MEASURING BIODIVERSITY VALUE
A note on grids and data
Biodiversity value in theory
: identifying a fundamental currency of value to people
1.1
Best estimates
:
using genealogy to predict genetic or character richness
Principles
Phylogenetic & taxonomic measures
Lack of phylogenetic information

1.2
Popular estimates
:
using species richness
Species richness
Comparing 'indicator groups'
Images building up overlays for butterflies and birds
Images showing overlay comparisons among butterflies, birds and dragonflies
Images showing overlay comparison of Pinaceae and Fagaceae
1.3
Practical estimates
:
using higher taxa or environmental variables as surrogates
Higher taxon richness
Comparing biological & environmental surrogate maps
Image showing plant family richness
Image showing overlay comparison between plant family richness and primary productivity
1.4
Relationship among estimates
:
a scale of surrogacy for mapping more of biodiversity value at lower cost
2
MEASURING RARITY & ENDEMISM
Measuring rarity or endemism from range-size data
2.1
Discontinuous measures
:
using thresholds to include only the rarest species
2.2
Continuous measures
:
weighting by range size

ASSESSING CONSERVATION PRIORITY &
GAP ANALYSIS
Values, goals and priorities
3.1
Area-selection methods
Quantitative area-selection methods
Hotspots of richness, hotspots of rarity & complementary areas
Comparison of hotspots & complementary areas
Algorithms for choosing complementary areas
3.2
A sequential approach to viability and threat
Prescription
: values and goals
Preselection
: viability etc.
Selection
: efficiency
Prioritisation
: threat etc.
Postselection
: inter-active exploration of flexibility
Reiteration
