Preparing data packages for the Index of Surveys for Assessments (ISA)

This procedure assists proponents and clients in preparing Index of Surveys for Assessments (ISA) data packages to be submitted online via the Environment Online portal as part of an application or referral under Part IV and Part V of the Environmental Protection Act 1986.

The ISA encompasses both:

• Index of Biodiversity Surveys for Assessment (IBSA): being surveys of terrestrial fauna, freshwater aquatic fauna, subterranean fauna and fauna habitats; flora and vegetation; and ecological communities.

This procedure applies to biodiversity and marine surveys conducted in the state of Western Australia.
