6 01. GENERAL INTRODUCTION Marcos A M Pereira 1, Eduardo J S Videira 1 & Cristina M M Louro 2 1 AICM, Maputo. marcospereira@gmx.net; pipocas99@yahoo.com; 2 CTV, Maputo. cristinammlouro@gmail.com All seven species of marine turtles are threatened with extinction and protected internationally for decades. However, and despite diverse conservation efforts, marine turtle populations continue to decline. Several anthropogenic and natural factors contribute to this decline, being the most important the incidental captures and mortality by different fisheries, turtle meat and egg consumption by humans, use of the shell for ornamental purposes, nest destruction by coastal erosion and habitat loss. Of the seven species, five occur and nest along the Mozambican coast where marine turtles are protected by law since 1965 (Hughes, 1971). The current legal framework is sufficient and foresees adequate fines and penalizations for the protection of marine turtles. However, the implementation and efficiency of the legislation is practically non-existent (Louro et al., 2006). On the other hand, effective monitoring, research and conservation measures and activities are relatively recent and in a reduced number, considering the size of the coastline. Consequently, very few studies were conducted and there is a poor knowledge on basic aspects of the ecology and conservation status of these animals. The present report, aims at providing quantitative information on nesting, tagging and mortality of marine turtles in Mozambique in the 2007/08 season. Additionally, historical data from previous seasons was compiled. The data used were gathered from literature searches, interviews and direct collection in the field (please see Methodology and Sampling Effort section on each chapter). A total of 13 areas, where monitoring, tagging or conservation projects /and or data exists were included (each presented separately). The dada is presented in table form for easy comprehension and interpretation. These, however, must be interpreted and à posteriori with caution. The data presented was extracted as is from the available source, and in several cases there were errors in the data series. References Hughes, G. (1971).

CTV, Maputo. cristinammlouro@gmail.com Angie Gullan angie@dolphin-encountours.co.za Sources: Lombard & Kyle (2004, 2005) Introduction Conservation, monitoring and research programs on loggerhead (Caretta caretta) and leatherback turtles (Dermochelys coriacea) initiated in this area after the civil war. During the period from 194 to 1996 a program was implemented with the aim of monitoring nesting females and promote awareness of local communities and tourists with regards to the value of marine turtles (Lombard & Kyle 2004, 2005). In the 2005/06 season, Chacate et al. (2006), monitored females and nests. As part of the Lubombo Transfrontier Conservation initiative, the Dolphin Care Africa Turtle Project initiated in the 2007/08 season. Methodology and Sampling Effort The program conducted in 1994/06 covered the stretch of coast from 3 km south of Ponta Malongane to Ponta Milibangala. For the purposes of this chapter, only the data collected within 3 km south of Malongane were considered. The monitoring was done throughout December, which represents the peak of nesting activity in the area. Patrols were done by car every night (Lombard & Kyle 2004, 2005). The techniques and tagging materials used followed and were supplied by the Ezemvelo Kwazulu-Natal Wildlife, South Africa. The 2007/08 monitoring covered approximately 8 km, between the border with South Africa and Ponta Malongane, and was carried out between November and 2007 and March Patrols were done daily, at night and dawn, for aproximately 4-5 hours. Two permanent monitors and one to three volunteers constituted the team and walked from north to south. The following data was collected: i) species identification; ii) new/old crawl; iii) presence/absence of tags; iv) Nest/no nest; v) number of eggs laid; and vi) nest location (coordinates). During this season, the titanium tags used were supplied by the Mozambique Marine Turtle Tagging Program and had the following codes MO926 MO949. 2

12 03. PONTA MALONGANE PONTA DOBELA Compilation: Contributors: Marcos A M Pereira, AICM, Maputo. marcospereira@gmx.net Pierre Lombard & Stephan Lombard mankwe@info.bw Sources: Kyle & Lombard (1996, 2004, 2007); Lombard (1997, 2005, 2008); Magane & João (2002) Introduction Four species of marine turtles occur in this area of which, only two, the loggerhead (Caretta caretta) and leatherback (Dermochelys coriacea), nest while the green turtle (Chelonia mydas) and the hawksbill (Eretmochelys imbricata) are common in the adjacent waters and subtidal reefs (Hughes, 1971; Tinley, 1971; Magane & João, 2002; Louro et al., 2006). The coastline between Ponta Malongane and Ponta Dobela has one of the best data series regarding monitoring tagging of marine turtles in the country. Under the initiative of Mr. Pierre Lombard, the monitoring program initiated in the 1994/95 season and has been carried out systematically and uninterruptedly ever since. Another program, based at the Maputo Special Reserve (MSR), incorporated this stretch of coastline (Matonde - Ponta Dobela), in the 1996/97 to 2000/01 seasons (Magane & João, 2002). Methodology and Sampling Effort Mr. Lombard s monitoring has been following the same procedure throughout the years. Night patrols are conducted from Ponta Malongane to Ponta Dobela, and sometimes further north. Due to logistical constraints the monitoring period was adjusted to the turtles highest nesting activity, generally from early December to mid January. When a turtle is found it is identified, measured and tagged if no tag is present. Metadata like data/time, location (distance in km from Ponta Malongane) and nest/no nest are also collected. The data presented in this chapter was gathered from several reports prepared for each season (see Sources). Therefore, data for some seasons were not available, thus is not presented. The monitoring program coordinated from the MSR, established three monitoring camps (see chapter 5. Ponta Dobela Ponta Chemucane). At each camp, two members of the community conducted daily patrols (one at night and one at dawn) were nests were registered and the tracks erased. Five areas were considered. For the present chapter, only the southern area is relevant: Matonde Dobela. From this program s data, only the number of nests laid in the 1999/2000 and 2000/01 seasons was used. 7

AICM, Maputo. pipocas99@yahoo.com Contributors: Matthew Prophet 1 & Lina Buque matproph@gmail.com Sources: Magane & João (2000, 2002); Costa et al. (2007) Introduction Two species of marine turtles nest between Ponta Dobela and Ponta Chemucane, close to the Maputo Special Reserve (MSR); the loggerhead (Caretta caretta) and leatherback (Dermochelys coriacea; Tello, 1973; Magane & João, 2002; Costa et al., 2007). Beside these two species, according to Hughes (1971), Louro et al. (2006) and Costa et al. (2007), two other species occur in the adjacent waters; the green (Chelonia mydas) and hawksbill turtles (Eretmochelys imbricata). Magane & João (2002) reported that the nesting season in this area runs from October to February, with a peak between November and January. Monitoring in this area initiated in the 1996/97 season and was conducted uninterruptedly until the 2000/01 season (Magane & João, 2002). After a long break only one monitoring and tagging event was conducted in the 2004/05 season (Costa et al., 2007). In the last season (2007/08), a monitoring and tagging program was conducted in the area covering about 5 km to the north and 5 km to the south of Ponta Milibangalala. Methodology and Sampling Effort For the compilation of this chapter, information presented by Magane & João (2000, 2002), Costa et al. (2007) and the data collected in monitoring of the 2007/08 season were used. Magane & João (2000, 2002) covered a total of 25 km, from Ponta Chemucane to Ponta Dobela. Three monitoring camps were established at Ponta Membene, Milibangalala and Dobela, were two monitors per camp were based. These were recruited from the community. Patrols were conducted on foot, twice a day: at dawn and at night (1 hour before high tide). Nests were registered and tracks erased to avoid double counting and theft. This program was carried out from 1996/97 to 2000/01, and run from October to February. In the 1996/97 and 1998/99 seasons, the data collected were relative to the number of nests without differentiation into species, month or areas. These parameters were only collected in the 1999/2000 and 2000/01 seasons. For the purposes of this chapter, only data collected from Ponta Chemucane to Ponta Dobela (about 18 km) were used. 12

18 In the 2007/08 season, four monitors from the community were trained and collected the data. Patrols were done on foot from Ponta Milibangalala either to the north or south (covering about 10 km). From January 2008, only two monitors patrolled the area. The following data were collected: number of tracks, nest/no nest, date, species (identified from the specimen or from the track whenever possible), presence of tags and morphometrics. When possible turtles were tagged. Additionally, the number of eggs hatched and un-hatched, live and dead hatchlings and hatching date were also noted. Vehicle patrols were done on three occasions, November and 1 December 2007 from Matonde to Ponta Abril. For the present chapter, only data collected between Ponta Dobela and Ponta Chemucane were used.

AICM, Maputo. pipocas99@yahoo.com Contributors: Earl Strydom 1 & Matthew Prophet bergstromconstruction@yahoo.com 2 matproph@gmail.com Introduction Nesting information from the coastline between Ponta Chemucane and Santa Maria is scarce, as no studies or monitoring programs have been conducted in the area. Give thr proximity of this are to the Maputo Special Reserve (MSR) and Inhaca Island, it is believed that two species nest on its beaches, the loggerhead (Caretta caretta) and leatherback turtles (Dermochelys coriacea; Hughes, 1971; Tello, 1973; Tärnlund, 1999; Ng, 2001; Magane & João, 2002). Additionally, two other species may occur in the adjacent waters, the green turtle (Chelonia mydas) and hawksbill (Eretmochelys imbricata; Hughes, 1971; Louro et al., 2006; Costa et al., 2007). The nesting season should also run from October to February, as reported for the whole southern Mozambique region (Hughes, 1971; Tarnlund, 1999; Ng, 2001; Magane & João, 2002; Louro et al., 2006). In the last season (2007/08), a monitoring program was initiated. Based in Santa Maria and covering about 10 km south. Green turtle (Chelonia mydas) near the shore.

24 Methodology and Sampling Effort The monitoring was coordinated by Mr. Earl Strydom and carried out by its tourism operation staff, based in Santa Maria. These were previously trained in a course held at Ponta Milibangalala in October Mr. Strydom and his collaborators (about 9 in total) patrolled the area on foot (sometimes on quad bikes), covering about 10 km. A vehicle patrol was conducted from Matonde to Ponta Abril on November and 1 December From the data colleted in the vehicle patrol, only data from Ponta Chemucane to Ponta Abril, were incorporated in the present chapter (about 30 km). The following data were colleted during the patrols: number of tracks, nest occurrence, date of nesting, species (the identification was done on the specimen on the beach or using the tracks whenever possible), presence of tags and morphometric data. Tagging was not conducted in this area, nor hatching control or egg/hatchlings monitoring. Results Table 5.1.

Regular monitoring initiated in the 1988/89 season (Tärnlund, 1999), although studies on marine turtles initiated long before (Hughes, 1971; Tinley, 1971). Hughes (1971), Macnae & Kalk (1969) and Kalk (1995) reported the occurrence of four species in the surrounding waters, namely the green turtle (Chelonia mydas), hawksbill (Eretmochelys imbricata), leatherback (Dermochelys coriacea) and loggerhead (Caretta caretta). However, only two species nest on Inhaca and Portuguese islands: the loggerhead and leatherback turtles. Marcos A M Pereira Loggerhead turtle (Caretta caretta), observed at Baixo Danae. Inhaca Island, January Photo: Marcos A M Pereira. 22

28 Methodology and Sampling Effort The available data spans from the 1988/89 to the 2007/08 seasons, excepting the 1994/95 where no data was collected. A reserve ranger (Mr. Raimundo Sambo) walks, during the nesting season (usually between September/October until March), the eastern coast of the island, from Ponta Torres to the lighthouse (about 12 km) on a daily basis starting at 04:00 h. Turtles are identified through direct observation of the females or by the tracks and the location of the nest is dissimulated. Nests are monitored and upon hatching data on live and dead hatchlings, and eggs is collected. Turtle mortality and egg theft is also noted. Tärnlund (1999) reported a tagging program running in collaboration with the South African program. However, no report has been found of turtles been tagged at Inhaca Island. Results Table 6.1.

Contributors: Eduardo J S Videira 1 & Álvaro Costa pipocas99@yahoo.com; 2 ajc_2009@yahoo.com.br Sources: Louro (2005) Introduction It is believed that Macaneta beach is an important nesting area for both loggerhead (Caretta caretta) and leatherback turtles (Dermochelys olivacea). The adjacent waters constitute a development habitat for green turtles (Chelonia mydas; Hughes, 1971; Louro, 2005). However, conservation and monitoring initiatives in this area are practically inexistent. According to Louro et al. (2006), there used to be a conservation program coordinated by a local tourism operator Jay s. However, no information is available. In 2002 the Project for Biodiversity Conservation and Sustainable Development in Macaneta started, with among several objectives, aimed at protect, monitor and tag marine turtles accidentally caught in fishing nets (Louro et al., 2006). Methodology and Sampling Effort In the 2007/08 season, a monitoring program covered approximately 20 km, between Macaneta 1 (north) and Pontene (south), during the period from September to March. Patrols were conducted daily on foot, early in the morning by three community agents, divided in three zones: Macaneta 1 Hodjana; Hodjana Macaneta 2 and Macaneta 2 Pontene. The following parameters were collected: i) species identification; ii) Presence/absence of tags; iii) Number and location of tags; iv) nest/no nest. Whenever possible, marine turtles captured incidentally in beach seines were tagged. When tagged were tagged, the method of capture and morphometric data was also noted (Louro, 2005). Tags were supplied by the Mozambiqe Marine Turtle Tagging Program and had the following codes MO801 MO820 and MO1051 MO1100. Results Table 7.1.

MANHIÇA Compilation: Contributors: Marcos A M Pereira, AICM, Maputo. marcospereira@gmx.net Nico Pretorius & António D Matavele, Maragra Açúcar Angling Club Introduction The Manhiça coastline (Machubo and Calanga beaches), between Macaneta and Bilene, has largely been ignored with regards to research, monitoring and conservation of marine turtles. According to information gathered in Calanga (Narane et al., in prep), at least two species nest in this area, the leatherback (Dermochelys coriacea) and other hard-shelled species, probably the loggerhead (Caretta caretta). Other species identified by fishermen as occurring in the area are the hawksbill (Eretmochelys imbricata) and green turtles (Chelonia mydas). This is typical of southern Mozambique as previously reported (Hughes, 1971; Louro et al., 2006). It was also noted (Narane et al., in prep), that the Maragra Açúcar Angling Club, has been carrying out monitoring and education and awareness activities with the local communities, with regards to the protection of nests and adult marine turtles. The results presented in this chapter resulted from this work during the 2007/08 season. Methodology and Sampling Effort Two community members were recruited to patrol the beach, aproximtely 10 km southwest and 10 km northeast of the Maragra Açúcar Angling Club (S25 o ; E32 o ). These look for nests or tracks. The nests are signalled by poles and after the their location is geo-referenced with a GPS, the nests are dissimulated. None of the nesting females were identified.

41 09. BILENE Compilation: Contributors: Dalila A Narane. AICM, Maputo. dnarane@yahoo.com Eduardo J S Videira 1 & Jeremias A Massango 1 pipocas99@yahoo.com Introduction Similarly to other locations, very few studies were conducted in the Bilene coast. Hatton et al. (1996) superficially mentioned the occurrence of marine turtles in the area and suggested that five species occur: green (Chelonia mydas), hawksbill (Eretmochelys imbricata), olive Ridley (Lepidochelys olivacea), loggerhead (Caretta caretta) and leatherback (Dermochelys coriacea). Additionally, they reported that two of them, the leatherback and hawksbill, nested with latter needing confirmation. This constitutes thus, the first quantitative report on marine turtle nesting in the Bilene area. Methodology and Sampling Effort Marine turtle monitoring in Bilene initited in 2007/08, with a course on the biology, conservation and tagging and monitoring techniques. This course was held in December 2007 in collaboration with the Center for the Sustainable Development of Coastal Zones (MICOA), and 2 representatives of INAMAR - Bilene, 6 community rangers, 5 rangers of the proposed Bilene Special Reserve, one community leader and 1 police officer attended. (Videira, com. pess.). Beach patrols initiated right after the course and were conducted by the reserve rangers, supervised by the Bilene Port Captain. Patrols were conducted daily, on foot from Praia da Rocha to about 5 km southwest, near Mahati village. Marine turtles were identified, nests confirmed and the location of the nests relative to Praia da Rocha (in km) registered. Patrols also monitored and protected the nests in order to prevent disturbances by the local population or wild animals (Videira, com. pess). Results Table 9.1.

CABO DE SÃO SEBASTIÃO Compilation: Dalila A Narane, AICM, Maputo. dnarane@yahoo.com Sources: Kyle & Keiser (2007) Introduction The São Sebastião peninsula and adjacent terrestrial area were declared the Cabo de São Sebastião Total Protection Zone in 2003 (Decree 18/2003 of 29 of April). This zone includes a significant marine component were marine turtles are considered common (Kyle & Keyser, 2007). Marine turtles occur in the deep sea, off the eastern shore, as well as in the shallow, more protected waters of the western shore. The loggerhead (Caretta caretta), green (Chelonia mydas) and leatherback (Dermochelys coriacea) turtles have been seen in the area. It is also possible that the olive Ridley (Lepidochelys olivacea) and hawksbill (Eretmochelys imbricata) turtles occur in the area. This needs to be confirmed (Kyle & Keiser, 2007). There are reports that nesting occurs in the eastern shore of the peninsula, both to the north and south of the São Sebastião lighthouse. Kyle & Keiser (2007) reported based on interviews that nesting occurs in the lighthouse area in the summer months. Two species were mentioned, the leatherback and probably the loggerhead, since the later nests on the mainland, south of Vilankulos and on Bazaruto Archipelago (Kyle & Keiser, 2007). Methodology and Sampling Effort Kyle & Keiser (2007), visited the area in 2005 and 2006, and obtained general information on marine turtle occurrence and nesting through interviews and visits to the potential nesting beaches. Marine turtle monitoring in the São Sebastião peninsula started in the 2007/08 season after a course on the biology, conservation, and monitoring and tagging techniques held in January A representative of the administration, guards and sailors of this conservation area attended the course as well as members of the local community, in a total of 17 participants. The monitoring initiated immediately after the course and conducted by eight people from the local community, which attended the course. Patrols were done daily, on foot, from the São Sebastião lighthouse to Muravane, to the north, and to Nhaxindlane, to the south (within the limits of the conservation area). During the patrols signalled with poles and whenever possible the GPS coordinates were taken. 40

46 This area received tagging material from Ezemvelo KZN Wildlife South Africa (Kyle & Keiser, 2007) and also from the Mozambique Marine Turtle Tagging Program (tags with the following code series were supplied MO851 MO900). However, no information is available on marine turtle tagging in the area.

AICM, Maputo. dnarane@yahoo.com Contributors: PNAB & Eduardo J S Videira pipocas99@yahoo.com Sources: Videira & Louro (2003); Videira (2005) Introduction Five species of marine turtles occur in the Bazaruto Archipelago National Park (BANP; Hughes, 1974). Of these, it has been confirmed that four nest in the area (Pereira & Videira, 2007), namely the loggerhead (Careta caretta), leatherback (Dermohelys coriacea), green (Chelonia mydas) and hawksbill (Eretmochelys imbricata). The conservation of these reptiles was one of the main objectives for the proclamation of the park in 1971 (DNAC, 2002). Work on marine turtles initiated around 1994, when the monitoring started (Pereira & Videira, 2007). Few studies on marine turtles were conducted in the BANP. Therefore, there is a need address aspects of the biology and ecology of these reptiles within the BANP (Pereira & Videira, 2007). The local population in the past heavely exploited marine turtles and their eggs for human consumption. This, however, improved substantially due to the conservation activities carried out by the park authorities since 1989 (DNAC, 2002). Currently it is believed that no turtles are directly targeted, with some of them being accidentally caught in fishing gear. Usually, these are released (Pereira & Videira, 2007). It is also believed that the marine turtle population in the archipelago is much lower that what it used to be when the park was proclaimed due to factors such as an increase in the artisanal and industrial fisheries, both in the archipelago and surrounding areas, added to illegal fishing by foreign long-liners (Videira, 2005). Methodology and Sampling Effort Since 1994, the marine turtle monitoring in the BANP is conducted by the park rangers (Videira & Magane, 2007). Early in the morning, during the nesting and hatching seasons (October to March), park rangers patrol the eastern shores of the islands (mainly Bazaruto, Benguérua and Magaruque). The nests and/or tracks are marked, dissimulated and controlled daily. Whenever possible the identification is done from the track and later confirmed after hatching (Videira & Magane, 2007). Upon hatching the following data are collected: i) species identification; ii) number of hatched eggs; iii) number of un-hatched eggs; iv) number of eggs laid; and v) total number of dead hatchlings. The majority of the data presented here (relative to the 1994/95 to 2002/03 seasons) were compiled and analysed by Videira & Louro (2003), from monitoring forms available at the BANP. 44

ILHAS PRIMEIRAS E SEGUNDAS Compilation: Contributors: Eduardo J S Videira, AICM, Maputo. pipocas99@yahoo.com Alice C D Costa 1 & Associação dos Pescadores Artesanais de Angoche 1 adabulacosta@wwf.org.mz Sources: João (2006) Introduction Few studies and monitoring programs were conducted on Primeiras and Segundas islands. The distribution of marine turtles throughout the country (Hughes, 1971; Louro et al., 2006; Costa et al., 2007) suggests that the following species occur in the area near the islands: loggerhead (Caretta caretta), green (Chelonia mydas), hawksbill (Eretmochelys imbricata) and olive Ridley (Lepidochelys olivacea). However, local fishermen only identified the last three (Sitoe, 2006). Hughes (1971), suggested that the Primeiras islands was the largest nesting area for green turtles in Mozambique, especially Fogo island, Casuarina and Epidendron. Beside green turtles, two other species might nests in the area, the hawksbill and olive Ridley (Costa et al., 2007). According to local fishermen, these three species nest on Segundas islands (Caldeira, Mafamede, Puga-Puga and Njovo; Sitoe, 2006). The nesting period in the area has not been adequately identified. João (2006) reported that it runs from June to November, nevertheless the majority of local fishermen interviewed said that the nesting period goes from August to December (with a peak in November). Some of them also declared that marine turtle nesting lasts all year long (Sitoe, 2006). Therefore, the nesting period should run throughout the year, with some peaks similarly to what happens further north in Vamizi island (Hill & Garnier, 2004). Monitoring and tagging activities in the area initiated in 2005 (João, 2006), althugh marine turtle protection and conservation started in 2002/03 and have been carried out ever since. Activities are especially implemented in Segundas islands (Mafamede, Puga-Puga, Njovo and Caldeira) by community guards of the Associação dos Pescadores Artesanais de Angoche (APAA) with financial support from WWF Moçambique. Methodology and Sampling Effort At the beginning of the protection, monitoring and tagging program in 2005, 28 community guards were trained by Mr. José João, in identification, monitoring and tagging techniques. A continuous follow-up was done from July 2005 to June 2006 on Puga-Puga, Mafamede and Njovo islands. Nests were counted, species identified and nesting females or other turtles caught on fishing nests were tagged (João, 2006). In December 2007, another course on the biology, identification, monitoring and tagging of marine turtles was taught to the guards. In this occasion, tagging information was gathered. No data on nesting was available as the guards keep these in their personal 52

58 logbooks. Only tagging data is registered in forms and sent to WWF s central office in Maputo.

AICM, Maputo. pipocas99@yahoo.com Alice C D Costa 1 & Parque Nacional das Quirimbas 1 adabulacosta@wwf.org.mz Costa (2007a) Introduction Costa (2007a) identified three species of marine turtle in the Quirimbas National Park (QNP): the green (Chelonia mydas), hawksbill (Eretmochelys imbricata) and olive Ridley (Lepidochelys olivacea), the green turtle being the most common. The loggerhead (Caretta caretta) could also occur, given its distribution throughout the country (Hughes, 1971; Louro et al., 2006; Costa et al., 2007). Nests of the green, hawksbill and olive Ridley have been confirmed in the park and the season runs from October to May (Costa, 2007a). Costa (2007a) also reported that turtles mating are a common sight in the park, especially close to Ibo Island around August to September. Thirteen beaches have been identified within the QNP, as suitable for marine turtle nesting; this includes both islands and the mainland (Costa, 2007b). Marine turtle monitoring and tagging activities initiated in 2006, after some rangers underwent training (João, 2006), although protection and conservation activities started in 2002 after the park s proclamation. These activities have been conducted ever since. Methodology and Sampling Effort Park rangers stationed at selected places with marine turtle occurrence (especially islands) record nesting and tagging data. These are then sent to the park office in Pemba. The main islands were there is ongoing monitoring are Quirimba, Matemo, Sencar, Ibo e Quilalea. Quirimba island has three nesting beaches: Paquissico Tchawane (1100 m), Lemani (500 m) and Miocho Matato (400 m). Matemo also has three fine beaches for nesting, namely Muanacomo (2 km), Palussansa and Praia de Matemo. On Ibo Island there are two suitable beaches Ponta Mujaca (1400 m) and Paloco (900 m), although no nest has been recorded so far. In Sencar, a small island, there are three beaches with good nesting properties: Quissico Tchawane (50 m), Nalala (50 m) and the beach on the western side of the island (10 m). Quilalea has a very small nesting beach (Costa, 2007a). Costa (2007a) presented monitoring and tagging data obtained from July 2006 to May Subsequent data presented here, were supplied by WWF-Moçambique. 55
