In this article we provide an overview of five case studies of initiatives using the image of White Stork as a focal species. Our case studies are preceded by a short overview of existing approaches to achieve broader environmental goals through species conservation and a review of the social, ecological and social-ecological importance of White Stork. With the use of the above, we investigate linkages, complementarity and friction between the ecological, social and social-ecological perspectives on focal species, and eventually propose a framework for a more multi-targeted approach. The proposed concept of a social-ecological keystone species recognises social-ecological system complexity and goes beyond traditional divisions into ecological and social. Our approach extends the cultural keystone species concept to tie into new spheres – modern societies with more indirect connections to nature as well as indigenous communities, and all forms of human relationships with other species, not just for consumption – and to explicitly include the ecological significance of a species. Apart from serving as a potentially highly useful conservation proxy, a social-ecological keystone species emerges as a vehicle for ecological literacy, expanding from an interest in a species to learn more about the system of which it is part. White Stork, with its long history of coexistence with humans and many linkages with specific cultural practices offers an excellent example for discussing the broader social-ecological relevance of species in establishing meaningful connections to nature.
Social-ecological keystone species, keystone species, flagship species, cultural keystone species, social-ecological systems
Conservationists select certain species as a focus of their activities – or at least for public relations or visibility purposes (
We provide an overview of the different perspectives on what constitutes particularly important species present in environmental conservation and social sciences, and eventually bring these different perspectives together to scrutinise the White Stork (Ciconia ciconia). The example of White Stork helps us identify outstanding issues that need to be addressed in future discussions on focal species. White Stork holds a particularly high social/cultural status in most areas where it is present (
Several concepts have been proposed to denote focal species, organisms particularly important from the point of view of nature conservation, each with its own “myriad of definitions and applications” (
Concept | Definition/understanding |
---|---|
Keystone species | Species that has a particularly significant impact on the state of a community or an ecosystem (disproportionate to the species’ abundance or biomass) ( |
Foundation species | Highly interactive and abundant species, playing a dominant role in an ecosystem, a less restrictive variant of the keystone concept ( |
Umbrella species | Species which have relatively large habitat/area requirements and saving them automatically saves many other species ( |
Indicator species | Used to monitor environmental conditions and community/habitat/ecosystem composition ( |
Concept | Definition/understanding |
Flagship species | “Popular charismatic species that serve as symbols and rallying points to stimulate conservation awareness and action” ( |
Charismatic species | “Immediately recognizable and identifiable by name, (…) commonly associated with a particular geographic location or habitat” ( |
High-profile species | Often used in exchange for flagship, widely recognised species (e.g. |
Poster species | A species which qualifies to be used on a poster promoting a given conservation campaign ( |
Iconic species | Reflecting the “wider social, economic and ecological roles” of those species ( |
Symbolic species | Holding a symbolic, cultural, religious value, e.g. an animal serving as a national emblem (e.g. |
Totemic species | Bearing special, totemic importance for indigenous communities ( |
Species that sells | Used to ‘sell’ conservation ideas or objectives, attracting funds to conservation ( |
Tourism flagship species | A species of particular importance from the point of view of attracting tourists ( |
Species with a high wow-factor | Quantification of relative interest levels for different species based on pair-wise comparisons. A measurement of an observer’s relative level of enjoyment derived from spotting such species in the wild ( |
Bambi effect | Cute and cuddly, anthropomorphic and sentimentalised, activating “protective instinct which prevents humans wanting to kill or consume animals” ( |
Local flagship species | Species which are important to local people and are used purposefully to promote conservation within local communities ( |
Some authors (e.g.
However, to some extent, all of these concepts involve social and ecological aspects, albeit to a varying degree. The perceived ecological importance of species is based on social knowledge, cultural norms and values. Conservation projects are built on the knowledge of their authors and preferences of their sponsors. Modern approaches to conservation often draw on local traditional knowledge, citizen science and many other forms of stakeholder involvement (
Meanwhile, the socially oriented selection frameworks involve at least some level of ecological knowledge, at the very least on the part of those who promote certain species as socially important. Flagship species may be selected based on their conservation status (
Many authors have already argued that flagship species would serve their purposes better, had they not only reflected their social importance but also the ecological importance (
These ideas are quite comprehensively reflected in the concept of cultural keystone species (
Although cultural keystone status does not necessarily coincide with the ecological prominence of those species, it often reflects the traditional ecological knowledge. As a result of the strong dependence of indigenous communities on nature, ecologically “valuable” species tend also to be socially valuable. However, this is not always the case and it does not have to reflect the specific keystone, indicator or umbrella status of a species. It does, however, underline the co-evolutionary character of social-ecological systems and again suggests that any understanding of a species’ importance is a social construct.
Based on a literature review, we describe the importance of a selected well-known species, which often serves as a conservation conduit – the White Stork. The selection of literature for this review was aided by our previous work on this species. In line with the overview of the different perspectives on particularly important species presented in the previous section, we divided the results of our review into the ecological, social, and social-ecological aspects.
To provide an in-depth analysis of the articulation of the focal species concept in the case of White Stork, we pay special attention to five case examples, mostly drawing from recent conservation practice. For each case study, we investigated the involved stakeholders, the time of a campaign, its objectives, addressees (and what was expected from them), activities involved, communication channels used to reach the relevant audiences, and outcomes. We also analysed in which way the White Stork was used in a given campaign, and what it symbolised.
The existing frameworks for selecting focal species serve as the basis for our social-ecological account and the case descriptions reflect the most important issues addressed in the concepts developed so far, complemented with a broader social-ecological systems thinking. The description of each case study is based on the review of publicly available resources, combined with additional information sought from the relevant project representatives.
Among farmland birds, the White Stork seems to be a good indicator of both environmental conditions and habitat diversity (
The presence of White Stork provides benefits to other species. White Stork nests are known as good nesting sites for other bird species (
From the point of view of agriculture, White Stork probably plays an important pest regulative role as it feeds, among other species, on the Common Vole Microtus arvalis, which can cause serious damage to crops, especially in meadows, pastures and perennial crops (clover, alfalfa). Indeed, in the so-called murine years the number of pairs of storks and their reproductive success increase (
Several accounts of the special cultural importance of White Stork have been published in national languages in countries where White Stork is present, indicating the prominent cultural role of this species (
White Storks are widely represented in art, which is not only restricted to literature, paintings and folk arts, but extends to applied arts and industrial design, including toys, jewellery, household appliances, clothes, souvenirs and various collectible goods (postcards, stamps, phone cards, beverage bottles etc.). They serve as important symbols, being considered one of the key ‘national birds’ by the Belarusians, Danish, French, Germans, Hungarians, Lithuanians, and Polish. For example, they are featured in national promotional campaigns in Poland, and in local coats of arms in Poland and elsewhere (e.g. the Hague). Furthermore, the image and symbolism of White Stork is also exploited for commercial purposes by companies ranging from infertility treatment clinics, through restaurants and hotels located close to storks’ nests, an on-line shop offering Polish produce to Polish immigrants in the UK, to many companies offering products and services seemingly unrelated to storks (see our case study 5 which solely relied on the symbolic meaning of the stork, without any consideration of environmental facts and factors). Finally, because of their familiarity, White Storks are frequently used in ecological education projects, with one database featuring several hundreds of such undertakings in Poland alone.
Although White Stork is a particularly prominent species, especially from a cultural perspective, its significance is different than in the case of species traditionally used as examples of cultural keystones (
Here, we focus on the role of White Stork in European countries where this is a widely known and common species (such as Poland, Lithuania, Hungary or Germany). We see the national level as the most relevant for discussing the concept of a social-ecological keystone species in a modern, industrialised society, although we also admit that such an analysis could be performed for a distinguishable cultural group. Clearly, in a modern society, dependence on a species is more indirect, not necessarily involving the direct, instrumental or use value related to consumption. White Storks are charismatic enough that almost everyone derives satisfaction from observing them as part of a traditional rural landscape. So the criteria from
Additionally, as already indicated, the social-ecological perspective should not only suggest that the species is important because of co-evolutionary interdependence between the social and the ecological, it should also reflect a more objective ecological role of a species in question. Although the White Stork is not a keystone species, it is still important enough in an ecosystem, either as an indicator or – at least to some extent – as an umbrella species, that it fits into the broader concept of a social-ecological keystone species. This indicates the relevance of the local flagship species concept (
Does the White Stork meet criteria for a cultural keystone species? Criteria from major articles on cultural keystone species and the related concept of a local flagship species have been collated in rows according to their relative proximity.

In 2013, referring to the importance of White Stork for the Polish society, several environmental NGOs (led by Grupa Ekologiczna) started to put pressure on Lebanese authorities to take action. Simultaneously, in cooperation with the Polish embassy in Beirut and Lebanese conservation organisations, they launched an educational campaign in Lebanon, highlighting that the Lebanese society has important responsibility to protect storks on their way to and from Poland. The involvement of the diplomatic mission stressed that killing migratory birds (storks in particular) negatively affected the image of Lebanon in Poland. In Lebanon posters, leaflets and a video documentary were distributed in schools and research organisations, at public events, and among other interested stakeholders, along with some organised presentations on this topic. In 2015, a photo contest was organised for the best photo featuring White Stork, with a trip to Poland to take part in ringing storks as the first prize. In Poland additional awareness raising activities were carried out through the use of traditional and social media, with several opportunities for the general public to get involved in this campaign (e.g., sending emails and postcards to the prime minister of Lebanon). Satellite tracking of one stork during its migration – especially when crossing the territory of Lebanon – attracted additional attention to this campaign in both countries. The campaign has continued in subsequent years; in 2017 Polish activists showed a 10-minute animated cartoon in Lebanese schools, and distributed 1000 copies to Lebanese children. Over time, this campaign has raised interest in Lebanese and Polish media. It has led to regulatory changes improving conservation and a higher determination to execute the law in Lebanon (level of government), and hopefully increased awareness among the general public.
As a charismatic, flagship species, White Stork was able to attract broad attention to the problem of illegal bird hunting in Lebanon (or to “sell” the broader conservation objectives). However, most prominently, this case study presents White Stork as a social-ecological keystone species, or at least a local flagship species.
Since 1994, EuroNatur awards the European Stork Village title to a village that protects a White Stork nesting colony and in this way helps to reverse the loss of traditional agricultural habitat. Local stakeholders in European Stork Villages are expected “to enhance the living conditions of the White Stork, such as preserving or rewilding large open wet meadows or erecting artificial stork nests” and to increase environmental awareness of inhabitants and visitors (
In Central and Eastern Europe White Storks currently usually nest solitarily. Although the several dozens of colonial nesting sites of White Stork in Poland are seen as spectacular natural spots, few have been successfully marketed as tourist attractions and even fewer have become the focus of large-scale conservation activities. Zywkowo in the north-east of the country provides the best example of a combination of both objectives. Conservation and tourism promotion activities have been carried out there since 1997 by the Polish Society for the Protection of Birds (PTOP) within the “Stork Village” project.
As a conservation organisation, PTOP has been primarily interested in protecting natural habitats and biodiversity, which have been increasingly exposed either to development pressure (especially intensive agriculture) or to changes related to land abandonment (afforestation, secondary succession). To counteract these pressures, which would have resulted in the loss of the typical landscape mosaic and the storks’ foraging grounds, PTOP attracted significant funding from international and national donors to buy and lease land, renovate buildings, maintain an organic farm with traditional breeds of horses and cows, and create tourist infrastructure. Subsequent projects were carried out not only in Zywkowo, but also in several other “stork villages” in north-east Poland, all of which aimed at the conservation of natural foraging grounds for the storks (increasing water retention and improving water quality, supporting extensive agriculture, improving the storks’ nesting conditions etc.). Seven villages have been connected under the Warmian-Masurian White Stork Tourist Trail, with some national scale promotional activities, including brochures, posters, website, basic tourist infrastructure, ecological education activities and infrastructure, and national media coverage. Zywkowo has remained the most popular village within the trail, annually visited by 2000–5000 tourists (c.f.
Local stakeholders in stork villages are expected to contribute to nature conservation and to increase environmental awareness of inhabitants and visitors. Thus, White Stork serves as an umbrella species (for other species, for landscape mosaic, for the whole ecosystem) and a tourism flagship species. The different projects carried out by PTOP in this area have been successful in preventing the degradation of the stork habitats, and they have also attracted tourists to stork villages. This further indicated that the potential of birdwatching tourism is higher than usually assumed, because it involves not only specialised tourists, but also casual ones who are lured to attractions such as stork villages (
The first half of the 20th century saw the decline and final disappearance of White Stork from Sweden, with the last unsuccessful attempt at breeding in 1954 (
The programme aims to bring back free, breeding and migrating storks to Sweden and much of the media attention and public focus is on the breeding programme (storks were first brought in from Algeria via Switzerland, later Poland). However, the reintroduction programme is paralleled by landscape restoration efforts, primarily aimed at restoring wetlands and it was early progress here that convinced SSNC and SkOF that it was time to start with the Swedish Stork Programme (
The stork is described as a flagship species in text written by the Stork Programme and in information relating to the programme. Depending on audience and objective we contend that the stork, as used in the region, can be considered a flagship species, an umbrella species or an indicator species. Participation in the restoration programme has also been used by municipalities and organisations to brand their environmental engagement. The stork is the main attractor for tourism, guided tours, environmental education and public engagement in nature conservation, all of which fit in well under the flagship identity. However, because of the stork’s role in maintaining the culturally meaningful landscape, the stork bears a deeper social-ecological meaning. Indeed, the success of the reintroduction programme is also used as an indicator of the progress of the landscape restoration efforts, and by implication (and often explicitly stated) biodiversity conservation or promotion.
“Almost gone” campaign was launched in 2009 to attract interest and funding for nature conservation, focusing on the problem of disappearance of seemingly common and widely known species. Using examples of species that have experienced significant population declines in Germany in the past decades, the campaign informed that extinction may also concern familiar, national species, which most people do not consider threatened. These included White Stork, Wolf, Tree Frog, Apollo Butterfly and Cod, each of which could only be seen in part, disappearing from the picture.
The campaign included over 4700 posters displayed in billboards in all major German railway stations and along major roads, plus online banners, flyers and postcards, and short commercials shown in regional television channels.
The stork was selected as one of the flagship species because it is familiar to everyone and yet the risks that it faces are not so well-known. Although the stork typifies many animal species that are threatened with extinction (at least in Germany), its importance was reinforced by the fact that this species is featured in NABU logo (i.e. an iconic or totemic species). Along with other species, the stork was also partly considered an indicator species because its presence was connected to the condition of its habitats (and to habitat loss).
Atlas, the largest Polish manufacturer of construction chemicals, is widely recognised not only for its products but also because of its association with White Stork, which the company has been using as its symbol and mascot. The company was established in 1991, in the early period of Polish socio-economic transformation, and it started to use White Stork in a large scale outdoor advertising campaign already in 1993. Since then, about 1500 advertisement poles featuring the company’s logotype and a laminate White Stork on a nest have been planted all over the country (about 1250 remain until today). This campaign was so successful in making the brand widely recognised and popular that White Stork has become the central concept in subsequent promotional activities (“everything else was thought around the storks” (Adam Masiulanis, personal communication)). This has started to change relatively recently when the company decided that even though the association with White Stork is genuinely positive and has been very successful in terms of creating the company’s image, it is not promising enough in terms of building the brand further. Thus, the main focus has been placed on other activities, such as trainings for key customers and business partners and a trade magazine. Nevertheless, the White Stork has remained a prominent symbol and mascot, widely used in various promotional activities, especially those involving sports and children.
Interestingly, the selection of this species was a pure coincidence and its use has never been backed up with proper market analyses. In the early 1990s, the advertising market in Poland was poorly developed and any original idea had huge chances of becoming a success. Only over time – once the campaign started to bring effects – various commentators have developed deeper meaning for the use of White Stork by Atlas. The species which had first been seen as an impressive crowning of an advertisement pole, became a symbol of the Polish origin of the company, of the good constructor (referring to the storks’ nests), and a source of many other positive emotions and connotations. Clearly, the ecological connotations of White Storks were not considered in this case and the company did not sponsor White Stork conservation projects, except for some incidental instances.
Interestingly, recent survey among construction professionals revealed limited potential to capitalise on this project for conservation purposes (
Although this case study does not represent a nature conservation project, it illustrates the broader social connotations of focal species, and especially the ‘species that sells’ concept (selling commercial products rather than environmental conservation). To some extent, it has become a totemic species for Atlas. Although the company did not reveal willingness to pay for White Stork conservation in this case, this does not preclude other more witty opportunities to capture the hidden potential of capitalising on such corporate practices. Indeed, through its extractive activities, the company negatively influences White Stork habitats, which might provide further arguments to generate funds for White Stork conservation.
Three of our case studies demonstrate the use of White Stork as an umbrella species – at least to some extent. Most prominently, the stork villages (CS2) and the Swedish reintroduction programme (CS3) illustrate how conservation organisations attempt to achieve broader conservation objectives by focusing on a single species. To a lesser degree, in the White Stork and illegal bird hunting in Lebanon (CS1), White Stork served as an umbrella species for other migratory birds – in the sense that it drew attention also to the hunting of other migratory species and the importance of safe migratory routes (interestingly, migratory species are usually not considered good umbrella species [
The social importance of White Stork was the uniting theme in all five case studies, each of which demonstrated strong emphasis on stork images and symbolism. In each of them, White Stork was used as a flagship species that was meant to ‘sell’ broader conservation objectives, attract tourists to bird habitats, or – in CS5 – commercial products. As a charismatic, flagship species, White Stork was able to attract broad attention to the problem of illegal bird hunting in Lebanon (CS1). In all other case study campaigns, White Stork served as a brand for broader objectives. In stork villages (CS2) and the Swedish reintroduction programme (CS3), White Stork is not only branding conservation but also tourism and local development (tourism flagship species). In Germany (CS4), the stork was selected to illustrate the risks that it faces which are not so well-known.
Among our case studies, CS1 most prominently presents White Stork as a social-ecological keystone species, or at least a local flagship species – sensu
Our case studies help to identify the main opportunities and challenges related to the use of various focal species approaches. Only three case studies resonate with our suggested social-ecological perspective (CS1, and to some extent CS2 and CS3), but all five demonstrate both the social and ecological importance of this species to various extents. Additionally, CS2, CS3 and CS5 indicate that the social importance of this species extends beyond environmental conservation. In each case study, White Stork was used as a focal species because storks have positive connotations and attract attention and interest. However, this was not always related to their ecological significance or needs.
Indeed, any social or ecological concept of a focal species alone is not relevant enough from the point of view of broader conservation purposes. There are many border-line cases, making it impossible to distinguish between the social and the ecological within the various terminological distinctions put forward so far. We see the concept of a cultural keystone species as an initial combination of ecological and social, and we propose to extend the understanding and application of this concept to an even more comprehensive social-ecological keystone species. This is in line with the most recent developments of the cultural keystone species “as having essential roles in maintaining any level of complexity within a social–ecological system” (
Scientists increasingly realise the social-ecological context of the world around us. Indeed, the social and the ecological are hardly separable, even if many people still think they are (
So far, the concept of the local flagship species by
Thus, our proposal is that the concept of cultural keystone species should be extended to new spheres: not only indigenous communities but also modern societies who are more indirectly connected to nature, and not only consumption but all forms of human relationships with other species. Furthermore, it should explicitly address the environmental and ecological significance of the species. This in recognition of a commonly occurring situation in which a species is so important for people that the conservation of many other ecosystem components hinges on the protection of this species. In spite of the commonly held view that people are mostly willing to conserve species that are particularly physically attractive – charismatic, totemic etc. – some studies have found that conservation attributes (information on the status of a certain species) may rank even higher in terms of the public’s support for conservation of those species (
Our proposed concept is different from the traditional keystone species, which only reflected ecological importance, and from the flagship species which were only meant to “operate in the public relations and fundraising spheres” (
We see the concept of a social-ecological keystone species as a comprehensive way to depict these complex interactions and interests involved in bringing the different aspects of species prioritisation into a single indicator. A social-ecological keystone species is likely to be more meaningful for broader conservation objectives because it complements the ecological importance with the social perception of a species, thereby opening an opportunity to connect various dimensions of social/cultural value that people attribute to nature to ecological quality and dynamics. The focus on different interactions, not least relations between humans and other species, supports a different worldview where species and nature conservation is not just for nature’s sake but also for our own. The more ways a species, or conservation more broadly, can be linked to people and the values they hold or could cultivate, the more likely it will be that conservation efforts are sustained and successful. The social-ecological keystone species highlights our own role as stewards, with the ultimate target of not only preserving species and ecosystems but also the different avenues for meaningful human interactions with them.
The selection and use of social-ecological keystone species can be aided by cultural creation and branding. The status of a social-ecological keystone species may result from its contribution to the maintenance of selected types of landscapes, which may be culturally important, as in the case of White Stork and rural landscapes in Southern Sweden and Central and Eastern Europe, or – similarly – in Japan in the case of another stork species (
Selection principles matter. They are particularly relevant for engaging with the broader society and in education, and they can help to achieve broader conservation objectives beyond the support for particular conservation projects. For these reasons social-ecological keystone species is also better than the traditional single species approaches, which have been deemed insufficient to ensure the conservation of broader biodiversity (
A limitation might be that for many ecosystems we may not be able to readily find species that would be recognised as socially and ecologically important by modern societies. However, again this provides excellent opportunity for more comprehensive education than in the case of pure flagship species. It maintains the appeal of a flagship species (
Bees constitute another good example, where more and more lay people are concerned about their situation (
To this point,
White Stork provides an important example of a focal species used in different conservation campaigns and in broader social communications, addressing a range of targets. It is most often used because of its social appeal, and while its ecological importance is not similarly spectacular, it is still a valid argument for conservation. This species has a long history of coexistence with humans, and many linkages with specific cultural practices. Hence, White Stork offers an excellent example for discussing the broader social-ecological relevance of species.
Although we do not expect the concept of a social-ecological keystone species to replace the ecological concepts of a focal species, which have their well-established uses in biological and ecological science, we argue that a social-ecological keystone species in principle should be more relevant than a typical social focal species approach (such as flagship species). The added value of a social-ecological keystone species compared to traditional socially-defined focal species approach relates to the higher transparency of the former. A social-ecological approach avoids the specific focus or hidden agendas of specific groups of interested stakeholders who might favour the conservation of certain species over the other, it ensures that these species are relevant to broader social spheres, and it ensures that the selected focal species will indeed help to solve broader environmental problems and will not only serve as conservation mascots. It also demands that that the inherent ecology is easily understood and related to in a way that is meaningful to people.
The social-ecological keystone species concept, where selected species have clear connections to ecological qualities and dynamics can make people (understood as a diverse group of stakeholders) aware that their “preferred” species is a product of ecosystem processes and interactions (and often ecosystems where humans are a dominating force). Thus, conservation projects referring to the idea of a social-ecological keystone species highlight the importance of the connections between the social and the ecological, providing a very good opportunity for ecological education and nurturing a sense of responsibility for nature conservation and additional benefits of biodiversity (
Nevertheless, the social-ecological keystone species is still not likely to solve some important challenges related to previously used concepts of ecological and social focal species. The different focal species concepts are frequently used in an imprecise manner (
In short, a social-ecological keystone species can be used in practice to define conservation objectives and to further ecological education, showing how people and the environment are interlinked through selected relatively easily recognised species. It can be used as part of broader systems of indicators used for environmental management that incorporate social and ecological contexts to “evaluate the state of cultural wellbeing associated with different ecosystems and address the conditions which threaten or enable these conditions to thrive” (
