1. Greater one-horned rhinos rewilded in India’s Dudhwa National Park

At the end of March, four greater one-horned rhinos were moved a fenced rehabilitation area into Dudhwa National Park’s core grassland habitat, making it a total of 8 free-ranging rhinos in the park. Dipankar Ghose, Senior Director, Biodiversity Conservation, WWF-India, said, “Rhinos are one of the best indicators of grassland ecosystems. They are often called ecological engineers, as by continuous grazing, they prevent tall and unpalatable grasses from dominating.” A viable population of free-ranging rhinos would benefit the larger Terai Arc landscape, he said.

Independent experts say the coming months will be crucial to assess whether the released rhinos settle, establish stable home ranges and avoid straying into high-risk areas.

2. UK nature reserve helping restore common crane population

The RSPB’s Lakenheath Fen site in Suffolk has been home to common cranes since 2007, with three breeding pairs currently established at the reserve.

The species went extinct in the UK about 400 years ago due to overhunting and the loss of wetlands, but last year saw a record 37 chicks born across the country.

Dave Rogers, site manager of RSPB Lakenheath Fen, said rebuilding the population was a “slow process” and he felt honoured several birds had chosen the reserve to raise their chicks.

3. Cloud jaguar spotted in Honduras for the first time in 10 years

A rare “cloud jaguar” was photographed in Honduras’ Sierra del Merendón mountains, marking the first such sighting in the region in a decade.

“Cloud jaguars” are jaguars that live in cloud forests, a type of rainforest found high in the mountains where clouds sit low among the trees. Experts say high-elevation jaguar sightings are extremely rare and highlight both the species’ resilience and ongoing conservation efforts

4. 30-year Himalayan project shows power of community-led forest restoration

A 30-year forest restoration project in India’s Western Himalayas transformed degraded land into a biodiverse ecosystem through the participation of local communities.

According to a recently published study, the project resulted in the establishment of 88 tree species that are now naturally multiplying, and employed simple bioengineering techniques to retain soil moisture, resulting in long-term natural regeneration and ecological stability.

The restored site, named Surya-Kunj, or Sun-Grove, now supports rich biodiversity, including more than 160 bird species as well as medicinal plants. Strong community participation and educational value has helped turn the project into a scalable model for mountain ecosystem recovery, researchers say.

In Himalayas, a 30-year project has turned degraded land into a thriving ecosystem. With 88 tree species & 160 bird species, Surya-Kunj proves that community-led restoration and simple bioengineering can achieve long-term ecological stability and biodiversity.

5. Translocated female grizzly bear emerges from new den in Yellowstone with two cubs

In a press release, Montana Fish, Wildlife & Parks reported the welcoming sight of a female grizzly bear with two cubs in tow, after she had been relocated to Yellowstone National Park two years ago in a joint effort between the states of Montana and Wyoming.

FWP director Christy Clark celebrated this as a success for grizzly bears’ genetic diversity in the region, which is important for the species’ long-term survival. Cecily Costello, FWP grizzly bear researcher, also said, “[T]here had been some concern among biologists because the bear moved extensively after being relocated to her new territory. We wondered if that energy expenditure might reduce her chances of reproducing, but, from the photo, she appears to be in great condition.

Read the full press release here, and check out FWP’s video below to learn more about the impact of these two new cubs.

6. ‘Rediscovered’ species in Papua spotlight importance of Indigenous knowledge

Two species of marsupial thought by scientists to be extinct for thousands of years still live in the forests of Indonesian Papua on the island of New Guinea, according to recently published research.

One of the animals, the ring-tailed glider, is sacred to the Tambrauw people, and it’s part of a newly proposed genus, Tous, borrowing the Tambrauw name for the glider. The other animal, a pygmy long-fingered possum, was discovered during a mammal-watching trip on the Bird’s Head Peninsula.

The research involved substantial collaborations with local communities and Indigenous elders.

Two marsupials thought to be extinct for millennia have been rediscovered in Indonesian Papua. Researchers documented the pygmy long-fingered possum and the "Tous" glider. The find was made possible through deep collaboration with Indigenous elders. @john-cannon.bsky.social reports for #Mongabay.

7. From a Surrey oil well to the supreme court: how an activist changed UK climate law

Read the full article in the Guardian to learn more about activist Sarah Finch, who is being celebrated by the Goldman Environmental Prize along with 6 other female grassroots activists from around the world, in a record-first for the prestigious award.

Back in 2010, Sarah Finch learned of a proposal to use new fracking methods to drill for oil in Surrey, near her home. Over the next few years, she organized mass local protests and formed the Wealed Action Group (WAG) to oppose the plans. When the developer and Surrey council refused to back down and made moves to relax the environmental impact standards they were breaking, she brought the case to the UK Supreme court.

It was only in 2024, five years after the legal challenge began, that the court delivered the landmark ruling which would change the game for climate campaigning across the country: ” The climate impact of burning coal, oil and gas must be taken into account when deciding whether to approve projects, wherever that burning takes place.”

“Finch, meanwhile, continues campaigning. “It’s a kind of war of attrition with the fossil fuel industry,” she says. But she believes its days are numbered. “You know, renewable energy is more efficient, cheaper, cleaner, less prone to being disrupted by mad dictators.”
