The effective conservation of Cusuco National Park is imperative for many endemic species, none more so than cloud forest amphibians. The spread of chytrid fungus has caused severe declines in many amphibian populations and is a major concern for global amphibian conservation. Chytrid is known to have been present within the amphibian populations of Cusuco for at least 15 years, but its prevalence within specific areas of the forest and the extent to which different species are affected are not well known. Amphibian species will be encountered during diurnal and nocturnal transects and swabbed for chytrid. Swabs will be taken back to the lab at base camp and tested for the presence of chytrid using polymerase chain reaction (PCR) and visualized using agarose gel electrophoresis. Individuals will also be assessed for visual signs of infection. Prevalence of chytrid will be mapped in the Park using multiple years’ data to assess whether the disease is continuing to spread to previously uninfected areas to contribute to the investigation into the underlying mechanism of infectivity.

Extended Dissertation Summary

Honduras Terrestrial Research Objectives

The forests of Central America are some of the most biologically diverse forests in the world, partly because they are the meeting point of two great faunas – those from North America and those from South America which had evolved separately. Many of these ecosystems have been badly degraded but there is a proposal to join currently discontinuous areas of forest into a continuous Mesoamerican forest corridor running from the Yucatan peninsula in Mexico (where there are other Opwall teams) to Panama. Part of this corridor will encompass the cloud forests of Cusuco National Park in Honduras – a site rich in endemics and endangered species yet threatened by unchecked illegal deforestation.

The Opwall survey teams have been working in Cusuco since 2003 and the data produced has resulted in the Park being listed as one of the top 50 most irreplaceable protected areas in the world (based on a review of 173,000 sites worldwide). As well as underlining the biological value of Cusuco, the datasets collected by the Opwall teams are also being used to make an application for funding through Natural Forest Standard (NFS). This will allow carbon credits from the Park to be issued, which can then be sold to multinational companies wishing to offset their carbon emissions and at the same time help protect biodiversity. Funding obtained in this way will then be used to manage and protect the park and the many unique species it supports.

  • Develop an independent research project and write a formal proposal
  • Attend lectures and field based practicals on Neotropical forest ecology
  • Learn how to live and work safely at a remote cloud forest research site
  • Take swabs from amphibians for genetic screening of chytrid infections
  • Use polymerase chain reaction (PCR) to process swabs to test for the presence or absence of chytrid
  • Map the prevalence of chytrid in Cusuco National Park using multiple years’ data
  • Learn how to organise and analyse large data sets
  • Opwall fee
  • Cost of international flights into and out of San Pedro Sula
  • Cost of internal travel to and from the start and end point of the expedition, plus any hotels you might require. This costs around £133 or $193 on average. Extra nights’ accommodation in San Pedro Sula costs around £49 or $71.
  • Park entrance fees – £17 or $25
  • Vaccinations and prophylactic medicines – cost can vary depending on your healthcare provider.
  • All prices in GBP or USD unless specified

Climate
In the cloud forest of Cusuco National Park it can get warm in open areas (temperatures up to 20 degrees Celsius) but much cooler in the shade of the forest. Overnight the temperature can drop below 10 degrees Celsius at higher altitudes. It rarely rains in the morning but it regularly rains late in the afternoon and overnight.

Fitness level required
Medium – High. You will need to hike from camp to camp for up to 5 hours over steep terrain with your backpack.

Creature comforts
Facilities in Cusuco are very basic (tents, hammocks, river showers, basic trench toilets). There is no cell phone signal in Cusuco National Park and very limited satellite internet available through a communal laptop at Base Camp.
