Uncertainty in the assessment and management of biodiversity and ecosystem is derived from (1) uncertainty of our understanding about impact on biodiversity, (2) insufficiency in scoping, and (3) uncertainty that inherent in ecosystem. To cope with the uncertainty, effective scoping with appropriate indicators and quantification of impact is important, as well as adoption of adaptive management with precautionary principle that has been used in ecosystem management. Further challenges are discussed concerning uncertainty in the biodiversity assessment.
