Numbat Numbers

Numbat (Myrmecobius fasciatus), Endangered

Having just spent several months living and working in Australia, Australian species are especially interesting to me right now. Koalas, Kookaburras, and Kangaroos all crossed my path, as did Wallabies, Wattles, and Wombats. What didn't cross my path was a small creature known as a Numbat. This is likely because the Numbat is no longer common in the state of Victoria, where I spent almost all of my time.

Numbats used to live all across the southern regions of Australia. Their population was reduced to two tiny pockets in the state of Western Australia after the introduction of foxes. Since then, it has been reintroduced to a few small conservation areas, but still numbers less than a 1 000 animals in the wild.

The Numbat diet is a little bit monotonous, consisting of nothing but termites. Each individual can eat between 10 000 and 20 000 termites in a day! Unlike many other termite eating animals, however, Numbats are small, and lack claws or any other method to open up termite nests. This means that they have to forage for termites when the termites themselves are out of the nest foraging--that is, during the day--making it one of the very few marsupials active during the day. Being active during the day like this is thought to make them more susceptible to predation.

In the evening, when they aren't foraging, these rare marsupials retire to their burrows, which are very often inside of hollowed out logs. It is thought that an abundance of hollow logs to hide in may have saved the two groups of Numbats that survived in Western Australia, as they provided protected hiding places from predators.

These stripy furry animals are cute, no doubt about it. They're one of Western Australia's State Emblem's, and they've also been chosen as the icon for the Conservation Council of Western Australia. A captive breeding and reintroduction program is underway, and Numbats are bred at Perth Zoo and released each year into managed habitat. Here's a great video about hand-rearing baby Numbats at the zoo.

Yaminon

Northern Hairy Nosed Wombat (Lasiorhinus krefftii), Critically Endangered

This cute-ish animal is critically endangered. Endemic to Australia, it's range has steadily decreased, until in the early 80s, there were only 30-40 individuals in tiny Epping National Forest Park, about 800 km northwest of Brisbane. In 1982, Cattle were excluded from their habitat, and their population has risen to over 130.

In May of 2009, a number of Wombats were moved from Epping to a newly created nature reserve, just north of St. George, providing some protection for the species. The biggest threat to the species is a catastrophe such as fire, flood, drought, or disease, that could wipe out the entire population. Having two separate populations is a bit of a disaster insurance policy.

This largest of Wombat species, also sometimes referred to as the Yaminon, is now protected in both locations by predator proof fences to keep out dingos and other predators. Conservationists managing these populations engage in reproductive and behavioural research, as well as controlling invasive species of grass, controlled burns of habitat, DNA studies to estimate population (by collecting hair samples with tape), and much more.

If you want to help out this nearly extinct animal, here's some ideas:

You could of course donate to the Wombat Foundation.

Or you could buy some children's books featuring Willit the Amazing Wombat.

Most importantly and least expensively though, you could learn more about the Northern Hairy Nosed Wombat, and then tell your friends.

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).

Population Explosion, Kind Of

Irrawaddy Dolphin (Orcaella brevirostris), Vulnerable

In early April, the Wildlife Conservation Society announced that a population of close to 6000 Irawaddy Dolphins has been discovered in Bangladesh. Before the discovery of the populations in Bangladesh, only a few small pockets of dolphins were known, most numbering less than 150. In short, the dolphins from Bangladesh have increased the known population more than six times.

Brian Smith, who led the study, expressed optimism for the future of the Irrawaddy Dolphin, but cautioned that the many threats still exist, including entanglement in fishing nets, declining freshwater supplies, and climate change.

The Wildlife Conservation Society is working with Bangladeshi officials to create a sanctuary for the dolphins in the mangrove forests where they live.

Keep your fingers crossed if you want to help the Irrawaddy Dolphin. Or you can take action and send an email to your Congressperson (if you live in the US), or support the WCS in their mission of Saving Wildlife.

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.

Eggs, Eggs, Eggs

Kakapo (Strigops habroptila), Critically Endangered

According to Radio New Zealand, this year could be a lucky one. With a population of less than 100, the critically endangered Kakapo has been slowly increasing due to dedicated conservation efforts. This breeding season, the Kakapo Recovery Programme is hoping for forty chicks.

Previously on this blog, the importance of rimu fruit to Kakapo breeding was discussed, and it appears that a bumper crop may be in the works. Additionally, there are more fertile adult females, than there have been in years. If these factors come together, the Kakapo population could increase by nearly 50 percent. With so many chicks, some would be raised by their parents, instead of hand-reared by humans, as they sometimes are when chicks are rare.

The breeding season has started less than a month ago, with the first mating of the season occurring on Christmas night. Chicks are expected in late February.

Keep up to date by following the Kakapo Ranger Diaries.

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.

David vs. Goliath, Mice vs. Albatross

Tristan Albatross (Diomedea dabbenena), Critically Endangered

According to Scientists from The Royal Society for the Protection of Birds (RSPB), the Critically Endangered Tristan Albatross has suffered its worst ever breeding season. Out of 1764 chicks counted in January, only 246 survived to fledge.

Tristan Albatrosses, which breed only on British-owned Gough Island in the South Atlantic, are being decimate by mice. According to Richard Cuthbert, an RSPB scientist, mice have been known to prey on the birds for a long time. Previously, the birds were threatened by introduced and non-native rats, pigs, dogs, and cats. Once these predators were removed, the mice population expanded.

The mice, originally introduced in the 18th or 19th century by sealers, are now three times larger than their mainland brethren, and have adapted to be carnivorous--subsisting on young birds and eggs rather than seeds and insects. Even though the mice have become larger, they are still vastly outweighed by the albatross chicks. Why don't the albatrosses fight back? Although they do fight back against other types of prey, it seems that they are not able or do not know how to appropriately fend off the non-native mice. The mice often work together, attacking at night, quickly gnawing through the nest and straight into the chicks body.

With such low numbers of surviving chicks, Tristan Albatrosses are very close to the brink of extinction. Relatively slow breeders, pairs only nest every other year, producing a single chick each time. Adults are further threatened by the long-line fishery. Fishing boats towing miles of fishing line, with thousands of hooks baited with squid or fish, often attract Albatrosses, who attempt to snag the bait and become entangled or hooked and drown.

"Tristan Albatross is being hit by a double whammy. The chicks are predated by mice and the adults and juveniles are being killed by longline fishing vessels," said John Croxall, chair of BirdLife's Global Seabird Programme. "Unsustainable numbers are being killed on land and at sea. Without major conservation efforts, the Tristan Albatross will become extinct."

Is there any hope? Some. In New Zealand, similar situations with rats have been successfully dealt with by dropping rat poison from helicopters. The RSPB has done preliminary studies indicating that a similar solution would solve the mice problem on Gough Island, and is encouraging the British government to come up with the needed funds.

Baby Goliaths Can't Hide

Goliath Grouper (Epinephelus itajara), Critically Endangered

The Critically Endangered Goliath Grouper is the largest grouper in the Atlantic, growing more than 2 meters (6 feet) long, weighing more than 450 kg (1000 lbs), and living up to 40 years. Recently, the Ocean Research & Conservation Association (ORCA) used an underwater acoustic camera system (similar to the sonar dolphins or bats use) to visualize baby Goliaths among the murky waters of mangrove roots. Baby Goliaths, up to 1 meter long, spend the first 5-6 years of their lives, almost exclusively in and amongst the waters around mangroves.

Conservation action began in 1990 when the US placed a moratorium on fishing, and the Caribbean did the same in 1993. Though the population has increased it will take many years for numbers to recover to previous levels. Additionally, in some areas, fishing continues despite the bans. It is sometimes difficult to accurately assess the recovery of the species, in part because of the inability to visualize Baby Goliath numbers in murky and cloudy waters. The new camera system used by ORCA should alleviate this problem, and make surveys of Goliath populations easier.

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.

First Home for Blue-throated Macaws

Blue-throated Macaw (Ara glaucogularis), Critically Endangered

With only an estimated 300 individuals surviving in the wild, the Blue-throated Macaw is critically endangered. The threats come mainly from habitat loss and illegal trapping. To nest, the birds require motucu palms, which grow in islands dotting the grasslands of Bolivia. Unfortunately, the only known habitat suitable for the birds exists on private ranch lands, where annual burning and intensive cattle grazing occur. The other major threat to these birds is illegal trapping for the caged-bird market.

Fortunately, several conservation organizations working together have purchased an 8500+ acre ranch where Blue-throated Macaws are known to nest. This is the first protected area for these rare birds, which is great news. However, much more area needs to be protected to ensure the recovery and continued well-being of these magnificent birds. There are four other ranches for sale, that combined with the new purchase, hold 41% of the Blue-throated Macaw population. Unfortunately, at $30 an acre, the land is being eyed by foreign cattle ranchers.

If you want to help protect the habitat of the Blue-throated Macaw, you can donate to the World Land Trust, Bird Endowment, Loro Parque Foundation, or Asociación Armonía, all organizations involved in the conservation of the Macaws.

You can also buy a stuffed toy Blue-throated Macaw or sign up for a Parrot Lover's Cruise from Bird Endowment.

Wetar Ground Dove (Gallicolumba hoedtii), Endangered

The Wetar Ground Dove, a bird known from only a few specimens since the early 1900s, all of them outside its native island of Wetar. Now, it has been rediscovered on the island for which it was named, and in larger numbers than ever observed. Thirty to forty of the birds were seen together, the largest recorded congregation.

Wetar is a large island, and perhaps, according to scientists working on the island, "the single most pristine in South-East Asia". Unfortunately, the island is already facing significant pressure from development, as plans to extend an existing asphalt road will open up the interior of the steeply hilled island.

You can support Columbidae Conservation, who are working to protect the Wetar Island, for the Wetar Ground Dove and the other unique species and ecosystems that currently thrive there.

Some Birds May Smell Sexier

Kakapo (Strigops habroptila), Critically Endangered

The Kakapo, featured here several times, might benefit from a little cologne it appears. Scientists working with the Kakapo breeding program, noticed that a few of the males received significantly more attention than others, and they think it may have to do with the birds' body odor. To find out, they're sending feathers to Tom Goodwin, an animal olfactory chemist in Arkansas.

Because the Kakapo's population dropped to a gene-pool-reducing 91 individuals, genetic diversity is very important to their survival. If most of the females are only breeding with a few males, the gene-pool could remain dangerously small. If a synthetic perfume that makes less attractive males seem sexier can be developed, their genes would also get remixed into the overall population, increasing the diversity of the gene-pool.

If you want to help save the Kakapo, you can donate, become more informed, or get hands on and volunteer with the Kakapo Recovery Programme.

Hector's Dolphins Still Unprotected

Hector's Dolphin (Cephalorhynchus hectori), Endangered

A new study by researchers at New Zealand's Otago University has added to the mountain of evidence that Hector's Dolphins are being killed at a rate that will lead to their extinction . . . unless something changes. These dolphins, with their uniquely rounded dorsal fins, are declining due to commercial and recreational fishing using gill nets and other methods that entangle them as bycatch.

Hector's Dolphins have the most limited range of any cetacean, except the Vaquita. Living only around the coast of New Zealand's two islands, they are divided into two subspecies. The South Island Hector's Dolphins have been reduced to less than 7500 individuals, while the Critically Endangered North Island subspecies, also known as Maui's Dolphins, have been reduced to a mere 110 individuals.

The New Zealand government has restricted fishing in parts of the Dolphin's range, but complete protection has not been realized, partially because of resistance from the fishing industry.

If you want to help, you can petition the New Zealand Government to enact full protection, adopt a Hector's Dolphin through WWF New Zealand, or join a Facebook Cause dedicated to the Hector's and Maui's Dolphins.

Booroolong Frog (Litoria booroolongensis), Critically Endangered

Over a year ago, I wrote of the Booroolong Frog, a critically endangered species, confined to less than 10 square kilometers, and decimated by drought and forest fires.

Now, the species will receive a boost of 500 captive bred frogs, who are primed to breed. The 9 month old frogs are the offspring of 6 adults and 20 tadpoles that were taken into captivity two years ago. According to scientists involved with raising them, the males will mate in a brief breeding frenzy and die.

The species has declined because of habitat degradation and the chytrid fungus, which has affected amphibian species around the globe.

More Monkeys Is Good News

Gray Snub-nosed Monkey (Rhinopithecus brelichi), Endangered

This endangered monkey is confined to a 400 square kilometer reserve in China. Up until 1978, their mountainous home was severely disturbed and damaged due to mining activities. Since then, the Fanjing Mountains Natural Reserve has been established, and their population has increased from an estimated 400 in 1979 to 850 today.

Since 1992 the Fanjingshan National Nature Reserve Administration Bureau has successfully bred seven captured individuals, producing a mere 16 offspring-an average of one per year.

No More Protein!

Kakapo (Strigops habroptila), Critically Endangered

The Kakapo is a large ground-dwelling parrot, found only on two small, isolate islands in New Zealand. The total number of birds has risen to 91 in the past year, but this number is still precariously low.

Part of the problem is that Kakapo only lay eggs every three to five years, when Rimu Trees produce an especially large harvest of fruit. When this happens, the Kakapo feast and breed. Scientists have been trying to increase the frequency with which these beautiful birds breed, by supplementing their diets with protein, known to be an important nutrient for other breeding species.

Now, the importance of protein for the Kakapo is being questioned. Professor David Raubenheimer has recently analyzed the nutrient content of the Rimu fruit, and found that it is low in protein and high in calcium. He thinks that calcium may be more important for breeding Kakapo, as it would be used in their eggshells and incorporated into their unusually large skeletons.

Scientists will continue to try and increase the breeding frequency of the Kakapo to boost the population, by using a new formulation of feed that more closely matches the content of the Rimu fruit. One question still remains, however. Is it just the nutrients that are limiting the Kakapo, or are they programmed to breed only when there is an abundance of Rimu fruit?

If you want to help save the Kakapo, you can donate or just become more informed.

One. Five. Zero.

Vaquita (Phocoena sinus), Critically Endangered














One. Five. Zero.

That's the estimated number of Vaquitas Marinas, or little sea cows still alive. These miniature porpoises (featured here previously), which live only in the Gulf of California, are the most endangered cetacean. If nothing is done, they are likely to become extinct within the next year or two, or sooner.

The main cause of their decline, is not habitat loss, climate change, or pollution (although these things do affect the Vaquita). The biggest threat to the survival of the Vaquita is the nets local fishermen. The nets are intended for other fish and shrimp, but an estimated 40 are caught accidentally each year. When your total population is 150, losing 40 is a big deal.

The Mexican government is pledging 16 million US dollars to pay fishermen to avoid the Vaquita's habitat or to stop fishing altogether. Some of the money will also be spent to teach fishermen alternative techniques using snares that are too small to endanger Vaquitas.

So far, about 1000 fishermen (40%) have agreed to stay out of Vaquita habitat or stop fishing altogether. This is a good start, but more is needed. With the population already so low, if the Vaquita is to make a full recovery, accidental deaths due to fishing must be reduced to zero.

Here's a great site with information about the history of the conservation of the Vaquita and the threats it faces.

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!
