MARTIN, D. (1997)

Bvumba: Magic in the Mist.

57 Seiten, Karten Farbfotos.
African Publishing Group, Harare.  ISBN-13 : 978-0797416413


Beautifully illustrated in colour, this new series of pocket guides are more than where and how-to books, although they all give essential information for travellers. They provide a wealth of concise information on the areas they cover, giving a chapter in each book on the subject's geology, paleontology, archaeology, climate and history. Bvumba is the beautifully mountaineous region of eastern Zimbabwe. Sections include the flora and fauna, botanical gardens, golf, walks and drives. The Hwange guide covers the National Park, mammals, birds, trees and shrubs, reptiles, and butterflies; and also has a checklist for mammals, birds, trees and shrubs. The guide to Kariba tells the story of Operation Noah, the rescue of the animals when the lake was damned; and there is a section of Matusadona National Park, on the southern side of the Lake. There are sections also on mammals, reptiles, fish, birds, butterflies and insects, and checklists on mammals, birds, trees and shrubs.

Photographic evidence of fire-induced shifts from dwarf-shrub- to grass-dominated vegetation in Nama-Karoo.

South African Journal of Botany 101 (November 2015): 148-152.


The Nama-Karoo is a semi-arid inland biome in South Africa dominated by dwarf shrubs with grasses, shrubs, geophytes and herbs at varying levels of abundance. The position of the Nama-Karoo/grassland boundary is determined in part by rainfall amount, and in recent years there has been an increase in grassiness, correlated with good rains. This has allowed wildfires, an unusual occurrence, to burn at several sites in the central and eastern regions of the biome. The general effect of fire has been to convert dwarf shrublands to grassland with the extirpation of several nonsprouters species. A collection of photographs describes this effect. It is anticipated that these nonsprouters will recolonise by seed over time, but could be eliminated if fire frequency is high enough to eliminate their seedbank. It is predicted that if grassy conditions persist in the Nama-Karoo, then fire will be an important factor that shapes the Nama-Karoo/grassland boundary.

On the origin of southern African subtropical thicket vegetation.

South African Journal of Botany 2005, 71(1): 1–23.

Volltext (PDF):


The origin and affinities of southern African subtropicalt hicket have been misunderstood and neglected. This formation was only recognised as a biome distinct from savanna and karoo in the mid 1990s. One hypothesis states that it is a young vegetation type, assembled from forest, savanna and karoo elements after Holoceneclimatic amelioration. Others have suggested anancient history for thicket. Here we review fossil and phylogenetic data in order to provide a better assessment of the origins of thicket. Albeit patchy, thefossil data are suggestive of a Palaeogene origin for this formation. A review of molecular phylogenetic data of extant thicket lineages indicated three major patterns:(i)  ancient  Cretaceous  elements,  including Encephalartos and the Strelitziaceae, (ii) basally branching lineages — many of which dominate contemporary thicket — that evolved in the Eocene ( the Celastraceae, Sapindaceae, Didiereaceae, Crassulaceae: Cotyledonoideae), and (iii) lineages derived from adjacent biomes that diversified in thicket in association with Neogene climatic deterioration (e.g. Aizoaceae, Asteraceae). We provide a narrative account of the evolution of thicket, which concludes that it is an ancient formation, extending back at least to the Eocene and derived initially from elements in the forest formations that prevailed in Upper Cretaceous and early Palaeogene times. As a biome, thicket is not uniquely southern African, being part of a formation that was globally widespread in the Eocene and which is extant in many parts of the world. Future research on the origins of thicket should focus on providing dates for major dichotomies as a complement to the rapid emergence of molecular phylogenies, as well as data on the genetic variation in populations of taxa categorised as ancient or young, and widespread or range-restricted.
