New York City is the most densely populated city in the U.S., but along Broadway, a thoroughfare on the northern half of Manhattan’s west side, a series of small parks, known as malls, are providing a green corridor of trees, shrubs and flowers for birds and insects.

The Broadway Malls are a series of small parks each measuring roughly 73 by 6 meters (240 by 20 feet). They serve as a median in the middle of the road and together comprise more than 4 hectares (10 acres) of green space, running 8 kilometers (5 miles) long.

The malls were established in the 1850s, around the same time as Central Park.

“The idea was to imitate the boulevards of Europe, namely France, create that grandiosity of a very wide avenue with a pedestrian path in the middle,” Ian Olson, director of horticulture with the nonprofit Broadway Mall Association (BMA), told Mongabay in a video call.

By the 1960s, the malls were neglected “tubs of dirt,” Olson said. In the ’80s, the BMA began to revitalize the spaces, largely with nonnative plants like English ivy. “Things that look nice on a median but don’t have a lot of ecological value,” Olson said.

Now, Olson and his team are removing the nonnative species and replacing them with native plants including golden rod, columbine, aster and sedge.

They’ve so far given the native plant facelift to six of the 83 malls and they’re seeing results. Jay Holmes, a naturalist with the American Museum of Natural History, created an iNaturalist project for the mall between 150th and 151st streets. So far, citizen scientists have recorded more than 100 species of plants and animals there, including several species of bees, moths and butterflies.

Holmes told Mongabay by email that he observed a parasitic bee that lays its eggs in the nests of other bees. “You might consider that a problem, but I was super excited, it is an ecosystem! To have predators, you need to have prey. The plants attracted the plant dependent insects, and the predators were coming in!”

Birds are also making use of the string of parks. New York City is on the Atlantic Flyway and a crucial stopover for roughly 25 million migrating birds annually. The tiny pockets of green space with trees for rest and insects to eat “may help fill critical habitat gaps, offering refuge for migratory birds passing through the city,” Dustin Partridge, director of conservation and science with the nonprofit NYC Bird Alliance, told Mongabay in an email.

Bird Alliance surveys have documented 17 species using the malls, including Baltimore orioles (Icterus galbula) and blackpoll warblers (Setophaga striata).

“If birds are finding these habitats useful, as our early data suggests, we hope our findings will help support further restoration of the Malls and inspire similar efforts in New York City and beyond,” Partridge said.

In November 2023, Mongabay reported on an expedition in which researchers partnered with Indigenous communities and government agencies in Indonesia’s Cyclops Mountains to capture camera-trap images of what was previously thought to be a “lost” species: Attenborough’s long-beaked echidna, the world’s rarest egg-laying mammal. Those findings have now been confirmed in a new study.

Listed as critically endangered on the IUCN Red List, Attenborough’s long-beaked echidna (Zaglossus attenboroughi) is one of five species that are monotremes, the only group of living mammals that lay eggs instead of giving birth to live young.

The echidna was first described as a new species in 1998 using a specimen collected in 1961 on the Cyclops Mountains, along Indonesia’s border with Papua New Guinea on the island of New Guinea, where the Yongsu Sapari and Yongsu Dosoyo communities live. The echidna was named in honor of famed naturalist David Attenborough; the communities call it payangko.

Since 1961, the echidna remained scientifically undocumented for 62 years, until researchers in 2007 found indirect traces of it in the Cyclops Mountains. Meanwhile, Indigenous communities in the region reported seeing the elusive species through the decades.

Relying on this Indigenous knowledge, a team of researchers deployed camera traps in the Cyclops from 2022-2023: the team received the Indigenous groups’ blessing to enter sacred areas and guidance on where to place camera traps and find the species.

“We would not have succeeded without their support and input,” Malcolm Kobak, study co-author from local NGO YAPPENDA, told Mongabay by email.

By 2023, the cameras had captured 110 photos and 15 videos that researchers confirmed were of Attenborough’s long-beaked echidna. Some footage even showed one individual following closely on the heels of another, suggesting courtship.

Co-author James Kempton, from the University of Oxford, U.K., told Mongabay by email that this was “encouraging evidence that the population is breeding.”

Today, Z. attenboroughi likely only exists in the Cyclops, but subfossil evidence suggest it used to occur on another mountain range, the team found.

“It is also important to note that the population used to exist in the Oenake Mountains in Papua New Guinea but appears to have been hunted to extinction,” Kempton said. “Its persistence in the Cyclops Mountains might reflect something to do with more sustainable Indigenous hunting and land management practices in the Cyclops, especially on the northern slopes.”

The researchers write that this underscores the need to recognize Indigenous and local knowledge “not as an ancillary resource but as a fundamental and complex backdrop to developing a conservation strategy for Z. attenboroughi and the Cyclops Mountains.”

Both Kempton and Kobak said there’s limited financing, conservation and biodiversity research in the Indonesian half of New Guinea, and that they hope the study will help attract support for additional research. Study lead Gison Morib of YAPPENDA is continuing research in the field to better understand the species.

Residents of Mafia Island in Tanzania don’t really eat sea cucumber; they call it jongoo bahari, or “ocean millipede” in Swahili. But sea cucumbers are a prized delicacy in East Asia, where demand has fueled a black market for the spiny sea creatures, Mongabay’s Ashoka Mukpo reported in May.

A kilogram of dried sea cucumbers can fetch hundreds of dollars, which is why in many coastal areas, including in Tanzania, poaching has forced them to the brink of extinction, Mukpo wrote.

Mafia Island is a tourism destination for diving and snorkeling, well-known for whale shark tours.  However, it also suffers from overfishing, which is driving fishers farther out to sea to catch enough fish. The island’s sea cucumber population collapsed in the 1990s following the arrival of Chinese traders in the 1970s and a booming trade in echinoderms, the group that includes sea cucumbers, starfish and sea urchins.

The decline in the sea cucumber population prompted the government to ban exports from the Tanzanian mainland in 2003. But trade continued from Mafia, which falls under the semiautonomous government of the nearby island of Zanzibar, so middlemen bought illegally harvested sea cucumbers there, Mukpo reported.

In the late 2010s, amid increasing demand and prices, the Tanzanian government decided to regulate trade by encouraging offshore sea cucumber farming operations.

Waziri Mpogo was the first to open such an underwater sea cucumber “ranch” near Mafia Island. He said farming sea cucumbers can help increase their population and provide income for locals.

Unlike other farmers, Mpogo doesn’t enclose his sea cucumbers with a fence, allowing them to grow “free-range.” He said it’s better for them to be part of a thriving ecosystem, connected to the rest of the ocean, with sea turtles and fish freely swimming in his ranch’s seagrass meadow.

“[Sea cucumbers] can’t be domesticated like sheep or camels or hens,” Mpogo told Mukpo. “They need human protection, but if you restrict them to one place and fence it, you deprive them of important aspects of life. In some stages they need sun rays, and in others they need to be in the deep ocean.”

Among the five species on his ranch is the endangered pineapple sea cucumber (Thelenota ananas), considered one of the most valuable species in East Africa.

While Mpogo has the permit to farm and harvest the sea cucumbers, he’s waiting for final approval to export. For Mpogo, sea cucumbers are a labor of love, but he still needs a return on his investment. A kilo of the sea cucumbers can fetch $250 to $350, depending on the species.

“My dream is to make this project the best in Africa so that more researchers come here to help us improve it,” he said. “I don’t want to see the fish or sea cucumbers drying up.”

The ocean has long been treated as the world’s forgotten frontier — out of sight, out of mind, and dangerously overused. Yet efforts to reverse decades of neglect are gaining momentum. Late April saw the launch of Revive Our Ocean, a new initiative helping coastal communities create marine protected areas (MPAs) to restore marine life and local economies.

Led by Dynamic Planet with support from National Geographic’s Pristine Seas initiative, the effort comes at a pivotal moment. In 2023, countries agreed a historic treaty to safeguard ocean biodiversity. But of the 100-plus nations that signed, only 21 have ratified it, with major backers like the U.S. notably absent. With a 2030 deadline looming to protect 30% of the oceans, Revive Our Ocean’s founders argue that waiting for governments will not be enough.

“We’ve seen that marine protection works,” says Kristin Rechberger, founder of Dynamic Planet and a Mongabay board member, in an interview in April. “But progress has been far too slow. To meet 30×30, we would need over 190,000 new protected areas. That’s why we’re focusing on communities — those who know their waters best.”

Rechberger’s optimism is based on experience. Over the past decade, Dynamic Planet and Pristine Seas have helped establish 29 of the world’s largest marine reserves, covering nearly 7 million square kilometers (2.7 million square miles), mostly offshore. Now the focus is shifting closer to shore, where coastal populations depend on healthy seas for their livelihoods.

Revive Our Ocean aims to equip communities with the tools, policy support and training needed to establish local MPAs. It blends lessons from past successes with the realities of coastal life.

Marine protection near coasts faces three barriers, Rechberger explains: awareness, policy, and know-how.

In many places, local governments lack the authority to create MPAs. Even where laws permit it, communities often lack resources or incentives to act. Revive Our Ocean seeks to change that by providing practical support and advocacy, making marine reserves as common as public parks.

The economic case is strong. A small MPA can generate significant returns. Spain’s Medes Islands Marine Reserve — just 1 square kilometer (0.39 square miles) — generates 16 million euros ($17.6 million) a year in tourism revenue, far surpassing local fishing income. In parts of Mexico, dive tourism now rivals the fishing industry in value.

Conservation and economic growth are no longer seen as opposing forces. Reviving marine life can, in fact, revive entire communities.

“It’s thrilling,” Rechberger says. “Protection drives benefits across multiple sectors, while restoring ecosystems.”

Still, the clock is ticking. Only about 8% of the ocean is under some form of protection, and just 3% is fully protected.

Revive Our Ocean’s bet: by empowering communities and sharing success stories, marine conservation can catch fire from the ground up.

BRASILANDIA, Brazil (AP) — Brazil has auctioned off several land and offshore potential oil sites near the Amazon River, aiming to expand production in untapped regions despite protests from environmental and Indigenous groups. The protesters outside the venue on Tuesday warned of potential risks that oil drilling poses to sensitive ecosystems and Indigenous communities in the Amazon. A luxury Rio de Janeiro hotel hosted the auction conducted by the National Oil Agency. Most of the 172 oil blocks for sale are in areas with no current production, such as 47 offshore locations close to the mouth of the Amazon River and two sites inland. At least 19 offshore blocks were awarded to Chevron, ExxonMobil, Petrobras and CNPC.

Oil-soaked pelicans struggling to fly came to symbolize the catastrophic impacts of the 2010 BP Deepwater Horizon oil spill on the inhabitants of the Gulf of Mexico. Fifteen years later, brown pelicans in the region have seen some recovery, but other wildlife species haven’t been as fortunate, Mongabay’s Liz Kimbrough reported in April.

Researchers estimate that some 1 million birds, across 93 species, were killed due to the disaster, when an oil rig operated by BP Exploration & Production exploded and sank off the Louisiana coast, becoming the largest offshore oil spill in U.S. history.

Of the dead birds, there were an estimated 27,000 brown pelicans (Pelecanus occidentalis). Oil from the spill had destroyed much of the bird’s critical nesting habitat, but the species, which was among the hardest hit, benefited from the rebuilding of islands for nesting, paid for with settlement money from BP.

Around $18.7 million was spent on a project expanding Queen Bess Island off Louisiana to create 15 hectares (37 acres) of habitat for pelicans and other birds. The results are impressive, Kimbrough writes: wildlife officials recorded 30,000 birds on the island in 2023, including 6,000 brown pelican nests.

“So I think populations, if you can give them healthy habitat, they can recover with time,” Alisha Renfro from the National Wildlife Federation told Kimbrough.

Sea turtles, meanwhile, saw huge declines due to the oil spill, with an estimated death toll of 4,900-7,600 large juvenile and adult sea turtles and 56,000-166,000 small juvenile sea turtles. Between 27,000 and 65,000 Kemp’s ridley turtles (Lepidochelys kempii) died there in 2010.

“Even today, researchers are finding evidence of lingering health impacts on some Kemp’s ridley sea turtles, such as abnormal hormone levels that can affect metabolism and other body processes,” according to the National Wildlife Federation.

Although rescue teams retrieved sea turtles and their eggs, treated and then release them in clean waters after the disaster, the critically endangered Kemp’s ridley, the vulnerable loggerhead (Caretta caretta), the endangered green (Chelonia mydas) and the critically endangered hawksbill (Eretmochelys imbricata) sea turtles are still in peril. Experts say it will likely take many more years to know the impacts of the spill on sea turtles that spend most of their lives at sea.

Whales and dolphins, too, are continuing to see long-term effects, with steep population declines and lingering health impacts. Bottlenose dolphins (Tursiops truncatus) in heavily affected Barataria Bay are still sick 15 years later, Cynthia Smith from the National Marine Mammal Foundation told Kimbrough.

Meanwhile, responders to the oil spill have experienced changes in blood, liver, lung and heart functions years after the spill. “I think 15 years is too early to tell what many of the impacts from the spill are still going to be,” Martha Collins, an environmental lawyer, told Mongabay.
