The television series culminated in a live fundraising telethon on BBC Two, hosted by Alan Titchmarsh, which raised over £1 million for the charity.

The BBC broadcast a second live telethon in 2010. Wild Night In was presented by Kate Humble, Chris Packham and Martin Hughes-Games and featured conservation projects which had benefited from the support of the BBC Wildlife Fund. This helped to raise a further £1 million.
