Working With The Funzi Turtle Club (Day 1)
Category: Community Conservation, Environmental Education, Funzi turtle club, Mangroves, Turtles | Date: Nov 10 2009 | By: gvikenya
This past Wednesday found the GVI marine team travelling from Wasini Island to Funzi Island for two days of training with the Funzi Bay Turtle Club, a local community effort to save endangered sea turtles. Currently there are about 30 members in the club, 20 of which, including the chair, are females from this traditional Muslim community on the island.
Since we usually spend our days on the water monitoring local and migratory marine species, to have two full days on dry land was quite a change of routine.
Douglas explaining the importance of sea turtle conservation
Upon arrival, we were met by one of the club members and taken to our house, where we met up with KESCOM volunteers Sonya and Avidad from Sweden, here for three months. KESCOM (Kenya Sea Turtle Conservation Committee) currently supports many grass-root turtle conservation efforts along the Kenyan coastline. This support comes in the form of monetary donations, grant writing, providing volunteers, management and contacts with other local organizations. Douglas is the KESCOM Funzi Island representative.

After our introductions we proceeded to the village for a tour and to the mangrove forest for a planting session. Since mangroves are among the fastest disappearing ecosystems in the world, each tree really counts! The turtle club also runs a shop with some very unique gifts made by local community members, and we all spend some time and money there.
Following a fabulous meal cooked by the ladies of the turtle club (one of many such delicious meals) we began our training with the group. Our goal was to help the club members learn to interact with tourists and to give them information that tourists would like to hear, in addition to giving them important information about habitat conservation. We showed a number of PowerPoint presentations to the group and with the help of Douglas on the Swahili translation, gave them information about ocean conservation, sea turtle identification and morphology, and local whale and dolphin species. Club members were extremely interested in learning and asked a number of thought provoking questions following each presentation.
Mangroves
One of the most common questions asked by the community members was how to explain to the other islanders (100% of which are fishermen) topics regarding conservation of the ocean environment. We were able to provide some examples, but in the end had to explain that changing people’s minds is a very slow process. Since entanglement in discarded fishing nets is one of the biggest threats to marine animals, we suggested that this was a good issue to start with in the community. We were very impressed with the concern of the club members about the welfare of the ocean habitats and animals, especially in an area of the country where ecosystem destruction and human disturbance is prevalent.
Overall, both sides seemed very pleased with the progress made during the first day of training. The volunteers of GVI would like to thank KESCOM and the Funzi Bay Turtle Club for there generous hospitality and delicious traditional food.

The Art Of Breathing

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.

Bottlenose Abundance In Kenyan Coastal Waters
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.

Humpback Whale Season Begins in Kenya
Category: Cetacean research, Humpback whales | Date: Jul 05 2009 | By: gvikenya
Hello there! After a rough week of stormy seas and torrential (and somewhat mysterious!) ‘black rain’ brought by the Kusi monsoon winds, Friday left us with something to celebrate… well, a pair of somethings actually.
Monday was a training day for us, teaching our new researchers how to identify different turtle species, dolphin species and their larger cousins the humpback whales. Tuesday was… a total wash out! Torrential rain kept our research boat and research team firmly moored at Mkwiro. Wednesday and Thursday saw us out on the choppy water but the winds kept us confined to the Wasini channel. A brief sighting of a green turtle and bottlenose dolphin were all we got for our efforts and in rough seas following the dolphin sighting and undertaking photo identification surveys proved too difficult.
Friday was looking to be a similar story as the planned survey route to Funzi bay was abandoned and we turned back in to the Wasini channel, however it turned out that we didn’t need to venture as far as Funzi bay… we barely needed to venture off our base in Mkwiro village as it happened. On re-entering the eastern end of Wasini channel the research team were confronted by two seasonal visitors in front of Mkwiro… a pair of humpback whales! We’re not sure that this particular pair was a mother and calf, although one was smaller, it certainly wasn’t a new born and as this marks the beginning of Kenya’s 2009 humpback whale season, we’re expecting mothers to be on their migration north up the East African coastline before they calve.
However it is very exciting for us to see the humpback whales (the fourth largest animal in the world as I learned recently!) return and for those of us here last year, the significance of last Friday, 3rd July, wasn’t lost on us. Last year, the first sighting of humpback whales in the area relayed to us, was on 3rd July! We can’t wait to find out what else we can learn from them over the coming months and if we’re lucky we may have a chance of finding out if any of the individuals we photographed last year have returned for 2009.
Stay tuned, we’ll be blogging our way through the 2009 humpback whale season for you!

Humpback Dolphins Sighted With Four Calves
Category: Cetacean research, Dolphins, Humpback Dolphins, Kisite Mpunguti MPA, Turtles | Date: Jun 04 2009 | By: gvikenya
Today we chugged our way along the coast of the Shimoni peninsula all hoping for an exciting day to finish off the marine research week. Not long after leaving the Western end of the Wasini Channel our hopes were fulfilled when Shafii sighted Indo-Pacific humpback dolphins just off the coast. First contact was with a mother and calf but shortly afterwards we spied another group about a hundred metres away and so headed off to check them out… and were rewarded with a group of twelve to fourteen humpback dolphins literally frolicking in the shallow waters.
Humpback dolphins are meant to be ’shy’ but this group were anything but as they spy-hopped, breached, swam around the boat and generally showed off, posing for the paparazzi on the boat. Most excitingly, there were four mother and calf pairings - baby humpbacks are particularly cute with their little humps and tiny dorsal fins and they gave our two photo-identification photographers plenty of opportunities while the rest of us ooh-ed and aah-ed at the display. It can’t be a bad day when you are sat on a boat in the sunshine watching a group of dolphins at a time of day when you would normally have been arriving at the office to start work! We had a spectacular snorkel in the warm waters off Kisite Island then spied a turtle swimming on the surface as we headed back to base.

Bottlenose Dolphin ‘Besty’ And Her Calf At Kisite
Category: Cetacean research, Dolphins, Kisite Mpunguti MPA, Turtles, bottlenose dolphins | Date: May 26 2009 | By: gvikenya
As I mentioned before, the Kusi winds and rain make life difficult for dolphin research on the open seas. Yesterday our efforts on the water went unrewarded again… although I stick with my little mantra that “no data is still valuable data”!
Today however the team aboard ‘Lampard’ started with a promising early sighting, a group of four bottlenose dolphins sighted around the eastern end of Wasini Island. But the rough seas made for tough conditions under which to follow the small travelling group, let alone try to take the photos from which we would be able to try and identify the individuals.
So the search continued, rounding the end of Wasini Island in to Mpunguti marine reserve, cruising between the two Mpunguti islands and on in to Kisite marine park. The destination was Kisite Island where we hoping that the sheltered side would allow us at least to look for turtles in the water along one of our snorkel transects. However before we ready to jump overboard, another group of four bottlenose dolphins approached the boat as the wind and waves subsided… leaving us with good conditions and a perfect opportunity to get back to what we had been trying earlier, photo-identification.
Besty with her distinctive dorsal fin notches
Both Andy and Jamie were armed with cameras in a photo-ID duel. It was the two adult dolphins that were our key target, as they would hopefully be individuals catalogued over the past 3 and a half years that we could recognise. And in fact they both were, Nene (or individual 083) and Besty (individual 017 - the 17th individual we formally identified, from 2006). Besty was accompanied by her calf and the fourth individual was a sub-adult. With the local dolphins having been elusive for much of the last few months, it was pleasing to enjoy these four showing off in the calm waters around Kisite Island. The calf in particular seemed to be in playful mood, posing for the camera with ’spyhops’ - holding the head vertically out of the water.

No turtles on the transect, but the day was far from disappointing and seeing Besty again is like meeting up with an old friend.
