Mediterranean Forests: Pines, Oaks, and Beeches Define Spain

Can the Mediterranean forest be reduced to a dry pine woodland with rosemary and thyme? This was the thesis that started the debate: the real Mediterranean forest would consist of conifers and aromatic scrub —pine, cypress, cedar, juniper, fir at higher altitudes, and in agricultural lowlands, carob, with date palms on coastal plains— plus an understory of rosemary, thyme, juniper, strawberry tree, and broom. The response came quickly and was not gentle: holm oak, cork oak, and gall oak are also Mediterranean forests, and they have been there much longer than any replanting.

Which trees truly define the Mediterranean forest

The inventory used has three layers. The first is conifers: pine, cypress, cedar, juniper, and fir at high elevations. The second is oaks: holm oak, cork oak, and where water is more abundant, gall oak or Andalusian oak, with scrub in clearings. The third consists of exceptions that break any closed narrative, such as the Spanish fir, a relict fir species that does not live on the coast but in humid mountain ranges.

Some argue that the textbook Mediterranean forest is not made of conifers but of broadleaf trees, noting that Greece itself is full of oak forests. Counter-arguments cite data showing that along much of Spain's Mediterranean coast, oak barely appears except in the Pyrenees, while Aleppo pine dominates the visible landscape. However, this dominance may be recent.

Europe's southernmost beech forest is on the Meseta

The decisive point in the discussion did not come from the conifer side, but from the broadleaf side. The southernmost beech forest in Europe is on the Meseta, not in the Cantabrian Cornice or the Pyrenees, according to those who insistently challenge the narrative of the Castilian plateau. Examples cited include the Montejo beech forest and other similar woods, along with the Tejera Zain beech forest and the oak and juniper forests of Alto Tajo.

The discussion then moves to uncomfortable ground: does it make sense to compare the Cantabrian Mountains or the Pyrenees with the rest of the territory? One observer denies it outright. They are different bioclimatic zones, and measuring the richness of one against the other clarifies nothing. What is shared are the names: beeches, birches, chestnuts, oaks, and Scots pine appear in Meseta mountains with sufficient altitude and humidity.

Aleppo Pine: Planted, Non-native, and Fire-adapted

One of the points where the exchange becomes harsher is fire. Some claim that Aleppo pine is a non-native, planted species, and that it is also pyrophytic: it burns easily and regenerates just as easily. From there to blaming half a century of replanting for Valencia's fire map is a stretch, but the argument is used to dismantle the label of authentic forest given to pine stands.

Documentary evidence supports this suspicion of youth. In inland Valencia, place names preserve terms like Camino de los Carboneros, Cueva de los Latoneros, Partida del Fresnal, or Barranco del Tejar, which point to holm oaks, hackberries, yews, and ashes where today only brush or pines remain. And of those pines, according to the same count, none are older than 80 or 90 years that have escaped one or more fires since the seventies.

Juniperus Sabina Thrives Between 200 and 2,000 Meters

Against the idea that the Mediterranean tree is merely a plant for extreme conditions, Juniperus sabina appears as an inconvenient counterexample. It can be found at 200 meters and 2,000 meters above sea level, on limestone and acidic soil, with 300 and 700 millimeters of annual rainfall. The conclusion drawn is simple: many species endure more than the narrative allows; what they need is time.

The problem is that time is exactly what is lacking. Where place names promise oak forests, fire and replanting have left young pine stands. Where pine forests burn, pine forests return. The result is that comparisons between landscapes are always made on forest material that has been intervened, burned, or replanted several times in less than a century.

Where is the Humid Forest in Spain?

The Grazalema and Sierra de las Nieves ranges serve in the exchange as proof that the south also holds Atlantic-regime forests. There lives the Spanish fir, and there annual rainfall exceeds 2,000 millimeters, figures that confuse those who associate Andalusia with dryness. At the other extreme, the Filabres and Gádor ranges in Almería receive a blunt diagnosis: little forest.

Between these extremes lies the aesthetic argument, which weighs as much as the botanical one in this discussion. Pine and cypress smell, oak forests smell of old wood, and walking under a canopy of branches touching in the middle of the path changes the mood, as defended by a mix of physiology and nostalgia. No one has measured this, but the emotional record ends up deciding more positions than any forest inventory.

With the data on the table, the dispute remains open: each side can point to a mountain range that proves them right. Aleppo pine will continue growing where allowed, holm oak will continue waiting its turn underground, and the Meseta beech forest will remain the unexpected guest at the party.
