This chapter presents a general framework for identifying, scoping, and planning studies of en- vironmental problems.

Har- vesting or managing populations over long periods can also produce un- desired cumulative genetic changes (Chapter 11.

SCOPING THE PROBLEM Scoping involves bringing together all interested parties public, busi- ness, government, and scientific so that they can interact and express their views before major actions or studies are initiated (Council on En- vironmental Quality, 19781.

Early scoping can help to identify the im- portant issues and potential environmental effects associated with planned actions.

It can help to define scientific objectives and guide the design of ecological studies.
