Riserva Naturale Regionale dei Calanchi di Atri (Oasi WWF)

The Calanchi di Atri are clay badlands west and south-west of the town. Deep gullies, sharp ridges and earth pillars create a landscape shaped by the interaction of marine sediments, runoff and vegetation.

Why it matters

The exposed clays were deposited in an ancient marine environment. Their erosion reveals the geological history beneath the cultivated hills of the Adriatic hinterland. The regional reserve, established in 1995 and recognised as a WWF oasis in 1999, protects both the landforms and their varied habitats.

What to notice

Rainwater cuts channels into sparsely vegetated slopes. In places, harder material shelters softer clay below, producing earth pillars. Bare surfaces contrast with grassland and scrub, while wetter gullies support trees such as willow and poplar. The crested porcupine is the oasis's emblem; birds of prey and butterflies form part of its fauna. Liquorice links the vegetation with Atri's cultural and economic history.

Context and history

Clearance and grazing contributed to the exposure of the clay, alongside natural processes. The local names Bolge and Scrimoni reflect the striking appearance of the eroded slopes. Protection has preserved a landscape that records both long geological change and the effects of human land use.
