We model collapsible and ordered pushdown systems with term rewriting, byencoding higher-order stacks and multiple stacks into trees. We show a uniforminverse preservation of recognizability result for the resulting class of termrewriting systems, which is obtained by extending the classic saturation-basedapproach. This result subsumes and unifies similar analyses on collapsible andordered pushdown systems. Despite the rich literature on inverse preservationof recognizability for term rewrite systems, our result does not seem to followfrom any previous study.
