Electron Escape from Solid Targets, of the survey region (the shaded rectangles) was searched so if we were sure every plant in the shaded rectangles was detected, it would be reasonable to assume that about an eighth of the plants in the field were detected.

It also provides a natural link to more complicated methods for open populations, which we discuss briefly in this book, but which are crucial for the management of wildlife populations.

Applications of Ion-Selective Electrodes,we assume we know it, and with distance sampling methods (Chapter 7) we assume “capture” is certain on the line or point. Depending on the application, these assumptions may be quite reasonable; when they are not, removal or mark-recapture methods can be useful. With mark-recapture methods, animals
