Presentation Transcript

  1. Marxan Functionality, Parameters, Output, and more… the ecology centre university of queensland australia www.uq.edu.au/spatialecology c.klein@uq.edu.au

  2. Conservation Planning • Conservation planning guides decisions about the location, configuration, and management of conservation areas • Conservation areas: areas managed for the persistence of biodiversity and other natural values

  3. Global Hotspots

  4. National Hotspots

  5. Regional Hotspots

  6. not so HOT Hotspots approach… Hotspots DO consider: • Species richness • Threats Hotspots DO NOT consider: • All levels of biodiversity • Complementarity • Cost-effectiveness

  7. 5 6 Pick 2…based on number of species 3

  8. Represent all species…

  9. OPTION 1 OPTION 2 $$$ $$$$$ + + $$ $$ = $$$$$$$ = $$$$$

  10. SYSTEMATIC Conservation Planning A Few Fundamental Principles: • Comprehensive Representation • Complementarity • Cost-effectiveness The whole is more than the sum of the parts!

  11. Marxan • Tool help solve problems • Marxan software (Ball and Possingham, 2000) FREE - http://www.ecology.uq.edu.au/marxan.htm • Used by over 600 organizations in about 100 countries to support conservation decisions • Minimizes the cost of a reserve system subject to the constraint of including a portion of all biodiversity features (i.e. species, habitats)

  12. Today you will… • Explore output files • Explore sensitivity of results to parameters • boundary length modifier • targets • repeat runs • status • cost

  13. Conservation Targets

  14. Boundary Length Modifier

  15. Individual Summed Solutions = + Repeat Runs
