In many parts of the world, frog populations have declined drastically since the 1950s. Amphibians, particularly frogs, are thought to be excellent biological indicators of ecosystem function because of their location in the food chain, their permeable skins and their typically bi-phasic life (in both water and on land). Although habitat loss is certainly one of the most important features of most declines; pollutants, climate change, introduction of non-indigenous predators/competitors, and infectious diseases have also been implicated.

Measuring and monitoring changes in frog species diversity, lifecycles and population densities will provide comparative data to help measure the impact of different human activities on local ecosystems. In particular, a study of frogs will provide valuable information in relation to the health of aquatic systems, which play an intrinsic role in rainforest habitats. Frogs are delicate creatures that can provide an early warning for endangered ecosystems.

Frogs play an essential role in the food chain of many ecosystems. Not only do they consume large quantities of insects, but also provide a valuable food source for birds, fish, and other animals. The importance of frogs to tropical ecosystems and the potential of frog farms to provide both tourist attractions and a breeding ground for frogs to sell in international markets are concepts that will be included for study in the CREES Ecology Club's weekly classes at the MLC.

Stage 1: Background Research & Species Selection
Identification of frog species diversity, population sizes and population structures in the Fundo Mascoitania area, will provide the background information for selecting which species to breed and study in the Frog House.

Stage 2: Frog House Design & Construction
A suitable location will be selected within the gardens of the MLC to replicate the ideal habitat conditions for frogs within an enclosed space. The location will be cool and damp to mimic their normal habitat.

Stage 3: Observation & Sample Collection
Observation of selected frog species in their natural habitat to understand territorial issues, activities and identify food sources followed by the collection of tadpole eggs and frogs from around Fundo Mascoitania for transportation to the Frog House.

Stage 4: Development & Coalition of Data
Species will be monitored within the Frog House and data recorded in relation to lifecycles and feeding habits. An index of Frog species found in Fundo Mascoitania will be compiled and a card index for species identification in the field will be created.

* Please note that as many frogs are nocturnal, much of the research, especially the study of frogs species within their natural habitat, will be carried out during the night.

Volunteers can assist the Project Manager and Resident Naturalists in all stages of the Frog House Project.

In the event that volunteers have skills that are specifically applicable to the project, the Project Manager will seek to apply them appropriately.

There are a number of tasks involved in most elements of the Frog House Project that volunteers can get involved in regardless of prior knowledge and experience.

Necessary training and supervision is provided.

Involvement in the project as a volunteer is subject to the statutory one-month minimum stay at the MLC.
