Due to limited spaces on the forest research programme in some weeks, the forest only options in Honduras are available as either a 2 or 4 week period. There are also 4 week expeditions available which combine both forest and marine components consisting of either 2 or 3 weeks forest and the remainder marine. If you want a marine-only project then you can book an expedition of 2, 4, 6 or 8 weeks and choose from the marine expeditions below. Please read the expedition options below and then move to the descriptions of the constituent parts for further information.

Constituent parts: Training Courses

HO001 Neo-tropical Forest Ecology and Jungle Training

Series of lectures and practicals designed to ensure your survey skills are accurate, well-informed and that you can work safely within a field environment.

Canopy Access Experience (available throughout HO001)  Canopy Access Limited, the team that helped David Attenborough ascend into the canopy for Life of Mammals, Life in the Undergrowth and Planet Earth series.  The team will be at Base Camp running a half-day course on safe ascent into the canopy. The course can be done as part of the jungle training and will show you how to ascend 40m+ into the canopy along with a qualified instructor. This optional experience costs US$170 or £110 – just pre-book with Canopy Access Limited via their website: http://canopyaccess.co.uk

HO002 Expedition medicine experiential course

This course in expedition medicine covers pre-expedition planning, medical emergencies and trauma in the field, tropical infections and snake bite and envenomation procedures. The course is delivered as a series of lectures and practical exercises.

HO004 PADI Open Water Dive Training

This course involves a combination of theory lessons, confined water dives and open water dives to gain an official scuba diving qualification.

HO005/006 Caribbean reef ecology and survey techniques – diving / snorkeling

The course consists of lectures and in water practicals and teaches identification of common genera and species of coral and other macro-invertebrates, identification of the major reef-associated fish families and common species. Designed to introduce a variety of methods and practices used for scientific research in the marine environment.

HO008 PADI Open Water Dive Training

If you are already qualified as a PADI Rescue Diver and have at least 60 logged dives you can complete the PADI Divemaster training. Divemaster training has to be done as a full time commitment so you won’t have the chance to join the research projects on this option, although you will be learning to supervise students completing diving for research. An advantage of completing the course with Opwall is the opportunity it gives you of joining the programme as a Divemaster staff member at any of the Opwall sites worldwide in future years.

Optional Additional Dive Training

If you are already dive trained, you can sign up for additional dive training in your spare time. These courses include PADI Advanced Open Water (US$220) and PADI Rescue Diver with EFR (US$400).

Details of Projects and Expeditions 

HO003 Monitoring Biodiversity Change

Operation Wallacea has established an annual monitoring programme for Cusuco National Park. This involves standardised monitoring of a number of taxa from standard sites and transects across the park to assess changes in the structure of the forest and how these changes are impacting the target taxa. Cusuco National Park is now the most published and best studied park in Honduras, so joining these teams will give you the opportunity to work with a large range of scientists across a series of camps and habitats.

Students assist all research projects including:
• Helping to set up and empty invertebrate pitfall traps to assess dung beetle communities, light traps for moths and jewel scarab beetles
• Performing timed searches for herpetofauna (reptiles and amphibians)
• Point counts and mist netting for birds, recording data and taking biometric measurements
• Habitat monitoring by completing forest structure plots
• Setting and emptying small mammal traps
• Patch occupancy and camera trap surveys for large mammals
• Mist netting and sound recording for bats

Additional studies include projects such as:
• Surveying epiphytic lichen diversity across different forest habitats in the park
• Determining territory size and bird behaviour using call back
• Examining invertebrate communities in bromeliads and looking at infection rates of chytrid fungus (a disease that has decimated amphibian populations elsewhere) in these tiny mountain top amphibian communities to determine the best strategy for their conservation

HO007 Marine Research Assistant Pool

Our team of scientists conduct a wide range of research projects at our sites on Utila and Tela, ranging from those involving in-water surveys to laboratory based studies. These projects require help with data collection and analysis, students in the research assistant pool will have the opportunity to experience multiple research projects.

Projects include:
• Stereo-video: Ecosystem monitoring using stereo-video fish surveys and benthic video transects
• Sea urchin population dynamics
• Invasive lionfish ecology
• In-situ behavioural studies of cleaning symbioses
• Laboratory behaviour studies of urchins and invasive lionfish
• Mangrove system ecology

At a weekly research assistant meeting, the science team present their research and what assistance they require that week, and research assistants sign up to one or more projects accordingly.



Accommodation at Base Camp is in tents and there are toilets and showers. There is a wireless networked computer system with an internet link at Base Camp (although access to the internet will be limited) and this is where all the data from the various survey teams are collated. In addition, there is a field DNA lab. From Base Camp, teams can access four core zone fly camps across the park, giving the experience of living deep in the forest, sleeping in hammocks or tents and with the river as your shower facility. Terrain in Cusuco is the toughest of all our expeditions.



Located outside of Utila town is the Coral View hotel, situated between some of the best reefs and the largest mangrove-lined lagoon system on the island. Accommodation is in shared rooms and is run by a local Utilan family who have built, in conjunction with Operation Wallacea, a well-equipped dive and environmental monitoring field lab. The home reef can be accessed from the jetty by snorkelling or diving and provides a site for more intensive experimental research.


The Bay of Tela is situated between the national parks of Punta Sal and Punto Isopo. Honduras Shores Plantation is located on the beach in the Bay of Tela between the sea and a small lagoon which connects to some of the larger lagoons in the area. Accommodation is in fan cooled dormitory style rooms. There is a small dive centre with newly built lab facilities, a swimming pool and lecture facilities. All diving is by boat, with mangroves reached by a combination of kayaks and a small boat.
