Semi-wild horses at Knepp Estate, UK and wider derogations

Although English law already contains mechanisms that allow semi-wild horses to benefit from reduced horse passport and microchipping requirements, these rules remain complex, difficult to navigate and largely inaccessible for most rewilding projects.

Collaborating with Knepp and Defra, we’re aiming to create clearer legal pathways for registering semi-wild herds, and developing practical models that can be replicated by other projects to better support semi-wild horses as ecosystem engineers for nature recovery.

Leaving large herbivore carcasses in the ecosystem

Animal carcasses are an important part of functioning ecosystems. When left where they fall, they recycle nutrients, support insects and soil communities, provide a source of minerals for plants, and provide vital food sources for scavenger species.

Large herbivores used in rewilding projects, including cattle and horses acting as ecological proxies, can play an important role in restoring these natural processes. Yet unlike wild animals such as deer, they’re generally subject to strict rules requiring carcass removal and incineration. This creates practical challenges for rewilding projects and prevents carcasses from fulfilling their ecological role.

Through our Rewilding Legal Innovation Lab, we’re exploring how legal frameworks governing animal by-products, livestock carcass disposal and nature recovery could evolve to better support ecological restoration. Across the UK and Europe, we’re researching innovative legal pathways that could allow large herbivore carcasses to remain in the landscape safely and appropriately as part of functioning ecosystems.

Creating legal pathways for wild and semi-wild large herbivores

Working with Rewilding Spain and Rewilding Europe, we’re exploring how existing legal frameworks can better support large herbivores living in wild and semi-wild conditions within designated rewilding landscapes.

Our work focuses on horses, Tauros cattle and European bison in Castilla-La Mancha, where we are testing practical legal approaches to reduce the impact of livestock regulations designed for conventional farming systems and enable animals to live more naturally. This includes the use of a núcleo zoológico conservation centre status for bison.

This project is helping to develop practical legal models for rewilding with large herbivores and demonstrating how regulatory systems can evolve to better support nature recovery.

Additionally, we are exploring this topic in the UK where we are engaging with the Commission about a possible new “kept-wild” category. Get in touch if you’d like to see the full report.

We are also part of a wider European project in which we lead the legal analysis of rewilding with large herbivores across six jurisdictions: Portugal, France, the Netherlands, Denmark, Spain, and Croatia. The project maps what the current law allows, where derogations can help, and explores the case for legal change, including a possible new “kept-wild” category. Results to be published in due course.
