Frog Survey Team Assemble!!!

Hey, Mark here again.

It has been a little while since the survey team has let everyone know how we have been doing but don’t worry, we have been nice and busy. We have been conducting out normal surveys in fun and exciting places, such as Morne Bleu Ridge, the highest point you can drive to on the island! Our normal work is great, but last week we had especially good fun. We have been planning a mass capture of Trinidad Stream Frogs -Mannophryne trinitatis at Lopinot and we finally got the time to conduct it.

The mass capture involved taking a team out and catching as many frogs as we could for 2 hours in the morning (10-12) and 2 hours in the afternoon (3-5), as these are the prime catching periods. After we had caught a batch of frogs we would bring them back to the lab and process them, taking photos and measurements of weight and body length. I was present at every capture and therefore had a very busy day; getting about 30 minutes to get lunch before heading back out.

After conducting the capture for three and a half days (14 hours of catching), we amassed an astonishing 91 frogs, substantially more than we had expected. After keeping the frogs for a couple of days in case we needed to collect any more data, we were ready for their release. We wanted everyone to see some of the release, so we made a little video. Take a look.

I hope you found it as interesting as we all did.

Bye for now, Mark.

Ten weeks of field work completed!

That’s our Expedition over for this year! Though plenty of work to do when we get home on the 6th September.

We have all had a fantastic life changing experience – luckily we still have ample tales and photos to share with you and ofcourse the findings from all the work we have done.

We will be out of touch for the next three weeks celebrating and relaxing but please keep in contact over the Autumn when we will continue to write.

Peace and love

Rio Seco Waterfall Trip

It was time for a break from field work and an escape from the lab!  On this day trip we all drove North to Salybia where a short hike through the jungle brought us to the panoramic scene you can see above. A turquoise lagoon surrounded by towering trees and birds swooping over head. As we swam in the pool, shoals of fish nibbled at our legs. We were lucky to have this paradise all to overselves after working hard all week! 

El Tucuche: The Quest to Find the Golden Tree Frog

The second highest mountain of Trinidad, El Tucuche of 936 meters above sea level, lies in the Northern Range close by our home. Our adventure was to seek out the elusive Golden Tree frog, Phyllodytes auratus, which is endemic to 2 mountains in the whole world!  We prepared ourselves for a brutal hike through the jungle in high humidity as we set off at 8am through the Maracas Valley to the foot of the mountain. Well equipped, we trekked up the rocky, crystal quartz filled path, accompanied by expedition friends Mike Rutherford, Steveland Charles and Reptile Enthusiast – Adam.

The steep incline proved to be a mental and physical challenge, but comforted by the knowledge we had survived the Ben Nevis climb earlier in the summer, we powered through! The path soon became a tangle of tree roots which we crawled over. The fauna changed drastically as we ventured higher up the trail. Leaving the invasive bamboo and young saplings behind and moving deeper into the forest where native bamboo surrounded us and vines hung like curtains from the towering ancient trees. An assortment of coloured fungi scattered the trail – bright oranges, coconut shell like ridges and small yellow primrose shrooms. Sharp razor grass and ferns grew in abundance and hairy lichens and moss drooped from the trees as we reached the fresher air.

Fallen trees blocked our path which we hurdled over or crawled under. The trees dwindled to few as we emerged out of the canopy, to see we were higher than the surrounding hills. Close to the peak, we walked through the clouds – the rain started to pour, cooling us down. We reached the summit before we knew it – Though we could not see much but the clouds, bushes and wild green and purple orchids! After collapsing and having some jam sandwiches we celebrated in true Trini Family style by creating a pyramid – Becky, who is now home, we left space for you on the top of our tower!

Feeling accomplished for reaching the top we set out to find the Golden Tree Frog who lives in the water tanks of the giant bromeliad, Glomeropitcairnia erectiflora, which thrive on the tree trunks and branches.  As we were soon to discover they are home to a range of beasties… Our chances of finding the Golden Tree Frog were slim, as the species is critically endangered and rarely reported in its only habitat on the peaks of the El Tucuche and El Cerro del Aripo. We had previously been permitted by the Trinidad Wildlife Division to collect samples from El Tucuche. Using gardening gloves for protection we dissected 20 Bromeliads and found one Golden Tree Frog (!),  3 tadpoles and a teeny Flectonotus fitzgeraldi  frog in total. This was alongside many a deadly scorpion and centipede. Tityus trinitatis scorpions rushed out from between the leaves of the bromeliad – when stung by these critters they inject a toxin into you which causes pancreatic degradation…

The walk home was easier for some and trickier for others – we recommend sliding down the hill on your bum! More photos to follow!
