Greece Schools Booklet 2015 SCHOOL: NAME: Updated: 2nd March 2015 1. Introduction This expedition gives students the opportunity to join a series of research projects in the eastern Aegean. The first week is based on the island of Samos close to Turkey, whilst the second week is spent travelling by a research boat stopping at some of the more remote islands in the Aegean before returning to Samos for the flight home. The research projects are being coordinated by the Archipelagos Institute – a Greek NGO with several research bases around the eastern Aegean, with input from the Operation Wallacea university academic teams. The Archipelagos Institute has a research and conservation management presence year round albeit at a lower level of input than during the Opwall survey season, which then allows year round sets to be collected to determine annual cycles but more importantly conservation interventions to be implemented effectively. During the two weeks the teams will complete the following: dive training to PADI Open Water level a course on Aegean Island ecology participate in a Samos island wide call back and camera trap surveys for the golden jackal on Samos to estimate population size participate in a Samos island wide survey of chameleons to estimate population size and habitat usage participate in bird surveys of a saline lagoon area on Samos learn how to conduct standardized sea grass surveys using snorkel and kayak methods and complete surveys at a series of sites participate in cetacean and oceanography surveys assist with surveys of bird and invertebrate communities on a series of remote islands designated as Wildlife Refuges assist with fishery landing surveys on Lipsi island assist with baseline data collection on a cove which will be turned into an open sea aquarium where the original Aegean marine ecology before the impacts of Man will be recreated assist with geological erosion monitoring of several small Dodecanese Islands Section 2 of this report describes the facilities at each site and an example schedule for the two weeks. Sections 3 – 15 describe the different training courses and research projects. Updated: 2nd March 2015 2. Facilities and example schedule In Samos the groups will stay at the Archipelagos Institute research centre just off the village of Pythagorio. Accommodation is in shared rooms with up to 4 people with hot showers and flushing toilets. The research station has lab and lecture facilities. Moreover, Archipelagos has a minibus in order to carry the students among the different sites. For the second week: a) Large student groups (>14 students) will travel on the Golden Arrow, a 35m oak boat that can host in the cabins up to 25 students. Archipelagos has facilities on the different islands, so if the student group is bigger than 25, there will be extra accommodation facilities in Archipelagos’ research stations. b) Smaller student groups will travel via the Archipelagos sailing boat. The boats are fully equipped with navigation, safety and research equipment. The student groups will travel with the boat first to the Lipsi island complex where they will spend the first 3 days. Archipelagos has a great relationship with the local fishermen and the local community as a whole on this island, joining forces and working together for the protection of the unique sea of the area. From here they will sail to Arki Island, a scenic island with only 45 inhabitants. It is at the centre of a complex of 14 small islands that have been designated as wildlife refuges because of their bird communities, including breeding populations of Eleanora’s Falcon and Audouin’s Gull. Protected from mass anthropogenic disturbance, it is a perfect spot to study wild fauna and flora of the Aegean Sea. The group will stay on Arki Island for two days including a visit to the neighbouring small island of Marathi. Finally, Archipelagos bases across all sites and boats have kitchen facilities to provide authentic Greek meals. The groups are divided into several smaller teams to complete the surveys and table 1 describes the typical timetable for two groups: Day Location 1 morning Samos Welcome lectures what are you doing and why and settle into base 1 afternoon Samos Aegean Island Ecology and Research Objectives lecture 1 1 evening Samos PADI theory lectures 1 and 2 2 morning Samos PADI confined water skills 1 – 3 Protected Marine species - lecture 2 2 afternoon Samos Protected Marine species - lecture 2 PADI confined water skills 1 – 3 2 evening Samos Jackal and chameleon survey PADI theory lectures 3 – 5 3 morning Samos PADI confined water skills 4 – 5 Bird survey of proposed salt marsh 3 afternoon Samos PADI theory lectures 3 – 5 PADI confined water skills 4 – 5 Updated: 2nd March 2015 Activity group 1 Activity group 2 3 evening Samos Protected Terrestrial species lecture 3 Jackal and chameleon survey 4 morning Samos Bird survey of the salt marsh Open Water dive 1 4 afternoon Samos Open Water dive 1 Bird survey of the salt marsh 4 evening Samos Jackal and chameleon survey Protected Terrestrial species lecture 3 5 morning Samos Open Water dive 2 Seagrass survey protocol training 5 afternoon Samos Seagrass survey protocol training Open Water dive 2 5 evening Samos Terrestrial survey techniques - lecture 4 Jackal and chameleon survey 6 morning Samos Fish identification and UVC Open Water dive 3 6 afternoon Samos Open Water dive 3 Fish identification and UVC 6 evening Samos Jackal and chameleon survey Terrestrial survey techniques - lecture 4 7 morning Samos Open Water dive 4 Pythagorio Cultural Visit 7 afternoon Samos Pythagorio Cultural Visit Open Water dive 4 7 evening Samos Marine survey techniques - lecture 5 Marine survey techniques - lecture 5 Sail to Lipsi Island.

PADI Open Water dive training course This course consists of theory lectures and tests which are completed with instruction from a fully trained Dive Instructor at the research centre. This is accompanied by a series of skills that need to be learned and these are completed in shallow water in front of the main base. Once the theory and skills training has been completed the students will then complete 4 Open water dives to a maximum depth of 18m. They will then be signed off as qualified Open Water divers and can register with PADI (Professional Association of Dive Instructors). Students will need to bring their PADI Open Water manuals with a PIC (Personal Identification Card) that is then used to register with PADI once the training course has been completed. These can be purchased from the Operation Wallacea website prior to expedition (http://opwall.com/get-involved/buy-padi-pack/) For those students who are already dive qualified or for those who want only to snorkel, these dive training sessions will instead be used to help with the sea grass surveys either by diving for qualified divers or from snorkel surveys for those who don’t want to dive. Visibility in the Mediterranean is normally up to 40m so the diving is an amazing experience. 4. Aegean Island Ecology course The Aegean Island Ecology course covers the following topics which are designed to train students in the ecology, conservation issues and survey techniques that are being used on the surveys. In addition, many of the topics (e.g. quadrat and transect surveys, invasive species etc.) are included in their biology or environmental management syllabuses for A level, Scottish Highers, AP or IB syllabuses (see Appendices 1 – 3 for syllabus matching information). The lectures, films and practical exercises on this course will help the students become immersed in the ecology and conservation issues of the Mediterranean and will cover the following areas: Updated: 2nd March 2015 Aegean island ecology and research objectives; Formation of Aegean islands, how we know which islands were connected from DNA studies of island fauna, island specialists such as Eleanora's Falcon, Audouin’s Gull, importance of the islands as migration routes for birds and whales, unique populations of golden jackal and chameleons on Samos Island, conservation measures to allow flamingos to breed and open sea aquarium concept. Protected marine habitats and species in the Mediterranean; Coralligene reefs in 40 – 60m depth and sea grass habitats. Protected marine species marine mammals, turtles, sharks and rays. Threats to protected marine habitats and species including illegal fishing, shipping accidents, aquaculture etc. Important island species and their conservation; Special birds, amphibians, reptiles and mammals of the eastern Aegean. Land management conservation issues such as fire, erosion, pet trade collection, and road kill etc. Survey methods for island species; Quadrat surveys for flora, invertebrate sampling techniques such as light trapping, sweep netting and fogging.

Invasive species in the Mediterranean; Examples of invasive species. How they arrive and impacts on local flora and fauna. Attempts at control or eradication Conservation in the Mediterranean; Examples of where conservation has been successful in the Mediterranean. Policy issues and how species and habitats are protected. First Aid for marine mammals and turtles; Practical skills in how to help injured marine mammals such as Monk seals or dolphins and treatment of injured turtles Problem of plastics pollution in the sea; Issue of plastic waste in the oceans. Breakdown rates and micro plastic impacts on the food chain. Updated: 2nd March 2015 5. Golden Jackal surveys Samos is the only island in the Mediterranean which has a population of the Golden Jackal. There is thought to be a population in the low hundreds on the island and this research project is designed to produce reliable data on the population size to compare with the population levels estimated in 2005. The jackal population has had a beneficial impact on the island allowing reforestation to occur much more widely compared to other islands because the unrestricted grazing of goats is not economical given the predation risk from jackals. The island has been divided into a series of habitat types and over the course of the Opwall season survey teams will visit a series of randomly selected sites in each habitat type shortly after dark and will use recorded jackal calls to elicit responses from any other jackals in the area. In addition camera traps and baited sand trays will be set up at the site and left to run overnight. The survey teams the following day will pick up the camera traps and baited sand traps for additional evidence of jackals. 6. Chameleon surveys Samos has a population of chameleons which until recently was under considerable hunting pressure for sale in the pet trade. The Archipelagos Institute has been helping to reduce the hunting pressure through assistance with enforcement activities and an educational awareness programme. Estimates of the remaining population size and recruitment rates as well as habitat selection are now needed. The same habitat divisions as defined in the jackal project will be used, with spotlight surveys of transects being completed to determine the distribution of chameleons. All chameleons sighted will be captured, their gender and age determined and, if adult, marked with a combination of coloured marks before being released. The GPS position of each animal captured will be recorded as well as a series of habitat variables. These habitat variables are being used to produce species distribution models for the species. 7. Bird surveys of saline lagoon On the southern part of Samos Island is a saline lagoon which exists for much of the year and which attracts greater flamingos. In addition, this site is used for breeding by ruddy shelduck and blackwinged stilts. The flamingos have not bred to date however, probably because the lagoon tends to dry out by the summer. The Archipelagos Institute is proposing that the saline lagoon is retained year round by pumping sea water during the summer months when it is normally dry. This maintenance of water levels coupled with installing raised platforms which could be used by breeding flamingos may encourage this species to breed on the island. This is how flamingo breeding was encouraged in the Camargue in southern France. All other lagoon areas have been drained on the island and there is pressure to also drain this area. The attraction of breeding flamingos and other bird species should encourage tourist visits and potentially provide sufficient reason to maintain the lagoon. Students working on this project will be joining an expert ornithologist and helping with transect surveys of the lagoon and surrounding areas. All birds seen or heard will be identified and any evidence of breeding activity noted. Updated: 2nd March 2015 8. Standardised Seagrass Watch surveys The eastern Aegean has some of the most extensive seagrass beds in the Mediterranean and because of the exceptional water clarity these seagrass beds extend in some areas down to a depth of 40m. These seagrass beds are important nursery areas for many juvenile fish and crucial for security of the fishery. A series of permanent 50m x 50m quadrats have been positioned on representative seagrass beds around various islands in the eastern Aegean and these are being monitored annually using the standard Seagrass Watch survey protocol developed by the Australian Institute of Marine Sciences (http://www.seagrasswatch.org/home.html). Snorkelling students on this survey will be helping with photographing quadrats to assess seagrass cover and free diving to measure the height of the seagrass blades as well as to determine the main species in each quadrat. Snorkelling surveys of these seagrass quadrats can only be completed up to a depth of 5m. Students who are already dive trained by the time they arrive on the project will, after completing a check dive, be diving with a Dive Master to complete surveys of the deeper lying quadrats. 9. Kayak – Seagrass mapping In addition to the seagrass surveys, Archipelagos has developed a monitoring technique of the Posidonia seagrass meadows using kayaks. Per group of 10, students will kayak above the seagrass meadow to be surveyed. The kayaks will share a depth gauge (whose readings can be seen in real time via tablets on the other kayaks) as well as a camera and bethoscopes. The combined use of this equipment will allow the students to monitor and map the area of the seagrass meadow, as well as human impacts these may suffer from. Kayaks are considered an ideal, eco-friendly means to research coastal habitats, while the great clarity of the Aegean waters (which can reach 40m) make it possible to survey up to large depths. They cause no environmental impact and do not produce any noise. Therefore during the seagrass mapping, bird observations can be done and with some luck marine mammals observations as well. 10. Marine mammal surveys The waters around the eastern Aegean are noted regions for sperm whale migrations. In addition, the area is used by smaller cetacean species such as the 4 dolphin species regularly recorded. Data on cetaceans are gathered from transects whilst the Archipelagos Institute research vessels are travelling between sites. At regular points along the transect hydrophones are used to listen for whale calls. In addition, the GPS position of all cetacean sightings are noted. At the sites where the cetaceans are sighted various oceanographic data are taken (e.g. depth, temperature and salinity profile). Updated: 2nd March 2015 11. Bird and Invertebrate Surveys of islands designated as Wildlife Refuges In 2013 the Archipelagos Institute managed, with strong support from the local communities, to persuade the Greek government to designate 14 islands around Arki as Wildlife Refuges. Arki Island has 45 inhabitants and the remaining islands designated in this way are mainly unpopulated. Some of the islands are used as breeding sites for Eleanora’s Falcon. They nest in August such that the chicks hatch to coincide with the late summer migration of passerines returning to Africa – a preferred prey item for the adult falcons. These rare birds can be seen performing aerial acrobatics around the cliffs of some of these uninhabited islands. In addition, some of the islands may be used by other rare breeding species such as shearwaters and Audouin’s Gull. Students working on this project will be travelling by small boats and landing on these remote islands with an ornithologist to complete bird surveys. In addition, since very little is known about the invertebrate fauna of these islands, collections of invertebrate fauna are being made using light traps which will be left running overnight and picked up the following morning as well as from sweep net surveys. The samples collected will be sorted into Orders and labelled before export to specialists in the various taxa for identification. 12. Fishery surveys Students working on this project will travel by boat to Lipsi Island where extensive data sets have been collected over the last couple of years on fish landings and how these relate to fish stocks as recorded from trap nets and video surveys. The first task is to help measuring the catch from returning boats and complete a fishery monitoring form for each boat that identifies the type of gear used and fishing effort. Lastly, underwater remote video monitoring devices will be deployed at various depths and left in the water for a fixed period before retrieval. Analysis of the video will help to determine the maximum numbers of each species seen over the time period. 13. Open Sea Aquarium monitoring Tourism in South Africa depends to a large extent on the success of the Game Reserve concept where large areas of bush have been completely fenced and the ecosystem restored to the conditions that would have occurred before Man’s impacts. Visitors can then roam in vehicles or with armed guards on foot in large areas of bush that contain good populations of lion, cheetah, elephant, rhino, buffalo and the accompanying bird and reptile fauna. This has done much to maintain the biological diversity of South Africa and some of the reserves are huge – the Kruger Park alone for example is the size of Wales! The Archipelagos Institute is aiming to create a marine version of this Game Reserve concept by netting off an elongated and deep bay on the island of Lipsi. During the first phase in 2015 a first section of the bay will be enclosed with the net (approximately 400m long X 100m wide), while during the second phase in 2016, the whole bay will become enclosed. The nets will be made of the strong material used in fish cages and a double wall of nets will allow them to be lifted separately for Updated: 2nd March 2015 cleaning, whilst leaving the whole area still closed off. The concept is to allow the ecosystem in this enclosed bay to return to its natural state prior to the huge impacts of fishing pressures that have decimated much of the Mediterranean. Water clarity is so good that tourists in glass bottomed boats or using scuba gear should be able to witness a restored Mediterranean ecosystem. This open sea aquarium concept for Lipsi Island appears to be the first time that the idea has been attempted but if successful could provide a beneficial model for both protecting marine species and also for increasing tourism revenue. Students working on this project will be helping with sea grass monitoring surveys as well as Underwater Visual Census (UVC) surveys in the proposed bays where this concept will be developed to provide baseline data. This year will be the first year of monitoring, so as the bay is enclosed, this standardised monitoring will continue over following years to track the changes in the ecosystem, and compare at the same period to a control area to prove the benefits of the aquarium. 14. Standard geological surveys Land erosion is a big issue for the Mediterranean islands, for the impacts it has on their rare fauna and flora, but also for the economic activities based on these islands. Erosion is caused by a combination of natural factors as well as anthropogenic impacts. The lost land threatens the sustainability of the islands. Making use of monitoring protocols developed in collaboration with the Geological department of Athens University, students will collect data for long term monitoring for the land reduction on different island sites. This project will help to better understand the causes of the erosion and lead to possible management recommendations. Appendix EPQ and Extended Essays Many students are now involved in producing Independent Research Projects (IRP) as part of their 2 year educational programme and many hope to carry this out whilst on an Opwall Expedition. If you are an IB school you will be involved in the EE or Extended Essay or if in the UK an EPQ or Extended Project Qualification. Those involved in CoPE will also have a similar task in which they carry out some research. There are many similar projects in most countries. One of the key features of all of these ‘Essays’ or ‘Projects’ is that you have to choose your own research question but it is often difficult to find out exactly what is happening at each Opwall research site. To help in this, we have produced a ‘Research’ lookup database on the Opwall website – http://opwall.com/epq-research-topic/ but you can also ‘download’ a more detailed version as an Excel Spreadsheet. The database lets you find out what is happening at each site and there are links to PDF files and video clips. You can search the ‘database’ using a variety of filters such as research area and location. This booklet also contains detailed information on the research projects you will be involved in and this may help you to locate your particular area of interest. Updated: 2nd March 2015 The type of IRP will vary but it is less suitable for individual investigations where you collect your own primary data although in some cases you might be able to get hold of raw data and you will often have the opportunity to help collect some of this data yourself. You will certainly have the opportunity ‘on-site’ to meet up with the scientists involved which will allow you to get a deeper insight into your research question. Many of you will also have seen the Wallace Resource Library (WRL) which contains many datasets based around the research being carried out and it has been prepared by the actual Opwall scientists involved. It is a very valuable source of ideas with comprehensive datasets to look at and study. Demo version – http://wallaceresourcelibrary.com Do also make use of the research library on the OpWall website How does it work? Once you have an idea send an email to [email protected] with your initial ideas and contact details so that one of the academic staff working with Opwall can contact you to discuss possible research questions. We can also send you further information to help you choose a suitable title for your research site. Once you have decided on a title you will then be asked to complete a registration form (supplied on request) which we can then forward to the appropriate country manager or scientist. This will then inform those at the research site about what you are hoping to achieve plus for us to give you as much assistance as we can. In some cases we will also be able to provide you with data sets from previous years which some students will find very useful. Deadlines: Although each school will be operating their own schedule we would like registrations to be competed at least 3 months before their expedition begins although the earlier the better.
