Photographer’s Note

The photo shows the forest house of Los Tilos in the island of La Palma. Although the photo was taken on an otherwise sunny day, the house is covered by moist and mold.
The North-Eastern side of La Palma is covered by Laurel forests, a vegetation unique to the Canary Islands and Madeira. The North-Eastern winds condensing against the slopes of the island create a very humid environment with a very special fauna and flora.

The vegetation of the mountain and humid areas of the Canary Islands consists of luxurious groups of evergreen trees with laurel-like leaves which, in Spanish, are called by the characteristic name of "monte verde" or "laurisilva canariense". The trade winds blowing from north-west determine a constant supply of humid air masses which, climbing up the slopes of the mountains, tend to condense creating a dense fog, the thickness of which depends on the season. This fog belt, practically present all the year, is the most important cause of the development on the slopes facing north or north-west, of the optimum microclimate conditions for the expansion of forests dominated by evergreen wooden species of sub-tropical origin. The developing potential area of "monte verde" is included in the strip between 500 and 1,600 meters high, on the north-west slopes in the western islands, and in some conditions (which can be found in the Anaga massif in Tenerife) the lowest limit can go as down as 100 metres above sea level.

The trees with laurel-like leaves in the Canary Islands must be regarded as a sort of living Paleo-flora, relict of a kind of sub-tropical humid vegetation which, until the end of the Tertiary period (late Miocene and early Pliocene), could be found in large parts of South Europe and North Africa.
