Common-pine (Pinus sylvestris), also known as Scots Pine or Red Pine, woods occupy the extreme north-east of Navarre. They are well distributed throughout most of the Pre-Pyrenees and lower parts of the Pyrenees. These woods are believed in the past to have been confined to rocky, abrupt spots, human interference favouring a more opportunist character and leading to the colonisation of larger areas.
There are now fairly extensive woods, mainly on mountainsides. Many of these pine woods are felled for timber.
Maple, oak, lime, beech and service trees are interspersed between the common pines in these woods and there is thick underwood in the form of box and hawthorn.Birds:
The range of wild birds found in these woods is varied and often exceeds densities of 100 birds/10 Ha. The autumn pine kernels attract numerous wintering species.
The bird species which characterise these pine woods are the Common Woodpigeon, Common Cuckoo, Wren, Robin, Dunnock, Song Thrush, Mistle Thrush, Blackbird, Blackcap, Bonelli?s Warbler, Iberian Chiffchaff, Redcrest, Short-toed Treecreeper, Great Tit, Coal Tit, Blue Tit, Crested Tit, Eurasian Jay, Common Chaffinch, Citril Finch and Common Crossbill. The Yellowhammer, Cirl Bunting and Rock Bunting can appear in cleared pine woods.
Birds of prey are represented by the Sparrowhawk, Goshawk and Common Buzzard, and nocturnal species by the Long-eared Owl.
