The activity of dolphin (whale)-watching is described as “the commercial observation of cetaceans in their habitat from a platform on land, sea or air” (Hoyt 2001).
The dolphin-watching industry constitutes an emergent business in many coastal areas around the world and has seen spectacular growth over the last fifteen years. The industry began in the 1950’s in San Diego (California) and has since expanded as far as Antarctica. During the 1960’s, the industry grew significantly in the United States and Canada, followed by Australia, New Zealand, the Canary Islands, Japan and Norway in the 1980’s (Hoyt 1995, 1996) and, Iceland, Philippines, Indonesia, Hong Kong and Tonga in the middle of 1990’s.

 
In 1998, the number of dolphin-watching tourists totalled around 9 million, estimating the volume of income generated to be 1 billion US Dollars, doubling the income in 1994 (Hoyt, 2001). In 1998, of those nine million participating in dolphin-watching trips, one million were from the United States alone. More recently, other countries and regions such as the Canary Islands and Canada have reached similar volumes. Australia and South Africa are expected to double their numbers from 500,000. (Hoyt, 2001)
This activity has been developed in more than 492 communities with the majority experiencing a real transformation. Dolphin-watching provides important incomes, creates new activities which generate new employment and moreover, constitutes a very useful tool to study marine mammals and marine environments.
Whale and dolphin watching have become an increasingly popular and financially important tourist activity along the East African coast.  Currently, dolphin research and conservation efforts are being undertaken in Tanzania (Zanzibar) and Mozambique within the Sustainable Dolphin Tourism in East Africa Project. However, to date, few studies of cetaceans have been undertaken in Kenya and there is an urgent need to initiate research to aid future conservation and management of the species found in Kenyan coastal waters.

A bottlenose dolphin being watched by tourists in the KMMPA 
Global Vision International (GVI) Kenya has set up a new project focused on the dolphin-watching activity of Kisite-Mpunguti Marine Protected Area (KMMPA). The objectives of this project are to collect information about the socio-economic impact of tourism operation on the area and to analyze the sustainability of increased levels of human-dolphin interaction.  Further, to identify existing problems and to propose constructive changes to respective government institutions that would help boat operators, tour companies, and the local residents in running the activity sustainably. These objectives will in turn add value to the Code of Conduct for KMMPA, developed by Kenya Wildlife Service in 2007.
Aims:
 1. Analysis of the socio-economic activity (dolphin-watching) in KMMPA.
 2. Impact of tourist dhow boats on the cetacean population.
 3. Education and awareness of boat operators and tour guides.

The data will be collected through interviews to tourist, boat operators, hoteliers and local community members in Mkwiro, Shimoni and Wasini. Also, GVI research vessel will assess the impact of this tourism investigating the abundance, distribution and behaviour of Indo-Pacific bottlenose dolphins (Tursiops aduncus). Moreover, we will compare sightings and behaviour on different areas and with different levels of tourism activity that will allow us to evaluate the Code of Conduct. And finally, GVI will create awareness and education of local dolphin species and habitats engaging the boat operators and tour guides in different projects so as to promote conservation issues.

Devon Tighe is a two-week volunteer, assisting with GVI’s marine conservation research. She hails from New York City where she does strategic research at the New York Times.

Back home in New York City I practice yoga. Now, let’s be honest: When most people think of yoga they think of a flaky, tree-hugging, hippy-types sitting around crossed-legged, chanting long, sonorous “om”s. Allow me to attest that this is not the case. For many of us, yoga is, very simply, about breathing.

Regardless of whether you come from New York, London, Nairobi or Mkwiro Village, I imagine you have heard the expression “just breathe”. In the literal sense, breathing is the natural, instinctual mechanism that keeps oxygen flowing throughout our bodies and keeps us alive. In the more prosaic sense, we associate breathing with the calming of our nerves, the steadying of our focus. Or, as we often say in the yoga studio, with the “letting go”.

When I participated in my first dolphin survey, we were fortunate to come upon an extraordinarily large pod of forty dolphins. While the mere sight of them was stunning, what I found myself most mesmerized by was the sound the animals were making.  When dolphins surface for a peduncle dive – which is the arc-shaped swimming movement most of us are familiar with – the animals exhale out of a blowhole that lies several centimetres in front of the dorsal fin. While we were out among the large pod, I was surrounded by the gracious, full-bodied sound of exhaling as the dolphins heaved gusts of air out of their graceful, dancing bodies.

“They are letting go” I kept thinking to myself. As we do in yoga, they are linking movement with the breathe. They are steadying themselves to stay on course. With that wonderful sound of spewing breathe, they are pushing out the dynamic force that connects us all – humans, dolphins, all the precious life in our world.

When I return to the hustle and bustle of New York City when I am finished with my time here on Wasini Island, I have no doubt that one of my favourite memories will be the sound of the dolphins. Exhaling.

Category: Butterflies, Shimoni Forest | Date: Oct 23 2009 | By: gvikenya

When I first came out here to GVI Kenya in July 2008, I never thought I would become an avid fan of butterflies.  To be honest, I would have laughed at the thought (as would many of my friends back home in England!), but I now proud to say otherwise.

As part of our biodiversity research in Shimoni east forest, we monitor butterfly diversity and abundance.  We are trying to put together a comprehensive species list, as well as record any changes in species presence, distribution, or changes in abundance.  We do this for several reasons. 

Charaxes brutus.  Here you can see its proboscis very well (the curly red thing) which is used for feeding.

Firstly, butterflies are a very well studied taxon.  They are also easily identifiable (they are 90% identifiable by external characteristics), and we can do it ourselves relatively accurately using a book (Larsen 2006).  They are also excellent ecological indicators due to their very specific plant and habitat associations.  So by monitoring them, we can indirectly monitor the health of the forest. 

 Charaxes brutus

And finally, they have a trait that plays straight into our hands.  They can only take off upwards.  This means they are very easy to trap!  We use things called canopy traps, which comprise of a board with a pot of bait in the middle.  A couple of inches above the board is a cylindrical tube of mosquito netting.  So the butterflies fly onto the board to feed on the bait, then when they attempt to fly away, they fly straight into the net!

The face of Charaxes brutus

Once caught, we remove them from the net, and take photographs of the upperside and the underside for later identification.  Getting them out of the trap is fairly easy.  You grab them by the sides of the thorax, which is the middle section that houses all of the muscles for the legs and wings.  You can then use your other hand to slide your finger between the wings and get a grip of the thorax from the top and bottom.  The butterflies we catch in the traps tend to be the larger species, and they are very strong!  It still surprises me how solid their thorax is, and the strength of their wings.  By using this method, we can be sure not to touch their wings or harm the butterfly.  Once photographed, we let them fly on their way.  An example of the grip we get is shown below.

Papilio demodocus demodocus

I decided to write this blog because Andy (a new edition to GVI) has a camera with an amazing macro setting, allowing us to get some really cool photos of the butterflies.  Enjoy the close ups!

Well my arms are aching and my hands are blistered, yet I feel the need to let everyone know about why…

We have been doing primate and biodiversity research on Shimoni east forest for almost 4 years now, and are getting some robust data.  Yet just across the road on the other side of Shimoni village lies the uncharted, and mysterious realm of Shimoni west, ever beckoning us to it.  We have been planning to expand our research into Shimoni west for a while now, and have finally begun the adventure. 

The girls ready for the day

The western forest is almost twice the size of its counterpart, and teaming with flora and fauna that are crying out for recognition.  There is definitely a viable population of our beloved colobus monkey, as highlighted by the censuses conducted in 2001 by Julie Anderson and in 2007 by GVI.  That is the only time GVI have officially done research in West, and Anderson’s census is the only other event. 

We have on occasion, ventured into Shimoni west on fact finding missions and with the intention of making preliminary assessments into the possibility of starting research in there, and one thing we have noticed is the high level of disturbance ranging from charcoal pits, pit saws and snares.  This only increased our sense of urgency.

 Katie getting stuck in

So as of last week, we have officially begun our preparations.  By preparations, we mean donning work gloves, sharpening our pangas (machetes) and practicing our angry faces and heading into West to begin the long and tiresome process of cutting transects.  Transects are an essential part of research (specifically for distance sampling – the method of survey we use for the primates), which involves cutting paths in a grid system that allow us to pass relatively easily through the research area.  We do try and minimize the damage we cause, so there is always plenty of crawling and climbing! 

Matt’s panga face

We’ve started cutting our north / south spine, which will run approximately 1 – 1.2 km through the centre of the forest, off which our research transects (that run east-west) can cross.  We have done two days so far, and have gone approximately 600 metres!  That may not sound like much, but trust me on this – it’s not bad!  This endeavor will take many months to complete (as we still have to carry on our surveys in East), but we’ll keep you updated on our progress. 

Once more into the breach dear friends!

Category: Kisite Mpunguti MPA, Turtles, mpunguti island | Date: Oct 21 2009 | By: gvikenya

Around 2000 years ago, trade in sea turtle products was observed in the Red Sea and East Africa region and although trade in ambergris and ivory occurred, tortoise and turtle shell was the most commonly mentioned product.  (Jack Frazier, Proceedings of the Western Indian Ocean Marine Turtle Conservation Workshop, Mombasa, 2005). All five species of Indian Ocean sea turtles are considered to be endangered and can be found in Kenya. Green turtles (Chelonia mydas) are reported to nest throughout the coastline but although there are some green turtle nests confirmed in the nearby area of Funzi Island, sea turtles haven’t laid their eggs in the KMMPA (Kisite-Mpunguti Marine Protected Area) for at least seven years.

So it was with great joy that last week GVI Kenya heard the good news about a green turtle visiting the white sandy beach located in the Lower Mpunguti Island. Lily, from Coral Spirit Restaurant, located in Wasini village, shared with us the pictures she took while she was visiting the island.

This is an amazing happening in this Marine Protected Area, and will hopefully contribute to the conservation efforts GVI and its major local partner KWS (Kenya Wildlife Service) are putting in place in the area. The islands of Mpunguti are known to support an important population of coconut crabs, nesting sites to African fish eagles, and its surrounding waters are frequently visited by Bottlenose and Humpback dolphins, as well as Hawksbill and Green turtles that feed on sea grass and algae. Both local fishermen and KWS rangers still recall the days when the turtles came to lay eggs on the Lower Mpunguti Island, the only sandy beach available for setting up the nest.  It has been almost seven or eight years since the last turtle arrived on the Lower Mpunguti Island.

Green turtles typically live about 45 to 59 years. Given that a female nests in six or seven of those years and lays about 330 eggs each nesting season, she will produce 1900-2300 eggs in her lifetime. Factoring in natural predation, fungus infection of nests, and other embryo failure rates, one can expect each healthy female to produce 1000-1900 hatchlings (Spotila, James R. Sea Turtles, 2004). This information emphasises the importance of a single nest in this region. Although this turtle did not lay its eggs, she might go back to the nesting place or other turtles might look for this place as an option to nest. The next crucial step in this process is to take management actions in order to protect the nesting area and recognize it as a non-disturbance place.

The historic decline of green turtles is one of the most cited and best documented conservation issues. Its population has declined 50-70% since the 1900’s and they are recognized internationally as endangered by the World Conservation Union (IUCN) and are protected in the Appendix I of the Conventional on International Trade in Endangered Species (CITES) and in Appendix I and II of the Convention Migratory Species (CMS).

The Kenya Sea Turtle Conservation Committee (KESCOM) was established to complement government commitment to addressing global concerns for marine turtle population decline. GVI works closely with KESCOM in sea turtle conservation efforts, through research, education and capacity building activities such as training in biology and ecology of sea turtles. The data and the pictures collected in our study area (KMMPA) are shared with this organization in order to recognize and protect important foraging, mating and nesting areas for sea turtles. The ultimate goal is to restore green turtles to population levels at which they can fulfil the ecological roles they performed in the past.

Category: Kenya Wildlife Service, Shimoni Forest, yellow baboon | Date: Oct 20 2009 | By: gvikenya

Yesterday saw an interesting discovery for us GVI folk here in Shimoni forest.  We were at the end of the negative sections of transect 5, innocently conducting a butterfly sweep net survey, when we were stuck with a very intense smell of decay.  We spent a good few minutes trying to establish the source, but soon discovered where it was coming from.  Tucked away right at the foot of an impressively sized baobab tree, lay the semi-decayed corpse of a yellow baboon!

Baboons are a very widespread and successful group, who can be found in most places across sub-Saharan Africa.  They are certainly abundant in Kenya, and there is a lively population here in Shimoni.  In many places in Africa, they are a bothersome crop pest, and are even listed as vermin in some countries.  Here in Shimoni however, the yellow baboon (Papio cynocephalus) are found in the actual forest itself, and are still wild and shy, avoiding humans at all costs and surviving on the fruits of the forest alone.  This makes them a fantastic animal to see when in the forest, and a relatively rare one. 

This photo shows the whole body in the foetal position, with the left arm out behind its back

So you can imagine our surprise when we stumbled across this poor fellow!  Its very difficult to say exactly what happened to it, especially as none of us here are experts in dead bodies or establishing causes of death!  There were no obvious injuries or wounds that gave it away (we did look quite closely), although there was a lot of dry blood around the body.  It was at the foot of a big baobab, so perhaps it fell out of the tree?  It was also right on the edge of a shamba (farm), so the idea of it being killed by a vengeful farmer is not impossible either.

This shot is from the other side, again of most of the body

What did strike us as strange was the apparent lack of scavenging of the body.  Almost all the skin was in tact, with none of it appearing to have been eaten.  Perhaps it was the location of the body – in the shadow of a big tree – that has allowed it to remain invisible and untouched by the many scavengers in the area.

 A closer look at the head

It was a very interesting find; never before have we been allowed such a detailed look at the anatomy of a baboon, yet I fear the mystery of its death will remain unsolved.  We will be informing the Kenya Wildlife Service of our find.  I am however, going to ask their permission to bury it, and then to keep the skeleton (once it has fully decomposed), as it would be really interesting to have a full baboon skeleton to use as an educational tool.  I’m not sure what protocols they have regarding dead animals, so this may not be allowed, but there’s no harm in asking!

If we come to any conclusions about the cause of death, we’ll let you all know!

If you cast your eyes back over a few of our blogs recently you’ll read about the tourist trail that Friends of Shimoni Forest are creating.  This trail is going to run through Shimoni forest to show tourists some of the amazing flora and fauna to be seen, it will take them on a visit to a couple of the sacred Kaya’s or traditional religious sites, and it will take them past some of the amazing mangrove forests that run along the whole eastern coastline. 

An example of some of the mangroves

Mangroves are some of the most amazing trees in the world.  They tend to inhabit coastlines, estuaries or river mouths, and form some of the most critical habitats on the planet.  They act as nurseries and hunting grounds for countless aquatic species, as well as a home to many terrestrial species such as baboons and genets.  They also act as a buffer zone between fresh water bodies and the sea for runoff, silts and pollution.  They are also the only tree species that can exist in salt water!

Mangroves happily exist on beaches

Because of their importance, coupled with the fact they are exceptionally cool, means they are a site not to be missed on the tourist trail.  There is one particular spot where the tourists are going to be taken where at least five different species of mangrove can be seen, and where they extend unbroken for kilometers. 

The original idea was to create a boardwalk through the mangroves, which the tourists would be taken along.  This idea was scrapped, mainly because there are several mangrove boardwalks already in the area, and we wanted ours to be extra special.  So we have come up with the idea of a viewing platform!  We want to build a very tall (and very safe of course…) structure of some sort, on which the tourists can sit, drink a cup of chai and look out over the huge expanse of mangroves to the east, and the towering trees of shimoni forest to the south and west.  We think this will deliver a unique experience to people who have come to see this stunning area. 

One of the magnificent trees of Shimoni forest

Of course there are going to be many issues involved in the creation of this structure.  We are not sure yet what materials will be used in the construction, but bamboo has been suggested already.  The structure will need to be built on coral rag (fossilised coral), which will not be the simplest base for a tall structure…!  Then of course there is the issue of finances, which as ever, will probably be the hardest to overcome.  But overcome it shall be!  It will be the best view in Kenya (excluding Mount Kenya perhaps…)!

Have you ever asked yourself what you would do with your day if you were a colobus monkey?  Perhaps not, but down here in Shimoni east forest, we are rather curious…

GVI has been conducting primate behaviour surveys on the colobus monkeys for about two and a half years now.  It has been a constant effort, but unfortunately we have never dedicated as much time and energy into it as we would have liked.  This is due to the fact that our forest research programme has many parts to it, with an array of different surveys that all require our attention. 

We have been privileged recently though, by the presence of a masters student from Manchester Metropolitan University who has come out to do his thesis on colobus behaviour in Shimoni forest!

Gareth has been with us for over ten weeks now, and still has approximately five weeks to go.  He has been stomping through the forest during every waking hour in search of our beloved colobus, with the hope of quietly observing and recording their behaviours. 

The main outputs one wants from behavioural surveys are time budgets.  These are simple breakdowns of what the colobus actually spend their time doing (normally as a percentage of total time).  So for example you could observe that during the early hours of the morning, an adult male may spend 60% of his time feeding, whereas during mid day, this may be replaced by resting (say for perhaps 85% of the time).  Whilst one is recording states (which are longer durations e.g. feeding and resting), one is also recording events, which are of a shorter duration, or “instant” events such as urination, or scratching.

You may be asking yourself why we would be interested in these details of a monkeys life.  Well, apart from being amazing to watch (they are scarily human-like!), these observations can tell us much about the wellbeing of the population, the impact of environmental pressures, the effects of human presence / absence, and the impact that human disturbance is having on different populations. 

For example if you were to observe a troop that reside deep in the forest well away from human presence, and then compare those results to a troop that is near recent destruction, you may observe some serious differences.  The troop deep in the forest may spend more time feeding in the morning and evening, and resting during the middle of the day – what they should be doing.  The troop closer to human disturbance may spend more time alert, or travelling.  This reduces the time they can spend on activities such as feeding, or socially important behaviours like grooming.  You do not need to be a genius to guess that this will be likely to have implications for the health of the individuals and the troop as a whole.

 Observing colobus in their natural habitat

So we are very happy to have Gareth here with us, and are extremely excited to see his results.  They may well reveal some distressing facts, which I have no doubt we will be able to link to the increasing destruction of the forest.  But the first step is collecting this data, and analysing the results.  Once we have firm conclusions, the next question will be “why?” and the next step – how do we stop it.

East African coastal forests are some of the most critical habitats for wildlife conservation in the world. Once upon a time they were a continuous belt that stretched from Somalia down to Mozambique, and were home to some of Africa’s most diverse and unique wildlife. Unfortunately today, what remains are small, isolated and fragmented patches, in which the wildlife is becoming more and more vulnerable.

 One of the many new roads scarring the forest

GVI has been conducting disturbance surveys in Shimoni forest for over three years now, and have a solid and robust set of data, which highlight the plight of this beautiful area. The main aim for our research in the forest, is to be able to hand it over to Friends of Shimoni Forest (a community-based organisation), which will empower them to lobby, apply or petition for things like land allocation or protective status for the forest.

The work of illegal loggers

We have been very encouraged recently however, as government organisations and the local administration have actively approached us for our data and results, as they too are very concerned with the level of destruction. Off the back of this, we have spent a lot of time putting together a disturbance report, which summarises our results over the years. This report has been written on behalf of Friends of Shimoni Forest, and has been submitted to Kenya Wildlife Service, Kenya Forest Service, the Chairman of the County Council, the District Commissioner, the East African Wildlife Society and the IUCN.

A charcoal pit in action

It is massively encouraging to know that our results are being looked at by so many people, and that the number and range of people concerned with this destruction is ever increasing. We cannot wait to work with everyone in the future, so that together we can put a stop to it.

Category: Cetacean research, Dolphins, Kenya Wildlife Service, Kisite Mpunguti MPA, bottlenose dolphins | Date: Oct 14 2009 | By: gvikenya

Kisite-Mpunguti Marine Protected Area (KMMPA) lies south of Wasini Island (south-coast of Kenya) and covers an area of 39 square kilometres. The KMMPA includes the National Park surrounding Kisite Island and the Marine Reserve surrounding the Mpunguti islands. The KMMPA and the marine wildlife it contains are an important tourist attraction and, as a result, an important resource for Shimoni and surrounding communities. The islands within the KMMPA are surrounded by coral reefs attracting divers and snorkelers to the area. Almost every day dolphin-watching companies operating from Shimoni travel through Wasini Channel to the KMMPA. These tourist dhows most frequently encounter Indo-Pacific bottlenose dolphins (Tursiops aduncus), and less frequently, Indo-Pacific humpback dolphins (Sousa chinensis).

Global Vision International (GVI) Kenya’s main working partner is the Kenya Wildlife Service (KWS). The research conducted by GVI is shaped to satisfy the objectives of KWS, so as to assist them towards better management of the area.  All data collected thus far is made available to KWS to aid in management plans of the study area. The Marine Programme is supporting KWS to collate data by conducting vessel surveys, which was focus on assessing the bottlenose dolphin abundance on the area, during the initial phase.

After three years of cetacean research in Kisite-Mpunguti MPA, GVI has estimated the absolute abundance of bottlenose dolphins around 122 individuals, being the second biggest population of Indo-Pacific bottlenose dolphins (Tursiops aduncus) in East Africa. The largest population of the species inhabits in Kizimkazi (south-coast of Zanzibar), and holds between 139 and 179 individuals (estimation made by University of Stockholm in 1999-2002).  

Photo-id and mark-recapture methods were the methodology used on both studies to get the estimation. Photo-ID refers to the identification of individuals by distinctive features (shape, outline, natural markings and scarring) of their dorsal fins, flanks and flukes. Some scars will be retained through life, whereas others will be added and may fade through life. The depth and severity of the wound will determine the length of time this may be used for identification. These features allow known individuals to be re-sighted. The re-sighting rate can be plotted on a discovery curve, the plateau of which suggests population size. Photo-ID can also be used to determine residency and demographic data such as inter-birth intervals, patterns of ranging and mortality.

Mark-recapture methods are used to calculate population size from the proportion of known individuals re-sighted over the study period. Mark-recapture models estimate only the size of marked individuals in the population. Therefore, the total population size has been corrected by the correction factor.

Kenya Wildlife Service applied a code of conduct in 2007 for the tour operators to follow when manoeuvring around the cetacean species; unfortunately it is not being fully adhered to as it has only recently been implemented. The levels of interaction between cetaceans and the tour operators are not being monitored or regulated in any way. The impact these activities may be having is unknown. In particular, it’s not known whether current levels of dolphin tourism are sustainable for the area. The first estimation of Indo-Pacific bottlenose dolphins in KMMPA will allow GVI and KWS to measure the levels of tourism impacts, analysing the population dynamics of this species.
