Conservation of Coastal Sites
Conservation of coastal resources has been practiced throughout human history as communities have endeavored to manage the food, water, and other resources of the coast in ways which ensure that each season or year will bring at least comparable bounty from the sea and the land. Protection of coastal sites in the historic past usually meant protection of areas to be used for elite recreation or as locations where coastal resources were to be conserved. Only in recent centuries, however, have communities begun to take specific action to conserve coastal sites for their natural flora and fauna. This has meant that some areas of coastal land and water have been designated as more important for conservation than others. This may have led to distortions in the behavior of coastal ecosystems which are just as important as the distortions which conservation is intended to prevent.
What does “conservation” mean? Usually, it means management in ways which protect the inherent natural and human features and processes of an area. Conservation is often confused with “preservation,” but natural features change. Change is normal, but it is usually a means by which sites retain their resilience.

Conservation for Biological Reasons
Ehrenfeld (1976) argued that protection of ecosystems was usually justified by two purposes: scientific and human. Typically, these include research and education, the need to protect genetic information, and as parts of the worldwide and interconnected pattern of ecosystems. Often, however, they have been protected because of the perceived importance of particular species. Usually, these are rare and, commonly, higher plants and animals. Conservation was often a response to particular lobby or pressure groups, sometimes even individuals, whose concern about losses of species and habitats led them to establish groups to provide protection to pressure governments into protecting vulnerable species. This was particularly the approach in nineteenth century North America and Europe. Today, the responsibility lies more with government bodies or conservation nongovernmental organizations (NGOs).

Archaeological and Historical Sites
Archaeological and historical sites include major buildings and structures located at the coast as well as sites where artifacts have been identified and excavated. Some sites are now well removed from their original coastal location by the effects of emergence, whereas others have been submerged. In shallow coastal waters, there are often very important submarine archaeological sites associated with wrecks, especially in the more active sea lanes. Some archaeological sites are at risk of disappearance as erosion cuts into them. Unless the site has considerable architectural or historical importance, erosional sites are usually not protected.
Although the purpose of conservation laws is usually the same, that is, the protection of features or processes of high scientific or cultural value, the detailed legislation depends upon the legal framework of each nation or state. France, the United States, the United Kingdom, and Japan each have well-developed systems of conservation legislation which lay down specific procedures for the identification, designation, and management responsibility for scientifically important sites. These include coastal sites. The way in which management takes place also depends upon local tradition and legislation. Thus in Britain, coastal conservation is carried out both by statutory bodies such as English Nature (a government body) and by NGOs such as the National Trust and the Royal Society for the Protection of Birds (RSPB). In addition, smaller local bodies such as Wildlife Trusts also own or lease land so that they can conserve and manage areas in which rare or endangered habitats or species occur. However, the statutory bodies often are advisory organizations rather than owners of the sites. Site management depends upon the landowner or occupier of the site. This means that there may be many different organizations involved on conservation of coastal sites within short distances of each other. Their conservation policies and practices may conflict.
In many countries, there is little or no tradition of nongovernmental conservation bodies practicing coastal conservation and so responsibilities lie with government. Thus in France, the government sponsored body, the Conservatoire de l’Espace Littoral et des Rivages Lacustres (CELRL) was established to make coastal lands more accessible at the same time as protecting landscapes and properties of national importance. Modeled in part on the UK’s National Trust, it is a governmental body rather than a nongovernmental membership body such as the National Trust. In some locations, First Peoples have traditionally regarded coastal lands as sacrosanct, but have no tradition of legislation to protect these lands. As a result, there are conflicts in conservation practice between traditional views of the value of coastal sites and their legal protection. Examples include the conflicts between European-based legislation and traditional approaches of the Maori in New Zealand. Legislation derived from British law conflicts with traditional law.
There may also be differences between local, national, or international legislation. Thus in the United States, both federal and state legislatures can define sites of coastal conservation and in Europe, the system of Directives which are mandatory on all member states may supplement or even override national conservation practices. The European Union’s Birds (European Commission 1979) and Habitats (European Commission 1997) Directives have established Europe-wide networks of sites including many at the coast. These are known as Special Protection Areas (SPAs) and Special Areas of Conservation (SACs). In Britain, the seaward boundary of coastal sites such as National Nature Reserves (NNRs) and Sites of Special Scientific Interest (SSSIs) established under the national legislation lies at Low Water Mark, but the boundaries of SACs and SPAs can extend to the territorial limit. There is a very wide range of types and levels of conservation designations worldwide which includes World Heritage Sites, Biosphere Reserves, and Ramsar Sites designated at international level, National Parks, and Marine Sanctuaries at national level and local nature reserves (Table 1).
Conservation Measures in Different Countries
In Europe, there are considerable differences in the history of coastal conservation, usually as a result of the relative importance of government and nongovernmental involvement and action at the coast. Furthermore, there has been considerable conservation action in the past decade as a result of initiatives by the European Community.
The preservation of animal and plant species and habitats which are either in danger of extinction in all or part of the national territory or have outstanding characteristics;
The restoration of animal or plant populations or habitats;
The conservation of botanical gardens and arboreta forming reserves for plant species which are rare, unusual, or nearing extinction;
Preservation of biotopes and outstanding geological, geomorphological, or speleological features;
Preservation or establishment of staging points on the great migration routes;
Scientific and technical studies necessary for the development of human knowledge;
Preservation of sites of particular interest for studies of the evolution of life and the activities of mankind.
This approach is reflected within the European Union Directives on Birds and Habitats both of which include important coastal areas.
The largest of the French coastal nature reserves is the Camargue (13,171 ha) on the Rhone delta. In contrast, when it was designated as a Site in 1930, Port Cros, a small island off the coast of Provence, had an area of only 140 ha. The initial designation was based on landscape protection, as more was known about the newly protected site, especially its flora and fauna, the significance of the surrounding seas was acknowledged. The site was extended in 1963 to include the surrounding sea, and became the first Marine Protected Area in the Mediterranean. The inclusion of the surrounding sea recognized the importance of such species as Neptune Grass (Posidonia oceanica) and Grouper (Epinephelus marginatus). This example typifies the development of coastal conservation as sites are first identified to protect a particular species or habitat and then expanded to account for improved understanding of the site and its surroundings. However, conservation can be very slow in practice. For example, at Port Cros the conservation objectives have been restricted by the impact of over half a million visitors annually and local resistance to conservation measures, such as a ban on angling from the shore which restricts traditional coastline activities.
The 62 coastal Départments may designate for protection the habitats of protected species that are threatened and acquire land financed through the Taxe Départmentale des Espaces Naturels Sensibles (TDENS: Departmental Tax for Sensitive Natural Areas), often in association with the CELRL (Meur-Férec 1997). The Law of May 2, 1930 allows for designation of either Site Classé (classified site) or Site Inscrit (listed site) for sites of special natural and built importance and has been used extensively in the protection of coastal sites (Meur-Férec 1997). The 1986 Loi Littoral (Coastal Law) provided a statutory framework which recognized the economic, social, and heritage importance of the coast and the unique nature of the coastal zone (Cicin-Sain and Knecht 1998). This provided a context for individual sites, including, for example, a setback zone of 100 m wide for the whole coast, in which development is prohibited. Marine areas can be declared protected under the 1968 Law of Maritime Hunting, essentially to protect wildfowl! In many countries with long-established traditions of hunting, conservation of these species has often meant controlled management of habitats. Although there are some strongly held objections to game conservation, it is important to emphasize that without these conservation measures many sites which are valued today for their biodiversity would not exist. The 1960 Loi Relative à la Création de Parcs Nationaux (Law for the Creation of National Parks) includes Marine Protected Areas (MPAs) by allowing the terrestrial parks to extend into the maritime region (IUCN 1994). European Union (EU) regulations and directives further supplement the national policies. Under the Birds (1979) and Habitats (1992) Directives, 133 sites have been proposed for inclusion within the European Community-wide Natura 2000 network of sites.
Two government bodies also have a role in French coastal conservation. The most important is the CELRL established in 1975. It is a public body charged with acquiring coastal and lakeside land, maintaining its ecological character and allowing public access to its sites (Cicin-Sain and Knecht 1998; European Union for Coastal Conservation 1995). Once purchased, the land is managed by the CELRL on behalf of the state in perpetuity. However, any acquisition has to take account of the area development plans and prior consultation with the Départements and Communes. This is because the day-to-day management and costs of an acquired site are handed back to the commune(s) or relevant landowner after purchase (EUCC 1995). It currently owns over 49,000 ha along 650 km of coastline (Meur-Férec 1997), including the D-Day beaches in Normandy and the Domaine de Certes at Arcachon. The Office National des Forêts (ONF, the National Forestry Office) manages 100,000 ha along 500 km of coastline, mainly forested dunes, such as the Landes. It works with the CELRL and other related administrative bodies to produce management plans for the forests. In the coastal region, ONF’s work is more social and ecological than its predominantly economic role on the inland forests (Favennec 2000). In particular, it is responsible for dune stabilization work, where it often has to balance the needs of conservation with tourism and public access. Thus at Pointe d’Arçay it has implemented a management plan devised with public participation and at Cap-Ferrat has successfully reintroduced marram grass (Ammophila arenaria) to the dunes.
Coastal conservation in Britain started, as so often there, with voluntary bodies such as the National Trust and the Royal Society for the Protection of Birds. Previously, conservation measures were largely in the hands of individual land-owners or the Crown and were mainly concerned with management of game or food resources. In 1949, the National Parks and Access to the Countryside Act established the Nature Conservancy as well as the national parks. The Nature Conservancy and its successors (three country agencies: English Nature, the Countryside Council for Wales (CCW), and Scottish Natural Heritage) were concerned with the geological and biological importance of sites for research and education. National Nature Reserves were established together with areas designated as SSSIs. The Royal Commission on Historical Monuments describes and studies sites of historical and archaeological importance, including many coastal sites. The Ancient Monuments and Archaeological Areas Act 1979 provides for the protection of archaeological sites and monuments and does appear to extend into territorial waters, although there is no record of designations at sea. These Acts and bodies are generally empowered only to deal with sites above Low Water Mark. However, the European Directive on Habitats specifies Marine SACs and so specific attention now has to be given to subtidal and submarine sites around the UK coastline. The Directive has force for the coastal waters of all European member states, although the detailed legislation is made at national level.
Submarine and marine sites are dealt with under different legislation. The Merchant Shipping Act 1995 deals with wrecks and salvage, requiring reporting of finds and the Protection of Wrecks Act 1973 provides some protection for important or dangerous wrecks or their sites. War graves may be designated under the Protection of Military Remains Act 1986: diving on and interference with a designated war grave is an offence. International agreement to protect graves in civilian shipwrecks in international waters was given effect in the Merchant Shipping and Maritime Security Act 1997.

The position within an ecological or geographical unit;
The potential natural value of a site;
The intrinsic appeal of a site.
The Nature Conservation Review identified 140 coastal SSSIs with a mean area of 1,957 ha; 8 sites exceeded 10,000 ha in area. At the same time, France had 131 sites of average size 456 ha. 78% French sites were less than 100 ha in area, whereas 42% British sites exceeded 1,000 ha. For coastal geomorphological sites, criteria have included not only the specific importance of the site, but also the processes affecting particular rock-types or structures. As a result, sites with comparable geological conditions have been selected with micro- and meso-tidal ranges and different wave climates. There are 100 geomorphological sites which include large shingle structures such as Dungeness, major landslides such as the west Dorset coast, major dunes such as Morrich More on the east coast of Scotland, and world-renowned features such as Lulworth Cove and the stack of the Old Man of Hoy.
Although their coastal conservation is based upon different traditions both in coastal use and in their laws, France and Great Britain show very well how complex the legislation and administration of coastal conservation has become. Countries with shorter experience have been able to adopt different, and sometimes more efficient, approaches. Furthermore, the European Community has adopted its own framework for conservation in order to establish a community-wide network of related sites.
Typically, the largest voluntary bodies have strong marketing and sales departments. Funding from national and local government is limited in amount and has to be competed for. Such funding is often restricted in time. In contrast, in France or the United States, for example, conservation is predominantly funded by official sources, with the national and local governments largely responsible for both funding and operation of the conservation sites. The manner and volume of funding may change with a change of government. Thus, although the arrangements shown in Fig. 1 for government funding applied in 2000, a reorganization of government departments following a General Election in June 2001 altered some of the responsibilities. In Britain, local authorities have only limited inputs into conservation funding, whereas the French Départements have considerable fiscal and legal tools at their disposal. They may, for example, acquire land financed through the TDENS (Departmental Tax on Sensitive Sites). Often these acquisitions are made in conjunction with the CELRL, and all the 62 coastal Départements have used these powers to purchase land (Meur-Férec 1997). The day-to-day management and costs of an acquired site are handed back to the commune(s) or relevant landowner after purchase (EUCC 1995). The majority of funding comes from the state but legacies and public/corporate donations also help with the acquisition and management of sites. Apart from the State, the CELRL is France’s second largest landowner but interestingly, its budget is one-fifth of the National Trust’s, a British NGO that operates a similar protection by acquisition policy (Meur-Férec 1997).
At the time of the French Law of 1976, many European countries had hardly established relevant legislation. Greece, for example, had very good legislation concerning its archaeological sites, but was only just beginning to identify natural sites (May and Schwartz 1981). Similarly, Norway’s Nature Conservation Act of 1970 initiated action to preserve and protect plants, animals, and birds and areas of importance to nature conservation which, within a decade, established a network of 13 national parks, almost 200 nature reserves and over 200 locations which were of natural scientific importance. Many are at the coast. In contrast, Poland created its first National Park inland at Bialowieza in 1932 and there are now eight protected coastal areas including two National Parks, the Slowinski (founded 1967: present area 18,619 ha) to the west of Gdansk and the Wolinski Park near the German border (founded 1960: present area 10,937 ha). The Polish Environmental Protection Bill 1992 provides for three “levels” of designation: Strict (usually no admission to the public: 22% of sites), Partial (where management controls are flexible: 59%), and Landscape Protection (where so-called “soft laws” apply: 19%). This recognizes that although some areas must have strict controls over access in order to protect sensitive areas and species other areas are more resilient and more appropriate for human activities such as recreation. National ecological policy requires that 30% of Polish territory (including coastline) should eventually be designated as “protected,” 22% of the area had been designated by 1997. Coastal conservation in Poland is thus a national responsibility rather than a regional or local one. This is a typical pattern of many countries which have relatively recently begun to conserve coastal sites. The strength of national legislation often, but not always, ensures that designation and appropriate funding occur.
Spain combines national and local approaches to conservation. It has a long history of environmental legislation but the first specific conservation (in its modern sense) legislation was the 1975 Law on Espacios Naturales Protegidos (ENPs: Protected Natural Areas). This proposed four categories of protected area: national park, natural park, natural area of national importance or interest, and reserve of scientific interest. Other later laws have established over 25 different categories (WCMC 1992). The national body responsible for administration of protected areas is the Instituto Nacional para la Conservación de la Naturaleza (ICONA: National Institute for the Conservation of Nature). Set up in 1971, its functions include the encouragement of renewable resource use and maintenance of ecological balance; the creation and administration of national parks and sites of national interest; and the development and exploitation of inland fishing and hunting assets. With decentralization of the government in 1978, responsibility for many conservation issues passed to Spain’s 17 autonomous communities (Comunidades Autonomas) which are responsible inside territorial waters for the protection of marine and coastal areas from human activities. The 1989 Law on the Conservation of Natural Areas, Flora, and Wildlife strengthened this responsibility further. The protection of coastal areas is covered by the Ley de Costas (the Shore Act: July 28, 1988) based on the French model (Barragan 1997). The Shore Act requires protection of the sea up to 100 m offshore and restricts the number of road and pedestrian routes to the coast. It also defines a zone extending 500 m inland which affects land and urban planning as well as prohibiting the disposal of waste in this area (WCMC 1992). As in France, this provides a national framework within which conservation of coastal sites may take place. Laws concerning sustainable use and conservation of living marine resources have been adapted from the Directives of the European Community since these require member states to bring them into force.
The Waddensee: An Example of International Cooperation in Coastal Conservation
Careful decision making – based on using the best available information
Avoidance – avoiding potentially damaging activities
Precautionary principle – avoiding damaging activities, even if there is insufficient scientific evidence to link them to specific impacts
Translocation – moving damaging activities to areas where they will cause a reduced impact
Compensation – using compensatory measures to offset unavoidably damaging activities
Restoration – restoring areas which have been damaged
Best available techniques and best environmental practice should be adopted.
The most important lessons are that international cooperation is essential for the conservation of some vital sites, that there must be agreed targets and procedures, and that local people must be involved especially when their traditional activities form part of the ecosystem as a whole.
In contrast, although some of the less-developed countries of eastern Europe have taken few steps to conserve coastal sites, the role of international conventions such as the Ramsar Convention on Wetlands of International Importance, 1971 and international cooperation in species protection, especially for marine turtles, have had an impact. In some respects, the significance of tourism as an economic driver for conservation has been overlooked although tourism provides a very strong incentive for conservation and sustainable activities. In Albania, for example, the isolation and centralization of the economy and society over the last 50 years affected community behavior as local communities were excluded from the planning process and decision making about natural resources upon which they depended. Not surprisingly, they consider that conservation and habitat protection have ignored their needs and imposed restrictions without providing benefits.
Albania designated its first Ramsar site in 1994 (RAMSAR 1996, 2001), comprising the Karavasta Lagoon and adjacent Divjaka National Park. In the 1960s, much of the wetland was drained for agriculture, affecting the biodiversity of the lagoon, as well as the surrounding catchment, the Divjaka forest and hills, and its human communities. The total area of the site is 20,000 ha, made up of native forest of Pinus pinea, a species unique to the Albanian coast, and the lagoon itself (5,800 ha) which is a brackish water system connected to the sea by artificially maintained channels. The freshwater input to the lagoon comes from runoff from the surrounding agricultural land and Divjaka hills. Karavasta Lagoon has the only coastal breeding population of the Dalmatian pelican (Pelecanus crispus) along the Adriatic and Ionian coasts, supporting up to 5% (700–1,000 individuals) of the total world population. A significant proportion of the European breeding populations of Little Tern (Sterna albifrons) and Collared Pratincole (Glareola pratincola) use the Karavasta wetlands during migration, as well as large numbers of waterfowl, gulls, and terns, including the globally threatened pygmy cormorant, and white-headed duck.
Despite its designation as a Ramsar site, the lagoon has been seriously threatened by inappropriate tourism development which has often damaged fragile coastal habitats upon which its wildlife depend. Pollution and overfishing have added to the stresses on the lagoonal ecosystem. Some of the reclaimed wetlands are affected by high levels of salinity and so are of limited agricultural value. The area is state-owned and managed jointly by the General Directorates of Forestry and Fisheries (both part of the Ministry of Food and Agriculture). In practice, management depends upon a small number of rangers with limited experience of specialized wetland management, training, or equipment. Future strategies include improved planning and management of the lagoon to both protect the ecosystem and its biodiversity (including the pelicans) and derive economic benefits for local communities. A management plan for the site was prepared with international, technical, and financial cooperation through the European Union’s PHARE program (PHARE 1996). The Karavasta Lagoon is an example of where there is a need to involve local communities in biodiversity conservation activities and demonstrate their benefits. Karavasta exemplifies the problem that conservation of coastal sites depends upon management of the human systems which decide how the area will be sustained.
The United States of America
A very wide range of different designations are used in the United States, many within the framework of the National Parks legislation. They range from areas such as National Parks where they exist for both preservation of natural and cultural features and for recreation to specialized research areas, such as the National Estuarine Research Areas that are devoted to research (Table 1). There is a wide network of sites at state and federal level, but the initial establishment of important sites depended upon very strong individual lobbying of the federal government and the role of individuals such as John Muir in getting presidential support. Coastal sites were generally established later than inland sites.

In many less-developed countries, funding for conservation is largely provided through tourism receipts, or by international aid programs and funding from international bodies such as the World Wide Fund (WWF) for Nature. Pressure for conservation action and designation typically comes from pressure groups. The implications of conservation action and site or species protection are not always well considered. For example, a ban on turtle fishing along the Pacific coast of Mexico had immediate impacts upon the local economy and knock-on effects to other parts of the coastal ecosystem. The contrast between the approach in many less-developed, but biologically rich, regions is well demonstrated by two examples, Costa Rica and the Mexican state of Oaxaca.

Mazunte: An Example of Conservation in Action
Mazunte on the Oaxacan coast of Mexico is, unlike the Waddensee, in one of the poorest areas of the world. It shows how changes in conservation policy can be accompanied by local community involvement in coastal conservation especially when this is focused upon sustainable development. However, it also demonstrates the tenuous nature of much coastal conservation in less-developed areas.
For more than 30 years, Mazunte (the name comes from a Nahuatl word meaning “please lay eggs”) was dependent upon turtle catching and canning. Most people in the village were either fishermen or worked in the cannery. A Presidential decree in 1990 banned all turtle fishing following significant lobbying by WWF. The immediate effect was to remove the community’s main source of income, as the local community express it, throwing “our people into misery!” Protection of one species (turtles) was enacted at the cost of another. Some local people abandoned the area and moved inland to occupy land within the coastal dry forest, the associated clearance having potentially damaging effects on coastal lagoons as sedimentation increased. The turtle populations were recognized as being under stress from poaching, predators, and disease. The Mexican Center for Marine Turtle Research (CMT) was established in late 1991, using the buildings of the former Society of Industrial Fisheries of Oaxaca, and now has a unique role as the only center which studies seven out of the eight species of marine turtle. In addition, a community-based project known as Ecosolar and a Reserva Ecologica Campesina were established. Within Mazunte itself, a small ecotourism project was based upon sustainable principles and designed to provide accommodation for mainly foreign visitors to the area. Further to the south, the large-scale resort development of Huatulco had a major impact on the unusual dry coastal forest and the coastal beaches and lagoons.
The attempts to conserve not only the turtles and their nesting beaches but also to build a sustainable community have not proved easy, for both human and natural intervention have conspired to threaten the coastal ecosystem. In the aftermath of an uprising in 1994 in Chiapas, there was considerable local unrest which affected Huatulco in August 1996. This had a serious impact on the turtle ecology because, when police were sent to the resort, up to 200 poachers went to local beaches where Olive Ridley turtles were arriving to lay eggs. It is estimated that up to one million eggs were lost and large numbers of turtles killed. In October 1997, the area was struck by Hurricane Pauline which caused serious damage to both the CMT and other buildings but also devastated the nesting beaches. 806,000 nests were affected, with half all the nests on Escobilla beach, four million eggs and up to ten million hatchlings lost. Nevertheless, the turtles continue to nest on these beaches. The CMT carries out detailed studies of turtle behavior and ecology both in the Center and on the beaches and the growth of the resort of Huatulco has brought increasing numbers of visitors to Mazunte. The concept of the Reserva Ecologica Campesina is unusual in that it links deliberately the human community with the coastal ecosystem. Knowledge which once served the commercial interest of turtle canning has been harnessed to develop an approach to sustainable development which has shown itself to be very resilient to significant human and natural disruption. The financial support for the CMT is very small, less than US$70,000 annually, and receipts from the ecotourism project are also small. Conservation here is not about conservation of a site, so much as conservation of a whole ecosystem (including its human occupants). For many communities, this will be the future for coastal conservation for it is firmly based in local knowledge, the needs of the local community, and their own initiatives.
The conservation of coastal sites takes many different approaches, often with detailed legal and administrative frameworks for designation and protection, but also in relatively informal ways with the involvement of NGOs and private ownership. In some countries, it has only been through the effective active involvement of individuals and NGOs that conservation has been put into practice. The example of Mazunte is a modern, but more community-based, expression of people’s wish to protect and conserve features of their environment which they value which was expressed in different words and actions by the founders of the National Trust or John Muir and the Sierra Club. Once established, such initial routes to coastal conservation need the support of the national and international communities to make sure that they are truly sustainable and not threatened by external political, economic, and social pressures. Although coastal conservation is well established in practice, there are nevertheless enormous threats to many sites from urbanization, resource extraction, tourism, pollution, large-scale coastal projects such as barrages, and reclamation and neglect. Sea-level change and climate change also threaten many sites, although their history shows that most sites are resilient to change provided that human activities allow natural resilience.
The International Union for the Conservation of Nature (IUCN) World Conservation Monitoring Centre (WCMC) in Cambridge, England, is the most important source of information regarding protected sites.
