WebIn general, the results indicate a preference for the line transect method over strip transect on the basis of bias and efficiency. J. WILDL. MANAGE. 49(4):1012-1018 Applied ecologists faced with the problem of estimating the size (N) or density (D) of a pop-ulation frequently consider the use of strip or line transect sampling (see Burnham and An- WebThe strip-transect technique involves counting the number of birds detected within a fixed distance of transect lines, and the results are expressed as a simple index of abundance, viz. average numbers per transect (Bibby et al. 2000). The technique assumes that birds are equally detectable over time.
