Welcome to our blog,
FROGS ARE GREEN!

For over 200 million years, ponds, marshes, grasslands, and rain forests have come alive with the calls of frogs. Yet these remarkable and colorful animals are declining at such a rapid rate that they are being called the Earth’s next dinosaurs. According to the IUCN Red List of Threatened Species, a third of the world’s amphibian species are threatened with extinction. To read more, click here!

Amphibian Ark Exhibit Opened at Paignton Zoo

Thursday, August 5th, 2010

If you live in England or are visiting England this summer, you might want to hop over to the Paignton Zoo, which yesterday  launched  the Amphibian Ark exhibit, The event was hosted by actor and musician Anthony Head (the cool Rupert Giles in Buffy the Vampire Slayer).

Here’s some info from the zoo’s website (edited):

Amphibian Ark will be home to 14 amphibian species, including the blue poison dart frog, the phantasmal poison dart frog, and the Anderson’s axolotl. Staff have also been working with relatively common species to perfect husbandry routines and protocols before taking on endangered amphibians.

Mike Bungard, Curator of Lower Vertebrates and Invertebrates at Paignton Zoo Environmental Park, said: “I’m very pleased – the facilities are excellent. We have a large, flexible working space with on and off-show animal care areas, the capacity for high level bio-security and a state-of-the-art water treatment system. The water garden links the exotic amphibians indoors with the idea of domestic garden conservation.”

Out of 6,000 known amphibian species, 50% are threatened or endangered, compared to 10% of mammal species. Amphibians are affected by habitat loss, climate change, pollution, pesticides and the deadly chytrid fungus. Unstoppable and untreatable in the wild, the fungus can kill 80% of amphibians within months. The aim is to protect species from the fungus, possibly by taking animals from the wild and then reintroducing them when it is safe to do so.

It’s hoped that Amphibian Ark will inform and inspire visitors, breed rare species, and become an internationally recognised training facility for herpetologists. Staff have launched two field conservation projects in the last year in Tanzania and Trinidad.

The zoo is close to Torquay (in Devon), which is accessible by train, and from Torquay you can take a bus  to Paignton.

Cape Town’s secretive inhabitant and pilot conservation species – the Western Leopard Toad

Monday, June 28th, 2010

Written by Guest Blogger: Mark Day

Dusk ascends to cover the suburb of Bergvliet under a blanket of darkness. It brings with it the chill of a Wintery August night in Cape Town, South Africa, as a nippy breeze sweeps across the small urban wetland of Die Oog (an Afrikaans word meaning “The Eye”).

This man-made depression was originally dug out some 284 years ago to provide water for livestock on the neighbouring farm of Dreyersdal. In more recent years, however, Die Oog has come to serve a much greater purpose, as a pivotal breeding site for one of Cape Town’s most threatened amphibians, the western leopard toad Ameitophrynus pantherinus.

As little as six years ago it was thought that only several such breeding sites remained in existence, for a species which has suffered massive population declines as a consequence of numerous threats including urban expansion, habitat destruction and population decimation through road kills. Today, conservationists and scientists with the aid of concerned volunteers and the public have listed a total of 52 breeding sites within the Cape Town range of the species. Further eastwards, some 150 kilometres away from southern Cape Town, a largely unprotected population comprising seven breeding sites exists.

Unlike most frogs which remain at water courses throughout the year, toads live in what’s termed ‘foraging areas’ where they lay dormant by day and hunt by night—with an exception for August month and there about when they migrate to and from local aquatic environments to breed. Presently, the majority of these foraging and breeding areas fall under urban suburbia, guaranteeing a window of constant interaction between these toads and the unknowing dangers their human neighbours pose.

Despite current conservation action and volunteer efforts to protect the Cape Town populations, census data from the 2009 breeding season only generated a recorded 1125 live migrants and 258 dead. Great strides have been achieved in recent years through a consistent increase in awareness of the plight of the species and in the recruitment of volunteers. The fate of the species is however uncertain—unless the citizens residing in these areas value their endemic and endangered leopard toad, there will merely remain stories of its once enigmatic nature and quiet existence.
