What is SINNG?

The Student Invasive Non-Native Group or SINNG is a Local Action Group based at Cornwall College, Newquay. Launched in 2010, our goal is to increase awareness and reduce the impacts caused by Invasive Non-Native Species (INNS) on native wildlife. We do this through practical fieldwork such as pond clearings, Himalayan Balsam removal and much more. We also continue to research the effects, spread and impact of INNS on native species.

SINNG is mostly comprised of student volunteers from all seven Cornwall College campuses. We also have an international link with SINNG Helicon in The Netherlands.

My experiences at SINNG

I originally started helping out with SINNG to gain experience of working with children, as I want to become a primary school teacher. Therefore most of my work has involved the educational side of SINNG,  including volunteering at the ‘Saplings’ after school club, helping run workshops in schools throughout Cornwall and creating education materials.

At the ‘Saplings’ after school club we try to incorporate a broad range of INNS ideas. This has included looking at the effect pets can have on native wildlife if they escape or are released into the wild and become invasive. These after school clubs have also provided good opportunities to test out new materials we have made, including our Alien Invaders game and a game I created called ‘Guess Who’s Invasive’, which went down really well with the children, especially if they had played ‘Guess Who’ before.

During the school workshops that I have helped run, a wide variety of games and activities have been used to engage the children. Using microscopes and ID guides to identify invasive pond plants and native invertebrate always goes down well.

With the school workshops, the session is adjusted to fit what the children have been learning. For example, in a workshop at St Columb Minor, Newquay, they had already been learning about food webs, so we talked about the effect INNS can have on food webs and ecosystems as a whole. Using the invasive Australian Flatworm as an example, we showed how they eat native earthworms and the knock on effects that can follow. One important aspect of a workshop is showing pupils what to do if they find an INNS. On our website we have a ‘Submit a Sighting’ page which allows the public to record any INNS in their area.

How did it all go?

One of the great things about SINNG, is that I feel at the end of a session the children have leant something they didn’t know before. I think this is because the sessions are run in a fun and interactive way. Plus at the end of most sessions the children are tested, using our interactive activities, on what they have learnt.

Activities which require participation from the children, such as the bicarb and vinegar experiment, always go down well.

The most important part about the educational side of SINNG is that children can enjoy themselves whilst learning about important environmental issues.

Denise Spaan is the Field Station Coordinator and Conservation Education Manager for The Little Fireface Project which was set up to help protect the slow loris in Indonesia. We caught up with Denise to ask her more about this fascinating species and the important work being done to conserve it.

How did you get into science / conservation and what do you love most about the work you do? What are the challenges you face?

From a young age I have lived in many countries, including primate range countries such as Ivory Coast and Rwanda. It is there that I developed an interest in animals but was also faced with the reality of poverty. I saw conservation issues up close. At school I was very interested in biology and went on to study zoology as my undergraduate degree. When presented with the option of doing a placement year I jumped at the opportunity to study chimpanzees at a rescue centre in the Netherlands. Whilst there, I was introduced to the welfare issues associated with primate pets and gained an interest in wildlife trade. My final year module of Conservation Biology affirmed what I had seen when I was younger and made me want to become a conservationist. I went on to do a Masters degree at Oxford Brookes University in Primate Conservation. It is there that I developed the skills needed to become a conservationist and primate researcher. It was also there that I was introduced to the plight of the slow loris.

What I love about the work I do is the versatility that it offers. I am involved in all aspects of the work that the Little Fireface Project does in Java. Seeing the children’s faces light up when we tell them what we have planned for them that day is extremely rewarding. What I love most is seeing them learn and seeing how, every week, they remember more about the slow loris. My nights in the forest with the lorises fill me with admiration and wonder. Learning about a species is one thing, but then seeing them in the wild is very special.

Challenges come in many forms. Some are small, such as the drinking water tank needing to be refilled (we manage to spill water every time), and others are larger challenges. Recently we found a civet trap on one of the paths used by the lorises. Lorises are very vulnerable to such traps and will get caught in them, and of course we are here to instil love for all the wild animals, meaning the civets too. At moments like that it is important to act fast, deactivate the trap, and think up an appropriate education programme. Within one week we had a volunteer draw some civet colouring pages and we went to talk to the farmers.

Why do you think Arkive is important?

Arkive is a wonderful reference tool for professionals, students, and everyday people with an interest in the world.  The information is presented in such a way that is more accessible to a broader audience. Scientists often struggle to present their data to the public so that it can be easily understood.  Arkive is a wonderful reference that presents solid scientific facts, beautiful photos, videos, and references.  This is a wonderful way to unite scientists and animal-lovers across the globe.

What can people do to help slow lorises?

Slow lorises are often made victims of their own cuteness. Because of their big eyes and soft fur, many people think that they would make a good pet. Many tourists are not aware of the critical state in which lorises exist. Therefore, one of the most important things anyone can do is not to buy a loris in an animal market. By buying a loris you endorse the trade and as most are wild-caught, you thereby endorse taking animals from the wild. Additionally, many lorises are used in the photo prop trade. Please don’t have your photo taken with a loris when on holiday in places like Thailand, or buy it thinking you can simply hand it over to a rescue centre – there is always a new one ready to take its place on the streets.

Be a responsible consumer. Products that contain palm oil are some of the biggest contributors to loss of habitat, and therefore loss of species in Southeast Asia.  Many people know that this industry has a negative effect on orangutans, but numerous other species, including slow lorises, macaques, langurs, civets and leopards, suffer from this loss of habitat as well. Try and buy products with sustainable palm oil or without palm oil.

People can also support organisations like the Little Fireface Project that work to save lorises.  By visiting www.nocturama.org you can see exactly what our project is doing to protect these species.  We have an adoption programme for some of our study animals as well as a shop with project t-shirts and other items. Of course, donations are always appreciated.  These contributions make a vital difference to what we are able to do in the field to protect these species.

Everyone remembers their first encounter with a whale shark, just as we all remember that first kiss, but experience has taught me that each encounter is in some manner just as unique as the first time.

When I first began diving the northern islands of Wolf and Darwin in the late 1980´s, we really had no idea of the species that we were going to find. Already Darwin´s Arch had begun to get the reputation as being the best dive site in Galapagos. Within days of my arrival to these distant shores I heard rumours of schooling hammerheads, Galapagos sharks and the strangely named ¨Pez Gato¨ or ¨catfish¨ as the fishermen referred to whale sharks. I later learned that the white spots on a whale shark where likened to those of the jaguar. Perhaps some of the fishermen had spent some of their formative years in the Ecuadorian Amazon jungle!

As time progressed we became aware that the whale sharks were aggregating on a seasonal basis, much more frequent during the cold garua season between June and November. The larger animals were thought to be males, although as with many shark species the female whale sharks are larger on average than males. It was only when we began actively checking for male claspers that it became apparent that most of the sightings were actually of females.

By the beginning of the new millennia I was already convinced that most of those whale sharks that passed by Darwin were not only adult females, but that they were also pregnant! Their distended abdomens appear to confirm this, but how could we get solid scientific evidence? It’s not so easy when they average over 10 m in length and weigh upwards of 20 tons. Researchers working with other large pelagic sharks such as tigers and great whites are able to capture the animal and carry out certain medical procedures in a controlled environment, much as we do with humans. The shark is winched onto the deck and immobilised and although there are strict time limitations, blood samples may be taken and an ultrasound test carried out.

This is simply not possible given the size and nature of the whale shark, so how do we propose to do this? Certainly a challenge as this has never been tried before. Blood samples have been taken from captive whale sharks, but never ¨on the fly¨. Picture a diver with no means of propulsion but his fins and leg muscles, chasing down an animal the size of a single decker bus with a 4 knot current in a thousand feet of water! Sound exciting?

Next season we hope to have members from the Georgia Aquarium join us in the field to attempt taking a blood sample from a whale shark in the wild, for the very first time. They already have extensive data of the blood chemistry of captive juvenile female whale sharks that are not pregnant. By comparing the blood chemistry of a female in the wild that we are 90% certain is pregnant, we may be able to determine how close to birthing she is. We also hope to try the worlds first underwater ultrasound using a waterproof prototype unit that is self contained and can record video and still images. Perhaps this will give us an indication of the stage of development of the embryos, as well as numbers of pups. Each encounter with a whale shark provides us with more information.

Developing new techniques in order to answer some of the many questions that still remain about their natural history has always held great appeal, for it is that voyage of discovery and the resulting data that may help protect whale sharks in the future, wherever in the world they roam.

1aOur oceans are critical to our very existence; it’s a simple matter of healthy oceans = healthy people.  Besides providing us with food (today almost one in six people in the world rely on fish as their primary source of protein), oceans provide us with many other important services that our survival depends on.  They maintain our renewable supply of fresh water through the water cycle, regulate our climate, and produce more oxygen than the world’s rainforests. With growing concern over climate change, we are turning more and more towards the oceans for clean, renewable energy.

In addition to being an important source of protein, many marine organisms have been found to provide therapeutic uses in antioxidant, antiviral, anti-inflammatory, anti-fungal, or antibiotic medicines. Additionally, the marine and coastal ecosystems offer endless recreational opportunities such as sea kayaking, sport fishing, surfing, whale watching and scuba diving, activities which not only feed our souls, but also drive economic benefits through employment for local peoples.

2a

Today almost one in six people in the world rely on fish as their primary source of protein.

Although critical to our existence, our oceans are in desperate trouble.  Depleted fishery stocks, habitat destruction, pollution, coastal development, climate change and invasive species, are some of the major issues threatening the healthy existence of our oceans.  In the Pacific Ocean for example, there is an area 1000 kilometres from the US coast which is larger than the entire land mass of South Africa and which is covered in plastic. It contains six times more plastic than plankton, and is growing all the time as more than 10 million tonnes of plastic finds its way into the sea each year.

The marine and coastal ecosystems offer endless recreational opportunities such as sea kayaking, sport fishing, surfing, whale watching and scuba diving.

This current state of affairs is largely as a result of the dilemma known as “The Tragedy of the Commons”, in which multiple individuals acting independently in their own self-interest can ultimately destroy a shared limited resource, even when it is clear that it is not in anyone’s long term interest for this to happen.

Our oceans are in desperate trouble. Depleted fishery stocks, habitat destruction, pollution, coastal development, climate change and invasive species, are some of the major issues threatening the healthy existence of our oceans.

Overfishing, together with global climate change and habitat destruction, are considered as the three major risks facing our oceans. When looking at this, obviously the first thing that we have to do is to control our own levels of exploitation. That means fishing within the biological limits of a fish population and assuring that the gear that we use does not destroy habitats. Today, many stocks are just hanging on to survival because of regulations that were inadequately or not properly enforced in the past. We need to abide to these regulations and support good science that guides the future regulatory parameters around fishery off-take.

5a

Fishing is taking place across food chains and thereby breaking down the efficiency of the oceans.

Globally, as human populations continue to grow, along with the popularity of seafood, fish stocks are coming under increasing pressure and can no longer keep up with pressure of current commercial fishing operations. A recently published report on the state of the world’s fisheries by the United Nations Food and Agricultural Organisation (FAO), estimated that approximately 80% of the world’s fisheries were fished at (52%) or beyond (28%) their maximum sustainable limits.

Overfishing, together with global climate change and habitat destruction, are considered as the three major risks facing our oceans.

Increased levels of fishing do not only result in the overexploitation of our marine resources, but also results in the destruction of marine habitats. More than 50% of the world’s total marine catch (81 million tons) is harvested using towed fishing gear. Studies have shown that fishing can damage the seabed by, for example, breaking deep-water coral reefs and other fragile habitats.

The United Nations Food and Agricultural Organisation (FAO), estimated that approximately 80% of the world’s fisheries were fished at (52%) or beyond (28%) their maximum sustainable limits.

Habitat destruction is not only about the physical loss that may come from the destruction of a reef or the damming of a river, but also from pollution, diverted stream flows, and even the introduction of invasive species. Through habitat destruction, biodiversity is negatively impacted which ultimately is the cornerstone of a productive ecosystem that in turn drives the fishery resource upon which we depend. We know that 85 % of all commercially valuable fish are dependent upon wetlands and estuaries during some part of their lifecycle. Two-thirds of our estuaries and bays are already severely degraded through torrents of chemical and other poisonous runoffs and irresponsible development and agricultural practises.

8

Pollution is negatively impacting on the biodiversity of our oceans.

Protecting our oceans and coast is more than stopping pollution and regulating fishing. It also means controlling our activities onshore and controlling unregulated coastal development. With all of these poisonous pollutants running into the oceans, “dead zones” have been created where only some of the smallest marine organisms can survive. These areas are created in significant part by synthetic nitrogen fertilizers flowing into the sea and nourishing massive algal blooms which then decay and cause oxygen- depletion, killing everything except the hardiest in its vicinity.

We know that 85 % of all commercially valuable fish are dependent upon wetlands and estuaries during some part of their lifecycle.

Although these kinds of reports on the state of our marine resources may be disheartening, it is important for us to realize that there are solutions, and that if we all work together, we can turn things around. Marine Protected Areas are globally recognised as an essential tool for marine conservation and for helping restore the health of our oceans. They allow for the protection of habitats and provide areas where fish species can grow and breed without disturbance. As habitats are able to re-establish back to their natural state, they help in preventing damage from severe storms, reducing the impacts of pollutants while also aiding in reducing the impacts of climate change.

Protecting our oceans and coast is also about controlling unregulated coastal development.

Where fishing is concerned, it is important that all stakeholders abide by set fishing regulations and laws- we need to build a culture of voluntary compliance and self-regulation. Fisheries need to start implementing what is known as an Ecosystem Approach to fisheries (EAF), which seeks to protect and enhance the health of our marine ecosystems as a whole, to ensure the long-term survival of marine life and the communities that depend on it.

Marine Protected Areas are globally recognised as an essential tool for marine conservation and for helping restore the health of our oceans.

It is also important that we promote a sustainable seafood trade. By simply asking questions about our seafood and making more informed choices about the fish that we trade, buy and eat, we could make a huge impact in influencing positive change in the seafood chain of custody.  But this requires urgent and concerted effort from all parties involved- from the fishing industry all the way to the consumer.

12

It is important that all stakeholders abide by set fishing regulations and laws.

Our oceans are a common heritage, and we all have the responsibility and the ability to help conserve and protect them- if not for our sake, then for the sake of future generations- our children.

Support the South African Seafood Initiative (SASSI) and only eat and buy the healthiest and most well managed fish populations.

More tips on what you can do to help save the oceans:

1. Support South Africa’s Marine Protected Areas
2. Eat sustainable seafood: Support the South African Seafood Initiative (SASSI) and only eat and buy the healthiest and most well managed fish populations. For further information visit: www.wwf.org.za/sassi
3. Don’t dispose of trash or toilet waste in the ocean.
4. When enjoying recreational fishing, obey regulations and try to enjoy only catch-and-release fishing and use care when releasing fish back into the ocean. Take photos, not fish
5. Keep beaches clean. Plastics and other debris harm sea life and pollute the ocean. Clean up after yourself. Get involved! Participate in beach cleanups if you live in a coastal area.
6. Don’t purchase items that exploit marine resources unnecessarily such as shell and coral jewellery and sharks teeth.
7. Spread the word: Tell people what’s going on with the world’s oceans and what they can do to make a difference.

As the first light of day spills over the sea like lava, we set off in a small boat to explore the waters around Goat Islands. Paulette, the only registered fisherwoman in the community, tells me when I ask about local opinion about the development, “The government claims it will bring jobs and opportunity to the area, but we are not qualified, and we are not being trained, for the jobs that will need to be done. They tell us what they want us to hear, but the reality is that we will be worse off”. I recently read a comment that said the government is, “selling straw baskets to the poor to carry water”, and could not think of a better analogy.

As we circle Goat Islands, Herman points out two fish sanctuaries fringing the mangroves and asks, “How can they say this won’t impact our livelihoods?” Despite being protected under four laws and containing two forest reserves, six game sanctuaries, and three fish sanctuaries, and despite the fact that the Jamaican Constitution states that all Jamaicans have “the right to enjoy a healthy and productive environment free from the threat of injury or damage from environmental abuse and degradation of the ecological heritage,” the government appears to believe it can sell off a living, breathing ecosystem for the right price. The reasons that other sites, such as Kingston Harbour, have not been considered have not been fully explained.

The old adage says that we will conserve only that which we love. I cannot claim to love Goat Islands, and my relationship with Portland Bight Protected Area has been fleeting. After experiencing it first hand, I do feel more of a personal affinity to the place and to the people fighting to protect it, and can claim to appreciate its unique beauty.

As a photographer, my job is to translate my personal experiences of being there into something universal; to move others to feel as I did. But as I try to decipher what made me care enough to hop on a plane to Kingston, I keep returning to the feeling that was stirred in me before I had set foot on Jamaican soil; before I had sat in dappled limestone forest overlooking the Hellshire Hills, or stared into a star-filled sky over the Caribbean while sand cooled my feet. I keep returning to how I felt when I first learned of the loss of somewhere I had never been. What I felt was outrage that something as sacrosanct as a protected area – a natural treasure – could be sold off for a quick profit. I felt empathy toward those that had devoted their lives to recovering the Jamaican iguana, and angry that all their hard work could go up in smoke. I felt as if I had just learned that the government of Italy was chipping away at the ceiling of the Sistine chapel to sell piece by piece. This was not the world that I wanted my son to know; and so, I had to play my part to try to protect Goat Islands.
