ARU pioneering mountain range-expanding project

All mountains around the world have native and non-native species that are expanding their ranges quite dramatically; however, little research has been conducted towards understanding the long-term redistribution of species and the effects of global change on biodiversity.

The Afromontane Research Unit (ARU) on the University of the Free State Qwaqwa Campus – as part of the Mountain Invasion Research Network – has secured a two-year EU Horizon 2020 project under the Department of Science and Innovation, which will be looking at the mechanisms underlying the success and impact of range-expanding species on biodiversity and ecosystem functioning.

On Monday 19 July 2021, the ARU took a few of its researchers on a scenic helicopter ride to the summit of the Drakensberg for an alpine field-experiment site inspection of the Mont-aux-Sources peak, one of the highest sections of the Drakensberg range. This site has been identified for the project which the research unit will be leading on mountain research.

ARU Director, Dr Ralph Clark, said the project would explore the effects of global change, biological invasions (when species invade new geographic regions), as well as climate and land-use change. He said experiments were needed to explore the various possibilities and to test the extent to which species respond to experimental treatments. The project would therefore be conducting experiments for two years using open-top chambers – causing an increase in temperature of 3 or 4 degrees to what you find naturally – on plant species from lower down to the top of the mountain, to see how they function. “This will give us an idea of whether they will be able to survive in global warming scenarios. If temperatures get warmer, we might start seeing a lot of plants up here that we wouldn’t otherwise find here.”

Dr Clark said little is known about the long-term monitoring of species distribution and the effects of global change. Implementing the project in the Maloti-Drakensberg alpine area will therefore put the area in the global mountain research arena. The elevational gradient in the Maloti-Drakensberg Mountains provides space to explore the key processes underlying the variation in species elevation with climate change. “One of the things we don’t know much about are alpine systems. We are hoping to establish a long-term alpine research site and try to add as many studies as we can. The more science we can bring up here, the more we can know about mountain life. What happens on mountains has a lot of impact on social dynamics.

“This project is looking to see what is driving range expansion. Every mountain has its own context. In the Swiss alpine, fires are not a big factor, but fires are one of the biggest factors on our mountains. Some of our native and non-native species are therefore fire-driven, so as fire increases, you might have them spreading faster.”

“Aren’t auntie and them hungry yet?” Country folk worried about NSH hikers

2014-05-15

About 5 km short of Wortelfontein Guestfarm in the Northern Cape, Rachel Swart is sitting on the porch of her peasant house when four people come walking down the dirt road.

Guests on foot are not a regular sight in this region, because you must understand, Wortelfontein is situated where Hanover lies far behind you and Richmond is still a very long way off.

The four people on the dirt road are the hikers from the University of the Free State (UFS) on their way to Cape Town (on foot) to create awareness for food-insecure students at the UFS.

Adele van Aswegen, Ronel Warner, Ntokozo Nkabinde and Nico Piedt are already on the road for more than two weeks as part of the No Student Hungry bursary’s (NSH bursary) fundraising efforts. The bursary provides assistance to students at the UFS who often do not have enough to eat.

On day 12 of their walk, the plan was that our hikers would stay at Wortelfontein Guestfarm, but unfortunately they took the wrong turnoff. It is precisely at this point where they met Rachel.

“I will show you where Wortelfontein lies. One can easily get lost here,” says Rachel decidedly and points to the straight main road. She ties her baby skilfully behind her back with a towel and tackles the next 5 km together with our hikers.

“It is this kind of support and encouragement that keep us on the road,” says Adel.

Everywhere along the road people are stunned and concerned about the four’s trip and immediately offer their help.

Near Trompsburg, an elderly couple who just heard about the hikers at church, stop next to them and offer them a lift to the next town. They are thankful for the gesture, but have to decline the offer.

Between Trompsburg and Springfontein, Doug offers to take them to Springfontein. Once again they decline the offer.

There was also the uncle who wanted to buy them cool drink and the road workers who cheered them on.

In Colesberg a group of children asked worriedly: “Aren’t auntie and them hungry yet?”
