Wildlife rebounding in Uganda

December 6, 2023 By EarthWise Leave a Comment

The numbers of elephants, rhinos, and other animals in Uganda’s nature preserves is steadily improving, reversing the trend of steady declines previously caused by poachers, wildlife traffickers, and conflict.

Between the 1960s and 1980s, political conflict and lawlessness in Uganda led to massive declines in some species as poaching, trafficking, and encroachment ran rampant.

Uganda’s population of over 700 northern white and eastern black rhinos was completely wiped out in the early 1980s by people hunting them for their horns. A charity brought four rhinos in 2005 to a sanctuary called the Ziwa Rhino and Wildlife Ranch and, according to the Uganda Wildlife Authority, there are now 33 in the facility.

Increased conservation efforts have allowed the population of buffalos to increase 77% to over 44,000 since 1983. The number of elephants has surged almost 300% to nearly 8,000 over that same time period. There has also been an increase in the number of mountain gorillas in dense forests.

Over the years, the Ugandan government has brought in a string of conservation policies including lengthy jail terms for violations. As a result, wildlife populations have been on a steady recovery.

It is typical to think about species in terms of how close to extinction they are, but the ultimate goal of conservation is to recover species. This means not only gaining distance from extinction but also resuming a species’ role in its ecosystem and repopulating its former range. Whether the wildlife in Uganda is achieving this status remains to be seen, but the trends are very positive.

Wild pigs in the U.S.

November 17, 2023 By EarthWise Leave a Comment

In the U.S., there are as many as nine million feral swine living in 38 states. A conservative estimate indicates that they cause about $1.5 billion in property and agricultural damage each year in this country.

Pigs were introduced to the United States centuries ago as a food source, but they quickly established wild populations. Feral domestic pigs bred with purebred Eurasian boar that were introduced for hunting, and these hybridized wild pigs spread across the landscape thanks to their prolific reproductive rates and willingness to eat just about anything.

When wild pigs forage, they upturn roots and soil with their snouts, damaging natural habitats and other animals. A 2021 study found that wild pigs are releasing over five million tons of carbon dioxide annually by uprooting carbon trapped in soil.

As a result, many programs were implemented nationwide to try to reduce populations, usually through lethal methods.

According to new research from the University of Georgia’s Savannah River Ecology Laboratory and Warnell School of Forestry and Natural Resources, recent conservation efforts have proven effective at controlling wild pig populations in the Southeastern U.S. Within 24 months of the start of control efforts in the study area in South Carolina, the research team found a reduction of about 70% in relative abundance of pigs, and a corresponding decline in environmental rooting damage of about 99%.

Wild pigs are basically a human-caused problem, and controlling their populations will require continued cooperation and collaboration.

Finding Homes For Rhinos | Earth Wise

October 6, 2023 By EarthWise Leave a Comment

Northern White Rhinos are virtually extinct; only two female individuals survive in Kenya. Southern White Rhinos also nearly vanished early in the 20th century, mostly because of excessive hunting. A surviving group of fewer than 100 animals was identified in South Africa, and ongoing conservation efforts led to the existing population of southern white rhinos, which now numbers more than 16,000.

Among the most successful conservation efforts took place at a 30-square-mile farm, Platinum Rhino, that was set up in 2009 about 100 miles southwest of Johannesburg. The owner of the farm did a great job of maintaining genetic diversity of the herd and protecting it from poachers. Eventually, it was costing $175,000 a month just for security against illegal hunters seeking rhino horns.

Faced with unsustainable expenses, the farm put the herd of 2,000 rhinos up for auction in April with a starting price of $10 million. No bidders came forward.

Fortunately, in September, the conservation group African Parks announced that it had reached a deal to take over the herd. African Parks partners with 12 countries in Africa to manage 77,000 square miles of protected areas.

The plan is to start moving the rhinos into a series of new sites in the wild starting next year. Moving the 5,000-pound animals to new locations will be complicated and expensive, costing anywhere from $1,500 to move a single rhino by land within South Africa to $50,000 for far afield air transport. African Parks is now raising funds to relocate the animals.

The Captive Lion Problem | Earth Wise

September 25, 2023 By EarthWise Leave a Comment

In the 1990s, there was rapid growth in South Africa of the private wildlife industry. Large numbers of cattle, sheep, and goat ranchers replaced their domestic livestock with wild animals that wealthy hunters would pay lots of money to shoot. Lions were among the most prized targets for these people. Over time, hundreds of ranchers became involved in the business of breeding large numbers of the big cats in cages or small enclosures. Wealthy clients paid $25,000 to $40,000 to shoot a captive-bred lion – cheaper than the cost of a true wild lion hunt and much easier too. The animals were not afraid of humans and were easy to find.

By 2015, about 200 ranches held at least 8,000 captive-bred lions. Over 600 were trophy-hunted that year, generating about $16 million in trophy fees, mostly from Americans.

Journalists and conservationists exposed poor conditions on many lion farms and many other abuses. Over time, the South African government cracked down on the export of lion bones and other body parts for taxidermy, traditional Chinese medicine, and other uses. The days of captive lion breeding seemed numbered but shutting down the lucrative industry is not easy.

Wild lions in South Africa are not endangered. In fact, existing sanctuaries and preserves have as many lions as they can sustain. What to do with thousands of captive lions is a real problem. Some have suggested mass euthanasia, but that appalling idea has garnered very little support. The future of these animals still hangs in the balance and so far, there are really no truly desirable solutions in the offing.

Trouble For Emperor Penguins | Earth Wise

September 18, 2023 By EarthWise Leave a Comment

Emperor penguins are the tallest and heaviest of all living penguin species. The loss of sea ice in Antarctica last year has led to unprecedented breeding failure in some emperor penguin colonies.

In a study published by the British Antarctic Survey, researchers found that no chicks survived from four of the five known emperor penguin colonies in the central and eastern Bellinhausen Sea. Satellite images showed the loss of sea ice at breeding sites, well before chicks would have developed waterproof feathers.

Emperor penguins are dependent on stable sea ice that is firmly attached to the shore from April through the end of the year. Arctic sea ice reached an all-time low in December 2022 with the most extreme loss seen in the central and eastern Bellinghausen Sea where there was a 100% loss of sea ice late the year.

This year, the sea ice extent in Antarctica is still far below all previous records for this time of year. As of August, when oceans normally are freezing up, there were still areas that were ice-free.

Emperor penguin populations have not had to contend with large-scale hunting, habitat loss, overfishing, or other human-caused problems in the modern era, but climate change may be their undoing. They have previously responded to incidents of sea ice loss by moving to more stable sites in the following year. But this strategy will not be successful if the sea ice habitat is affected across entire regions of Antarctica.

Scientists are predicting that 90% of emperor penguin colonies will be quasi-extinct by the end of the century, assuming current global warming trends continue.

The State Of The Birds | Earth Wise

November 28, 2022 By EarthWise Leave a Comment

The U.S. Committee of the North American Bird Conservation Initiative has published the State of the Birds 2022, an assessment of bird populations in North America. The news is not good. The report identifies 70 Tipping Point species, which are those that have lost half or more of their breeding population since 1970 and are on track to lose another half or more in the next 50 years. According to research published in Science in 2019, the United States and Canada have lost 3 billion breeding birds since 1970, which is about a quarter of the total population.

More than half of the bird species in the United States are in decline. According to the Conservation Initiative, the tipping point species in particular require proactive conservation protections to avoid becoming endangered. Species that inhabit grasslands are declining more rapidly, while waterfowl like ducks and geese are actually increasing. That increase is most likely a result of the investments in conservation funded by the hunting industry.

Those waterfowl gains demonstrate that when there are concerted efforts to protect and promote bird populations, positve changes can happen. Some say that protecting birds is not a high priority given all the other crises in the world, but what is good for birds is also good for people. For example, planting trees and other vegetation to enhance bird habitat also helps to sequester carbon, protect coastlines from storm surges, increase groundwater recharge, and reduce urban heating effects.

The loss of 3 billion birds is a major biodiversity crisis and requires action. Bird conservation benefits wildlife, people, entire ecosystems, and our planet.

Why Do Woodpeckers Peck? | Earth Wise

October 21, 2022 By EarthWise Leave a Comment

Most of us have heard the sound of a woodpecker drumming on a nearby tree, or unfortunately, on the walls of our house where it can be very destructive. We were often told that the birds were hunting for insects inside the wood, or perhaps trying to open up a nest. But a new study at Brown University has found evidence that woodpeckers are just additional musicians in the bird orchestra who happen to be percussionists.

The researchers studied the forebrains of birds and found characteristic gene expression specializations in songbirds. Songbirds sing to communicate for various reasons – such as staking out territory or seeking mates. The study looked at birds that are not known to sing, such as the emu, penguin, flamingo, and woodpeckers. It turns out that among these, only woodpeckers had forebrains that anatomically resembled those of songbirds. The study is the first time a neural basis has been identified for the communication activities of animals other than primates.

There are over 200 species of woodpeckers around the world and each species has its own characteristic drumming speed and rhythms. Woodpecker drumming may well have evolved through a form of vocal learning, which is the way songbirds learn to make their own melodious sounds. And like the calls of songbirds, these drumming patterns change depending on what the birds want to communicate and to whom.

So, the little downy woodpecker that is poking holes in your walls is probably not hunting for insects. It is more likely to be telling another woodpecker to get out of its territory.

Return Of The Fin Whale | Earth Wise

August 15, 2022 By EarthWise Leave a Comment

The fin whale is the second largest whale species and therefore the second largest creature on Earth. They can grow to more than 80 feet in length. From 1904 to 1976, there was massive industrial whaling in the Southern Ocean surrounding Antarctica. During that period, whalers killed about 700,000 fin whales, reducing their population by 99%. The species was nearly extinct.

In 1982, the International Whaling Commission voted to ban commercial whaling. Since that time, fin whales started to make a comeback in their historical feeding grounds.

During a nine-week expedition in the waters around the Antarctic Peninsula, researchers encountered the largest gathering of fin whales ever documented. About 150 fin whales were seen diving and lunging against the water’s surface. It was a feeding frenzy triggered by large amounts of krill in the water. The actions of the whales are known as a “whale pump” that drives the krill to the surface. Not only does it provide huge amounts of food for the whales but also for other animals, including seabirds and seals.

Forty years after the commercial whaling ban, the number of fin whales has been increasing. Large groups were observed in a 2013 survey. Aerial surveys in 2018 and 2019 recorded 100 groups of fin whales, usually composed of a just a handful of individuals. They did document eight large groups of up to 150 individuals.

Not all species of whales have rebounded so successfully since the whaling ban. The rebound in fin whale population is not only good for the whales, but for the entire ecosystem in the Southern Ocean. It is a glimmer of good news in a time of great challenges for global biodiversity and for marine life in particular.

Is It Too Late To Save The Vaquita? | Earth Wise

June 6, 2022 By EarthWise Leave a Comment

The vaquita porpoise, the world’s smallest marine mammal, is on the brink of extinction. Scientists estimate that just 10 or fewer vaquitas are left despite international conservation efforts. Found only in Mexico’s Upper Gulf of California, the vaquita is the most endangered marine mammal on the planet.

According to the International Committee for the Recovery of the Vaquita, the number one threat facing vaquitas is gillnets. The porpoises get trapped in these nets and drown. Gillnets are often used illegally in the region to catch shrimp and fish, including the critically-endangered totoaba. The totoaba’s swim bladder is considered a delicacy in Asia and can fetch thousands of dollars. Despite Mexico banning both totoaba fishing and the use of gillnets in the vaquitas’ habitat, many say the bans are not always enforced.

But there is a reason to be hopeful. According to a genetic analysis led by researchers at UCLA, the critically-endangered species actually remains relatively healthy and can potentially survive if illegal fishing practices cease immediately.

In the study, which was recently published in the journal Science, the research team analyzed the genomes of 20 vaquitas between 1985 and 2017 and ran simulations to predict the species’ extinction risk over the next 50 years. The researchers concluded that if gillnet fishing ends immediately, the vaquita has a very high chance of recovery. If the practice continues, however, even moderately, the likelihood of a recovery plummets.

According to the research team, the surviving vaquitas are actively reproducing and seem healthy. But poachers’ gillnets will continue to pose an existential threat to the species until more measures are taken to protect the vaquita.

Assessing Human-Caused Wildlife Mortality | Earth Wise

May 31, 2022 By EarthWise Leave a Comment

Bycatch is the fishing industry term used to describe the deaths of non-target fish and ocean wildlife during the fishing process. Some bycatch species are thrown away because regulations prohibit them from being kept. Others are thrown out because they won’t fetch high enough prices. According to some estimates, global bycatch amounts to about 10% of the world’s total catch.

Approximately half of global bycatch is a result of trawling. Trawling is a method of commercial fishing that involves pulling or dragging a fishing net – called a trawl – through the water or across the seabed in hopes of catching fish. Commercial fishing companies favor towing trawl nets because large quantities of fish can be caught. But the method is destructive to the seafloor and leads to the indiscriminate catch of all sorts of species, including whales, dolphins, porpoises, sharks, seals, rays, turtles, and seabirds.

Researchers have developed a new method to assess the sustainable levels of human-caused wildlife mortality. When this method is applied to a trawl fishery in Australia, it shows that the dolphin capture is not sustainable. The study, led by scientists at the University of Bristol in the U.K. and United Arab Emirates University, modeled different levels of dolphin capture, including those reported in logbooks and those reported by independent observers. According to the findings, which were recently published in the journal Conservation Biology, even the lowest recorded dolphin capture rates are not sustainable.

The new approach is extremely adept at assessing human-caused mortality to wildlife, and can be applied to fisheries bycatch, hunting, lethal control measures, or even wind turbine collisions.

The Ivory-Billed Woodpecker | Earth Wise

May 24, 2022 By EarthWise Leave a Comment

The ivory-billed woodpecker was the largest woodpecker in the US. They were once relatively common, stretching from the Carolinas through the southeast and across to Texas. Their numbers started to drop sharply in the 19th century because of habitat loss and overhunting. Many were taken as valuable specimens; some were even eaten by poverty-stricken people.

The last widely accepted sighting was way back in 1944. For years, the birds were listed as critically endangered with only infrequent and entirely anecdotal reports of sightings. Last year, the U.S. Fish and Wildlife Service finally declared the species extinct.

A multiyear field study by avian researchers from multiple institutions has recently reported that the ivory-billed woodpecker may in fact still exist in a remote swampy region of Louisiana.

The three-year effort to find the woodpecker involved scientists trudging through the remote site to observe birds and take audio recordings. Unmanned trail cameras taking time-lapse photos and a drone were used to capture images. Several members of the team report that they observed the birds. Some photographic images and videos appear to show ivory bills. Based on characteristic markings visible in some of the photos, the birds do appear to be the ivory bill and not, for example, the fairly common but similar looking pileated woodpecker.

The birds are scarce, live in a tough, swampy habitat, and actively avoid getting near people. They live high in trees and are very difficult to spot, much less get clear photographs of. From all indications, however, reports of the demise of the ivory-billed woodpecker may have been premature.

A War On Wolves

March 17, 2022 By EarthWise Leave a Comment

America has a long history of persecuting wolves. In 1905 the federal government tried biological warfare, infecting wolves with mange. In 1915, Congress passed a law requiring the eradication of wolves from federal land. By 1926, all the wolves in Yellowstone National Park had been poisoned, shot, or trapped. By 1945, wolves had been essentially eliminated from the American West.

All of this was driven by the fantasy that wolves were a major menace to livestock and a threat to big game.

In the 1990s, wolves were reintroduced to Yellowstone National Park and central Idaho and the result was one of the greatest success stories in the history of wildlife management. There were multiple improvements to the greater Yellowstone ecosystem. Wolves as important predators are essential elements of healthy ecosystems in the American west.

For reasons difficult to fathom, the status of wolves has become political. Conservative lawmakers in Idaho, Montana, Wyoming, and Wisconsin have essentially declared war on wolves, radically liberalizing wolf trapping and hunting regulations. In Wyoming, it is now legal to kill wolves at any time by virtually any means, including running them over with snowmobiles and incinerating pups and nursing mothers in dens. Idaho has bounties as high as $2,000 for killing wolves.

The reasons are just as bogus as ever. Livestock predation is the big claim. In 2015, 1,904 wolves shared the Rocky Mountain West with 1.6 million cattle. Wolves killed all of 148 of them.

Evidently, wolves have become identified as a liberal cause and, as such, are now the enemy of conservative politics.

Roads And Chimpanzees | Earth Wise

November 8, 2021 By EarthWise Leave a Comment

The chimpanzee is a species of great ape native to tropical regions of Central and West Africa. Chimpanzees are highly social animals and can live to be over 50 years old. In fact, chimpanzees are our closest cousins. We share about 98% of our genes with chimpanzees.

According to the African Wildlife Federation, it’s estimated that at most only 300,000 chimpanzees remain in the wild today. They face a myriad of challenges, including habitat degradation and hunting.

According to new research from the University of Exeter in the U.K., roads have a negative impact on chimpanzee populations that can extend for several miles. In the study, which was recently published in the journal Conservation Letters, the researchers analyzed the impact of major and minor roads on wild western chimpanzee numbers in the eight African countries in which they live. They found that negative impacts extended an average of 10.7 miles from major roads, and 3.4 miles from minor roads. The researchers found that the density of chimpanzee populations dropped steadily from the edges of these areas to the lowest value alongside the roads. Only 4.3% of the chimpanzees’ range remains unaffected by roads.

While the study did not investigate why roads affect chimpanzee numbers, the research team did offer some clues. In addition to noise and roadkill, roads provide access to unexploited areas for industries that often reduce or remove chimpanzee habitats. Roads can also restrict chimpanzee movements, and provide easier access for hunters.

The researchers hope their findings will bring about more effective guidelines to mitigate the impact of roads on wildlife.

Livestock Expansion And Global Pandemics | Earth Wise

August 18, 2020 By EarthWise 1 Comment

The domestication of cows, pigs, chickens, and other animals as livestock for their meat, milk, and eggs was historically revolutionary. It boosted food security by giving people a readily-available means of feeding themselves as opposed to more traditional methods such as hunting and fishing.

But animal agriculture has plenty of drawbacks. The industrialization of animal agriculture has led to horrendous conditions. Animals are kept in huge quantities and packed together with little regard for their health and welfare. This approach to agriculture is simply designed to maximize production while minimizing costs.

With its chemical inputs and toxic outputs, intensive animal agriculture is also a major threat to the environment. In fact, it’s a major driver of habitat degradation and biodiversity loss all around the globe.

But it’s not just animals and the planet that pay a price. Humans have inherited several lethal pathogens from livestock over the years, including the influenza virus that likely jumped to humans from poultry.

According to a study recently published in Biological Conservation, there is a connection between the global increase in the emergence of infectious diseases and epidemics, the accelerated loss of biodiversity, and the expansion of livestock. In the study, the research team from the Institute of Evolution Sciences of Montpellier cross referenced databases on human and animal health, livestock expansion, and biodiversity loss between 1960-2019. The team found that the number of epidemics identified in humans increased in correlation with both biodiversity loss and livestock expansion.

In the era of COVID-19, it’s important to understand how global livestock expansion directly threatens both human health and the health of the planet.

Beavers And The Warming Arctic | Earth Wise

August 5, 2020 By EarthWise Leave a Comment

Beavers have a remarkable ability to transform landscapes. Using their sharp teeth, they fell trees and shrubs and build dams, which cause small valleys to fill with water and form new lakes. Some of these lakes measure five or ten acres in size, or even more. And beavers are very efficient builders; they often build their dams at precisely those points where can they have the greatest effect with the least effort.

Scientists studying beaver activity in the Arctic regions of Alaska have found that the changing climate is leading to a substantial increase in beaver populations and their effect on the landscape.

In 2018, researchers found that the beavers living in a 7,000 square-mile area in northwest Alaska had created 56 new lakes in just five years. Thanks to rising temperatures, more and more habitats offer the shrubs that beavers need for food and building material. In addition, the lakes, which used to freeze solid, now offer beaver-friendlier conditions. Also, beavers are not hunted as intensively as in the past.

The scientists were surprised that beavers have seized the opportunity so intensively. There is basically an exponential growth in beaver dams. This is actually a worrisome situation. Forming all these new lakes degrades ice-rich permafrost in the area. In the Kotzebue region of Alaska, the overall water area has increased by more than 8% over the past 17 years, and roughly two-thirds of that is due to beavers.

The degradation of the Arctic’s permafrost is a dangerous situation and it appears that anyone who wants to predict its future has to keep the activity of beavers in mind.

Reducing Polar Bear Attacks

April 8, 2019 By EarthWise Leave a Comment

The increasing reduction of sea ice in the Arctic is changing the behavior of polar bears. Because they are spending more time on land, they are interacting with people much more frequently, occasionally with deadly results.

A study, published in 2017, looked at 144 years’ worth of polar bear attacks on humans in the Arctic. Between 1960 and 2009, there were a reported 47 attacks by polar bears on people – between 7 and 12 per decade. Between 2010 and 2014, as sea ice reached record lows, there were 15 attacks, a record for a four-year period. Since 2000, 88% of attacks have occurred between July and December, when sea ice is at its lowest level of the year.

Last July, a young male polar bear attacked and killed a man who was berry picking with his children. A month later, a mother polar bear attacked and killed an Inuit hunter and injured two others. This was the first known fatal attack by a mother polar bear.

As a result, Inuit communities in the Nunavut region are asking for higher legal polar bear harvest quotas, arguing that bear populations have increased to a dangerous level.

These recent human fatalities have also provided an impetus for developing new non-lethal conflict-resolution tools than can be used in northern communities before more people as well as bears are killed.

There are now polar bear patrol teams tasked with driving bears away from settlements. There is a bear hotline and electric fencing around sled dog compounds.

The changing face of the Arctic is creating growing stress on the polar bear population and on the people who make their home in that region.

Japan And Whaling

January 10, 2019 By EarthWise Leave a Comment

The commercial hunting of whales nearly drove the giant mammals to extinction. By the 1960s, as hunting technologies improved and ships began to resemble floating factories, it became clear that whaling could not continue unchecked.

But despite all this, commercial whaling was never actually banned. Instead, in 1986, members of the International Whaling Committee (IWC) agreed to a whaling moratorium in order to allow whale stocks to recover. Pro-whaling nations like Japan, Iceland, and Norway expected the moratorium to be temporary until the whales stocks recovered, and a consensus on catch quotas could be established. But the temporary moratorium became a quasi-permanent ban, much to the delight of conservationists and to the dismay of whaling nations.

As a result, Japan recently announced it is leaving the international agreement and plans to resume commercial whaling. The agreement though never really stopped Japanese whaling in the first place, because it allowed the country to kill whales for scientific research. Japan has had an annual Antarctic catch quota of 333 minke whales, producing notoriously little in terms of whale science while producing lots of whale meat. As part of its withdrawal from the IWC, Japan will cease its Antarctic hunts and limit whalers to its own waters. Commercial Japanese whaling will resume in July.

Once popular in Japan, whale meat consumption has plummeted, falling 98% between 1962 and 2016. The industry employs fewer than 1,000 people and is dependent on government subsidies.

Many governments and conservationist groups condemned Japan’s withdrawal, declaring the move out of step with the international community. They argue that, rather than hunting whales, urgent action is needed to conserve marine ecosystems.
