Vishuis
Vishuis will be trying to win their overall seventh Varsity hostel title on Monday.
Managing his players is of the utmost importance if the University of the Free State’s (UFS) Abraham Fischer Residence (Vishuis) is to claim a fourth straight and seventh overall national hostel title, says Zane Botha, head coach of the hostel team at the UFS.

The Varsity Hostel competition, which will be taking place in Stellenbosch, has been drastically shortened to only three days of rugby because Steinhoff has withdrawn their sponsorship.

If Vishuis makes it to the final, they will play three matches in four days.
They will face the Kovacs of the University of the Western Cape (UWC) on Friday 12 March 2019, followed by the semi-final on Saturday and the final on Monday. The final will take place at 14:00 and will be broadcast live on SuperSport.

“This will be new territory for us. We will have to make good tactical decisions; it won’t be possible for a prop to play for 70 minutes in all three encounters,” said Botha, who is in his third year with the hostel.

The team played three warm-up matches, which they won convincingly. We still have the core of last year’s team, together with some exciting youngsters.
Botha explained that they kept to their strategy of working harder than anyone else on the practice field and during matches. In last year’s final, Vishuis defeated Patria of the North-West University by 55-29, which was the biggest winning margin in the 11 years of the competition. Vishuis walked away with the crown in 2010, 2012, 2013, 2016, 2017, and 2018.

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.”
