Marantaceae and Cyperaceae. Cyanastrum cordifolium (Cyanastraceae) another
common feature of Atlantic-type forest is also common encountered on the forest
floor. The highly seasonal nature of the area also means that variations in water levels
in many rivers and streams expose extensive rocky areas. A common and persistent
coloniser of these oft-flooded rocks is Biophytum petersianum (Oxalidaceae) a small
rhizomatous herb widespread in the Korup forest but not commonly encountered
elsewhere.
As the altitude increases, especially where the dramatic relief and rocky outcrops
preclude the ability of forest to fully develop and persist, many open areas are
commonly encountered in this forest type, most notably on hill sides and ridge tops.
Whilst not strictly “highland”, at altitudes often less than 700m, these vegetation
formations, often characterised by dense, monospecific stands of Acanthaceae and
Costaceae as well as members of the Balsaminaceae also being common, are more
commonly associated with higher altitude vegetation.
3.3.3.5 Forest exploitation
There is little or no exploitation for timber in Takamanda. The harvest and sale of
some high-value non-timber forest products comprises a large proportion of the
household income (Groves and Maisels, 1999; Ifeka, pers. comm.). In particular, bush
mango (Irvingia gabonensis and I. wombolu) is of significant importance and is
widely traded as is njansang (Ricinodendron heudelottii) and njabe oil (Baillonella
toxisperma). Rattan is not harvested at levels beyond immediate household
requirements.
3.4 METHODS
3.4.1 Sampling
A series of 1ha plots were established in each of the survey sites. The number of plots
that were established at each site was dictated by both biological and logistical
factors. A stratified random sampling design was followed to ensure that the plots
were representative of the forest type within each reserve area and provide a
reasonably homogenous sample within that variation. In total nine, 1ha plots were
established: two in Takamanda, three in Campo and four in Mokoko. Although the
