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.”

With the recent break in the academic activities at most of the countries’ universities, higher education managers are pressured to come up with ways of completing the rest of the 2016 academic year.

An approach introduced by the University of the Free State (UFS), is the use of online learning platforms.

For the remainder of the year, students will be required to do the majority of their work online. To support students during this time, the UFS has created an Academic Reboot Pack 2.0, which included #8 Habits of Highly successful online students.  

Stay informed and prioritise your work

Make the online environment the top priority in your daily schedules. Be extra vigilant in your studies and use online learning platforms such as Blackboard to check your modules for new announcements and academic information.

You will also need to prioritise between important and less important tasks. This will give you an indication as to which tasks to focus on first.

Optimise your environment and work until you achieve goals

You need to optimise your study environment in a space where you can be productive and study efficiently. Continue working until you have achieved your goals, but also remember to reward yourself when you have reached them.

Staying organised

Remember, you need to stay organised and declutter your environment. It will be best to create a filing system for your paper-based notes, as well as the electronic files on your computer.

Get study buddies and keep a healthy body and mind

Get study buddies as this provides a good opportunity to share knowledge. If you are not sure about something, contact your lecturers via email or on their office numbers.

Lastly, keep a healthy body and mind because you will need to keep going a little longer than anticipated this year.
