From whichever direction one approaches Knysna, the estuary becomes the focal point. It is the heart of Knysna. But it is more than that. Just as it is a ‘life support system’ in the economies of Knysna and the Garden Route, it was a key resource in the lives of humans who settled here thousands of years ago. Its unique setting sets it apart as the most biologically diverse estuary in South Africa, but also as a ‘place’ to which we easily become attached - whether it be for sailing, fishing or taking a quiet walk while the sun sets.

The estuary and the setting in which it is situated, are in our care. How can we all become more attached to the estuary and committed to caring for it?

While searching the saltmarshes for interesting plants and animals Mark Read began to wonder if there was a comprehensive text that would encourage and help people to learn about the estuary. In discussion with Charles Breen and Alan Whitfield, it was confirmed that such a book had yet to be written. And so, the journey to conceptualizing the book, drawing in sponsors and authors began.

This book brings knowledge of the Knysna Estuary together in a format that is useful to as wide a section of society as possible, targeting learners, students, scientists, managers and the general public. Our primary goal is for the wealth of information on the natural history of the Knysna Estuary to contribute towards creating an informed society.

In so doing, the book will encourage interest and support for the wise use of the estuary, now and into the future. But it does not stop there, because knowledge of the Knysna system biota and ecological functioning has direct relevance to other South African estuaries and even further afield.

The book has twelve chapters written by experts in their field, most with a strong knowledge and direct research experience of the Knysna system. The aim throughout is to enable and encourage readers to appreciate life within the estuary, understand its structure and functioning, and empower people to communicate its value and conservation importance from an informed position. And, above all, to ensure that we tread lightly, leaving something of great value for others to enjoy.
