Why Forests Are Scarce in the Eastern Mediterranean: Climate & Human Legacy

The eastern Mediterranean (Levant, Anatolia, Aegean, Cyprus, Sinai) is naturally forest-poor due to a brutal climate filter—amplified by 10,000 years of human pressure.

1. Climate: The Mediterranean Filter

• Köppen Csa: Hot, dry summers (May–Oct: ~0 rain); mild, wet winters.
• Water deficit: Potential evapotranspiration > precipitation 6–8 months/year.
• Soil moisture: Deep summer drought kills seedlings; only deep-rooted perennials survive.
• Fire regime: Natural lightning fires + dry fuels = frequent burns; selects for fire-adapted species.

2. Native Woody Vegetation (Not "Forest" in Temperate Sense)

• Sclerophyllous shrublands: Maquis (evergreen shrubs: kermes oak, strawberry tree, pistacia, myrtle).
• Garrigue/Phrygana: Low, spiny, aromatic shrubs (thyme, sage, genista) on degraded soils.
• Woodlands (not closed forests): Aleppo pine, Brutian pine, Holm oak, Kermes oak—open canopy, 20–40% cover.
• Relict forests: Cedar of Lebanon, Cilician fir, Oriental beech—only in high, wet microclimates (>1,000 m).

3. Human Impacts (Millennial Scale)

4. Modern Threats

• Climate change: +1.5°C already; models project +3–4°C by 2100 → further aridification.
• Desertification: 30% of region at high risk (UNCCD).
• Invasive species: Acacia, Eucalyptus, Ailanthus outcompete natives.

Conservation Bright Spots

• Protected areas: Samaria Gorge (Crete), Köprülü Canyon (Turkey), Al Shouf Cedar (Lebanon).
• Restoration: Assisted natural regeneration, seed banks, grazing exclusion.
• Traditional knowledge: Reviving hima (community conserved areas) in Levant.

The eastern Mediterranean isn’t "deforested"—it’s a cultural landscape where climate and humanity co-evolved a resilient, open, shrubby mosaic. True closed forests are relics, not the norm.
