The Kruger National Park (KNP), South Africa
KNP covers nearly 2 million hectares of land

Wildlife tourism, grazing land for livestock production, provision of food
(e.g proteins, fruits, honey) and energy resources
Provision of Ecosystem Services

Frequent droughts, bush encroachment, overgrazing, rhino poaching
Threats to Kruger National Park ecosystem

SAR and mapping of woody cover, biomass,
volume
Assess multi-frequency SAR in typically heterogeneous shrub and tree mix Combined L&C&X-band > L-band (ALOS PALSAR) > C-band (RADARSAT-2) > X-band (TerraSAR-X) SAR better predict woody volume > cover = biomass
X-band
R² = 0.32
RMSE = 10.88 t/ha
SEP = 59.82 %
C-band
R² = 0.60
RMSE = 7.81 t/ha
SEP = 43.66 %
R² = 0.78
RMSE = 6.05 t/ha
SEP = 32.90 %
L-band X+C+L-
band R² = 0.83
RMSE = 5.20 t/ha
