Mona Island Amphibian Expedition | Field Projects International

Mona Island Amphibian Expedition

Program Overview

Situated in the heart of the Caribbean, equidistant from Puerto Rico and the Dominican Republic, Mona Island is often called the Galapagos of the Caribbean. Once just a destination for pirates and privateers, Mona is protected by the Department of Natural and Environmental Resources (DNER) and special permits are needed to access the island.

The Island is home to 16 incredible species of amphibians and reptiles, of which 92% are endemic, meaning they are found nowhere else in the world. The preeminent goal of this week-long expedition is to document as many of these species as possible, and compare records with those last collected in 2015. In lieu of climate change, and recent catastrophic weather systems, such as Hurricane Maria, this expedition will provide a much needed update on the conservation status of several species.

Stepping onto the shores of Mona is like taking a leap back in time, before modern human development played a role in species interactions and obstructed our view of the natural world. The island is an untouched heart of the Caribbean Sea. Records of Pre-Taino culture, potentially the Casmiroids, inhabiting the Mona Passage date back to 1000 BC. The Taino are descendants of the indigenous South American and Caribbean Arawak and named the Island after their Cacique or chief who was called Amona.

This program is ideal for those with interests in herpetology and a willingness to endure bare-bones field conditions. This is a special program that will not be repeated annually or even biannually. Should you apply and be selected to join, the sunset will be yours to share with only the island wildlife. With zero light pollution, the stars are abundant. You’ll fall asleep to the enchanting call of the Mona Coqui frog, and wake up to the roaming iguanas and majestic Caribbean sunrise.

This program appeals to people with an interest in Animal Behavior, Herpetology, Conservation Biology, Zoology, Environmental Science. Specific training is provided in animal handling, health assessments, morphological measurement, environmental data collection, spatial analysis, population surveys, and wilderness trekking.

Jennifer Stabile began her career as the reptile keeper at the Central Florida Zoo (CFZ), and soon developed a long-term partnership with Dr. Rafael Joglar at the University of Puerto Rico to preserve the island’s emblematic coquí through the establishment of captive colonies, staff exchange programs, education, and outreach.  She also worked with the Florida Wildlife Commission Research Institute (FWCRI) on tracking emerging amphibian pathogens, and more recently she was Director of Conservation at the San Antonio Zoo where she helped develop their Research and Conservation Center. While there she also pursued research partnerships with the University of Texas and the Gladys Porter Zoo to assess the relative abundance of the Black-spotted Newt. In 2016, she accepted a role as editor of the conservation section of Herpetological Review, and has been elected to serve as president of the International Herpetological Symposium (IHS).

For our brief stays in San Juan, the group will be lodged in a standard hotel and we will taste authentic Puerto Rican food in a nearby restaurant. Exact details on the hotel can be obtained 2 months prior to the start of the expedition.

On Mona, basic camping equipment will be supplied, and we suggest you bring your own light sleeping bag or a light sheet for additional comfort. A chef will accompany the expedition crew to Mona, and three meals a day will be provided, along with plenty to drink. Most dietary restrictions on Mona can be accommodated, so long as we have advance notice. 

Air travel: Getting to Puerto Rico is accomplished by air. We recommend using Kayak, Orbitz or Expedia to book your flights online. Please do NOT book flights until May 1. The expedition will be held from July 7th to 13th, 2019. This means that you should plan to arrive in Puerto Rico on July 7th or early. Your return flight should depart from Puerto Rico anytime on July 13th. 

Car travel: If you have never visited Puerto Rico before, this trip will be a real treat. To get from San Juan to our port of departure, Cabo Rojo, we will drive the entire island from East to West. The ride through the interior mountains and forests of Puerto Rico is particularly beautiful.

Boat travel: We will take a small boat to Mona Island, the trip can take between 4 and 6 hours depending on ocean conditions. No matter what, the trip will be wavy, and we advise you to carry something for sea sickness, unless you are already acclimated to small boat rides.

If you choose to stay on in Puerto Rico before or after the program, you may. We can provide hotel recommendations for you. Please note: For this expedition, there are no options to arrive slightly late or depart slightly early, as our boat to Mona will only make the round-trip journey one time.

Frequently Asked Questions

If you don’t find the answers you are looking for below, please contact us.

Can I get credit for participating in this expedition?

Participants must inquire of their own colleges or universities whether they can be awarded credit for participating in this program. This is a research expedition, and as such, some institutions may be able to offer research credit hours through faculty members. If you need additional information from FPI to pursue this option, please email Note, you incur a small, nominal charge from FPI if your participation requires special evaluation or reporting from our program leaders

Why else join this expedition?

To list a few reasons:

  • Opportunity to conduct the first Coqui population survey since Hurricane Maria.
  • Exploration of an uncultivated and uninhabited Caribbean island
  • Downtime on pristine beaches, camping under a spectacular sky
  • Building new relationships with enthusiastic and expert herpetologists
  • Experiencing what island fieldwork is like


Do I need a visa?

Every country has different requirements for visitors, depending on their citizenship. Foreign nationals are required to have a valid passport, visa, or green card to enter the country.  To find out what regulations apply to you, please contact the US consulate in your home country.

What should I bring with me?

Download a packing list here. Please read sections below for explanations for each item as well.
What's the lowdown on footwear?

Hiking boots are required on this course.

A pair of sneakers or hiking sandals will come in handy during your travels and for use while at base camp. We strongly discourage bringing flipflops as they take up space and are useful in very limited situations.

What kind of luggage should I use?

Suitcases or duffel bags are fine, just make sure you are able to personally carry what you bring without assistance.

What do I need on the island?

The most important things you need in the field that will NOT be provided are your day pack, a water bottle, sunscreen that is “reef safe”, hat, sun glasses, swimsuit, rain jacket/poncho, flashlight. Additionally, binoculars, camera, and a digital watch can be useful. Check your packing list for more details.

You will not need warm clothing on Mona.

What about battery-operated equipment?

You will need a battery-operated headlamp, or flashlight.  Headlamps are convenient because they are hands-free. If you’re interested in seeing wildlife at night, bring a bright light. We also recommend a small battery or solar operated fan, as it gets very hot at night. You must bring your own batteries for your personal electronics.

Do I need a watch or alarm clock?

Yes, we recommend you have one, or both.

What is the weather going to be like?

Weather on Mona is HOT (temps can reach over 100F), and tropical storms may be present. It does not cool down much at night, so be prepared, you will be sweating. We do recommend trip insurance in case of a hurricane, which would result in a canceled expedition.

What medications should I bring?

The program does not provide any medication to participants. As such, you must bring what you might need.  These items could include:

– A course of broad-spectrum antibiotics (ciprofloxacin is a common and effective one)

– A course of antibiotics for digestive trouble, and a small number of pills of Immodium (to be used in emergencies only)

– Electrolyte/rehydration packs (hint: the juice flavoured ones are much nicer than the medical ones)

– Anti-fungal cream/powder (effective on yeast), particularly if you are prone to these infections

– Anti-itch medication: over-the-counter lotions are ok

– Antacids to comfort your stomach

– Band-aids, tweezers

–  An Epi-pen if you have any serious allergies

– Antihistamines to be taken in case of mild allergies (something like Claritin/ Zyrtec)

What vaccinations do I need?

You will have to provide proof of a regular vaccination record (as listed here by the CDC). There are no special vaccinations required for this expedition.

What about health and safety?

We take the health and safety of all participants very seriously.  We look out for each other and take care of our team. Our field sites have stringent protocols on safety procedures in the case of an emergency that we are obliged to follow. For specific emergency protocols, please contact us at

Neither the field station nor Field Projects International will be responsible for costs associated with medical emergencies. Before being accepted to the program, applicants must submit a brief medical history evaluation. This is not meant to discriminate against people, but instead to protect them from being in a situation where they are at a severe or life-threatening disadvantage.

All participants must sign a participation contract, without which applicants cannot participate in our courses or research programs. We make special references to an alcohol policy in our participation contract – we have a zero tolerance policy at the field stations. You will also sign a sexual and gender-based misconduct contract (and so will all supervisors). This is not to suggest that this issue is, or has been, a problem at our field sites. However, there has been a large amount of reporting on these matters in the press of late, and we want to assure you that we take any such violations extremely seriously. We want our participants to be as safe and comfortable as possible.
