...apparently it's axing from ITV1 simply forced BBC1 to bring it back from the dead...and their nature documentary team will be on board for the future series!

I'm personally pleased to see this returning...it was left on a cliffhanger and now we get to not only see what happens next, but do so without worrying there's only so many shows remaining!

BBC have got nothing to do with this...

Well it seems that the BBC's only involvement in it is that BBC Worldwide have partly funded the new series (although I don't know what's in it for them).

Apparently series 4 will be aired on ITV, and then series 5 will be aired (at first) on Watch.

Yes that's the same article I read...and seeing as Watch mainly show programmes that originated from the BBC I simply gathered it was all down to them...fair dos anyway!
