David Attenborough’s voice returns to British screens in ‘Secret Garden’, a BBC One series launched to celebrate the network’s 100th birthday. Unlike his classic wildlife documentaries, the show turns the lens toward the UK’s own backyards, exploring how gardens can rival tropical rainforests in biodiversity.Series producer Bill Markham explains that the programme deliberately avoids the usual “lions and tigers” spectacle, aiming instead for a relatable, garden‑centred narrative. He notes that British gardens collectively cover more area than all national nature reserves combined, and that an average garden can host up to 2,600 different species.The series tackles the contentious issue of domestic cats. With 9.5 million pet cats in Britain, Attenborough reveals they may kill around 55 million birds each year. Simple measures—such as fitting cats with bells—can slash hunting success by one‑third, while raising bird feeders reduces fatalities further.Markham stresses that the current predator‑prey balance is “unfair on the prey”, noting that cats are “the biggest predator in our gardens” yet are constantly fed, leading to an unsustainable population. He cites ecologist Dr Davide Dominoni, who suggests that keeping cats indoors during the breeding months of April and May could dramatically lower bird deaths.Beyond cats, the series examines other garden‑linked wildlife challenges. Each year, over 30 million pheasants—an Asian species—are released into the countryside, where they prey on native insects, reptiles, and amphibians. Markham argues that despite the countryside lobby’s claim that pheasant shooting sustains rural jobs, the practice “mess‑es with the ecology”.‘Secret Garden’ also showcases rare footage, including a pine marten hunting sand martins, an otter preying on ducks, and intricate mayfly battles reminiscent of the famed “snakes vs. iguana” scene from Planet Earth II. These moments underline the hidden drama unfolding in everyday green spaces.Markham hopes the series will soothe the growing eco‑anxiety many feel about climate change. He points out that the UK boasts roughly 25 million gardens, with 80 % of the population having access. Simple actions—like planting a native tree to boost caterpillar supplies for birds—can make a measurable difference.While the show may provoke cat owners and countryside advocates, Markham believes the nation’s love for “animals, gardens and David Attenborough” will drive a collective re‑thinking of garden stewardship. As Attenborough reflects, his first encounter with nature likely occurred in his own garden, setting him on the path to becoming the world’s most renowned naturalist.‘Secret Garden’ airs from 5 April on BBC One and iPlayer.

The barnacle geese of Norfolk continue to fascinate and surprise. What was once a rare winter sight, with only a few individuals from the Siberian population visiting, has turned into a spectacle with 700 birds now calling Holkham Park home. Their presence is a testament to their adaptability and the changing climate.The author's fond history with these geese dates back to 2021 when they helped ring 400 of the birds as part of an ornithologist's study. The process involved herding the flightless, moulting flock onto a lake and guiding them into a corral. Each bird received a numbered Darvic ring, allowing for monitoring in the wild.The geese's journey to their wintering grounds is remarkable. After leaving Holkham in August, they flew 70 miles to Southwold, where they joined a breeding flock from Pensthorpe. This flock consists of descendants from deliberate releases in the 1980s.The author expresses a deep affection for these birds, admiring their chalk-faced, velvet-hooded appearance and their quiet defiance in the face of their transplanted ancestry. From the Arctic tundra to Norfolk, they have made a new home, demonstrating their resilience and adaptability.The presence of barnacle geese in Norfolk is not just a local phenomenon but also a reflection of broader environmental changes. Their story serves as a reminder of the complex relationships between species, climate, and human activity.
