Book Description

With about 1800 native species of trees in southern Africa, plus several hundred more that have been introduced, the challenge of identifying even a small portion of these is a problem for botanists and laymen alike. Most tree identification guides require one to be familiar with the family from which a particular tree comes, but the authors have developed 43 groups into which trees can be categorised, according to easy-to-observe characters, such as leaf shape and form, presence or absence of thorns or prickles, or whether or not latex is present. By utilizing their simple and logical way of looking at trees, it is possible to arrive at a likely family and, from there, to move towards positive species identification. The title starts by defining key characters, such as leaf arrangement and venation pattern, before considering secondary identification characters such as bark, seeds, fruit and flowers. Once one has an understanding of what to look for when examining a new tree, it is possible to move on to the 43 groups for a more detailed breakdown of the defining characters. Using iconic graphics, full-colour photographs and distribution maps, the text takes the reader through a logical process of tree identification.

Editorial Reviews

From the Publisher

Tree identification is generally perceived as difficult, all
the more so in a botanically diverse region such as southern Africa, where
about 2 100 species occur naturally, not to mention several hundred more
that have been introduced from elsewhere in the world.

‘How to Identify Trees in Southern Africa’ – a first of its kind for the
region – provides the background knowledge essential for tree
identification. The book promotes an approach that will equip readers to
use any field guide to trees with greater ease and more confidence.
Starting with the basics of plant form, it systematically uncovers the
structure of trees to enable a clear understanding of what to look for when
trying to identify an unknown tree.

The book is divided into two parts: Part One, well-supported with colour
illustrations and photographs, describes the various parts of a tree and
their significance for identification. Part Two features a key to 43 tree
groups based on easy-to-observe stem and leaf features. As a first step
towards identification, the group-recognition approach has proved to be
more helpful to the layperson than the often-used formal botanical
families. An icon is used to depict the principal characters of a group,
thus making it easier for the beginner to record and conceptualize tree
diversity. Group accounts present explanatory notes on group characters and
tips on species identification. A selection of tree species is described
and illustrated, and a list of all the southern African plant families
represented in each group is supplied (greater coverage of species is
featured in the authors’ ‘Field Guide to Trees of Southern Africa’, 1997).
