Analysing surface energy balance closure and partitioning over a semi-arid savanna FLUXNET site in Skukuza, Kruger National Park, South Africa

Author: Majozi, Nobuhle P ; Mannaerts, CM ; Ramoelo, Abel ; Mathieu, Renaud SA ; Nickless, A ; Verhoef, W Date: Jul 2017 Flux towers provide essential terrestrial climate, water, and radiation budget information needed for environmental monitoring and evaluation of climate change impacts on ecosystems and society in general. They are also intended for calibration ... Read more
Bulk feeder or selective grazer: African buffalo space use patterns based on fine-scale remotely sensed data on forage quality and quantity

Author: Kaszta, Z ; Marino, J ; Ramoelo, Abel ; Wolff, E Date: Mar 2016 The distribution and behaviour of African large grazers are regulated primarily from the bottom up, with some species showing clear preferences for certain vegetation types. While the African buffalo (Syncerus caffer) is sometimes considered ... Read more
Characterizing sub-pixel landsat ETM plus fire severity on experimental fires in the Kruger National Park, South Africa

Author: Landmann, T Date: Jul 2003 Burn severity was quantitatively mapped using a unique linear spectral mixture model to determine sub-pixel abundances of different ashes and combustion completeness measured on the corresponding fire-affected pixels in Landsat data. A new ... Read more
A critical assessment of adaptive ecosystem management in a large savanna protected area in South Africa

Author: Van Wilgen, BW ; Biggs, HC Date: Apr 2011 This paper uses five inter-related topics (the management of rivers, fire regimes, invasive alien species, rare antelope and elephants) to assess 15 years of adaptive management in the Kruger National Park (KNP), South Africa. The importance ... Read more
Drivers of inter-annual variability in Net Ecosystem Exchange in a semi-arid savanna ecosystem, South Africa

Author: Archibald, SA ; Kirton, A ; Van der Merwe, Martina R ; Scholes, RJ ; Williams, CA ; Hanan, N Date: 2009 Inter-annual variability in primary production and ecosystem respiration was explored using eddy-covariance data at a semi-arid savanna site in the Kruger Park, South Africa. New methods of extrapolating night-time respiration to the entire ... Read more
Eco-epidemiological and pathological features of wildlife mortality events related to cyanobacterial biointoxication in the Kruger National Park, South Africa

Author: Bengis, R ; Govender, D ; Lane, E ; Myburgh, J ; Oberholster, Paul J ; Buss, P ; Prozesky, L ; Keet, D Date: Oct 2016 Over the past decade, several clustered, multispecies, wildlife mortality events occurred in the vicinity of two man-made earthen dams in the southern and south central regions of the Kruger National Park, South Africa. On field investigation, ... Read more c b d
Effect of fire season, fire frequency, rainfall and management on fire intensity in savanna vegetation in South Africa

Author: Govender, N ; Trollope, WSW ; Van Wilgen, BW Date: Aug 2006 Fire is important for the maintenance and conservation of African savanna ecosystems. Despite the importance of fire intensity as a key element of the fire regime, it is seldom measured or included in fire records. 2. We estimated fire intensity ... Read more
Field determination of biomass burning emission ratios and factors via open-path FTIR spectroscopy and fire radiative power assessment: headfire, backfire and residual smouldering combustion in African savannahs

Author: Wooster, MJ ; Freeborn, PH ; Archibald, S ; Oppenheimer, C ; Roberts, GJ ; Smith, TEL ; Govender, N ; Burton, M ; Palumbo, I Date: 2011 Biomass burning emissions factors are vital to quantifying trace gases releases from vegetation fires. Here the authors evaluate emissions factors for a series of savannah fires in Kruger National Park (KNP), South Africa using ground-based ... Read more
Identification of toxigenic microcystis strains after incidents of wild animal mortalities in the Kruger National Park, South Africa

Author: Oberholster, Paul J ; Myburgh, JG ; Govender, D ; Bengis, R ; Botha, A-M Date: 2009 The eutrophic process potentially caused by a high urine and faecal load resulting from an unusually high hippopotamus (Hippopotamus amphibious) density in the Nhlanganzwane Dam, Kruger National Park, South Africa, triggered a chain of events ...

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
Increased tree densities in South African savannas: >50 years of data suggests CO2 as driver

Author: Buitenwerf, R ; Bond, WJ ; Stevens, N ; Trollope, WSW Date: Feb 2012 For the past century, woody plants have increased in grasslands and savannas worldwide. Woody encroachment may significantly alter ecosystem functioning including fire regimes, herbivore carrying capacity, biodiversity and carbon storage ... Read more
Long-term effects of fire frequency and season on herbaceous vegetation in savannas of the Kruger National Park, South Africa

Author: Smith, MD ; Van Wilgen, BW ; Burns, CE ; Govender, N ; Potgieter, ALF ; Andelman, S ; Biggs, HC ; Botha, J ; Trollope, WSW Date: May 2012 The long-term effects of changing fire regimes on the herbaceous component of savannas are poorly understood but essential for understanding savanna dynamics. We present results from one of the longest running (>44 years) fire experiments in ... Read more
Relationship between herbaceous biomass and 1km (2) advanced very high resolution radiometer (AVHRR) NDVI in Kruger National Park, South Africa

Author: Wessels, Konrad J ; Prince, SD ; Zambatis, N ; Macfadyen, S ; Frost, PE ; Van Zyl, D Date: Mar 2006 The relationship between multi-year (1989-2003), herbaceous biomass and 1-km(2) Advanced Very High Resolution Radiometer (AVHRR) Normalized Difference Vegetation Index (NDVI) data in Kruger National Park (KNP), South Africa is considered. The ... Read more
Trends in woody vegetation cover in the Kruger National Park, South Africa, between 1940 and 1998

Author: Eckhardt, HC ; Van Wilgen, BW ; Biggs, H Date: Jun 2000 South Africa’s Kruger National Park is one of the largest conservation areas in Africa. In 1940, 1974 and 1998 changes in the cover and density of shrubs and trees were assessed from aerial photographs, and in 1984 and 1996 fixed-point ... Read more
