Iberian Wolf (Canis lupus signatus)

Iberian Wolf (Canis lupus signatus) – (Cabrera 1907)

Common Names:  Iberian Wolf,  Lobo Iberico

Overall population: 2003 census (2,000), 2005 (approx. 2000)

Physical description: Signatus is Latin for “marked”  describing the characteristic white marks on the lips and and darkened/black markings on the legs, back and tail. The Iberian Wolf has a smaller frame than the Eurasion Wolf. Males are larger and are said to weigh up to 110lbs (50kg) and females 66lbs-88lbs (30kg-40kg).

Range:
Original range – Iberian Peninsula
Current range – Forest and plains of northern Portugal and northernwestern Spain.

Habitat / Ecology / Prey:
Habitat

PreyWild Boar (Sus scrofa), Roe Deer (Capreolus capreolus), Red Deer (Cervus elaphus), Iberian ibex (Capra pyrenaica), European rabbit (Oryctolagus cuniculus), Granada hares (Lepus granatensis), Cantabrian chamois (Rupicapra pyrenaica parva), feral horses, domestic goats

“Scat analysis indicated a high predation on wild ungulates, where the frequency of occurrence showed that roe deer was the most consumed prey (44%), followed by red deer (26%) and wild boar (24%). Domestic/wild cat (6%), domestic goat and stone marten (5%) were consumed in lower quantities.”

“Domestic goat predominated the diet (62% of the scats), followed by cow (20%) and sheep (13%); the only wild ungulate present in the scat analysis was the wild boar (4% of the scats).”

Legal and Cultural Background:
Legal status – The hunting of wolves is prohibited in Portugal but allowed in certain areas of Spain.
