Abstract
The proportion of the total aerial dry weight of Equisetum sylvaticum devoted to spore producing and supporting structures does not change in the first 6 years of postfire succession: the ecological strategy remains constant. However, the stem and branch lengths of sterile shoots, their time of appearance, and the distribution of dry weight between sterile shoots do vary during the same period, indicating changes in ecological tactics. The tactical changes appear to be a response to increasing competition. Clones of E. sylvaticum survive repeated fires by means of the deeply buried rhizomes and are evidently very long-lived.
