KEY TO ABBREVIATIONS FOR TABLE 13
Ecological type: (based on Iversen, 1991b)
• F - Forest dependent species: Species previously recorded as restricted to primary or closed canopy forest only, e.g. wet
evergreen forest, dry evergreen forest and/or riverine forest;
• f - Forest dwelling but not forest dependent: Species previously recorded in primary or closed canopy forest as defined
above and/or in forest edge, clearings, secondary forest, deciduous forest and woodland, and
• O - Non-forest species: These are species that do not occur in primary or secondary forest or forest edge (e.g. species that
have been recorded in bushland, heathland, thicket, secondary scrub, grassland, rocky outcrops, swamps, wastelands and
cultivation.
Habitat: (based on Hamilton, 1989)
• L - Lowland: Species occurring at altitudes less than 850m above sea level;
• S - Submontane: Species occurring at altitudes greater than 850m above sea level.
• M – Montane Species occurring at altitudes greater than 1,250m above sea level.
If species occur in more than one habitat range, this has been recorded (e.g. L&S – this species has been recorded at altitudess
between 0 and 850m above sea level).
Endemic status: (based on Iversen, 1991b):
• E - Endemic: Occurring only in the Usambara mountains, EU - Range limited to the East Usambara Mountains, WU -
Range limited to the West Usambara Mountains;
• N - Near endemic: Species with limited ranges in the Eastern Arc mountains and/or the East African lowland forests;
• W - Widespread distribution.
4.3.1.12 Opportunistic plant collection and observation
A total of 34 species of dicotyledons were opportunistically recorded within Mgambo FR. These
represented 22 families. An additional one near endemic and one forest dependent species were
recorded during opportunistic collection.
Eight species from the opportunistic checklist (Table 14) are new species records for the East
Usambara Biodiveristy Database. These species are summarised in Appendix 4.
