4.2 AIMS
The aim of this study was to survey both mature and regenerating trees and shrubs within
Kazimzumbwi FR in order that they may be assessed in terms of species richness, species
diversity, forest dependence, endemic status and conservation concern. In order to produce a
comprehensive woody-plant checklist, opportunistic collections were also made.
4.3 METHODS
The flora of Kazimzumbwi FR was surveyed using a combination of systematic vegetation plots,
regeneration sub-plots and opportunistic botanical collections. For detailed research aims,
objectives and methods see Methodology Report (SEE 1997).
Scale:
1.2 km

4.3.1 VEGETATION PLOTS
Quantitative vegetation analysis was carried out using a 50m x 20m plot as a sampling unit. Plots
were arranged on a 0.6km x 1.2km grid system (0.6km north-south, 1.2km east-west), with plots
located in the south-east corner of each grid (Figure 6). Using a systematic grid would allow all
habitats and vegetation types to be sampled. The grid system was superimposed on a map of the
forest reserve and plot locations (grid references) calculated.
Plots were located in the field by following a compass bearing and using a hand-held GPS unit
when nearby. Plots were aligned north-south 20m and east-west 50m using a compass and were
temporarily delimited using ropes. The dbh (diameter at breast hieght; 1.3m) of all live trees or
shrubs of >10cm was measured. All stems of mutli-stemmed individuals were measured
