Shortcomings that the NSW Dept of Environment and Planning have observed in EISs:

• presentation too complex or technical
• insufficient information
• obviously flattering presentation
• poor information base
• omission of information
• irrelevant information
• poor and unclear presentation
• inadequate identification of impacts
• inadequate identification of indirect and far reaching impacts
• complicated systems of value judgements

Time constraints can also be a problem. Ecologically important but occasional or episodic phonomena, such as the breeding behaviour of organisms or floods in watercoruses can be missed in short surveys. Short studies present a static view of an ecosystem and neglects variation of distribution and abundance of species.
