SIR David Attenborough’s Secret Garden is reportedly set to return for a second series after its first run put the wildlife and environmental challenges of the Wye Valley in front of millions of viewers.

The BBC natural history programme, narrated by Sir David, explored the often-hidden lives of animals found in gardens and landscapes across Britain, with the Wye Valley taking centre stage in one of five episodes.

According to Broadcast, the BBC has recommissioned the programme following the success of its first series, which attracted an average audience of 4.7 million viewers.

Broadcast on May 3, The Wye Valley followed Robin, Laura and their sons at their home hidden in a steep Welsh valley and surrounded by one of Britain’s most biodiverse woodlands.

Its unusual location meant the garden was particularly affected by the changing seasons, with winter sunlight failing to reach it for months.

Cameras captured dormice, tawny owls, badgers, bumblebees and migratory flycatchers, while a dipper was filmed hunting aquatic insects in the stream running beneath the house to feed its chicks.

The episode also highlighted environmental pressures facing wildlife in the Wye catchment, with poor water quality leaving the dipper family struggling to find enough food.

Robin stepped in with mealworms to help the chicks survive.

Other dramatic moments included a badger mother bringing her cubs above ground and tawny owl chicks competing for food, with a smaller owlet eventually pushing its larger sibling from their nest.

The series was released around Sir David’s 100th birthday on May 8 and was co-produced by Plimsoll Productions alongside The Open University.

Producer Bill Markham said Sir David’s involvement had a “profound effect” on the production.

Full details of the reported second series, including locations and whether the Wye Valley could feature again, have yet to be officially announced.
