Potential contributions of capture-recapture to the estimation of population growth rate in restoration projects.

摘要

Estimation of population growth rate is central to evaluating a restoration plan. The follow-up of individually recognizable animals, known as capture-recapture, is a means of collecting the data necessary for such estimation. This alternative method can easily be put in practice during restoration projects because reintroduced animals can be tagged before release. Population growth rate can then be estimated directly from capture-recapture data (Pradel, 1996). The method also enables evaluation of the demographic processes responsible for variation in population size. We examine three examples and conclude with a discussion of the potential of this approach.
