This paper develops an approach to estimating population abundance from line transect surveys which uses a calibration survey to estimate the detection function which is then employed as a weight function in constructing the abundance estimate. Nonparametric methods of estimating the detection function via local regression and via a kernel density estimator are considered. The proposed methods are evaluated using a set of Western Australian plant data and weed enumeration data.
