Field sampling from Maracas Valley!

Sorry for the long delay. We have been hard at work in Trinidad over the last few months and I would like to share with you our progress. We have had many good adventures and we have many more to come. First, with a group of national and international students from Trinidad's University of the West Indies, we ascended to a high pass between two large mountains. On the trail is a sign that tells hikers that they are on their way to the second highest peak in Trinidad, El Tucuche. On that mountain lives the golden tree frog. The sign had fallen down and had been taken over by the jungle.

Above, you can see Dan tying the sign to a tree with the only rope we could find, which happened to be a nice piece of vine! Thumbs us Dan!

As we walked up and up the mountain, we often spread out along the "tail", each of us looking for unique plants and animals. Some of us blend in better than others... Look at Elsa hiding in the back!

The hike was steep at the top and the steps became difficult as the rain started falling. 

As we reached the last few hundred feet of mountain, we finally started seeing the giant bromeliad seen in the picture above.  This tree, one of the few with the giant tank bromeliad and possibly the golden tree frog, was perfect for climbing. As you can see below, I was very excited.

Our next step was to climb the tree and find ten bromeliads from which to sample. Dan and I ascended into the canopy to take water samples from the Bromeliad's leaf whorls.  The tanks of water the frogs call home were full of rain water. We safely got our ten samples and spent some quality time enjoying the view from above. We look like birds in a nest!

Again, thank you for your support. I will keep taking good pictures to share with you all. Our next field efforts on this project will be towards the end of November and early December. Currently the samples taken on this past trip are in the lab at Washington State University. It will take a while to get results back, so in the interim, we return to the field. Cheers!

About This Project

In two isolated "sky islands" on the island of Trinidad live an IUCN critically-endangered species, the golden tree frog. We know little about the golden tree frog, so it is very difficult to help protect this rare species. It is nationally and internationally recognized as threatened and important for conservation and cultural reasons. To understand this endangered species we need to develop two new non-invasive methods to study them: environmental DNA (eDNA) sampling and vocalization surveys.

Blast off!
