Description * |
Zonation is a framework for large-scale conservation planning.. Zonation can be used for various purposes such as the identification of near-optimal reserve networks, identification of expansions for reserve networks, assessment of proposed reserve networks and priority ranking for conservation decision support. Features of Zonation that distinguish it from other conservation planning software include Zonation software has been geared towards using large grids as input data. Thus, it is particularly simple to input modeled species distributions (or land cover types) into Zonation. First do statistical habitat models for species, then predict species occurrence across the landscape grid, then feed the grids into Zonation. The Zonation software can be run with relatively large datasets on an ordinary desktop PC. What step in framework The main function of Zonation is analysis of biodiversity distribution and conservation value - economical considerations can only be included via simple land cost layers. Thus, output of Zonation should primarily be seen as one analysis that feeds into a broader land use planning framework where political decisions are made that balance between different land use needs, benefits and costs. Typically one would enter one grid per species (feature). Each cell would have either an observation of population size at that location, or, more commonly, a probability of occurrence or abundance predicted using a statistical habitat model. |

Inputs |
Typical input data of Zonation consists of observed or predicted distributions of biodiversity features (species, communities). There are several optional files (see Zonation manual on http://cbig.it.helsinki.fi/software/zonation/) |

Outputs |
Output of Zonation can be visualized in by two intuitively appealing graphs - the rank priority map and and species-specific performance curves. Zonation produces basic raster files from each run, which can be imported to GIS software for further analysis and visualization. |
