Abstract
In this proposal we use the concept of ecosystem networks in a region as a tool for planning conditions for biodiversity. The aim is to develop an approach for integrating ecological and economical indicators in decision making on the spatial development of nature in multifunctional landscapes. With this information, regional decision-makers can consider ecosystem networks as a potential regional investment in both biodiversity and economic values, and compare alternative design options. The scale level we focus on is the regional level (in the order of size of 25-75.000ha). We build on a preliminary design method for ecological networks, based on metapopulation and landscape ecology. We improve the scientific basis of that method with existing knowledge and databases, including those of the Stimuleringsprogramma Biodiversiteit. We will use knowledge taken from existing research on the economic capital delivered by nature and landscape of a region (with an emphasis on recreation and real estate values), and on costs of developing nature. An attempt will be made to relate the economic value to the total area, type and spatial configuration of ecosystems in a region. We then will develop a simple tool for decision-making, in which the linkages between variable regional investments in ecosystem networks and the expected economic and conservation values are made visible for decision-makers.
