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
not so HOT Hotspots approach… Hotspots DO consider: • Species richness • Threats Hotspots DO NOT consider: • All levels of biodiversity • Complementarity • Cost-effectiveness
5 6 Pick 2…based on number of species 3
OPTION 1 OPTION 2 $$$ $$$$$ + + $$ $$ = $$$$$$$ = $$$$$
SYSTEMATIC Conservation Planning A Few Fundamental Principles: • Comprehensive Representation • Complementarity • Cost-effectiveness The whole is more than the sum of the parts!
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)
