|Tool name *||MARXAN|
See Watts et al., 2009 for an extension of of Marxan called Marxan with Zones. Marxan can assist with the evaluation of existing reserve systems to identify gaps in biodiversity protection, identify areas to include in new reserve systems, and provide decision support by producing a number of different options that meet both socio-economic and conservation objectives. Marxan has also been used to support multiple-use zoning plans that balance the varied interests of stakeholders.

|What step(s) in analysis framework||1a, 1b|
|What step(s) in Governance framework|
Input parameter file, planning unit file, conservation feature file, conservation feature distribution file, block definition file (optional) and boundary length file (optional). Marxan does not consider uncertainty in the data so the quality of what you put in is reflected in the results generated.

Terrestrial, freshwater, and marine systems
•Identify areas that efficiently meet targets for a range of biodiversity features for minimal cost•Use the principle of complementarity to select planning units which complement the conservation area network (the whole is more than the sum of its parts);•Meet spatial requirements such as compactness of a reserve system;•Include data on ecological processes, threats, and condition;•Identify tradeoffs between conservation and socio-economic objectives; and•Generate a number of very good solutionsOutput files can be of the csv type which Arcview can read in directly.
