| Counting Animals | |
| 1978 Full Book | |
The first edition of this Handbook was produced in December 1975. However, during the last two years more information on techniques of counting animals has become available This revised edition includes some of the more recent research findings on this topic and at the same time various corrections of error and other small changes have been made to the original text. Rather than alter the original text, the extra information in presented as four Appendices which cover the following subjects: (1) the study of movements and distributions, (2) training observers, (3) more about counting bias, and (4) operational procedures and check sheets for censuses. The first and third appendices include further references not given in the main list of references. Although this handbook gives special emphasis to methods of aerial census, it must be appreciated that he methods and analyses are similar, if not the same, for ground counts. This is the reason why the section on ground counts is relatively brief. |
