Animals on the Dunes
Hundreds of plants and animals rarely found elsewhere in a county thrive on Cornwall's sand dune systems. The abundant flowers attract hundreds of different invertebrates. These bring the dunes alive with noise and activity.
The insects provide abundant food for breeding birds. These include whitethroats and stonechats and ground-nesting skylarks. Skylarks favour the semi-fixed dunes for nesting. They are easily frightened by humans and dogs, and may abandon their nests. The male skylark can often be heard singing high up in the sky. This is to distract predators from the nests and young birds on the ground. Buzzards and kestrels are often seen over the sand dunes. They are searching for young or injured rabbits, lizards or baby birds to prey upon.
Adders, slow worms and lizards may be found on the dunes. They can be found particularly on warm south-facing sheltered banks. Adders go into hibernation, over the cooler winter months, re-awakening in April. Adders, with their characteristic black and yellow zig-zag markings, are very sensitive to vibration and noise. They usually slither away when people walk near them.
Do not get too close to adders - they can inflict a dangerous bite.
Rabbits are also vital to maintaining the variety of habitats on the dunes through grazing. They are often considered pests on farmland. On the dunes however, they help to stop brambles and other scrubby plants covering over the flower-rich dune habitats. The rabbits live in burrows or hide in the bramble bushes. Foxes hunt rabbits on the dunes.

Reptiles and Amphibians
Some of the animals found on Cornwalls dunes may be threatened with decline. This is because they are very rare and are extremely vulnerable. Numbers of skylarks in Great Britain have declined significantly. This is due to habitat loss and increased use of pesticides. The rare sand lizard was completely lost from most of Britain's sand dunes. It was recently reintroduced to a couple of secret locations in Cornwall. It lays eggs in holes in bare sand. It was at risk of becoming extinct in this country, due to the lack of suitable breeding sites.
