Lepus granatensisGranada hare

Geographic Range

Iberian hares (Lepus granatensis) are found on the Iberian Peninsula, which is located in southwest Europe and includes Andorra, Portugal and Spain. This region is commonly referred to as simply Iberia. Iberian hares are common throughout the peninsula, except in the far northeast, where their range meets that of brown hares. Iberian hares are also absent from some pockets in the Cantabrian Mountains, which are dominated by broom hares. Together, brown hares and Iberian hares are western Europe’s most common hares and are important game species. In northeast Spain, the range of Iberian hares joins the range of brown hares. Iberian hares tend to be more prevalent in their own range than in the transition zone between the two ranges. The Iberian Peninsula was highly affected by glaciation during the Pleistocene, causing species to fragment. Iberian hares are no exception, this is believed to be what caused the species to diversify from others in the region. The range of Iberian hares may have expanded during warm periods, causing the ranges of mountain hares and others to shrink. (Alves, et al., 2000; Alves, et al., 2002; Gortazar, et al., 2007; Melo-Ferreira, et al., 2005)

Habitat

Iberian hares are most common in the northern Iberian Mountains. Much of this area has a less extreme climate than other parts of the peninsula, such as the Ebro Depression and the southern Iberian Mountains, suggesting that Iberian hares prefer moderate climates. The species tends to prefer the agricultural ecosystems common to this region. Though Iberian hares can be found in the southern Iberian Mountains and Ebro Depression, abundances in these areas are not as high, possibly due to the extremely low rainfall, harsh winters and lack of agricultural ecosystems. Iberian hares may occupy a variety of landscape types within their range including forests, shrublands and grasslands. (Gortazar, et al., 2007; Smith and Johnston, 2008a)

Physical Description

Iberian hares are similar in appearance to hares found in North America and Europe. Like other hares, Iberian hares are notable for their disproportionately long ears, which are about 100 mm in length. Their coat is generally different shades of brown, brownish-red or gray, while their ventral side is white. As with other hare species, both males and females are about the same size, with total lengths of about 600 to 750 mm. These hares do not exhibit any notable sexual dimorphism. Their face and snout are short and wide. (Bansfield, 1974; Hall and Kelson, 1959)

  • Sexual Dimorphism
  • sexes alike
  • Range length
    600 to 750 mm
    23.62 to 29.53 in

Reproduction

No information could be found specifically regarding the mating systems of Iberian hare. Most leporids exhibit polygynandrous sexual behavior, meaning both males and females copulate with multiple partners. (Feldhamer, et al., 2003)

Courtship and mating occur during the spring season; hares leap in the air and perform twists during the courting process. This is one of the few times individuals interact with conspecifics. Their newborns, known as “leverets”, are born with full pelage and open eyes. There are generally less than five leverets per litter; however, a single female may produce up to seven litters per year. Unlike rabbits, they do not dig full burrows but create a shallow depression in the ground called a “form”, in which to give birth. ("Hare", 1994; "Hare", 2004; Van Den Brink, 1968)

  • Breeding interval
    Iberian hares breed multiple times during the mating season.
  • Breeding season
    Their mating occurs during the spring.
  • Range number of offspring
    1 to 5

There is currently no information available regarding the parental investment of Iberian hares.

Lifespan/Longevity

Like most hares, the life expectancy of Iberian hares is low. The closely-related and overlapping species, European hares, have a life expectancy of just 1.04 years. Information pertaining specifically to Iberian hares is not available, but they are likely similar to European hares. (Smith and Johnston, 2008b)

  • Average lifespan
    Status: wild
    1.04 years

Behavior

Iberian hares make forms in the ground for resting and raising young. These forms are made by scratching a depression into the soil. Hares lie in the form with their lumbar region facing outward, forms become larger with increased use. Forms are usually found in sheltered areas, such as under brush and logs. This species is nocturnal, however, activity periods can vary and Iberian hares are commonly seen during daylight hours. They are solitary animals, except when mating and raising young. (Van Den Brink, 1968)

Home Range

No information is available regarding the home range size of Iberian hares.

Communication and Perception

Like other hares of the world, Iberian hares are mostly quiet under normal conditions. However, when in extreme distress, hares may emit a high-pitched screech or scream-like call. Hares also sometimes stomp the ground violently with their hind legs in order to warn others of danger. ("Hare", 2004)

Food Habits

Like all hare species, Iberian hares are herbivores, feeding on plant material. They are commonly found in agricultural regions where they feed on crops and in vineyards. In forested areas, hares feed on buds, twigs and bark, especially in winter. (Bansfield, 1974; Van Den Brink, 1968)

  • Plant Foods
  • leaves
  • wood, bark, or stems
  • flowers

Predation

Little is written on predation of Iberian hares, but predators of other hare species worldwide are likely similar. Common hare predators include dogs such as coyotes, foxes and wolves, as well as wild and domestic felines. Predatory birds such as hawks and eagles are also a threat. (Bansfield, 1974)

  • Anti-predator Adaptations
  • cryptic

Ecosystem Roles

The intestinal coccidian, Taenia pisiformis cysticercus, has been found using Iberian hares as hosts. These parasites may decrease hares' survivability when attempting to escape predators. (Alzaga, et al., 2008)

Commensal/Parasitic Species
  • Taenia pisiformis cysticercus

Economic Importance for Humans: Positive

Iberian hares are a very common and important game species in Europe. (Alves, et al., 2002)

  • Positive Impacts
  • food

Economic Importance for Humans: Negative

Iberian hares tend to frequent agricultural habitats and may cause some crop damage, especially where their populations are high. (Gortazar, et al., 2007)

  • Negative Impacts
  • crop pest

Conservation Status

Iberian hares are listed as a “Least Concern” species by IUCN Redlist; however the species is believed to be extinct on the island of Mallorca and around Galacia and Asturias, although their numbers have been trending upward in many other areas. (Smith and Johnston, 2008b)
