Abstract

A key issue in conservation biology is recognizing and bridging the gap between scientific results and specific action. We examine sea turtles—charismatic yet endangered flagship species—in the Mediterranean, a sea with historically high levels of exploitation and 22 coastal nations. We take sea turtle rescue facilities as a visible measure for implemented conservation action. Our study yielded 34 confirmed sea turtle rescue centers, 8 first-aid stations, and 7 informal rescue institutions currently in operation. Juxtaposing these facilities to known sea turtle distribution and threat hotspots reveals a clear disconnect. Only 14 of the 22 coastal countries had centers, with clear gaps in the Middle East and Africa. Moreover, the information flow between centers is apparently limited. The populations of the two species nesting in the Mediterranean, the loggerhead Caretta caretta and the green turtle Chelonia mydas, are far below historical levels and face a range of anthropogenic threats at sea and on land. Sea turtle rescue centers are acknowledged to reduce mortality in bycatch hotspots, provide a wealth of scientific data, and raise public awareness. The proposal for a Mediterranean-wide rescue network as published by the Regional Activity Centre for Specially Protected Areas a decade ago has not materialized in its envisioned scope. We discuss the efficiency, gaps, and needs for a rescue network and call for establishing additional rescue centers and an accompanying common online database to connect existing centers. This would provide better information on the number and types of rescue facilities on a Mediterranean scale, improve communication between these facilities, enhance standardization of procedures, yield large-scale data on the number of treated turtles and their injuries, and thus provide valuable input for targeted conservation measures.

Introduction

Conservation biology is called upon to help translate scientific knowledge into specific action. Bridging this gap has been abetted by a new era of scientific endeavor (Stachowitsch 2003, Rose et al. 2011) in which the focus and urgency of scientific work has changed. In marine biology, a considerable and increasing percentage of papers is being devoted to documenting deterioration and dysfunction at population, ecosystem and global levels, often suggesting amelioration strategies. This is particularly true in the case of sea turtles, well-known flagship species, which face major anthropogenic threats at sea and on their nesting beaches worldwide. The complex life-history and highly migratory nature of sea turtles (Hamann et al. 2010), combined with the many human impacts, make conservation challenging and transcend simple, contained management measures. All sea turtle species are listed on The IUCN Red List of Threatened Species (IUCN 2014). They are a case study of marine megafauna that are now functionally or entirely extinct in many coastal ecosystems (Jackson et al. 2001).

The Mediterranean is a historically overexploited marginal sea (Morales-Muñiz and Roselló-Izquierdo 2008). It is also polluted, for example with oil and plastic, which are particularly pertinent with regard to sea turtles (Gramentz 1988). Its multitude of coastal nations with different socio-economic and cultural backgrounds—not to mention linguistic barriers—stymies the concerted protection and conservation of its sea turtle populations (Amano and Sutherland 2013). The loggerhead Caretta caretta (Linnaeus, 1758) is the most common species in the Mediterranean (Broderick et al. 2002, Margaritoulis et al. 2003). Like the green turtle Chelonia mydas (Linnaeus, 1758), it nests in the eastern regions (Kasparek et al. 2001, Margaritoulis et al. 2003), but also frequents different habitats during different life stages in the western sector (Garofalo et al. 2013), where it co-occurs with individuals from the Atlantic (Carreras et al. 2006, Casale et al. 2008a, Wallace et al. 2010). Leatherbacks Dermochelys coriacea (Vandelli, 1761) are observed regularly at sea (Casale et al. 2003), whereas the hawksbill turtle Eretmochelys imbricata (Linnaeus, 1766) and Kemp’s ridley Lepidochelys kempii (Garman, 1880) are recorded here only occasionally (Laurent and Lescure 1994, Camiñas 2003). Sea turtles have been afforded protection under a number of treaties and laws (Suppl. material 1). The EU Habitats Directive lists all five species in Annex IV as being of community interest and in need of strict protection (European Community 1992). It also protects the loggerhead and green turtle as priority species with the need for special conservation areas (Annex II). Accordingly, these two species are subject to wide-ranging scientific research, monitoring, and conservation efforts by dozens of universities and institutions, along with numerous dedicated associations and societies, e.g., ARCHELON, EuroTurtle, MEDASSET.

Fisheries bycatch, boat strikes, intentional killing, and entanglement in marine debris including ghost gear have been identified as the main threats at sea (Tomás et al. 2008, Casale and Margaritoulis 2010, Casale et al. 2010, Casale 2011). On land, degradation and reduction of nesting habitat caused by touristic and recreational activities, light pollution, noise, construction, sand extraction, and traffic (Camiñas 2004) are taking their toll. Turkey, for example, holds the largest green turtle nesting population in the Mediterranean with about 230 females nesting annually (Seminoff 2004). Only three generations back, from 1879–1919, about 3,500 individuals still nested there (Seminoff 2004). The Turkish population has experienced a 93% decline over the last 95 years. Green turtles face a measurable risk of extinction worldwide and therefore qualify for the IUCN Endangered status under Criteria A2bd (Seminoff 2004). The Mediterranean population is genetically distinct from Atlantic populations and belongs to a separate regional management unit (RMU) (Wallace et al. 2010), which is recognized to face high threats and a high risk of extinction (Wallace et al. 2011). A total of 339–369 females are nesting in the entire Mediterranean (Broderick et al. 2002).

The resident Mediterranean loggerhead population is genetically isolated (Carreras et al. 2011) from individuals of the two Atlantic RMUs migrating to Mediterranean foraging grounds and is considered to face high threats (Wallace et al. 2011). Bycatch rates are estimated at up to 200,000 loggerheads per year, leading to more than 50,000 deaths annually through direct interaction alone (Casale 2008, Lucchetti and Sala 2010, Casale 2011). Considerable declines on specific nesting beaches have been recorded (Ilgaz et al. 2007). Overall, no significant population trend could be observed on nesting beaches over the last decades, but survival probabilities are somewhat lower than would be expected from a healthy population (Casale et al. 2014). Anecdotal information suggests a decline over decadal scales (Casale and Margaritoulis 2010). The latest IUCN assessment classified the loggerhead as vulnerable (Marine Turtle Specialist Group 1996) but did not specifically deal with the Mediterranean population and needs updating (IUCN 2014). Total population estimates are not available, neither are total stock mortality estimates (Camiñas 2004).

The importance of dedicated rescue facilities for sea turtles was recognized during the 1980s (RAC/SPA 2004). One of the first rescue centers in the Mediterranean was established by ARCHELON in Greece in 1994 (Suppl. material 1). Others followed, but not all of them provided full facilities and treatment (Bentivegna 2005). After two decades of ill-concerted development, the need for regulating and improving sea turtle rescue was generally acknowledged, and guidelines for the standardization of rescue activities were established. The Regional Activity Centre for Specially Protected Areas (RAC/SPA) published a rough outline of a Mediterranean-wide sea turtle rescue network. It should consist of sea turtle rescue centers and first-aid stations (hereafter referred to as STRCs and FASTs, respectively) strategically based along the coasts, each adhering to common established guidelines of conduct (RAC/SPA 2004). RAC/SPA proposed to potentially act as the network’s international coordinator (see Suppl. material 1 for more details).

The most obvious function of STRCs and FASTs is the rescue and rehabilitation of individual turtles. STRCs, though “in the last line of defense”, are a management tool that acts on a number of fronts. Firstly, they help increase adult and subadult survival rates, a major priority in conservation action (Camiñas 2004) that has a considerable effect at the population level. STRCs play a significant role in reducing indirect mortality of stranded, injured or comatose adults, and large juveniles. These are size classes typically affected by the two major threats at sea: bycatch and ship strikes. Adult survival is the main factor in population growth rates; large juveniles have a high reproductive value (Wallace et al. 2008). Modeling approaches show that population persistence is much more sensitive to the survival of older age classes than to that of the first year cohort, i.e., eggs and hatchlings (Chaloupka 2002, Mazaris et al. 2005, Mazaris et al. 2006). Secondly, research is an acknowledged function of STRCs (RAC/SPA 2004). STRCs are often linked to stranding network activities. They provide a wealth of scientific data (Shaver and Teas 1999, Casale et al. 2010) on each stranded or floating turtle, including the nature of their injuries. Stranding records represent a valuable source of information on both mortality factors and spatio-temporal distribution (Casale et al. 2010). Thirdly, awareness campaigns targeting fishers to reduce post-release mortality of bycaught turtles are an urgent priority mitigation measure (Casale et al. 2007a, Echwikhi et al. 2012, Domènech et al. 2014). RAC/SPA (2004) acknowledged the importance of STRCs in sensitizing fishers to the plight of sea turtles through awareness programs, handling workshops, and promoted cooperation between fishers and conservation biologists. Thusly trained fishers are more likely to bring in comatose turtles for medical treatment before releasing them back into the sea (Casale et al. 2007a, Domènech et al. 2014). They are also more likely to adopt the simple onboard handling procedures (Gerosa and Aureggi 2001) that can considerably reduce indirect mortality of bycaught turtles. Fourthly, public awareness campaigns also target non-professionals, who may visit STRCs and partake in educational activities or volunteer. STRCs therefore bridge the gap between science and everyday life. They can get people involved in the conservation cause and potentially initiate a public conservation movement (Casale et al. 2007a).

Despite these efforts, clear gaps remain in the protection of Mediterranean sea turtles. In trawl fisheries, for example, proven management strategies such as turtle excluder devices (TEDs) are not routinely employed (Laurent et al. 1996, Casale et al. 2004), but their future use in EU waters is currently being discussed. Outdated fishing gear is apparently sold to non-EU countries, perpetuating illegal fishing practices in both larger-scale and artisanal fisheries (Lucchetti and Sala 2010). Bycatch in the latter, small-scale fisheries can even exceed levels in industrial fisheries (Lewison et al. 2014) and is particularly relevant in the Mediterranean (Echwikhi et al. 2012). This adds to the urgency of a functioning and tight-knit rescue network and supraregional awareness programs.

We take the number of rescue facilities as a visible measure for practical progress in sea turtle conservation and provide an update on currently operating facilities (STRCs, FASTs, informal or temporary institutions) with verified contact details and information on the history of each center (Table 1). We then examine whether the coverage of rescue facilities correlates with threat hotspots and the distribution, including nesting sites, of the two sea turtle species nesting in the Mediterranean, and whether the number of facilities seems adequate. We take fisheries bycatch—the most important source of anthropogenic sea turtle mortality at sea—as a proxy for threats (Lutcavage et al. 1997, Casale 2008, Casale 2011).

Methods

Sea turtle rescue facilities currently in operation in the Mediterranean

Kasparek’s (2001) and RAC/SPA’s (2004) earlier lists of STRCs served as a starting point for our compilation. Casale and Margaritoulis (2010) and RAC/SPA’s List of Focal Points for SPAs provided useful information on potential contact persons and their email addresses. We searched for Mediterranean rescue facilities (STRCs and FASTs) on the internet between August 2012 and March 2014 using Google Search and Duck Duck Go. Searching for phrases such as “list of Mediterranean sea turtle rescue centers”, “first aid stations for marine turtles”, “sea turtle rescue”, and respective variants in English, French, Italian, and Spanish yielded abundant information. Much, however, was incomplete, outdated, and difficult to substantiate, i.e., gray literature, websites without “date of latest update”, or PDFs without mastheads.

The next step involved obtaining full contact details by sending inquiries directly to the centers. When basic contact information was lacking or no data were available for a particular country, we sent inquiries to official institutions, i.e., ministries of the environment, animal welfare organizations, universities, and national park administrations. We also asked the rescue center contacts about other facilities in their vicinity.

Sea turtle distribution, threat hotspots, and coverage with rescue facilities

We reviewed the peer-reviewed literature to identify the key distribution areas, i.e., nesting beaches, feeding and overwintering areas, foraging sites of juveniles, and major migration corridors, of loggerhead and green turtles.

We also reviewed the peer-reviewed literature to identify threat hotspots for sea turtles in the Mediterranean. Of the commonly acknowledged main threats, i.e., nesting habitat degradation, bycatch, ship strikes, and direct exploitation, we chose fisheries bycatch as a proxy for threats because: 1) it affects primarily older individuals and has great impact on population levels; 2) bycatch and its geographic distribution are quantifiable; 3) it occurs Mediterranean-wide and year-round; 4) its effects can be mitigated by STRCs. We briefly discuss the main deployment areas of the three critical fishing gear types, i.e., trawl, drifting longline, set nets (Lucchetti and Sala 2010).

To better visualize the geographic coverage of rescue facilities and its appropriateness, we compare current locations of rescue facilities to 1) key sea turtle distribution areas (Fig. 1), 2) bycatch hotspots in the three crucial gear types (Fig. 2), and 3) RAC/SPA’s (2004) proposed rescue network (Fig. 2).

Results and review of current status

Sea turtle rescue facilities currently in operation in the Mediterranean

The literature and internet search for rescue facilities yielded 34 STRCs, eight FASTs, and seven informal or temporary rescue institutions (Table 1, Figs 12). Based on website content and personal communications, we assumed that the listed STRCs and FASTs adhere to RAC/SPA’s code of conduct.

Italy held 21 STRCs, six FASTs, and one informal rescue facility. Spain had three STRCs, Croatia and Greece each had two STRCs, the latter also featuring two FASTs. France held one STRC and a local rescue network in Corsica. Cyprus, Israel, Monaco, Tunisia, and Turkey held one STRC each. Malta held a temporary rehabilitation center. While Egypt, Gibraltar, Morocco, and Slovenia did not have any formal rescue facilities, injured turtles were cared for by veterinarians, local animal welfare organizations and rescue associations. Albania, Bosnia and Herzegovina, Montenegro, Northern Cyprus, and Syria had no facilities. Data for Libya were available but could not be verified. For Algeria, Lebanon, and the State of Palestine, no data on rescue facilities were found and no official institutions reached.

Sea turtle distribution

Ninety-nine percent of green turtle nesting takes place in Turkey and Cyprus (Kasparek et al. 2001) (Fig. 1). The five most important nesting beaches are located in the east of Turkey close to Syria, and on the northern coast of Cyprus. Minor nesting activity also occurs in Syria, Lebanon, Israel, and Egypt (Camiñas 2004, Rees et al. 2008, Stokes et al. 2015) (Fig. 1). Pelagic developmental and neritic habitats were commonly thought to be restricted to the eastern Mediterranean (Levant basin) (Camiñas 2004). Recently, satellite-tagged individuals revealed an important migratory corridor from Turkey and Cyprus to Egypt and Libya, with two major foraging hotspots in the latter country (Stokes et al. 2015).

Loggerhead reproductive habitats and main foraging grounds are concentrated in the wider eastern basin (Casale and Margaritoulis 2010) (Fig. 1). Main nesting sites are located in Greece, Turkey, Cyprus, and Libya but nesting also occurs in Tunisia, Israel, Syria, Lebanon, Italy (Mingozzi et al. 2007), and Egypt (Margaritoulis et al. 2003, Camiñas 2004) (Fig. 1). Loggerheads frequent different habitats during different life stages. As juveniles grow, they are increasingly found in neritic habitats, switching from epipelagic prey caught in oceanic areas to benthic prey (Schroeder et al. 2003, Casale et al. 2008b). Adults show extended fidelity to their neritic feeding grounds (Broderick et al. 2007). Individuals of the Mediterranean RMU (Wallace et al. 2010) range throughout the basin; Atlantic transients visit foraging habitats in the western Mediterranean.

Continental shelves and slopes constitute the main adult loggerhead feeding areas (Fig. 1). The northern Adriatic is an important foraging area (Casale et al. 2010) for adults from Greek (Lazar et al. 2004, Carreras et al. 2006, Giovannotti et al. 2010, Garofalo et al. 2013) and Turkish rookeries, as well as for juveniles (Casale et al. 2004). Other important areas are the southern Adriatic (Casale et al. 2012a), the Ionian Sea, the Strait of Sicily, and the Tunisian shelf (Margaritoulis et al. 2003, Casale et al. 2007b, Casale et al. 2014). The latter is frequented by turtles from Greek rookeries, Libya, and the Atlantic (Garofalo et al. 2013).

In the central Mediterranean between Italy, Tunisia, and Libya, potential neritic and pelagic foraging habitats are close to each other (Casale et al. 2008b) (Fig. 1). The Pelagie Islands, for example, are a core foraging ground here (Casale et al. 2012b). Individuals from the key Mediterranean turtle rookeries, i.e., western Greece, Crete, and Cyprus, frequent these central Mediterranean feeding grounds (Margaritoulis et al. 2003, Broderick et al. 2007, Casale et al. 2008a, Zbinden et al. 2008). Other important neritic foraging areas are off southeastern Turkey, the Egyptian coast (Gerosa and Casale 1999), and the Spanish coast (Gómez de Segura et al. 2006).

The Gulf of Gabès (Tunisia, Libya) and the northern Adriatic with their wide shelves are also well-known resting and wintering areas (Camiñas 2004) (Fig. 1). Moreover, the southern Adriatic and to a lesser extent the northern Adriatic and Ionian sea are important developmental areas for loggerheads in the first four years of their lives (Casale et al. 2009). Preferred loggerhead habitats off the Spanish Mediterranean coast are characterized by a large number of juveniles, especially around the Balearic islands during spring and summer (Camiñas and de la Serna 1995) and around Columbretes Island Marine Reserve throughout the year (Gómez de Segura et al. 2003).

The North African coast is apparently an important migratory pathway for loggerheads across the Mediterranean (Broderick et al. 2007, Casale et al. 2012b). Seasonal movements include southbound emigration movements from the northern Adriatic (Lazar et al. 2003, Zbinden et al. 2008, Zbinden et al. 2011) and movements of juveniles in the western Mediterranean (Cardona et al. 2009). The central Mediterranean, in particular the Strait of Sicily, is probably a key route for turtles migrating between the eastern and the western Mediterranean basins (Casale et al. 2007a).

Threat hotspots (fisheries bycatch)

Casale (2008) estimated the incidental captures of Mediterranean sea turtles by fishing gear at 150,000 per year and the associated mortality at 50,000. The respective values in a more recent analysis remained in the same high range, namely 132,000 and 44,000 (Casale 2011). Camiñas (2004) identified the Spanish and Italian surface longline fisheries, northern Adriatic Italian trawl, Tunisian trawl, Turkish trawl, Moroccan driftnet, and Italian driftnet fisheries as having the highest impact (Fig. 2). The Adriatic and Ionian Seas and the Strait of Sicily show high bycatches by trawlers (Casale et al. 2004, 2007a) and longliners (Deflorio et al. 2005, Casale et al. 2007a) (Fig. 2). The central Mediterranean was recognized as a bycatch hotspot of pelagic longline and bottom trawl fisheries (Jribi et al. 2007, 2008, Casale et al. 2007a, Echwikhi et al. 2010, 2012; Fig. 2). Artisanal fisheries are the most important in terms of numbers of boats and fishermen involved (Camiñas 2004, Cambiè 2011). Accordingly, Casale (2011) identified small-scale fisheries (versus large vessels) as a key concern and pinpointed the eastern basin as a hotspot.

Discussion

Nature conservation and species protection have developed in direct response to the deterioration of many habitats and the decline of many species. Nonetheless, there is a continuing gap between problem recognition in the form of scientific data and specific management actions. Moreover, the process is typically reactive rather than proactive. We proffer that this gap should be the narrowest for endangered flagship species in habitats that are well-defined and have a long history of scientific research. Sea turtles in the Mediterranean are a case in point. Just as the analysis of sea turtle protection coverage (based on nesting sites) revealed clear gaps on a global level (Mazaris et al. 2014), our review (based on rescue center coverage) revealed clear gaps on the Mediterranean level as well.

Compared to the international conventions and protocols of the 1970s that first recognized the problems facing sea turtles in the Mediterranean, most STRCs and FASTs were founded quite late (Suppl. material 1). Moreover, the quality criteria for these facilities were formulated even later (RAC/SPA 2004).

Compared to Kasparek’s (2001) and RAC/SPA’s (2004) preliminary lists of about a dozen rescue centers, the number of known rescue facilities in the Mediterranean has quadrupled within the last ten years. With nearly 50 facilities today (Figs 12), the dimension of RAC/SPA’s (2004) proposed rescue network has now been reached. Nonetheless, there are major differences between the proposed network and the current situation, specifically in type and distribution.

Regarding type, RAC/SPA envisaged a network consisting of 16 rescue centers, each connected to between two and four emergency centers (Fig. 2). Currently, however, there are about four times as many STRCs as FASTs. The original proposal might have been based on more FASTs as a more cost-effective solution. One potential explanation for the current proportion, though, is that FASTs proved to be suboptimal because most injured turtles require long-term veterinary treatment in a rescue center. Alternatively, our web-based search might have missed FASTs because they probably have smaller budgets and are less well represented on the internet. This is an invitation to complete and regularly update our list of Mediterranean sea turtle rescue facilities.

Regarding distribution, RAC/SPA’s (2004) proposal for an even spread along the Mediterranean coasts has not been realized. For example, whereas the original proposal indicated 17 facilities along the southern Mediterranean coastline (5 STRCs, 12 FASTs), only 3 are currently confirmed. The distribution along the northern coast more closely resembles RAC/SPA’s proposal. Once Albania’s planned STRC (Table 1) is in effect, the same will hold true for the eastern Adriatic. Nonetheless, some regions (Italy) exhibit numerous closely adjoining STRCs, while others have long stretches without a single facility.

More than half (28) of all facilities are concentrated in Italy. This is the best fit because the total estimated bycatch there (23,600 = 18%; Casale 2011) is the highest of any Mediterranean country. Spain, with the second highest bycatch (20,920 = 16%) is covered by only 3 facilities. Nonetheless, Spain shows the best agreement in facility number and location with RAC/SPA’s proposal (Fig. 2). The third, fourth and fifth highest bycatches are reported for Tunisia (17,600 = 13%), Morocco (15,400 = 12%), and Turkey (12,900 = 10%). Here the correlation is extremely poor, each country having only a single facility. This is particularly evident in the case of Turkey, which hosts many key nesting beaches but has only one very recently established STRC. Overall, there is a pronounced shortage of facilities along the Middle East and African Mediterranean coasts, especially when considering that Casale (2011) identified the North African continental shelves, the Levantine basin and the Aegean Sea as the areas in which sea turtles were most at risk from bottom trawling, demersal longlines, and set nets.

The deficits in STRC numbers and distribution no doubt partially reflect the different cultures, socio-economic status, funding priorities and perception of environmental issues of the 22 Mediterranean countries. It is further compounded by security issues in many countries (Amano and Sutherland 2013). Along with language barriers, these factors are also a hindrance to the originally envisioned concept of a functioning network. In many cases there seems to be limited knowledge about and communication between neighboring centers—within and across borders. This was detected at the national level, e.g., in the 15 Italian administrative regions with access to the sea, and even at local level, i.e., two facilities in one town. Clearly, knowledge of neighboring institutions and communication between centers are key ingredients for successful collaboration on the national level, which in turn is a prerequisite for rewarding international cooperation.

What are the repercussions for the current status of Mediterranean sea turtles? Primarily, suboptimal species protection. Injured individuals with chances of survival are not being detected and not receiving the necessary veterinary care. Each adult turtle is thought to represent one surviving individual out of an estimated 500–1000 hatchlings that emerge from their nests on the beach. This, coupled with the life history of sea turtles—slow growth, long period before sexual maturity—means that every adult is very important. Considering the historical decline in sea turtle numbers and the present low numbers, the mortalities must be reduced. We must avoid the situation—known for cetaceans such as the vaquita in the Gulf of California, the Western Pacific gray whale, or the North Atlantic right whale—that further human-induced mortalities of any individual, in particular adult females, will jeopardize species or population survival (Kraus et al. 2005). This is precisely where the role of STRCs grasps: every rescued individual counts.

What is the vision for the future and how can this be achieved? The goal must be to work toward a dense and evenly distributed rescue facility network. Communication between centers must be improved. This will not only help rescue individual sea turtles but will provide added benefits—in a positive feedback loop—for the other STRC functions, namely research and public outreach (RAC/SPA 2004). What species and life stages are being treated and what injuries are being suffered in what regions? The actual overall numbers of treated and saved individuals—related to the number of nesting females—is the first important data set that STRCs could deliver. STRCs are eminently suited to provide answers, which are currently not available and which are not necessarily supplied by today’s hypothesis-driven scientific literature (Casale and Margaritoulis 2010). Such information, compiled Mediterranean-wide and collated by a coordinating level, can then be translated into improved management. The relatively small size of the Mediterranean may actually help in collecting such information: many critical areas are located within Exclusive Economic Zones, simplifying data collection and promoting a sense of responsibility.

Such data could best be compiled using a common online database. This is a viable option based on our experience at the level of individual STRCs: most contacted rescue center staff were readily willing to help, seemed interested in information dissemination, and eager for news about other facilities. We therefore support setting up a “Mediterranean Sea Turtle Rescue Network Database” online, containing and updating all the basic information on rescue facilities (Table 1). The idea of an internet gate or special webpage for communication, containing publicly available profiles of existing rescue facilities, is not new (Kasparek 2003, Panagopoulou and Rees 2009, also see Suppl. material 1). The online database could be hosted by recognized pan-Mediterranean institutions, e.g., RAC/SPA or EuroTurtle, ensuring a wide audience from the onset. It would be an inexpensive yet effective tool for adequate coordination and monitoring of rescue and conservation efforts. Beyond facilitating communication among sea turtle specialists, marine scientists and non-professionals, it would help standardize data collection and presentation.

General conclusions

Our review shows that sea turtle rescue facilities—as visible and measureable evidence of concrete conservation action—are characterized by a:

  1. relatively late start in light of early conventions and protocols addressing sea turtle threats,

  2. relatively late set of quality criteria,

  3. slow increase in number,

  4. patchy distribution with major unserviced regions,

  5. often haphazard rather than problem-oriented correlation between sea turtle distribution/threat hotspots and rescue facility sites,

  6. still insufficient number,

  7. poor readily available information on and suboptimal communication between these facilities.

Information on the number of treated turtles and their injuries is essential input for further, well-targeted, and concerted conservation measures. At the same time, we must go beyond the often heard call for more data and apply common sense to the ongoing threatened status of sea turtles in the Mediterranean and elsewhere. Further action should not be delayed until further evidence has been collected. A functioning network of sea turtle rescue centers would be a good first step in this direction.

Acknowledgements

We would like to thank all those persons—many of whom are mentioned in Table 1—who took the time to respond to our inquiries about their facilities. Sabine Gasper-Mautes patiently and professionally produced the many iterations of Figs 1 and 2. Two reviewers provided substantial input that helped improve this manuscript. Our engagement with sea turtle issues in the Mediterranean would not be possible without the long-term support by TUI Austria, The Society of the Friends of Schoenbrunn Zoo, and the Blauer Kreis.
