Phylogeny and the sustainable use of biodiversity: an assessment based on the Survey of Economic Plants for Arid and Semi-Arid Lands

Phylogeny and the sustainable use of biodiversity

Geographical coverage

Geographical scale of the assessment Global
Country or countries covered South Africa
Any other necessary information or explanation for identifying the location of the assessment, including site or region name

the assessment occurs in phylogenetic tree space, not in geographic space

Conceptual framework, methodology and scope

Assessment objectives

explore the integration of current-use species and biodiversity option values in assessments of the sustainable use of biodiversity

explore how to combine conservation of phylogenetic diversity (as a measure of option values) and conservation of known useful species.
determine degree to which conservation of current useful species also protects option values.

Mandate for the assessment

Conceptual framework and/or methodology used for the assessment
