. 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

Characteristics

The Sorraia breed stands between 14.1 and 14.3 

croup slightly sloping. The legs are strong, with long pasterns and well-proportioned hooves. These horses have good endurance and are easy keepers, thriving on relatively little fodder. They have a reputation for being independent of temperament, but tractable.[3]

On adult horses, the lay of the hair can create the appearance of stars and flags on the neck and chest. Also due to the lay of the hair, newborn foals can appear to have stripes all over, reminiscent of zebra stripes. The breed standard refers to this as "hair stroke".[4]

Color

Sorraia are generally

pangare genetics.[6] Sorraia horses have bi-colored manes and tails with lighter colored hairs that fringe the outside of the longer growing black hair.[4] This is a characteristic shared with other predominantly dun-colored breeds, such as the Fjord horse.[7] Purebred Sorraia occasionally have white markings, although they are rare and undesired by the breed's studbook.[4]

Genetics

The relationship between the Sorraia and other

Asturcon,[10] but genetic studies using mitochondrial DNA show that the Sorraia forms a cluster that is largely separated from most Iberian breeds.[11][12][13][14] Some evidence links this cluster with Konik and domestic Mongolian horses.[12] At the same time, one of the maternal lineages is shared with the Lusitano.[15] Genetic evidence[11] has not supported a hypothesis that the Sorraia is related to the Barb horse, an African breed introduced to Iberia by the Moors.[16]

Multiple authors have suggested that the Sorraia might be a descendant of the Tarpan based on shared morphological features, principally the typical color of its coat.[2][3][17] Other authors simply state that the Sorraia has "evident primitive characteristics", although they do not refer to a specific ancestor.[5] However, there have been no genetic studies comparing the Sorraia with the Tarpan, and similarity of external morphology is an unreliable measure of relatedness.[11]

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

History

Although it is known that the Sorraia developed in the southern part of the Iberian peninsula,

Mustangs in the western United States that show similar mtDNA patterns between some Mustangs and the Sorraia breed.[16] Spanish conquistadors took Iberian horses, some of whom closely resembled the modern-day Sorraia, to the Americas in their conquests,[16] probably as pack animals.[2] 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.[16]

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.

agricultural work, including threshing grain and herding bulls.[22]

In the 1920s and 1930s, as mechanization became more prevalent, both wild and domesticated breeding stock diminished to almost nothing, and d'Andrade, along with his son Fernando, encouraged the conservation of the breed.[17] In 1937, d'Andrade began a small herd of his own with five stallions and seven mares 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.[12][23] These horses were kept in a habitat similar to their native one.[17] 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.[5] 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.[24] Today, the breed is nearly extinct, with fewer than 200 horses existing as of 2007, including around 80 breeding mares. The Food and Agriculture Organization considers it to be maintaining critical risk status. The first studbook was published in 2004, dedicated to maintaining a written record of the bloodlines of the Sorraia.[23] Sorraias are present mainly in Portugal,[11] with a small population in Germany.[2] While not bred for a specific use, the Sorraia horses are versatile and have been used in herding bulls, dressage riding and light harness.[24]

American preservation efforts

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

mtDNA testing show a genetic relationship with the Sorraia and are breeding them according to both genotype and phenotype in an attempt to help preserve what they are calling the "American Sorraia Mustang".[25]

Naming

Dr. Ruy d'Andrade gave the breed their name of "Sorraia".[21] D'Andrade took the name from the Sorraia River in Portugal.[3] The breed had previously been known by the local Portuguese as "zebro" or "zebra", due to their markings.[24] In the time of Christopher Columbus, the Sorraia was also known as the Marismeño,[26] but the Sorraia and the Marismeño have evolved into two different breeds over time. Today, the name Marismeño refers to a population of semiferal horses living in Doñana Natural Park in Spain.[11]
