Amphibians play a vital role in the ecosystems where they are found. Ten anuran species are currently known to occur in our study area, some of which occur in relatively high abundances, even during the long dry season. Data for this project will be obtained by surveying rice paddies, ephemeral and permanent ponds and lakes; recording all encounters; noting the species, the number of individuals and the specific details of the immediate habitat where the animals are found. All data collected will be used to create a monitoring system for future studies whereby the species composition at each water body can be monitored. In addition, this project can be used to begin to assess the impact of the invasive ‘Tiger frog’ Hoplobatrachus tigrinus on the otherwise endemic community.
Madagascar boasts some of the most spectacular biodiversity in the world: lemurs, tenrecs, baobabs and over half of all known chameleon species. Much of this biodiversity is endemic. The Operation Wallacea surveys are completing research on the dry forests and associated wetlands of Mahamavo in the northwest of Madagascar.
Madagascar has declared 17% of its land as protected areas, but much of this land is already severely degraded, so the actual area of land under protection is much smaller. An alternative approach to assigning protected area status and prohibiting usage, is to develop community managed areas such as Mahamavo, where there is a mosaic of protected and managed areas. DTZ, the German Technical Support Agency has established a series of community managed forests in the Mahamavo area that appear to be successful and may form the basis for conservation and improving livelihoods in other parts of Madagascar. The Opwall teams here are monitoring how the forest structure and biodiversity in these community managed forests are changing over time to identify whether this management strategy can provide a viable alternative to national parks in terms of protecting biodiversity.
The dry forests around Mahamavo have exceptional diversity with two species of diurnal lemur and another five to six species of nocturnal lemurs, two spectacular species of chameleons, three known species of leaf-tailed geckos, and many endemic birds. In addition to the forest work, the Opwall teams are also documenting the biodiversity value of the adjacent wetlands with a view to getting this area upgraded to Ramsar status (a Ramsar Site is a wetland site designated of international importance under the Ramsar Convention).
In Madagascar it is the dry season so it is hot during the day (temperatures between 25 and 30 degrees Celsius) with extremely little chance of rain. During the evenings the temperature does drop to around 18 degrees Celsius with occasional cold spells getting as low as 14 degrees Celsius.
Fitness level required
Moderate. This project requires you to walk long distances, and although the terrain is relatively flat you will be walking mostly on sand which can be tiring.
Facilities are basic (tents, bucket showers, long drop toilets). The site has no phone signal or wifi.
