Chalk reefs are a subtype of rocky reef. Rocky reefs are created when rocky outcrops (including limestone and chalk) crumble into the sea, providing safe nooks, crannies, and valleys for ocean life to attach or hide.

Rarity

"57% of coastal chalk in Europe is found in UK waters, which amounts to just 0.6% of our coastal habitat, making this an internationally important site for protection." - The Chalk Reefs of Cromer Shoal

Strongholds for Biodiversity

"Chalk beds are important because their cracks and crevices provide refuge for wildlife, especially juvenile invertebrates and fish. It is also a source of substrates for burrowing organisms." - Chalk Bed Marine Conservation

Subtypes of Chalk Reefs

Bubbling Reefs

"Bubbling reefs are formed by prolonged leaking of methane gasses from deep deposits (Jensen et al, 1992). The reef structures are formed in the near-surface sediment layer in a chemical process binding chalk to the sediment in an oxygenated sediment environment along the gas-seeping channels. Large bubbling reefs have caves and overhangs hosting communities dominated by hard bottom fauna on shady parts that are not found at the same water depth on nearby boulder reefs. Bubbling reefs in Kattegat are often located on sandy bottoms and thus significantly increase the complexity of these habitats.

The appearance of the reef structures above the seabed is due to erosional processes likely over very long time-scales. The structures are fragile and very sensitive to physical disturbance." - Ecologically or Biologically Significant Areas (EBSAs): Danish Kattegat

Chalk Flats

Instead of large pieces of chalk, these are flattened places made from chalk, which also allow wildlife colinization, including worms who burrow into the sediment.

Geography & Biology of Chalk Beds

"Cromer Shoal Chalk Beds MCZ supports a diverse range of habitats and species, within a relatively small area. Different habitats are not spread evenly across the MCZ. For example, chalk seabed typically gets more irregular with increasing distance from shore. Chalky seabeds supported much greater diversity than did clay seabeds. Seabeds with an irregular surface (eg with gullies and cobbles) supported more biodiversity than did less complex habitats." - Seasearch: Cromer Shoal Chalk Beds MCZ Report

Dangers to Chalk Beds & Chalk Reefs

Ocean Acidification

This poses an increasing danger to many ocean habitats, but perhaps especially chalk reefs, which are already extremely rare.

Ocean Acidification

"Currently, new anecdotal evidence shows that there may be impacts on chalk habitats from some fishing activities after all. But given the rarity of this habitat, we still need more evidence to improve our understanding." - Chalk Bed Marine Conservation

Commercial Fishing & Shellfish Hunting

Fishing and dredging have damaged these delicate eco systems. Abandoned fishing gear or "ghost gear" has also been found in these reefs.

Lobster & Crab Potting

These areas have been fished for hundreds of years, but modern equipment is harming these reefs.

Commercial Fishing

Beach Combers

A growing number of people are comming down to beaches in huge groups to fill builder's buckets with shellfish, damaging the coastline itself, and destabilizing the ecosystem by removing massive numbers of creatures from the marine food web.

Energy Production

Natural Gas

Natural gas fields are close to some of the UK's known chalk reefs.

Offshore Wind

According to the PDF, Vattenfall Wind Power Ltd Thanet Extension Offshore Wind Farm, there would be a chance of temporary habitat loss or disturbance while laying the electric cable for the wind farm, and possibly again for maintenance. The threat was considered low.

Sheringham Shoal and Dudgeon Offshore Wind Farm Extension Projects PDF states that "Cromer Shoal Chalk Beds MCZ is unique and protects features rare within English waters. Cabling could cause damage and loss of habitat within the MCZ which could put the conservation status of the MCZ at risk. The impacts from cabling are twofold. Firstly, the siting of the cable in the wrong location, such as in the chalk reef area, would cause irreparable damage to this habitat. Secondly, due to the location of chalk bedrock along the north Norfolk coast, cable burial may be difficult or impossible in some locations, increasing the need for rock protection. This would result in a loss of habitat. In addition, repeated cable burial works due to cable burial failure during the lifetime of the project could result in disturbance and damage to habitats within the MCZ." The document then discussed mitigation and plans to avoid damage to the reefs.

Oil Industry

Oil spills are considered a big threat due to the proximity of major shipping lanes.

Invasive Species

These have been outcompeting native species. Scroll down for a list of identified invasives.

Invasive Species

Water Pollution

Water pollution can reduce the amount of oxygen in aquatic eco-systems, which can suffocate species including corals. Pollution is also linked to sedimentation, which can again suffocate these important water-cleaning organisms.

Water pollution can increase water temperature levels, combining with the effects of climate change to exacerbate coral bleaching events. In addition the nutrients and toxic chemicals associated with polluted water can cause serious harm and malnutrition in corals. - Coral: The Vital Link Why Water Quality Matters for Coral Reefs

Toxic Contaminants

Continued & Improved Monitoring

"Natural England, as a statutory conservation agency, is obliged to monitor the marine environment, and to assess the condition of protected species and habitats. Making such condition assessments is challenging, time-consuming and expensive, so there is a clear need to explore options that support this process. One possibility is to use data from citizen science (like Seasearch)." - Seasearch: Cromer Shoal Chalk Beds MCZ Report

Fishing Industry

Dietary

Eat alternative foods, including plant-based proteins and seafood alternatives.

Fishing Industry

Boundaries of protected marine zones need to be better protected, with no dredging or bottom trawling allowed.

If fishing in the area, fishermen should adhere to the Code of Best Practice for potting in Cromer Shoal Chalk Beds Marine Conservation Zone (MCZ)

Seafood Alternatives

Energy Production

Proper surveys need to be performed before permits are given for projects. Mitigation should be planned with scientific and local collaboration.

Boating & Tourism

"Work with local, regional and national tourism organisations and businesses (in both England and France) to support initiatives that promote the sustainable use of assets within this SCT to people arriving by sea. Include information on the underwater environment, including particularly the area’s chalk reefs and the ancient creation of the Strait. Such visitor information should be readily available both upon port exit/ entry and on the ferries themselves." - Kent: Dover Strait Seascape Character Assessment (PDF)

The Seabed of Skagerrak "the northern part of the North Sea, is characterized by chalk reefs, gravel, gutters and sandy areas near land. Further out there are several successive rock reefs between the sandbanks, old peat- and forest floor, soft holes, seaweed forests and limestone peaks with sandy bottom areas between."

Skagerrak - Wikipedia

According to Wikipedia, "The Skagerrak contains some of the busiest shipping routes in the world, with vessels from every corner of the globe. It also supports an intensive fishing industry.[1] The ecosystem is strained and negatively affected by direct human activities. Oslo and Gothenburg are the only large cities in the Skagerrak region."

"The Skagerrak serves as a habitat for approximately 2,000 marine species, including a unique variety of Atlantic cod. It also contains sandy and stony reefs and cold-water coral reefs. Environmental institutions have expressed concern about increasing pressure on the ecosystem due to human activities and climate change. Protections are in place, with several marine protected areas in Skagerrak, including Ytre Hvaler National Park in Norway and Kosterhavet National Park in Sweden."

"... There are other chalk reefs in Kent and Yorkshire, where they are much flatter, but Norfolk’s chalk reef is the longest by far and probably the most rugged. It is a very special habitat.

The Chalk platform exposed along parts of the North Norfolk coast is not a new landform, in marked contrast to the Chalk platforms along the Channel coast which are being created by undercutting and collapse of often high Chalk cliffs." - The Chalk Reef

Worthing Lumps "have been given the acolade of 'one of the best chalk reefs in Europe (Marine Conservation Society) and is designated a Marine Site of Conservation Interest.It occurs about 8 km (5 miles) off the coast of Worthing, facing north running approximately south of ENE to WSW. The vertical cliff face rises to approximately 3 m (10.75 ft). At is base the seabed consists of broken chalk rubble, flints, gravel and shells of Slipper Limpet (Crepidula fornicata). The top is extensively covered with red algae, the cover of which varies throughout the year (storms can tear it off and deposit it on Worthing's and other beaches to the east).

The reef-face itself is heavily bored by piddocks, Pholas dactylus, and its broken nature provide numerous niches for a large range of marine life including molluscs, seafirs, seamats, tube worms, sponges and fish. The nooks and crannies and rich life also provide ideal nursery conditions for several species of fish, notably Black Bream which produce 'nests' close by to the reef..."

Loyalty Islands

"The atolls of the Loyalty Islands are built up as fringing reefs around raised limestone or sea mounts of volcanic origin. They are also underlain by a perched lens of fresh water which has created karstic erosion of caves and potholes, and their chalk cliffs are the remains of old raised atolls. Ultramafic soils cover a third of the main island and with the serpentine soils are nutrient poor but unusually rich in elements such as chromium and manganese. Lagoonal basins have a variety of substrates derived from terrestrial sediments nearer the coast or from degraded coral and shells further out, providing a soft muddy bottom, coral sands, or a mixture of the two The system therefore hosts an exceptional diversity of landforms, corals and their associated ecosystems, both continental and oceanic in character containing some 10,400 marine and 4,600 terrestrial species, many of them endemic and rare." - World Heritage Datasheet

Pacific Oysters

This paper lists different ways people have tried to combat this invader, and recommends "Removing individual oysters for immediate destruction on-site In Kent, United Kingdom, a trial was conducted by volunteers to combat Pacific oysters with the aim to return to former abundances. The trial lasted a whole year and was conducted simply by crushing the oyster shells one by one with ordinary handheld hammers (McKnight and Chudleigh, 2015). In the first-place whole oysters were removed but an unintended side effect appeared where the substrate was severely damaged. The substrate inhabited by the Pacific oysters were chalk reef structures declared as a fragile and protected habitat. To overcome that negative side effect the oysters were eradicated by crushing only the upper valve leaving the lower valve on the substrate. On non-protected chalk substrates entire individuals were crushed. The trial resulted in significant reduction of individuals' present leading to a habitat change from a dense oyster reef to a situation of less dense and mainly solitaire M. gigas on the location. The benefit was that the improved method was targeted on the alien oyster with minimal impact on the protected chalk formations and the naturally associated invertebrates but the disadvantage was the high cost of labor it required. McKnight and Chudleigh (2015) even did a cost benefit analysis of effectiveness and negative impacts from their oyster removal trial. They concluded this mitigation tool could effectively be used elsewhere if the goal sanctifies the means and the high cost is justified. In Northern Ireland, M. gigas individuals were crushed likewise. In the year after the eradication treatment oysters were almost 100% eradicated (Herbert et al., 2016). Hence, although labor-intensive and therefore relatively costly this simple mitigation strategy apparently works." This source offers a native vs invasive map of Pacific Oysters.

It uses biological records collected since 2005 that are held and curated by Seasearch, a volunteer underwater survey project for recreational divers and snorkellers.

This project uses Seasearch data and local knowledge for the spatial extent of CSCB MCZ to improve our understanding in three areas: spatial distributions of habitats and structural features; taxonomic diversity and presence of associations between species and structural features.

Knowledge about the distributions of habitats, patterns of diversity and associations with structural features has implications for understanding which areas are more vulnerable, sensitive or resistant to disturbance, which in turn may influence how the area is managed. It also provides a ‘baseline’ against which any future change might be assessed and identifies directions for useful work in the future."

Organizations

Europe

OSPAR "is the mechanism by which 15 Governments & the EU cooperate to protect the marine environment of the North-East Atlantic.

OSPAR started in 1972 with the Oslo Convention against dumping and was broadened to cover land-based sources of marine pollution and the offshore industry by the Paris Convention of 1974. These two conventions were unified, up-dated and extended by the 1992 OSPAR Convention. The new annex on biodiversity and ecosystems was adopted in 1998 to cover non-polluting human activities that can adversely affect the sea.

The fifteen Governments are Belgium, Denmark, Finland, France, Germany, Iceland, Ireland, Luxembourg, The Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

OSPAR is so named because of the original Oslo and Paris Conventions ("OS" for Oslo and "PAR" for Paris)."
