The principal objectives and scope of the current study are to examine how eco-infrastructure can be sustained within a multiuse area of a municipality in a transition economy in a way that protects habitat, ensures public access, and is adequately funded and managed. The case of Ulcinj, Montenegro, is presented for this purpose. The methodology employed reviews the available literature and best practices to identify possible models, and then considers them in the context of Ulcinj for their relevance and feasibility. The comparative analysis identifies six examples of nature preserves that successfully protect habitat, ensure public access, and operate sustainably with adequate funding and management. The examples are taken from California, Croatia, Chile, Bolivia, Costa Rica, and Guatemala.
