Get Us Out of Here!

Giant Ditch Frog (Leptodactylus fallax), Critically Endangered

The Giant Ditch Frog, also known as the Mountain Chicken by locals due to its size and the taste of its flesh, is confined to two small islands in the Carribbean: Montserrat and Dominica. Although it used to inhabit several other nearby islands, it's total current range on the two islands is less than 50 km squared.

What caused it's decline? Environmental factors such as hurricanes and volcanoes may have played a part, as well as over-harvesting for food, with an estimated annual take of 8,000-36,000 (the government imposed a hunting ban on this former national dish, when populations started to decline).

Adding to the dilemma of this critically endangered amphibian is the world wide chytrid fungus crisis, a disease that is decimating frog populations around the globe. Although the island of Dominica has been infected since 2002, the island of Montserrat managed to remain disease free--until recently. In late 2008 or early 2009 the fungus made the jump to Montserrat and is currently decimating the Giant Ditch Frog population there, killing hundreds in just the past few weeks.

Fortunately, Durrell Wildlife Conservation Trust and the Zoological Society of London (ZSL) have stepped in to help save this rare animal. Going into an area of healthy frogs where the disease had not yet reached, conservationists have successfully removed 50 individuals and airlifted them to Europe for use in a captive breeding program. Twelve of the Frogs will go to the ZSL, 12 to Durrell Wildlife, and the remaining 26 will go to Parken Zoo in Stockholm. The frogs will be kept in special biosecure housings to prevent infection by the chytrid fungus.

The goal is to breed the frogs and reintroduce individuals to disease-free areas of Montserrat within two years. Although the frogs have been bred in captivity before, it is a difficult process, as they have huge appetites and have unusual breeding habits for frogs. After digging a hole in the ground and filling it with foam, the female deposits 15-50 tiny eggs. The eggs hatch and develop into tadpoles, all in this isolated foam nest. For food, the mother deposits unfertilized eggs every few days for the young to feed on.

Although the captive breeding program promises hope for the Giant Ditch Frog, more needs to be done. Durrell Wildlife is currently raising funds to build an additional bio-secure facility to house these endangered frogs. For as little as 10 pounds (15 USD, 18 CAD), you can support the care of a Giant Ditch Frog. Donate or shop online or call Natalie Ranise on 01534 860013 (UK).

Purple, but Ugly

Purple Frog (Nasikabatrachus sahyadrensis), Endangered

The first ever video footage of the Purple Frog is now available, thanks to EDGE (Evolutionarily Distinct and Globally Endangered).

Those who know me well, know that my favourite colour is purple. But the colour of this frog isn't enough to make me call it beautiful. Or even anything short of hideously ugly. This is one creature that truly deserves its place over at Endangered Ugly Things. The BBC recently said that it "looks more like a squat, grumpy blob than a living creature.”

It was discovered in 2003. It spends most of it's time underground, where it eats termites, and only comes to the surface for a few weeks during the monsoon season, to breed. It belongs to the first new frog family to be discovered since 1926, is thought to belong to an ancient lineage of frogs, placing it at #4 on the list of EDGE Amphibians.

Total population is unknown, though it's thought to be rare, as only 135 individuals have ever been observed. Confined to a few small pockets in India, its minimal habitat is threatened, as forests are cleared to make way for plantations of cardamom, coffee, ginger, and other spices.

You can help by learning more about the Purple Frog, or supporting EDGE in its mission of protecting unique and endangered species.

Little Rhinos Offer a Little Hope

Javan Rhinoceros (Rhinoceros sondaicus), Critically Endangered

The Javan Rhinoceros is believed to be the rarest large mammal in the world. With only 40-60 individuals still alive, scientists worry whether the population was large enough to recover. It once lived in Bangladesh, Myanmar, Thailand, Cambodia and Lao PDR. Today, it survives in two tiny isolated parks in Viet Nam and Indonesia. To really get an idea of its current and historic range, check out this excellent map from Wikipedia. Ujung Kulon National Park, on the western tip of Java has an estimated 50 individuals. Cat Tien National Park in Viet Nam has a mere 6 to 8, which may no longer be a viable population.

Some good news for these giants--scientists recently observed four young rhino calves and their parents in Ujung Kulon. According to the head of the park, the young rhinos were between 6 and 7 months and were in the company of their parents. This is a ray of light for the declining species and offers hope that they may be able to breed quickly enough to recover. Still they face difficult times, with the largest threat coming from poaching for traditional Chinese medicine. There are no Javan Rhinos in captivity to provide captive breeding or insurance populations.

Abundant or Rare?

Pgymy Tarsier (Tarsius pumilus), Data Deficient

The Pygmy Tarsier, thought by some to be extinct, has been rediscovered. This giant-eyed, four inch long primate lives on the island of Sulawesi in Indonesia, and was previously known only from a few specimens collected for a museum in 1921. In 2000, scientists accidentally trapped and killed one, while studying rats.

Determined to learn more about these creatures, Sharon Gursky-Doyen set out to find them. With the help of her graduate student Nanda Grow, a team of locals, and a large number of mist-nets (very fine netting for catching small animals and birds), two males and one female were captured and fitted with radio collars.

So far, there are more questions than answers. Why do Pygmy Tarsiers have claws instead of nails, as most primates do? Why don't they call to each other or mark their territory with scent? (Gursky-Doyen thinks they may be vocalizing at frequencies out of the range of human hearing). How many Pygmy Tarsiers are still out there and where exactly do they live?

This is perhaps the most important question. Listed as Data Deficient by the IUCN, Pygmy Tarsiers may be on the brink of extinction. With fragmented habitat and humans encroaching on their space, they might be extinguished like a match in the wind. Or, they might be numerous and widespread, and simply very hard to observe, since they live in the high mountains and only come out at night.

Gursky-Doyen and Grow are working on a paper that will hopefully answer some of these questions. They hope that whatever happens, the rediscovery of this species will encourage government officials to offer it some protection. Although part of its range is within the 2000 square kilometers of Lore Lindu National Park, it shares that space with 60 villages, some of which are expanding into the mountains.

If you want to help the Pygmy Tarsier, you can donate to the Nature Conservancy, which is working to protect Lore Lindu National Park. Make sure to direct your donation to Indonesia.

More for Your Money

Normally, here at Not Extinct Yet, I tend to focus on organizations that are working on conservation of endangered species or animal groups--the Kakapo, the Vaquita, Rhinos, Frogs, etc.

But for Earth Day 2008, I thought I'd present an opportunity to give, which will help conserve an endangered ecosystem--the Atlantic Forest of eastern Brazil. The forest, a hot-spot of biodiversity, has lost 93% of it's original area. It is home to many endangered species, including the Golden Lion Tamarin.

The Nature Conservancy, one of my favourite organizations, has started the Plant a Billion Trees campaign, to restore the Atlantic Forest. Their goal is to, well, plant a billion trees obviously. Over the next seven years, they will plant Guapuruvu, Golden Trumpet, Ice-cream Bean, and Capororoca trees, which will restore important habitat, as well as remove CO2 from the atmosphere.

For just $1, you can plant a tree. Every tree counts!

Happy Earth Day!
