Dr Falko Buschke says the iconic sandstone cliffs of the eastern Free State are key to protecting wild plants and animals from climate change.
The iconic sandstone cliffs of the eastern Free State are often the focus of paintings and postcards. Now, new research shows they also protect wild plants and animals from climate change. This finding is the outcome of a collaborative research effort by the University of the Free State (UFS); BirdLife South Africa; the Vrije Universiteit Brussel and KU Leuven, Belgium, which has recently been published in the journal Biological Conservation.

Mountains key for climate change mitigation

The study, led by Dr Falko Buschke from the Centre for Environmental Management UFS, used satellite data from NASA to track the ecological effects of wet and dry seasons, including the record drought of 2015/16. This showed how vegetation on the cool and moist mountain slopes was less affected by dry spells.

The complex physical terrain allows moisture to accumulate in the shaded parts of the south-facing slopes and ravines. This creates cool and moist habitats for plants and animals that wouldn’t survive in the rest of the hotter and drier landscape.

The team also discovered that these positive effects of mountains do not end at the foot of the mountain, but extend at least 500m into the flatter lowlands. “Presumably because water and nutrients accumulate in these surrounding buffers due to run-off,” says Dr Buschke.

Butterflies find safety on mountains

In addition to their high-tech analysis of the area, the team also relied on old-fashioned fieldwork to monitor butterflies over two years. “The data showed us how these insects find safety on mountains during harsh climate conditions and can then recolonise the rest of the landscape after conditions improve,” explains Dr Buschke. “This gives us clues on the best way to protect nature,” he adds. 

This study took place in the Rooiberge-Riemland Key Biodiversity Area (KBA), an area significant for maintaining global biodiversity. Several species of insects, reptiles, birds and mammals here occur nowhere else on earth. “If they disappear here, they will go extinct from the whole planet forever,” says Dr Falko Buschke. 

Despite its ecological significance, most of the area is covered by commercial farmland. So, the next stage of the project is exploring ways of protecting these important habitats while ensuring that farmers can continue producing food and supporting rural livelihoods. 

“Farmers hold the key to preserving biodiversity,” says Dr Buschke, “so conservation scientists need to work closely with them to ensure that we protect species for future generations.”

UFS awards centenary bonuses to staff
2004-11-25

The University of the Free State (UFS) will award a special Centenary bonus of R3000 (three thousand rand) to all qualifying staff in December 2004 .

As far as general salary increases for 2005 are concerned, plus an inflation- based linked salary increase adjustment of 1,4 percent and a further 4,6 percent salary increase as a final dividend from the financial turn-around strategy that began in 2000, will be instituted .

  • The final percentage salary increase is dependent on whether the expected government subsidy, of which the UFS must still receive notification from the Department of Education, is received.
  • , if the expected government subsidy realizes .
  • In addition, the salaries of service workers in low remuneration groups, as well as full professors have been adjusted retroactively to 1 January 2004. This restructuring was agreed upon to address market-related backlogs for these two groups , who display the biggest backlog relative to comparable institutions . A similar professional bench-marking exercise for support service staff has not been finalised.

This agreement was signed on Wednesday 24 November 2004 between the UFS Council and the UVPERSU-NEHAWU Joint Forum regarding salary negotiations for 2005.

“With this Centenary bonus and the significant above-inflation salary increase payment the UFS wants to pay recogni se tion to the sterling role that staff

have played in a difficult period of transition and fast growth and the contributions that they made to promote excellence at the UFS to a

university of excellence,” said Prof Frederick Fourie, Rector and Vice-

Chancellor of the UFS.

He said that the extra payment of this final 4,6 percent increase due to benefit from the financial turn-around strategy means that in real terms average salaries at the UFS had increased over the past 3 to 4 years by well over more that the 15 percent target that was set initially.

According to Prof Fourie all staff members who were in the employ of the UFS on UFS conditions of service on 15 November 2004 and who assumed duties before 1 October 2004, will qualify for the bonus. The same criteria will apply as for the 2004 bonuses.

However, there are some exceptions who do not qualify for the bonus eg learning facilitators, professors extraordinary, affiliated lecturers, departmental assistants, laboratory assistants, student help, all staff appointed for less than 20 hours per week, persons who are paid on a claims basis etc.

“Although the UFS’s actual subsidy amount is not yet known, an increase of 6,6 % in the total remuneration costs was budgeted for in the budget serving before the Executive Management and Council. It was further agreed with the UVPERSU-NEHAWU Joint Forum that the first 6 % increase will be used as general pensionable salary adjustment with implementation date 1 January 2005,” said Prof Fourie.

According to Prof Fourie the agreement also applies to all staff members of the Qwaqwa and Vista campuses whose conditions of service are already aligned with those of the main campus.
