An ambitious project for veld management and ecological research, that combines ancient animal lore with state-of the-art technology, took a step forward this week when five eland were released at one of South Africa’s best-known wine estates. (Wednesday 29 July, Somerset West).
The arrival of the eland (Taurotragus oryx) at Vergelegen in Somerset West forms the latest stage of the Gantouw Project. This is a programme of the non-profit organisation Cape Town Environmental Education Trust (CTEET), and has been in operation since 2015 under its Nature Care Fund. The project mimics the historic migration of eland, using them as a natural driver to boost ecosystem diversity.
“Gantouw is a word that is derived from the Koi language and means ‘the way of the eland’,” said Dr Anthony Roberts, CEO of CTEET. “This refers to a path that eland carved into the land over many years as they migrated back and forth from the Cape Flats over the Hottentots Holland Mountains.
“Urbanisation has resulted in fragmented ecosystems, many of which are collapsing. By introducing eland and allowing them to browse vegetation and prevent bush encroachment ‒ one of the main threats to the ecological health of these systems ‒ the characteristic diversity of the veld starts to return and the ecosystem functions more effectively.”
The impact of the eland on the Vergelegen veld will be monitored using drones and spectral imaging, as well as on-the-ground flora and fauna surveys. This will indicate the animals’ grazing preferences, their impact on flora and fauna, and estimations of veld carrying capacity.
The eland group comprises three cows and two neutered bulls, transported from Elandsberg, Wellington. The project will run for five years then be reviewed.
Vergelegen has provided a fenced 10 hectare camp near the hilltop wine cellar, secluded from its hospitality and management operations. CTEET has erected a boma in this camp to shelter the eland and estate management has undertaken to monitor their health. CTEET will conduct research to obtain baseline data as well as ongoing ecological monitoring, and will submit an annual report.
The first phase of the Gantouw Project focused on Cape Flats Dune Strandveld, which is endangered and only found on the lowlands of Cape Town. At Vergelegen the eland will graze on various species of fynbos including renosterbos, osteospermum, searsia, helichrysum, oxalis, various grasses and restios.
Much of the original vegetation at Vergelegen has revived since the estate management embarked on South Africa’s largest privately funded alien vegetation clearing project, said Vergelegen MD Wayne Coetzer. Completed in 2018, the project has restored 2200 hectares of fynbos vegetation, while supporting job creation and skills development in local communities.
The eland research will form part of a PhD thesis by ecologist Petro Botha, the Gantouw Project Manager.
The estate has a long history of collaborating with both local and international universities so that students and professionals can further their education through various projects at Vergelegen, said Coetzer. By end-2018 there had been 24 formal studies: seven undergraduate, eleven postgraduate and six PhD studies. Of these, 19 were from local institutions and five from international institutions.
“We are delighted to be able to play a part in this far-sighted project and look forward to seeing the research findings in due course,” said Coetzer. “We hope the knowledge gained at the estate will help to protect other precious natural habitats.”
Vergelegen was the first Biodiversity and Wine Initiative Champion in 2005, and was awarded the Wildlife and Environment Society of South Africa (WESSA) 2019 corporate award, which recognises the wine estate’s sustained commitment to environmental initiatives.
The Gantouw Project is proudly sponsored as an environmental responsibility project by Quemic, a unique and dynamic provider of integrated risk solutions within the safety and security environment.
