Athletes show huge promise at Varsity Athletics meeting
Hendrik Martens of the Kovsies earned a silver medal in the 200m at theVarsity Athletics meeting in Pretoria.
The University of the Free State (UFS) dominated affairs in the middle distance at the first Varsity Athletics meeting of the year where they bagged no less than three gold and two silver medals.
The meeting took place on Friday 2 March at the Tuks Athletics Stadium in Pretoria. 

Middle distances have produced Olympic athletes for Kovsies such as Johan Cronjé and Rynardt van Rensburg in the recent past. 

Kovsies produced winners
The Kovsies produced both the men’s and women’s winners in the 800m. They were Ruan Jonck (1:50.06) and Ts’epang Sello (2:07.15) respectively.

Bennie Prinsloo finished in second spot.

In the 1500m for women, two Free State students also took the first two spots. Tyler Beling, who is just18 years old, dominated and finished six seconds (04:39.47) before Lara Orrock (04:45.2) in second place.
Orrock is also a first-year. Beling and Orrock were two of eight first-year students in the team of 25 athletes.
Apart from a first place in the men’s varsity mixed medley relay that was unfortunately the only gold medals the Kovsies managed on the night. 
They ended in fourth position behind Tuks (first), NWU (second) and UJ (third).

Gold, silver and bronze medals
There were, however, several silver and bronze medals.

Hendrik Maartens (second) and Oratile Sethlabi (third) gave good performances in the 200m. 

In the long jump for women, Maryke Brits grabbed second place and Norbert Ponisammy did the same for men. Interestingly, both also compete as sprinters.
Sefako Mokhosoa was the second best triple jumper and Nadia Meiring and Juan Muller both earned third spots in the hammer throw.

The second Varsity Athletics meeting is scheduled for 23 March 2018 in Pretoria.

Fire as a management tool questionable in arid and semi-arid grassland areas

The influence of fire on the ecosystem in the higher rainfall ‘‘sour’’ grassland areas of southern Africa has been well established. However, less information is available for arid and semi-arid ‘‘sweet’’ grassland areas, says Prof Hennie Snyman, Professor in the Department of Animal, Wildlife, and Grassland Sciences, about his research on the short-term impact of fire on the productivity of grasslands in semi-arid areas.

Sour and sweet grassland areas can be defined as receiving either higher or lower than approximately 600 mm of rainfall respectively. In quantifying the short-term impact of fire on the productivity of grasslands in semi-arid areas, a South African case study (experimental plot data) was investigated.

“Burned grassland can take at least two full growing seasons to recover in terms of above- and below-ground plant production and of water-use efficiency (WUE). The initial advantage in quality (crude protein) accompanying fire does not neutralise the reduction in half of the above-ground production and poor WUE occurring in the first season following the fire.

“The below-ground growth is more sensitive to burning than above-ground growth. Seasonal above-ground production loss to fire, which is a function of the amount and distribution of rainfall, can vary between 238 and 444 kg ha -1 for semi-arid grasslands. The importance of correct timing in the utilisation of burned semi-arid grassland, with respect to sustained high production, cannot be overemphasised,” said Prof Snyman.

In arid and semi-arid grassland areas, fire as a management tool is questionable if there is no specific purpose for it, as it can increase ecological and financial risk management in the short term.

Prof Snyman said: “More research is needed to quantify the impact of runaway fires on both productivity and soil properties, in terms of different seasonal climatic variations. The information to date may already serve as valuable guidelines regarding grassland productivity losses in semi-arid areas. These results can also provide a guideline in claims arising from unforeseen fires, in which thousands of rands can be involved, and which are often based on unscientific evidence.”
