Campaigners warn that new biodiversity restrictions in Dartmoor National Park could lead to a large-scale cull of endangered hill ponies.

The dispute highlights a growing conflict between strict environmental conservation targets and the preservation of heritage livestock breeds. Because the ponies are considered endangered, any significant reduction in their population could threaten the long-term viability of the breed.

Natural England has introduced new conservation rules requiring reduced livestock grazing to protect biodiversity in the region. Campaigners said these restrictions could force a massive cull to meet the new grazing limits.

There are approximately 1,000 endangered Dartmoor ponies currently in the park [1]. According to different reports, the potential cull could affect between 90% [2] and 93% [3] of the pony population.

The row has centered on how to balance the recovery of native flora and fauna with the presence of the ponies. While the government and certain campaigners have rejected rumors of an official cull, the mathematical reality of the grazing limits remains a point of contention.

Critics of the plan said that reducing the number of grazers so drastically would be counterproductive to the ecosystem. They argue that the ponies play a vital role in maintaining the moorland habitat, and removing the vast majority of the herd would damage the very biodiversity the rules intend to protect.

Local advocates continue to call for a revised approach that integrates the endangered ponies into the biodiversity strategy, rather than treating them as a liability to be reduced.

The potential cull could affect between 90% and 93% of the pony population.

This conflict illustrates the 'biodiversity paradox' where efforts to restore wild ecosystems can clash with the preservation of rare, domestic-wild hybrid breeds. If the grazing limits are strictly enforced without alternative management strategies, the Dartmoor pony could face a genetic bottleneck, potentially leading to the extinction of the breed in its native habitat.
