These are typical headlines from the newspapers describing problems that are all to common in society these days but they were written to describe not troubles between people but troubles faced by the creatures that live in our streams and rivers. See if you can link these headlines with the following stories.

You could probably compose some other headlines that looked as though they were people problems but actually referred to existing or possible troubles in our waterways. Imagine yourself as a detective trying to solve these cases.
You would have to get some background information to solve the mystery.
are some of the basic information environmental detectives have to uncover.

Check out the 17 key Ecology Factors which you, as a River Detective, will need to use when investigating your local river or stream.
Next, head over to the River Detective Case Histories. These are fascinating tales written by Dr. John Walsby, which have appeared in his weekly column "Nature Watch" in the New Zealand Herald. As a training exercise, consider how each of the Ecology Factors is important in each of the River Keeper case histories.
With this training behind you, pick a critter or subject to investigate and write your own Case History.
