Prof Moffett’s latest offering collates hundreds of mountain research material into one accessible reference book.

Prof Rodney Moffett recently published a new book focusing on various scientific articles published between 1808 and 2019. The book, A Scientific Bibliography of the Drakensberg, Maloti and Adjacent Lowlands, has 534 pages and covers material appearing in accredited journals, plus unpublished but traceable reports, documents, presentations, and dissertations.

“The scientific articles range from palaeobotany with 17 entries, to rock art with 502 entries, as well as 252 theses and dissertations,” said Prof Moffett.

He said it took 18 months to compile the book, typing the manuscript himself – mostly at night.

In the foreword, Dr Ralph Clark, Director: Afromontane Research Unit (ARU), says: “This bibliography is a labour of love, and will inspire a new generation to take up the baton for excellent research in this fantastic mountain system. We are proud to publish this under the ARU banner as a contribution to growing and consolidating mountain-passionate relationships in Southern Africa, and to encourage our journey towards developing a holistic understanding and sustainable use of these iconic mountain landscapes.” 

Other books

Prof Moffett is an honorary research fellow in the Department of Plant Sciences at the University of the Free State, and an associate of the Afromontane Research Unit on the UFS Qwaqwa Campus. He was previously Professor of Botany on the Qwaqwa Campus when it was part of the University of the North, retiring in 2000. Since then, he has remained active, publishing scholarly works on ethnobotany and other natural history subjects.

His four recent books, also published by Sun Press, are: Sesotho Plant and Animal Names and Plants used by the Basotho (2010), A Biographical Dictionary of Contributors to the Natural History of the Free State and Lesotho (2014), Basotho Medicinal Plants – Meriana ya Dimela tsa Basotho (2016), and A Field Guide to the Clarens Village Conservancy (2018). A second revised edition of Meriana ya Dimela tsa Basotho –

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.”
