ResNet and Surrogacy are companion programs which respectively address the biodiversity reserve selection problems of using surrogate measures of biodiversity and of prioritizing places based on these measures.
The general place-prioritization procedure of ResNet 1.2 was first outlined in the late 1980s. It presumes a given area that has been divided into cells (based perhaps on geographical coordinates or ecosystem boundaries), a record for every cell of the presence or absence of every defined species, and a definite target for representation, such as the minimum number of times any species must be represented by the selected cells. The main virtue of this package is computation speed. It is fast enough for use to generate new plans even with relatively large data sets during a planning meeting. The ResNet algorithms emphasize the selection of places containing rare species (the principle of rarity), and places which add as many under-represented species as possible to a set of selected places (the principle of complementarity). The ResNet algorithms are particularly pertinent to reserve designs for conservation of rare species. User control over composition of each selection set is determined by initialization options and other options such as area and cost constraints. Spatial solutions presented in ArcView provide a starting point for further planning considerations. ResNet has been systematically compared to SITES. The set of selected reserve elements are displayed in ArcView GIS. Incremental additions to the selected set, due to progressively relaxing area constraints for example, are easily displayed in a single view.
