This book was first published in 1977 and is widely recognized as a
classic in the field. It is the "bible" for wildlife managers
everywhere. It is an introduction to the methods and analysis of
vertebrate populations for ecologists and wildlife managers as well
as students of these subjects. A wide range of examples drawn from
mammals and birds in different parts of the world is used to
illustrate these methods. The book shows how population analysis
can be applied to practical problems of wildlife management such as
reducing a population, stimulating it to increase or taking from it
a sustained yield. In order to make this complex subject as simple
as possible, the methods for analysis described in this book are
those which use elementary algebra and statistics rather than
complex mathematics. Graeme Caughley studied the interactions
between large mammalian herbivores and the environments they
occupy. The pattern of population growth that can be predicted
theoretically from such a relationship is both complex and
variable. The animals will either erupt, crash, and then converge
to a more stable density, or the population may oscillate
indefinitely, the densities of plants and animals being locked into
a stable limit cycle. He argued that the dynamics of mammalian
herbivore populations are comprehensible only in terms of an
interactive relationship between the herbivores and vegetation. He
further argued that efficient management of such systems requires
an understanding of the underlying mechanisms whereby the animals
react to the plants and in turn the plants react dynamically to the
effects of grazing. He was best known for his contributions to the
understanding of herbivore-vegetation dynamics in the New Zealand
high country, the Himalayas, southern Africa and the semi-arid
rangelands of Australia. His research was distinguished by rigorous
design, execution and analysis, so that the conclusions had
generality beyond the particular species studied. Since he chose
topics that combined theoretical interest and practical
application, he also influenced important management policies -
deer populations in New Zealand, kangaroos in Australia and the
conservation of large mammals in Africa and North America. He had a
major influence on thinking and practice in the field of vertebrate
ecology and wildlife management throughout the world.
