Controlled fire experiments date from colonial times in West Africa, although the largest and best-known is located in the Kruger National Park, South Africa. The achievements of these experiments are assessed from examples in Africa, South America and Australia. A less well-known experiment in Zimbabwe was sited at the Marondera Grassland Research Station and ran from 1953 to 1991. Some of the preliminary results on the impact of fire on vegetation are analysed and compared with further vegetation surveys in 2007. Studies on tree growth in this miombo savanna woodland indicate that the plots burned at three- and four-year intervals recovered to greater mean heights than the unburned control plots. There was no significant variation between treatments, suggesting that the few trees that did survive in the frequently burned plots were large specimens. Brachystegia and Julbernadia dominated the plots throughout and after the experiment. Basal area and stocking density were highest in the four-yearly burned plots but there was a high variability throughout the experiment, suggesting that many trees may have attained heights and bark thicknesses sufficient to protect from fire damage. Fire also affected the composition of the herbaceous plant community, but not the number of species. By the end of the experiment some grass and sedge species had flourished while others revealed greater susceptibility to fire, and fire-tolerant species predominated in the most frequently burned areas. The experimental design appeared to cope well with the variability between plots and indicated the soundness of the initial design and its implementation. © 2008 SAGE Publications.Our grateful thanks for the assistance of staff at the Marondera Grassland Research Station, particularly Nation Chikumba, Xavier Poshiwa, Richard Muza Maxwell, Milton Zimondi, Office Busu, Phanuel Mazakata, Dhliwayo Thulandi, Merjury Muswere, Joseph Mutandagayi, Bothwell Tawengwa and the staff over several decades, who carried out the vegetation surveys under often extremely difficult conditions; also the help of Zivanai Tsvuura and James Gambiza, formerly of the University of Zimbabwe. The hospitality and hard work of Gary and June Goss and Andy Roberts made the work in 2007 possible.Peer reviewedSage PublicationsRees, R. M.
