, Possible.
Of particular interest was the sighting of the Rhynchocyon petersi (Zanj elephant shrew) which is
forest-dependent, near endemic and endangered (IUCN 2000). (Table 23). Observations were
made of up to six different groups of forest dependent Colobus angolensis palliatus (Black and
white colobus monkey) in patches of lowland and riverine forest throughout the reserve. These
primates, although considered widespread, seem to be limited to rapidly decreasing areas of
lowland forest and must be at risk from local extinction due to limitations to disperse and
interbreed. Also of interest was the sighting of the vulnerable (IUCN 2000) Paraxerus palliatus
(Red bellied coastal squirrel).
Five nocturnal species were seen and/or heard at trapsite 3, an area of good lowland and riverine
forest. These were the Dendrohyrax validus (Eastern tree hyrax), which is near endemic and
vulnerable (IUCN 2000); Galagoides zanzibaricus (Zanzibar galago), a forest-dependent species;
