We urgently need your support to ensure food for the wild horses of the Pottokas Project in Piornal, Spain. Their usual grazing area has been reduced in recent months due to forest replanting work. With this campaign, we aim to raise €25,000 to purchase materials and fence an additional 25 hectares of land, ensuring that the wild horses in Piornal have access to pasture during the coldest and rainiest months of the year.

Expanding the grazing area is a top and urgent priority to guarantee that the horses have enough food and to support their physical, mental, and emotional wellbeing. Your support will also benefit domestic horses through this pioneering European project.

Pottokas Project in Piornal

Pottokas in Piornal is a research and rewilding project involving wild horses. Based on scientific evidence, it allows a deeper understanding of the needs of the species as a whole, improving the wellbeing of those living in captivity (in sport, leisure, or farming contexts) and demonstrating the positive effects of rewilding territories with large herbivores.

Horses have three essential needs: food, companionship, and freedom. Domestic horses typically live in conditions far removed from those for which evolution has prepared them: stabled indoors, with limited direct contact with other horses, and subjected to exercises contrary to their natural behaviour. They do their best to adapt, but often experience physical and emotional health issues that affect their relationship with people.

Behavioural disorders are important indicators of poor animal welfare. Only by studying the natural behaviour of wild horses can we identify what is abnormal in domestic horses and improve their wellbeing.

Social Structure of Horses

Currently, after more than 15 years of the project, around 40 horses live in Peña Negra, organised into several bands and well adapted to the environment. These bands or family groups consist of one stallion, one or more mares, and their youngest offspring. These are groups formed freely by the horses themselves, with strong social bonds among members.

They watch over and protect each other from potential predators, move and rest in synchrony, and spend much of their time walking and grazing across the territory, covering around 15 kilometres per day. Evidence also shows that these bands do not display hierarchies or dominance: cooperation and mutual care prevail. They live in harmony and peace with the beings around them.

Rewilding and Ecosystem Services

Over recent years, it has also been observed that through their natural activity, the pottokas are improving local fauna and flora biodiversity and providing important ecosystem services—especially regulatory, supporting, and cultural services. It is also worth highlighting the growing bond between local residents and the horses, which is contributing to a shared identity around them and strengthening Piornal’s cultural landscape.

La Asociación Caballos Salvajes Lucy Rees nace con la misión de mejorar la vida de los caballos y fortalecer la relación entre personas y caballos. Para ello impulsa y sostiene el Proyecto Pottokas en Piornal (Cáceres).

Lucy Rees es una de las máximas expertas en etología equina a nivel mundial. Cuenta con una larga trayectoria de observación de caballos en libertad en todo el mundo y de investigación sobre su comportamiento social.

En 2011, Lucy Rees pone en marcha el proyecto de investigación con caballos pottokas en el monte de Peña Negra de la Sierra de Tormantos, en colaboración con el Ayuntamiento de Piornal y la Junta de Extremadura. Con el proyecto, los pottokas viven en libertad sin intervención humana en un territorio de unas 800 hectáreas de entre 700 y 1500 metros de altitud, dentro de la Zona de Especial Conservación (ZEC) de Sierra de Gredos y Valle del Jerte, que pertenece a la Red Natura 2000 de la Unión Europea.

La raza pottoka es una raza equina ancestral, autóctona de la Península Ibérica, actualmente en peligro de extinción e introducida por Lucy Rees en Piornal a partir de ejemplares del País Vasco. Entender la naturaleza y formas de relación de los caballos silvestres permite mejorar el bienestar del caballo doméstico, prevenir y abordar problemas de salud mental y física y ayudar a las personas a comprender y comunicarse mejor con los caballos.

Además, el proyecto está demostrando que la renaturalización del territorio con caballos silvestres genera impactos ambientales positivos en la biodiversidad y prevención del cambio climático, como son la oxigenación y fertilización del suelo, la fijación del CO2 y de la humedad, la generación y protección del bioma del suelo (hongos y bacterias) y una mayor biodiversidad, especialmente de invertebrados, polinizadores y aves.

Este proyecto, pionero en Europa, está permitiendo conocer en profundidad los comportamientos sociales de los caballos y aportar herramientas viables basadas en la naturaleza para una mejor gestión del territorio. El conocimiento generado se está transfiriendo a la sociedad a través de libros, artículos, documentales y series audiovisuales divulgativos, así como con material científico para universidades nacionales e internacionales. La asociación también colabora con la iniciativa de la Unión Europea EHorse y Life Watch ERIC, en la publicación de evidencias científicas del proyecto y con Rewilding Spain en proyectos de renaturalización con caballos en España aportando pottokas nacidos en libertad.

En 2025 Lucy Rees recibió el Premio a la Renaturalización de Especies -Species Rewilding Award- de la organización internacional Rewilding Academy
