Though satellite imaging and aerial surveys give a rough idea of changes in animal and plant life, the most detailed data still have to be collected on foot. This is all very well for those places where skilled botanists and zoologists swarm in the undergrowth, but what about everywhere else?

CyberTracker is a hand-held device that lets users record what they see quickly and easily, and then plots maps showing exactly where the observations were made, using the Global Positioning Satellite navigation system.
