Take a good look at the ordered list of ecological risk assessment
phases. Can you recall what's involved in each of the major parts
of risk assessment?
You will be assigning one of the phases to a variety of steps in
the process.
Read each task in the list below. When you read the task, see if
you can decide which phase it belongs in before reading the letter
in the column to the left.
