AimsAims
To:
Promote discussion about measurement of biodiversity
Introduce methods of data analysis
Explore how such activities support A Curriculum for Excellence

AimsAims
A local authority has a limited budget for conservation projects. You are asked to select one area which should be protected. So:
In groups of 6 examine the data and discuss which area(s) show the greatest biodiversity
Draw up a list of the factors which you might take into account when making your decisions

How do we quantify rarity?
Define a quantity ‘Range-size rarity’, RSR,
RSR = 1/x where x is the number of areas in which a species is found to be present

Summary/conclusionsSummary/conclusions
Measurement of biodiversity is not trivial!
Before decisions about which area(s) to conserve are made, a number of factors need to be considered. These include species richness, range-size rarity and taxic richness
Species richness and taxic richness are useful indicators but their usefulness depends upon the quality of data collection
