The unstable cliffs between Sidmouth and the Dorset border are one of the most remarkable areas for invertebrates in the UK, as well as in Devon. They support many threatened speciesA group of similar organisms that can breed and exchange genes. More including speciesA group of similar organisms that can breed and exchange genes. More groups such as flies and beetles that are often overlooked. There are several reasons why this area is an invertebrateAn animal that doesn't have a backbone, such as insects, spiders, worms, crabs and slugs. More hotspot:
Unstable cliffs: The cliffs are some of the most active in Europe and are constantly being reshaped by erosion, slumping and crumbling. The resulting landslips are known as undercliffs. Constant bare ground is crucial for speciesA group of similar organisms that can breed and exchange genes. More like furrow bees, which burrow and nest in it. Other speciesA group of similar organisms that can breed and exchange genes. More depend on the vegetation that quickly colonizes these newly exposed areas.
Seepages: Many of the insects (especially the rare flies) rely on the mosaic of wet areas that run along the cliffs, including calcareous springs, seepages, streams and patches of fen. These features often appear on unstable slopes and frequent landslips prevent the habitatsThe natural environment in which an animal, plant or other organism lives.

Climate: The temperate climate along the coast (no extremes of temperature or drought) allows many speciesA group of similar organisms that can breed and exchange genes. More to thrive.
Diverse habitatsThe natural environment in which an animal, plant or other organism lives. More: The varied geology (chalk and mudstone cliffs), combined with the features above, creates a dynamic mosaic of scrubby, flower-rich grasslands (on the cliff tops and slumped cliffs), wetlands, rainforest-like undercliffs, bare cliffs and shingle beach dissected by wooded stream valleys (coombes). These intermingled habitatsThe natural environment in which an animal, plant or other organism lives. More support a remarkable diversity of rare invertebrates in a relatively small area and are why this stretch of cliffs and coast is so special.

Part of this area is designated as the Axmouth to Lyme Regis National Nature Reserve (see the LNRS Viewer). They also lie in the Jurassic Coast World Heritage Site.
