Item Details
SUMMARY

Marxan is a systematic conservation planning tool, which generate the optimized portfolio of land parcels with given conservation goal. It does not model LULC change, but rather identifies the preferable future LULC. Also, it could only model 2 LULC class, i.e. protected vs. not protected.

Alternatively, the Marxan output can be used as restricted areas input with other LULC modeling tools.

INPUT - REQUIRED ?Spatial? land planning unit map, cost map ?Non-spatial? target abundance per unit, protection goals
INPUT - OPTIONAL Planning unit boundary lengths, biological constraints, spatial clustering, species penalty factors
OUTPUT ?Spatial?Portfolio of suggested protection area, as either vector or raster. ?Non-spatial? summary statistics of the scenario plan, including species protected and area protected etc.
HOW ARE SCENARIOS DECIDED?

Amount: User-defined goal on area and conservation target

Location: Portfolio of planning unit, which balances the goal and the cost

COST free
FORM Standalone application
CAN I ALTER THE MODEL? Yes
SCALE/RESOLUTION No restriction
REQUIRE GIS TOOL TO RUN THE MODEL? No. However, pre- and post-process require GIS tool.
