Plot sampling is a method of abundance estimation. Generally plot sampling assumes that on a given survey you will identify all of the animals in the survey region with probability one . From this, plots are selected from the entire survey region and sampled, an estimate can then be made using the Horvitz-Thompson estimator. This is a useful method if it is certain that all of the animals in the sample area will be sighted on a given survey.
