The sea turtle nesting and hatchling season has come to an end. We haven't had a nest since early August. Our 44th and final clutch of the year hatched about one week ago. The monsoon season, and its accompanying waves (which are a blast to surf in a sit-on-top kayak), is creeping in. So no more Green or Hawksbill turtles will lay eggs and obviously no new young-ins will hatch. As Mr. Womack sang, "it's all over now." Take a glance below at our numbers for 2012. Not atrocious, but not too robust either.
Only 8 female turtles visited 3 beaches. Not to confuse anyone but that's very low. There used to be 2-3 different turtles visiting Mentawak beach (where JTP resides) per night decades ago. This year just 3 showed up - out of 8 months when they coulda nested. The optimistic takeaway is that projects doing hatchery work, protecting eggs and releasing babies have seen an increase in nesting turtles, but we got a long way to go before that's possible for us. Green turtles take 25-40 years before they return to nest (longer than any turtle, marine or terrestrial, in the world). Hawksbills start plopping out eggs a little earlier, after 20 years. JTP has only been around for 6 years, with a government run hatchery operating for 5 years before that. We got some time before it's possible for more turtles to start showing up. Another bright spot: I'm proud of our 88.4% hatching success rate. At least we got as many of those tiny turtles into the ocean as we could.
Alli and I have returned to the U.S. after our 20 months abroad. For a total of 12 of these months we worked on Tioman Island doing sea turtle work (Juara Turtle Project) and outdoor education (Little Planet). The rest of the time we traveled extensively in the Malaysian-Indonesian archipelago, in addition to visiting the Philippines, Singapore, Nepal and Costa Rica.

Urgent: Please Sign Petition for Turtle Friendly Development in Juara
Development is currently underway on Mentawak Beach that threatens the population of Green sea turtles nesting here. Mentawak beach is where JTP resides and where Alli and I have been living since we left the U.S. in April. Most of JTP's work over the last six years, plus ours since we got here, will be in vain if we don't protect this habitat. Action is needed now to make sure turtle-friendly development is put in place or the turtles of Tioman will edge closer to extinction. Please follow the link below and sign the petition. Then spread the word people. Thank you so much everyone!
Petition link: http://www.gopetition.com/petitions/support-sea-turtle-friendly-development-on-mentawak-bea.html
I will be writing more about this pressing subject, as well as what the future holds for sea turtles, JTP and Juara in general, soon on the blog. Stay tuned. Below is a map of the current development plans for Mentawak, as well as photos of the vegetation being cut and habitat for nesting turtles disappearing. *** All photos can be enlarged by clicking on them.***

Notice the red streaks - a lot more chalets, lights and people are being planned for Mentawak Beach. The turtles are going to be pushed out, as well as natural vegetation line along the beach. |
Above two photos: vegetation being cleared directly south of JTP, between us and Lagoon. Notice the photo on the bottom that vegetation still exists right of the sign, but to the left it is gone. |
Above two photos: vegetation being cleared directly north of JTP for a future resort. It used to be very hard to see the ocean from where these photos were taken. Not anymore. |
New chalets going in on the north end of Mentawak Beach. Opening soon. |

These two photos of nesting Green turtles on Mentawak beach could a thing of the past if measures aren't taken for turtle-friendly development to be put in place. |

Saved by Sound
I've been doing the field biology thing for a little while now.
Over the last couple of years I scoured the desert ground for a lot of herps,
sometimes for official business, but mostly for thrills and pleasure - the pure
fun of it. One thing I came to know quickly: listening matters, a lot. Sure,
you need a solid set of eyes to find what you're looking for, but keeping your
ears open and paying attention to the audio cues around you is also mightily
important and useful. Good thing I’ve only seen two Dinosaur Jr. shows in my
life, cause a collection of their ticket stubs has to affect one’s hearing.
I did a stealth walk of the beach with no light
and (of course) up higher, but this discovered nothing. We then decided to
continue our regular walking schedule in hope she would return.
Listening enabled me to see Desert tortoises duke it out and a
Tiger rattlesnake woof down a mouse. I found a lot of Gila monsters and
tortoises this way, plus zoned in on quite a few snakes. And since they shout
out for all to hear, following the calls of toads and frogs usually rewards you
with a slap-happy monsoon pool of amphibian copulation that is always comical
to see. The point is: keep your ears open and sometimes it's alright to just shut
the hell up in the field. And soak up the sounds.
On June 6th turtle watch was on. Louise (named after my Grandma
and pictured above) was expected to grace us with a clutch of eggs for
the sixth time. Since Green turtles can nest up to seven times, but often fall
short of this number we weren't completely positive our first Mentawak Beach
mother of 2012 would return. At 20:23 hours Alli and I saw that she did, except
we messed it all up.
When patrolling a nesting beach the ideal spot to
walk is between the high tide line and vegetation, which is up on the beach
away from the water line. The Lady and I were not following this rule at all.
We were strolling at the water's edge for some reason. I honestly don't know
why. Alli shined her red light ahead of us and there was our large female
breaking the surf and coming onto land. The light went right into her eyes.
After a few quiet, but startled "Holy shits," we retreated away in
hope she would still come on shore. She didn't. We scared her off. She was
coming ashore between JTP and Lagoon, a resort at the end of Mentawak. Now she
was back in Juara
Bay and (hopefully)
plotting to get onto the sand sometime later tonight. Usually when
you interrupt a turtle like this it's the equivalent of being walked in on
in a bathroom stall. You feel semi-violated for a moment and stop what you're
doing, but eventually the process continues. Past experiences say the turtle
would make another landing, especially since it was still early.
She fell in the pit definitely to the tune of Parks and Rec. |
At 23:05 I was strolling the beach and heard some intriguing noise,
which sounded a lot like sand whacking leaves (I need to work on more mysterious
foreshadowing). Not much on the beach this hour makes noise besides turtles
flinging sand, tourists being soused, or your occasional cat mucking about. I
heard it again and again, the sand ramming against the vegetation. I was
walking near the high-tide line and saw no turtle tracks in the area though.
None. The moon was assisting, and along with my red light, I couldn’t find any tracks
at all. I kept hearing the noise and after a minute or so decided to
investigate regardless of the lack of tracks. I got down low and crept toward
the sound, eventually losing all my dreams of becoming a suspense novelist, but
I did scope out the turtle we spooked earlier.
I rang the gang and since she was close everyone got there fast.
She laid 125 eggs between 23:50 and midnight, and left for Juara Bay
about 70 minutes after that. But this is merely the standard data and numbers
I’m regurgitating back to you all.
Slip slidin' away... to the tune of Paul Simon, duh... |
This night is inimitable for another reason: no tracks existed
because they were covered up by people. When folks showed up they commented on
the absence of tracks too. After she was done laying eggs, we started to poke
around. There were no standard turtle tracks leading up to the body pit, but a
lot of other markings made a nice trail to our female. Zig-zag patterns from
the ocean to her were present. Imagine slowly walking on a beach and moving one
of your feet back and forth, left and right, like the scraggly line on a heart
rate monitor, but vertical instead of horizontal. At the water’s edge a
smattering of footprints existed too, with the zig-zags heading up from there.
Before long we knew what the jig was. Other folks found the turtle
before us and covered up her tracks, with the hope of leaving us in the lurch.
We never see the tracks, find no nest, stop our patrols for the evening and
they come back, dig out the nest and have 125 eggs at their disposal. No other
options were feasible.
The kicker is no one was around when I found the turtle. And
nobody was seen while we hung out in anticipation and then collected the eggs.
After our people-covered-up-the-tracks hypothesis was agreed upon, we all hung
back as Louise covered up her now empty nest. Sitting in a quiet circle, enduring the dead
wind and ravenous sand flies, we chatted quietly about the covered-up tracks. It’s
disheartening to think people, only a couple minutes walk away from JTP, would
so obviously try to trick you so they could take some eggs. Frustration and
dismay were in the air, along with relief that we got the leg up this time. Nights
like this exemplify in bold letters with an exclamation point why our daily beach
patrols are necessary. JTP’s been going for six years and after all its time
here people still want to take eggs next door from us. Conservation work is a
prolonged slog. We obviously haven’t convinced some people a turtles’ eggs are
worth more in the ground than out of it.
![]() |
Her one-way track back to the sea the next morning. I tried getting a photo of the covered up tracks but after so long they just looked like plain ol' disturbed sand. |
Around 00:45, as Louise was still covering up, we heard the “bip bip
bip” sounds of an alarm on a stop-watch. A reminder for the covered-up track
crew that it might be safe to dig out the nest? Maybe. Nobody showed and shortly
after Izati and I sleuthed around with our torch lights to see if anyone was
milling about or hiding. Nothing. Five minutes later though we heard two
motorbike engines rev up relatively close by and head off. Coincidence? Could
be. We’ll never know.
People were thrilled I found the turtle without seeing tracks. Not
me. If we had followed protocol and walked the beach the correct way, Louise wouldn’t
have gotten rattled. Eggs would have been laid much earlier in the evening.
Considering the location of her first attempt the tracks, most likely, would
have remained intact and not become a thing of the past. Saved by sound
tonight? Yeah, you could say that. But I wonder if there are a collection of
past ghost tracks we’ve never found. With tracks being deliberately disguised
on the beach JTP resides on and having already endured our first poached nest
of 2012 in May, it’s going to take a lot more than open ears, and even eyes, to
alleviate the challenges these sea turtles face on their natal beaches. We’ll
gladly take this nest for now, but it just shows the present and future have a
noisy disposition.

Hallelujah for Hatchlings
Alli had been staring at the sand for awhile. It was moving and making some noises here and there. She knew what was going on. I had strolled down to the beach at the end of the work day to take a swim, rest and read some book. I never got around to any of those activities. I then preceded to stare at the sand with Alli for another 30-40 minutes. I then knew what was coming too: hatchling Hawksbill sea turtles! The inaugural batch of 2012.
*** Note: all photos can be enlarged by clicking on them.
The only problem was this was the first time Alli and I had ever been around when the babies make their way up out of the sand. We didn't know if they'd take another 10 minutes or 4 hours. Before sunset for photos? Takeout dinner in the hatchery? Sprinting pee breaks? Vital questions we had no answers for. We were glued to the wiggling sand, continually watching it move about. You could hear the hatchlings rumbling below. Amazingly these tiny creatures (the shell is around 3.5 cm long) can take a day or two to dig out a nest 40 cm below the surface. That don't sound too jolly, but we had a feeling they were bout to hit pay dirt, or in this case, outside air.
For the record: this all took place on 10 May, I've just been a bad chronological blogger and haven't posted it yet. I'll try to be more timely, but one of the things you definitely learn in journalism school: always push the deadline.
Moving on. After over an hour of staring one lil' bugger broke free. Another head poked out, a new flipper popped up and then it was a full-on turtle stampede. Flailing around and scurrying everywhere the hatchlings kept coming, like deranged Black Friday shoppers blood-thirsty for flat screens and video games. I can't undersell the moment. It was frickin' incredible. Watching a boil (who came up with this term!?!) of sea turtles come up like that is a surreal sight. And they just keep coming.
After picking our jaws up and toning down the exciting expletives we kept repeating Alli and I started to transport the babies into a large cooler, counting as we plopped the manic turtles down. Dani and Izati were there too. One cool sight: while the turtles were still in the mesh net milling about, all were trying to get out and go toward the ocean. None were facing land or the jungle!
When all were accounted for 117 had made the vertical journey out of 140 eggs. That's a solid 83% hatching success rate, pretty dang good for Hawksbills. We then measured the length and width of 10 hatchlings and secured them in a huge tub. When you got 6 cats on the premises you need security. In the days that followed another 5 made the journey out and then one loner a few days after that, pushing out total to 123.
These babies came from a nest on Penut, a beach south of Juara Bay we monitor by boat. At 1am that same night we loaded up and headed out to release them. We always release from the location they were found. Some rocky reef was exposed on our walk in even though it was high-tide. These rocks are slippery. I was the one with the cooler full of hatchlings. I was concentrating a lot to not be the late-night dufus that dropped the babies. Nobody likes that dude or dudette.
We got in position. Found a nice spot on the beach. Alli positioned the cooler, tipping it over just enough that they exploded out! Flippers gone wild, maneuvering over sand then rocks, but after that? Only ocean. Into the surf and disappear they did.
The hatchlings were released about 9 meters from the water line. Most of 'em took about 1.50 minutes to get into the ocean. One slow poke (he had some issues moving around a large rock) dragged behind, but after 4.30 minutes even this tortoise in the gang got to the finish line. Our job was done. They made it into the water. Hopefully in 20 years or so they'll make it back.
We did this for awhile. What can I say we were hog-wild for hatchlings! |

Funny Field Work Follies (and the letter F goes wild!)
Field work, just like life, can be spectacular, routine, drab, infuriating or just plain silly. Sometimes when you're on point and luck is rolling the dice with you, I've seen things that have gave me goosebumps. Witnessed events that have caused me to yell out joyful curse words and pump my fist, Arsenio Hall style. A few weeks before we departed I was lucky enough, after following her for 1.5 hours, to watch a Gila monster we were radio tracking dig out a juvenile Cottontail rabbit nest and scarf down some furry youngsters. Incredible. I was on cloud nine for the entire ordeal. That's about as amazing a day you can have in the field.
But then there's days where all you do is sweat and are exhausted, you forget to take a specific data point, leave all the vital gear you need at home or totally just blow it. The key to it all: laughing at yourself when you mess up. A lot. And then making sure you don't do the same idiotic thing twice. I once dropped my keys out of my backpack while tracking a Gila monster at night by myself. Over 3 hours later I found them. Never again have I pulled that move.
That being said, Charlie and I recently spent two nights in a row camping (err, maybe being on a stakeout is a more appropriate term) on Munjur beach in anticipation of a re-nesting Green sea turtle. Hmmmm, I just didn't do any foreshadowing about how this endeavor worked out. Munjur is one of two uninhabited beaches we monitor that are directly south of Juara Bay here. It's probably about a 15 minute boat ride. So let's see: camping near the beach in hope of finding a nesting Green turtle so we can measure the mama and tag her plus get a nest for our hatchery, yup I can get to that. Cue Ziggy Stardust lyrics though: it ain't (that) easy!
The first night started off with a solid sign: two turtles were mating near the beach as we rode in. For the record: JTP's boat is named Will Smith. I would have gone with Jeff Goldblum, but that's another story. We then walked in with our gear and started looking for a place to camp. We chose some ground on the north end of the beach between the high tide line and end of the jungle. More sweet news: an Oriental Whip Snake (Ahaetulla prasina, AHPR) greeted us in the leaves. It's a graceful snake that moves through trees and other vegetation while looking for lizards and frogs to munch on. First time I've seen this one. Only bummer news is I forgot my camera. So all the photos on this blog are from the second night.
Well, hammocks got set up, a small, hidden fire burned, and then Mega-moon came out around 22:30 hours. Talk about bright! The beach was lit up for real, for real. To miss a turtle on this beach would be tough, but alas, we did. As high tide rolled in we got sleepy. Charlie dozed off and I fell asleep for about 10 minutes. After waking up I had a weird feeling of panic that maybe we missed her. So I scampered down the rocks and started walking the sand. The strech in front of us was track free but as I walked up to the southern end of the beach, which of course turtles don't visit too often and you can't see from our makeshift campsite, two sets of turtle tracks were there! One for the way in, the other on the way out. No turtle. No nest. She came up, just like the day before, moseyed around and then headed back to the ocean. I woke up Charlie, we checked out the scene some more, hung our heads in despair as sand flies bit us on the beach, and then decided it's a wrap. We swam out to the boat and got back to JTP around 2am.
Not to be defeated, we were very sure that after coming ashore two nights in a row this mother turtle was ready to drop a clutch on the third night. Back to the camping spot. More jolly times at Munjur! This time I remembered my camera (and binos!), but forgot shoes. Walking on wet coral and rock is not a skill I have mastered yet out here. It took awhile for me to even walk in with our gear. Looking at the photo of low tide you can understand why. Back to the same spot. I had a warm and fuzzy feeling the turtle was gonna show. I searched for more snakes after the sun went down, finding another AHPR in the trees. Then we scarfed some take-out noodles, shot the shit and waited on the tide. The moon came out. No turtle seen. I had a feeling again I needed to get down to the beach. With no red light on (we were being extra careful to not spook the turtle) I made my way and in the first minute I saw tracks on the stretch of beach in front of us. One set. Then noise. Tossed sand and the movement of a flipper. She must be starting to dig her nest! It's always feels glorious when you find what you set out for.
I woke Charlie up and we crept back. She was still flinging sand so after checking out the rest of Munjur we took a seat away from her on the beach. She continued to fling sand. Time passed. Chit-chat here and there. Silence for a little while and then I heard a noise behind us. Holy Toledo that's a turtle heading back to sea. She ran into our cooler we use for the eggs and almost head butted Charlie's backbone. She was on the move and we misjudged her big time! Her nest was layed and she was covering it up when I first saw her. Maybe we should have at least shined some light on her once. We thought about tagging her on the way back, but decided not to. She was ready to get back in the water and make us feel like morons. I couldn't help but laugh. Two nights of camping and no nest collected, no measurements made and no tags placed on her flippers. We laughed a ton and she swam away. I hope she was chuckling too.
Since midnight was on deck and the tide was high we decided to call it, bail on camping and boat back to the JTP. Swimming out to the boat, trying not to slice my foot open in the dark water, I couldn't stop smiling. I knew we'd get the nest in the morning so no worries about that (yeah, Izati brought the eggs back, 98 total). I had to admire how well we succeeded in failing. I think we'll do a few things differently next time. As Will Smith motored back under the night sky I didn't feel too much like he did at the end of Independence Day. Heck, I wasn't even feeling much like Will Smith at all, since he's usually doing everything right and saving the world from imminent demise (ID4, iRobot, Bad Boys, MIB, the list goes on and on). But at least we gave everyone else here something to joke about for awhile.
The female Gila on her way to finding a Cottontail rabbit nest. This is one healthy lizard. |

Low tide, slippery rocks, sharp coral and an uncoordinated Brian make for slug-like walking. But I got no open gashes on my legs so that was a plus. |

The Female Green Turtle Returns!!!
Once sea turtles start laying eggs you can start to narrow down the date when they will return again. Creatures of habit these swimming reptiles are. Lucky us. Knowing the date is coming up round here gets our blood boiling. A large female Green turtle dropped 121 eggs within the first half hour of 14 April. She chose Mentawak beach, where JTP is located, so there's a strong shot she was born here 25-30 years ago since the mommas return to where they were born. This species' renesting interval is 10 - 14 days so starting two nights ago our eyes were wide when we strolled the beach at night.
She didn't come back after 10 days, but on the 11th, she came through! Charlie got the call as we were hopping on the motorbikes after a superb dinner (my belly was bursting with potato curry and peanut chicken) in Juara. Onward we went! By the time Alli and I arrived with the processing gear she was flicking sand out with her front flippers and bout to deliver some eggs. Excellent timing!
Everything played out quite nice-ty (as Bootsy sings). We had a full house in attendance. Besides Alli and I, Charlie, Izati (also full-time at JTP), Ina, Dani (German hatchery intern), another German (his name slips my mind), and Michelle (our new volunteer from Holland) were all there gazing at a huge shell tinged in red light. After she dug the egg hole with her rear flippers (the process looks remarkably like a construction scooper), the eggs started plopping down on the sand. And this time Alli got in there, shoulder deep, and scooped some eggs out (Arizona represent!). She loved it. Having a sticky sea turtle egg fall on the top of your hand is quite the feeling.
All in all this time only 104 eggs total, 17 less than last time. We need to figure out why the number dropped. The eggs are under the sand in our hatchery now. In about 2 months the babies will scurry up. And in 11 days we can expect the momma to return to plop out some more. The nesting season is hopefully ramping up! The more the merrier round here.

Sea Turtle Talk Time, Internet Style
Afternoon people (except most people reading this are sleeping right now). Here at the Juara Turtle Project (JTP) we give a whole lotta turtle talks. On some days when the tourists are poppin' in on a constant basis we give more than a lot, as we can be consumed by turtle talkin' for easily over an hour or two. That's no problem though because most of the time the talks are fun and informative, but in a sense the info can be very depressing with a dash of optimism thrown in, too.
Why depressing? Well, let me give a sea turtle talk to y'all, it's going to be in broad strokes so if you know a lot about these creatures already, sorry in advance for the repetition (you guys can just look at the photos). This is the JTP turtle talk, Internet edition! So there's no way to sugar coat the facts. Sea turtles are in SERIOUS trouble. To put it simply: there just ain't a lot left of 'em in the world's oceans. Only seven species exist and all have the unfortunate status of "endangered" or "critically endangered." Hundreds of millions of Green Turtles (Chelonia mydas) used to swim in the Earth's tropical and subtropical oceans. In 2004, after a worldwide accumulation of data, only about 89,000 female turtles were coming ashore to nest. Male sea turtles never come ashore, only the females, so getting a line on total population #s is rather tricky.
I don't want to ramble on forever about turtles (trust me, I can ramble, anyone who has ever received a voice mail from me can attest to it) so I'll try to keep this post neat and to-the-point. On Tioman Island here we used to get 4 species of sea turtle: the aforementioned Green, the giant Leatherback (the largest sea turtle, they can weigh up to 500 kg, sorry America, we're metric system now!), Hawksbills and Olive Ridleys. As Tom Petty sings, the Leatherback and Olives "don't come a-round here anymore." Luckily, the Green and Hawksbill still do. A reason for the drastic decline in sea turtle numbers on Tioman is that people collected the eggs to eat. People who lived here ate them, as did tourists who came to the island. And they were collecting the whole caboodle so no new babies were reaching the ocean. You can see where this is going: no new babies = very few remaining turtles returning to Tioman. Female turtles return to nest at the site they were born at. Talk about impressive: Tioman turtles will swim to the Philippines and Australia to feed, then turn around and haul shell back here to drop off their next generation.
So at JTP we patrol the beach we live behind on a nightly basis, multiple times per night depending on when high tide is. We look for turtles, or turtle tracks, and if there is a nesting female we collect her eggs and then place them in our hatchery on the beach. We're also patrolling two beaches south of Juara Bay by boat in the morning. After 2 months the babies all come up at the same time and then we release them exactly where we found them. Those cute little flipper happy turtles want to get to the ocean as fast as they can once they're born. If 1 out the 129 Hawksbill eggs Alli placed in our hatchery this morning survive then that's a success. The females drop a lot of eggs, but not many of them make it.
The other threats are everywhere, mostly human-caused. Drowning in fishing nets is a large one (shrimping, long-lining, etc.). Being reptiles these creatures need to breathe so they can only hold there breath for so long (an hour is pushing it to the brink for most species). People still eat their meat (turtle steak used to be a common cuisine) and eggs, and turn their shells into tourist trinkets. Boats hit them, too. Light pollution scares nesting females away, and the ever-encroaching beast known as "development" swallows up nesting habitat every year. Trash in our waters gets mistaken as food: plastics bags look like jellyfish, cigarette butts are the shape of a floating snack.
Bam! Have I got you depressed yet? Sorry, the numbers are sobering and like I said, trying to sugar coat deep fried gruel is tough. But here at JTP we're trying to help out as much as we can. We patrol the beaches, collect the eggs and get as many babies in the ocean as possible. We are working on sea turtle friendly lighting for the nesting beach in front of us. Protecting nesting habitat is also on the docket. Education and outreach is always important. We are open to the public, and like I said before, we give a lot of turtle talks on a daily basis. And working with the fisheries department and the marine park around Tioman is a priority as well. A postive side to all this: communities and organizations that have continually collected eggs and released them for 30+ years (coincidentally how long a lot of species take to reach sexual maturity) have seen nesting increases. That's more turtles on the beach mon. It takes time to turn things around, but it can be done.
So what can individuals do? I'll touch upon this in another post as I believe I have broken my own goal, and have rambled on for a quite a bit. But remember: it isn't just about sea turtles. A striking number of species face extinction in the ocean, from huge sharks to smaller ugly fish (the Monkfish anyone?) The hope is since sea turtles are sexy charismatic megafauana (for instance: not many people hate on sea turtles, but folks sure do hate rattlesnakes) people will not only get involved to help their seven species, but the smorgasbord of other marine life that faces a continued battle to not blink out before my generation passes. Thanks for reading and if you have anyone questions about all this (and I know it's a lot) please do ask me or Alli.

What Green Sea turtle tracks look like. We look for these on our nightly walks. These tracks are from the above female in the photo laying eggs. |

That's a lot of dead turtle on the line. Unfortunately this happens all too often. Another photo of a photo. |
Enlarge this photo to read. It's a great summary of the problems sea turtles, and a lot of marine life, face. |
