Fuerteventura, the oldest of the Canary Islands, was born approximately 20 million years ago from intense volcanic eruptions. Its formation dates back to the Miocene epoch, a period during which tectonic plates triggered the emergence of underwater volcanoes. These eruptions gradually built a landmass, now known as Fuerteventura, which rises above the Atlantic Ocean.
A Landscape Shaped by Time: Once Majestic Mountains
The mountains of Fuerteventura were once far more imposing than they are today. Initially, some peaks may have reached altitudes of over 3,000 meters, rivaling the high summits of neighboring islands. Over millennia, erosion caused by powerful winds, rare but intense rainfall, and climatic variations gradually wore down these volcanic rock formations.
Today’s mountains, such as the Betancuria range and the Jandía mountains, are mere remnants of these once-impressive landforms. Betancuria, for instance, is modest in height now but represents the oldest geological core of the island. This massive erosion also created the vast plains and plateaus characteristic of Fuerteventura, along with valleys and gorges that bear witness to the ongoing action of natural forces.
In essence, this eroded terrain offers visitors a geological lesson, revealing layers of solidified lava and ancient structures where remnants of Fuerteventura's intense and monumental volcanic past can still be observed.
The Last Eruptions: The Formation of Northern Fuerteventura and Lobos Island
The last major volcanic eruptions on Fuerteventura occurred around 5,000 years ago, drastically transforming the landscape of the island's northern region. Before these events, this part of Fuerteventura and the neighboring Lobos Island did not exist in their current forms. Lava flows and explosive eruptions expanded the land, shaping the volcanic landscapes we see today.
Lobos Island, a small volcanic islet off the coast of Corralejo, is a direct result of this intense geological activity. With its iconic crater, the Caldera Volcano, it stands as a remnant of this recent volcanic epoch. Northern landscapes, home to the Bayuyo and Calderón Hondo volcanoes, also illustrate this late phase of geological formation.
This activity gave rise to fertile lands and impressive geological features, contributing to the unique ecosystem of northern Fuerteventura. Today, these areas serve as symbols of the island’s geological and natural heritage, attracting numerous visitors and researchers eager to explore.
A Unique Canary Ecosystem: The Legacy of Resource Overuse
Despite its resilient ecosystem, Fuerteventura was once far greener and richer in natural resources. Its volcanic soils once supported fertile lands for agriculture and livestock. Over centuries, however, deforestation for firewood, overfarming, and intensive grazing led to the gradual degradation of the environment.
The consequences of this overexploitation have been profound: the loss of vegetation accelerated soil erosion, gradually transforming the island into its current arid landscape. Forests vanished, taking with them soil moisture and contributing to the dry climate. However, local species adapted to these extreme conditions, resulting in a unique biodiversity that includes drought-resistant endemic plants like the Canary spurge and various acacia species.
Today, preservation efforts aim to protect this delicate ecosystem and encourage the growth of native vegetation. Reforestation initiatives and the protection of natural areas, such as the Corralejo Natural Park, strive to restore parts of the environment. This fragile balance between conservation and natural adaptation makes Fuerteventura a powerful example of the impact of human activity on island ecosystems.
The Island Today: Biodiversity Preservation and Protection
Fuerteventura is now an example of balance between environmental preservation and tourism development. Local authorities have implemented significant measures to protect native wildlife and flora, including restricting access to ravines to encourage the nesting of endemic and migratory birds. These areas, crucial for the reproduction of species such as the Cory’s shearwater, are monitored and protected to ensure safe spaces free from human disturbance.
Additionally, Fuerteventura actively participates in reforestation and natural restoration programs. Conservation efforts include environmental awareness campaigns highlighting the importance of natural habitats for the island’s ecosystem. Reserves like the Corralejo Natural Park and other protected areas help maintain the island’s unique biodiversity, which features flora and fauna specially adapted to arid conditions.
These actions reflect the island’s commitment to conservation, enhancing its appeal as an eco-responsible destination respectful of the environment.
Fuerteventura, with its volcanic origins and history of adaptation, embodies the power of nature against the elements and the passage of time. From its ancient geological formation to its unique ecosystems, every aspect of the island tells a fascinating story. Stay tuned for next month’s exploration of the conquest period and how Fuerteventura's early inhabitants shaped its cultural identity—a tale of traditions and resilience not to be missed!
