Crisp autumnal walks, windy moors, muddy boots and sinking into a comfy armchair by a warm pub fire; these are the quintessential experiences of Britain’s stunning National Parks.

But what many people might not think of is the staggering biodiversity and conservation efforts occurring in these parks, and the year-round efforts of hard-working scientists, agriculturists, and volunteers to ensure a bright future for the flora and fauna of the British Isles.

Featuring creatures great and small, including puffins, eagles, snakes, squirrels, elk, seals, goats, sheep and even wild horses, this breath-takingly cinematic series travels across the windswept landscapes of Northumberland, New Forest, Dartmoor and the Pembrokeshire Coast to reveal the untold side of Great Britain’s wild kingdom.
