The nature series with the latest news and information on our wildlife, with Su Ingle and Michael Jordan

A new series with a new presenter. Joining Su Ingle is naturalist Michael Jordan, who this week comes across a pond full of squabbling toads and finds out what the fighting is all about. And Michael asks you to send in information on your own wildtrack pond. Su looks at the profusion of wild flowers in a traditional English meadow, and tells you how to create your own area of meadowland in your back garden. And a special report for Wildtrack from David Attenborough, who sets off on an epic sea voyage in search of the wildlife of the sub Antarctic.

Discs
The video-boom is here - sales of video-cassette recorders are rocketing. But three giant electronics companies are crossing their collective corporate fingers about a brand new video-player which they've risked millions in developing.
The videodisc player will soon be in the shops, with top feature films - and much else - available on shiny discs for much less than the current price of a video-cassette. But unlike the video-cassette recorder, you can't record on to a disc - so they're no good if you just want to watch Play for Today tomorrow.
Kieran Prendiville and Michael Rodd give us a taste of what the videodisc can do-and talk to the three companies who have spent fortunes in an attempt to win the lion's share of a market that just might not exist.
