Virtually any exercise in ecology will require some knowledge of the techniques for carrying out a census of population numbers. This practical text outlines clearly, with worked examples, the main techniques used by field ecologists to enumerate plants and animals.
This is a comprehensive and accessible guide to the many varied techniques for undertaking surveys for general biodiversity levels and for specific habitats and species. Sutherland runs through the basis of each technique, the best situations to apply them and the limitations and constraints, all in his usual clear and easy to follow approach. Even the statistical side of things is surprisingly easy to follow, although I did still need to read those bits a few times before it sunk in (stats have never been my strong point).
