Nature and Wildlife Walk in Trevose Head and Bedruthan Steps

6/25/2021

Great day out! Nature and wildlife walk in Trevose Head and Bedruthan Steps. Nothing beats the spectacular, dramatic and rugged North Cornwall Coast. Rich and diverse flora and fauna. Love it.

Trevose Head (Cornish: Penn Trenfos, meaning farm of the wall's headland[citation needed]) is a headland on the Atlantic coast of north Cornwall. It is situated approximately 5 miles (8.0 km) west of Padstow. The South West Coast Path runs around the whole promontory and is within the Cornwall Area of Outstanding Natural Beauty and the Trevose Head Heritage Coast.

The headland is within the Trevose Head and Constantine Bay Site of Special Scientific Interest (SSSI) which is designated for both its biological and geological interests. Wild asparagus grows on the cliffs of Dinas Head and shore dock at the base of the cliffs. The cliffs are also important for breeding fulmar, razorbill and guillemot.

Carnewas and Bedruthan Steps (Cornish: Karn Havos, meaning "rock-pile of summer dwelling" and Cornish: Bos Rudhen, meaning "Red-one's dwelling") is a stretch of coastline located on the north Cornish coast.

The section of coastline from Carnewas to Stepper Point is part of the Cornwall Area of Outstanding Natural Beauty[9] and subject to special landscape protection. In addition, Bedruthan Steps and Park Head is an 80.8-hectare (200-acre) Site of Special Scientific Interest, designated for its geological and biological interest in 1951. The site was subject to a revision in 1973 and renotified in 1986. It is noted for its slates and fossils from the Middle Devonian period, various mosses, and beetles. Bedruthan Steps is also a Geological Conservation Review site because it is a ″source of rare fish specimens″, which were first reported in 1848 by W Pengelly.

Flora:
The coast here is exposed to westerly winds and the clifftops provide an exposed environment best suited to low-growing plants. Flowers to be found along the cost between Mawgan Porth and Bedruthan include Bird's foot trefoil, Kidney vetch, Sheep’s-bit and Spring squill, plus the distinctly maritime species Sea Pink (Thrift) and Sea Campion.

Geology:
The bedrock at Bedruthan Steps is at the northernmost extent of a series of sedimentary rocks classified as sandstone, siltstone and mudstone and known as the Bedruthan Formation. The underlying rock from Bedruthan Steps to Trevose Head is Middle Devonian slates (386–377 Mya) with Staddon Grits to the south towards Trenance Point. The thickness of the slates have been estimated at over 2,000 m (6,600 ft). Marine erosion by the sea carrying sand and pebbles has worn away the weaker, softer rocks to leave the stacks seen today. Fossils of fish, corals, trilobites, etc. have been found in the Eifelian slates on Samaritan and Pendarves Islands. Few fossils are useful for dating here, but one (although considered to be problematical) Pteroconus mirus dates the formations to the Eifelian. At the end of the headland of Park Head (grid reference SW840708) is a subvolcanic rock, Diabase.

Dark Sky discovery site
In 2014, the area was granted "Dark Sky" status by the Science and Technology Facilities Council. Dark Sky discovery sites must be free from light pollution and have good views of stars and the Milky Way, and be accessible to the public.
