Black-pine (Pinus nigra) woods grow at altitudes of between 1,500 and 2,000 m., meaning that they can only be found in Navarre in a small area in the far north-east.
They are very loose woods with little underwood, made up of rhododendrons, creeping willow, juniper, etc. Lower woods may mix in with beech, common pine or fir. Bare grass coverage, rocks and rocky outcrops are important components of the landscape.
The birds found in these pine woods consist of forest species and others belonging to more open spaces, due to the significant amount of pastureland which alternates with the tree coverage. The harshness of the environment means that there are not many bird species present and very low densities are found even at breeding time (some 30 birds/10 Ha.).
CThese environments are characterised by the Black Woodpecker, Great Spotted Woodpecker, Ring Ouzel, Dunnock, Black Redstart, Goldcrest, Coal Tit, Marsh Tit, Yellow-billed Chough, Citril Finch, European Serin and Common Chaffinch. The Capercaillie is very rare nowadays. Tengmalm?s Owl is also rare.
