Methods for mark and recapture can be applied for subsampling to give flexible sampling designs for wild populations where separate segments can be sampled independently. In area sampling, the area inhabited by a population is separated into quadrates and a sample of quadrates is selected with known probabilities; this insures a random sample of quadrates, but good estimates of abundances in the quadrates would be difficult to obtain for mobile animal populations without application of a method designed for such populations. If mark and recapture is applied in quadrates selected using area sampling, the result is a subsample with variation between quadrates and variation within quadrates. An estimator of population abundance is developed for subsampling using mark and recapture, and important consequences for design of such surveys are discussed.
