Italy's Apennines: Bears and Hidden History

The Apennine mountains run along the centre of Italy, featuring high peaks that merge into woodland, lakes, and pasture [1]. This rugged terrain serves as a habitat for a critically endangered subspecies of brown bear and conceals ancient archaeological sites that have remained hidden for centuries [1, 2].

Key takeaways

• The Marsican brown bear population in the Apennines is estimated at around 51 individuals, making it the most endangered of the 14 brown bear subspecies [1].
• Archaeologists using drones in the Molise region discovered that ancient settlements in the Apennines were denser and more organized than previously thought [2].
• The Marsican bear has evolved a distinctive jaw structure within the last 600 years, likely due to isolation from other bear populations [1].

A sanctuary for the Marsican bear

The Apennines are home to the Marsican brown bear, a subspecies that has survived in isolation for thousands of years [1]. With a current population estimate of around 51, these bears are considered the most endangered brown bear subspecies in the world [1]. Researchers have noted that the Marsican bear possesses a unique mandible, or lower jaw, which is thick below the teeth to help crunch nuts [1]. Genetic estimates suggest this distinctive trait developed relatively recently, within the past 600 years, after human habitat changes cut the population off from the wider European brown bear gene pool [1]. While the brown bear species as a whole is classified as "Least Concern," this specific group remains completely isolated from neighbors in the Italian Alps [1].

Uncovering ancient civilizations with drones

In the southern region of Molise, the rugged landscape of the Apennines has long concealed archaeological sites from standard discovery methods [2]. Researchers using small commercial drones to survey the area of Le Pianelle in the Tappino Valley found evidence of a complex society dating from the fifth century B.C. to the seventh century A.D. [2]. The aerial imagery revealed that settlements were far more dense and organized than previously believed, featuring domestic areas, storage spaces, and roads [2]. These findings indicate that ancient temples previously discovered in the area were not isolated outposts but rather located at the center of thriving rural communities [2].

Why it matters

The survival of the Marsican bear depends on mitigating human-wildlife conflict and protecting suitable habitat throughout the Apennine range [1]. Recent conservation efforts have seen some success, with a 2016 census identifying six reproductive females and ten pups [1]. Meanwhile, the use of drone technology offers a new frontier for archaeology, allowing scientists to map and protect hidden cultural heritage in dangerous or inaccessible mountain terrain without invasive excavation [2].
