Crown profiles of 260 Scots pines in central Finland were measured using a new method developed in the study, and a simple model for crown shape, belonging to the Lame curve family, was derived using these data. Relatively accurate estimates of the crown maximum radius and its height, parameters needed for application of the model, were obtained using breast height diameter (dbh) and tree height. Results suggest that the model could potentially be used to generate the crown shape directly from routine stand data. (C) 2004 Elsevier B.V. All rights reserved.
