The Beginnings of an Amphibian's Project!

In January 2010, GVI began the Biological Assessment and Incidental Sightings Projects to collect data regarding the abundance and diversity of animal species belonging to the four classes of: Amphibia, Aves, Mammalia and Reptilia. A secondary aim of the Biological Assessment Project was to determine if the data collected could be used to develop new, more class/species specific projects.

Since their inception (using data compiled from both projects), a total of 26 species of Amphibians have been identified within the area of Tortuguero National Park surveyed by GVI. These include 1 Caecillian, and 25 Anurans (3 Toads, 22 Frogs): many of these have been seen only sporadically and only a handful are recorded regularly.

It became apparent that after many night walks over several weeks, between May and July 2012, that there is a very diverse amphibian population residing in the Jalova area; which have the potential to be seen more often if regular surveys occurred. This thought, along with a desire to further understand how each area of forest effects the species found therein, prompted the creation of the Amphibian Project.

This project has two aspects: the first involves surveying various sites at night, all of which differ in their ability to retain water during the wet season - water being crucial at some stage (or all) of the life cycles of all Amphibians. The second involves gathering data on the morphology of individuals and the area they are found. This information is collected during the night and day to gain information on both nocturnal and diurnal species.

In the past 3 months, GVI has seen an increase in the number of Amphibian species recorded on a weekly basis. This includes species which have never been recorded by GVI before, such as the Boulenger’s Snouted Treefrog (Scinax boulengeri), as well as species which are rare due to extremely small ranges, such as the Tawny Treefrog (Smilisca puma) With continuing surveys it will be interesting to see if such species will be sighted more often. This will also give us more insight into where and when each species is likely to be present. It is also hoped that with the data collected from this survey, GVI will be able to further understand the differences between the habitats types.
