Arbor tree plant
To celebrate National Arbor Week the University of the Free State has embarked on a drive to plant 150 trees during the month of September

If you’ve wondered whether Arbor Month was important, you only have to look at the destruction and long-term damage that deforestation causes to the environment and the world’s inhabitants. To observe National Arbor Month, the University of the Free State’s has (UFS) kick-started a drive to plant 150 trees during the month of September.

To launch this initiative, the Rector and Vice-Chancellor, Prof Francis Petersen, alongside members of the rectorate, assisted the University Estates team in planting the first 10 of 100 trees at the Bloemfontein Campus on Wednesday 4 September 2019. A total of 50 trees will be planted on the Qwaqwa Campus.

Towards a sustainable future

“We have gone through periods of drought in the Free State that have severely impacted not only the plants but the trees on our campuses. The idea is to emphasise sustainability, and as a university, we believe that sustainability is important. As an education institution, we have to look at the generations that are still to come to our campuses,” said Prof Petersen.

He urged the Kovsie community to ensure that all practices across the campuses are linked to global standards of sustainability. “As we develop over the next couple of months and years, we will get much closer alignment between what we are doing as a university and the Sustainable Development Goals.

Drought-resistant man-made forests

Clusters of mini forests across the campuses will be created with a variety of trees including the karee, white karee, white stinkwood, and wild olive. These indigenous trees can adapt well to different soils including those that are poorly drained.

Celebrating Arbor Week

This year’s campaign was held under the theme Forests and Sustainable Cities. As part of the celebration, University Estates made a commitment to the environment by embarking on the green initiative which includes other project such as the upgrade of Red Square on the Bloemfontein Campus.

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.”
