This is a supplemental resource from Agent-based and Individual-based Modeling: a practical introduction by Railsback and Grimm (2012). This is an ODD description of the BEFORE beech forest model, from section 18 of the book.
This document describes the BEFORE beech forest model described in Section 18.3. It is taken from an appendix to:
