Horse breed
Horse breed is a broad term with no clear consensus as to definition, but most commonly refers to selectively bred populations of domesticated horses, often with pedigrees recorded in a breed registry. However, the term is sometimes used in a very broad sense to define landrace animals, or...

. Studies are currently ongoing to discover the relationship between the Sorraia and various wild horse types, as well as its relationship with other breeds from the Iberian Peninsula and Northern Africa.

Members of the breed are small, but hardy and well-adapted to harsh conditions. They were occasionally captured and used by native farmers for centuries, and a remnant population of these nearly extinct horses was discovered by a Portuguese zoologist in the early 20th century. Today, the Sorraia has become the focus of preservation efforts, with European scientists leading the way and enthusiasts from several countries forming projects and establishing herds to assist in the re-establishment of this breed from its current endangered status.

Characteristics

The Sorraia breed stands between 14.1 and 14.3 hands high (57 to 59 in (144.8 to 149.9 cm)), although some individuals are as small as 12.3 hands high (51 inches (130 cm)). The head tends to be large, the profile convex, and the ears long. The neck is slender and long, the withers

Evolution and taxonomy

The relationship between the Sorraia and other breeds remains largely undetermined, as is its relationship to the wild horse
Wild Horse
The wild horse is a species of the genus Equus, which includes as subspecies the domesticated horse as well as the undomesticated Tarpan and Przewalski's Horse. The Tarpan became extinct in the 19th century, and Przewalski's Horse was saved from the brink of extinction and reintroduced...

 based on shared morphological features, principally the typical color of its coat. Other authors simply state that the Sorraia has "evident primitive characteristics", although they do not refer to a specific ancestor. However, there have been no genetic studies comparing the Sorraia with the Tarpan, and similarity of external morphology is an unreliable measure of relatedness.

Genetic studies to date have been inconclusive about the closest relative of the Sorraia. On one hand, studies using mitochondrial DNA showed a relationship with the Przewalski's Horse

 from one of the major Sorraia haplotypes (JSO41, later A7). In comparison, genetic distances within the domestic horse are as large as 11 nucleotide differences. However, this relationship with the Przewalski's Horse was contradicted in another study using microsatellite data that showed that the genetic distance between the Prewalski's Horse and the Sorraia was the largest. Such conflicting results can arise when a population passes through a genetic bottleneck, and evidence suggests that the Sorraia, among other rare breeds, has recently passed through a bottleneck, effectively obscuring the position of this breed in the family tree of the domestic horse. Thus, the morphological

, physiological, and cultural characteristics of the Sorraia are the subject of continued study to better understand the relationship between various Iberian horse breeds and wild horse subspecies.

s, some of whom closely resembled the modern-day Sorraia, to the Americas in their conquests, probably as pack animals. Similarities between the Sorraia and several North and South American breeds are shown in the dun and grullo coloring and various physical characteristics. This evidence suggests that the Sorraia, their ancestors, or other horses with similar features, may have had a long history in the Iberian region and a role in the creation of American breeds.

Otherwise, the Sorraia breed was lost to history until 1920, when Portuguese zoologist and paleontologist Dr. Ruy d'Andrade first encountered the Sorraia horse during a hunting trip in the Portuguese lowlands. This remnant herd of primitive horses had continued to live a wild existence in these lowlands, which were rather inaccessible and had been used as a hunting preserve by Portuguese royalty until the early 1900s. At the time of d'Andrade's initial meeting the breed, the horses were ill-regarded by native farmers, although they were considered hardy native fauna that lived off of the uncultivated lands and salt marshes in the local river valleys. For centuries, peasant farmers of the area would occasionally capture the horses and use them for agricultural work, including threshing

s from horses obtained near Coruche, Portugal. All Sorraias currently in captivity descend from these original horses obtained by d'Andrade, and it is believed that the remnant wild herds of the breed died out soon after. These horses were kept in a habitat similar to their native one.
In 1975, two other farms took up the Sorraia's cause and acquired small herds to help with conservation. In 1976, three stallions and three mares were imported to Germany from Portugal to begin a sub-population there. In March 2004, a small breeding herd of Sorraia horses was released on the estate of a private land owner who dedicated a portion of his property so that these horses could live completely wild, as did their ancestors. The refuge created for them is in the Vale de Zebro region of south western Portugal, one of places so named because this is where the Sorraia's predecessors dwelt.

Two Sorraia stallions were imported to the United States in the early 21st century. In 2006, another Sorraia stallion was imported to Canada where a Sorraia Mustang Preserve has been established on Manitoulin Island
