Evolving governance arrangements in multi-tenure reserve networks

Multi-tenure reserve networks (MTRNs) aim to connect areas managed for biodiversity conservation across public and private land (for example biosphere reserves (BRs) and conservation management networks (CMNs)). A key function of MTRNs is facilitating communication, information exchange and management activities between land managers of differing tenures not usually in contact with each other; governance arrangements are therefore crucial. Australian MTRNs vary greatly in their goals and measures of success, criteria for entry, ecosystems targeted, geographic extent and financial arrangements. The successful operation of a MTRN is likely to be influenced by a manager's confidence in the governance model/coordination arrangements (Belcher & Wellman 1991). We analysed the organizational structure of three Australian MTRNs (Fig. 1) including the objectives and role of the coordinating body, entry requirements, goals and measures of success, restrictions placed on the geographic or ecological extent of the network and financial arrangements. We highlight how substantial changes in governance arrangements have occurred for two of three networks studied, suggesting a fluid evolution of MTRN structures is likely.
