the vegetation types and veld condition - Maremani Nature Reserve

The assignment is interpreted as follows:
TERMS OF REFERENCE
Classify, describe and map the vegetation types, assess the veld condition and determine the ecological
capacity of suitable grazer and browser game species for the area.
1. Initial preparation
Obtain all relevant maps (topocadastral, geology, land types), stereo aerial photographs, climatic data
(rainfall and temperature), as well as information on the infrastructure and natural environment of the area
concerned. Stratification of the area into relatively homogeneous units on aerial photographs, by using a
stereoscope, on the basis of physiography and vegetation cover.
1. Vegetation and habitat survey
Survey the stratified units and record all identifiable plant species, as well as habitat features, e.g.
geology, topography, aspect, slope and rock cover. Classify the data by means of the TURBOVEG and
MEGATAB computer programs and describe and map the different plant communities. Identify alien
species and possible encroacher/invasive plant species.
Determine the structure of the plant communities in terms of canopy cover and density for different strata.
Quantitatively survey the grass species composition to assess veld condition to calculate the economic
carrying capacity of each plant community. Determine the aboveground grass biomass was determined.
Identify and map management units based on vegetation types, environmental features, rivers and the
present road network. Compile a checklist of the plant species of the area.
2. Economic carrying capacity for game
Determine the grazing and browsing capacity for the area under long-term average rainfall conditions.
Calculate the stocking rate based on present game numbers. Recommend game numbers and ratios of
grazers and browsers for the area, based on present veld condition and economic capacity.
Identify ecologically sensitive areas and/or problem areas in need of special management, e.g. bush
encroached, eroded and degraded areas.
3. Monitoring and recommodations
Recommend aspects of the vegetation that should be managed and monitored.
