Impact of communal land use and conservation on woody vegetation structure in the Lowveld savannas of South Africa

Author: Wessels, Konrad J ; Mathieu, Renaud SA ; Erasmus, BFN ; Asner, GP ; Smit, IPJ ; Van Aardt, JAN ; Main, Russell S ; Fisher, J ; Marais, W ; Kennedy-Bowdoin, T ; Knapp, DE ; Emerson, R ; Jacobson, J Date: Jan 2011 Millions of people rely on savannas for ecosystem services, such as the provision of grazing and fuel wood, so it is important to determine the extent to which utilization affects woody vegetation resources. Using airborne LiDAR from the ... Read more
Impact of communal land use and conservation on woody vegetation structure in the Lowveld savannas of South Africa – Lidar results

Author: Wessels, Konrad J ; Mathieu, Renaud SA ; Erasmus, BFN ; Asner, GP ; Smit, IPJ ; Van Aardt, JAN ; Main, Russell S ; Fisher, J Date: Apr 2011 People in the rural, communal areas of South Africa rely on live fuel wood for more than 90% of their energy requirements. Using airborne lidar from the Carnegie Airborne Observatory (CAO) the authors compared tree canopy cover and height ... Read more
Retrieval of savanna vegetation canopy height from ICESat-GLAS spaceborne LiDAR with terrain correction

Author: Khalefa, E ; Smit, IPJ ; Nickless, A ; Archibald, S ; Comber, A ; Balzter, H Date: Nov 2013 Light detection and ranging (LiDAR) remote sensing enables accurate estimation and monitoring of vegetation structural properties. Airborne and spaceborne LiDAR is known to provide reliable information on terrain elevation and forest canopy ... Read more
Toward structural assessment of semi-arid African savannahs and woodlands: The potential of multitemporal polarimetric RADARSAT-2 fine beam images

Author: Mathieu, Renaud SA ; Naidoo, Laven ; Cho, Moses A ; Leblon, B ; Main, Russell S ; Wessels, Konrad J ; Asner, GP ; Buckley, J ; Van Aardt, J ; Erasmus, BFN ; Smit, IPJ Date: Nov 2013 Woody vegetation structure affects wildlife habitat selection and species diversity for a wide range of taxa, and at a variety of scales. Indicators of woody structure can indicate the spatio-temporal variability of biodiversity, species ... Read more
Unsustainable fuelwood extraction from South African savannas

Author: Wessels, Konrad J ; Colgan, MS ; Erasmus, BFN ; Asner, GP ; Twine, WC ; Mathieu, Renaud SA ; Van Aardt, JAN ; Fisher, JT ; Smit, IPJ Date: Jan 2013 Wood and charcoal supply the majority of sub-Saharan Africa’s rural energy needs. The long-term supply of fuelwood is in jeopardy given high consumption rates. Using airborne light detection and ranging (LiDAR), we mapped and investigated ... Read more
