Designing Contiguous and Minimally Fragmented Nature Conservation Reserve Networks

Abstract

This dissertation is built upon some recent studies which dealt with two important spatial criteria, namely reserve contiguity and minimal fragmentation, using graph theoretic approaches and linear integer programming. The optimization methods presented in those studies are modified to improve computational efficiency of the solution procedure, which may be particularly important in moderate and large scale applications. The methods developed in this study are applied to state-endangered and threatened bird species in Illinois and an efficient reserve system is determined at State level while conservation goals at regional level are taken into account.
