Frogs in Trouble

Our frogs are in trouble.

 

One third of amphibian species are on the brink of extinction with an estimated 120 already gone! Many species are still being discovered today, but many will become extinct even before we knew they existed. Many palaeontologists believe that the earth is about to experience its next mass extinction with frogs following the disappearance of dinosaurs.

Frogs place a very important part in the food chain, both as predator and prey.

Climate change, pollution, the use of harmful pesticides and over collection are all contributing factors, but habitat loss and a parasitic fungus amphibian chytrid are the biggest threats.

The iSimangaliso Wetland Park has the highest number of frog species in southern Africa. Protected areas like these parks are crucially important to the survival of many of these species. Urban and rural developments, forestry and agricultural practices are causing rapid losses of habitat.

Listed Below is some of the frog species that are rare, threatened or endemic that has been recorded in and around St Lucia.

    Hi, What type of frog is it in your main pic, as I have had one that recently had babies and has been at my place for about 5 years now?
