1. Wildlife adapting and thriving in the Chernobyl Exclusion Zone
“It is 40 years since the Chernobyl disaster that led to the creation of the Chernobyl Exclusion Zone (CEZ). Since 1986, it has turned into a thriving, unintentional wildlife sanctuary and a vast rewilding “laboratory.” The CEZ prohibits people living there, commercial activities, natural resource extraction, and public access. Now the area is home to flourishing populations of large mammals.”
Read the full article to learn more about the return of endangered species as well as the how they have adapted to better cope with the environmental conditions.
'It is now one of Europe’s largest nature reserves, providing an important site for ecological research, particularly for how ecosystems recover when undisturbed.' #rewilding #conservationoptimismhttps://t.co/0EQkt1N2eD

2. Mexican gray wolf crosses border from US into Mexico
“For the first time in decades, a radio-collared wolf last week relocated from the United States into Mexico. The wolf, dubbed “Cedar,” crossed through the last stretch of southern New Mexico without a border wall in the remote Bootheel region. U.S. Customs and Border Protection has begun extending the wall where Cedar crossed, which would block wildlife in the future.
“It is so exciting to know that Cedar was able to find his way south into Mexico in search of the things he needs to thrive,” said Cyndi Tuell, the Arizona and New Mexico director at Western Watersheds Project. “His adventures highlight the need to maintain connectivity between the United States and Mexican populations of lobos and the need for all of us to push back on the devastating plans of the current administration to cut the North American continent in half with more border walls and barriers.””
🚨Exciting news for Mexican gray wolves! For the first time in decades, a radio-collared wolf has dispersed from the United States into Mexico. The wolf, named "Cedar", is an adult male who recently traveled through the last unfenced stretch of southern New Mexico. Read more: https://bit.ly/4nmIkhz

3. Angola’s highest mountain and its unique wildlife are now protected
“Angola has declared its highest mountain, Mount Moco, part of a new conservation area to protect its threatened Afromontane forests.
The Serra do Moco Conservation Area, which includes a complex of elevations, slopes and valleys in the municipality of Londuimbali, Huambo province, will now be under “a special regime of environmental protection, biodiversity conservation, and sustainable use,” according to a government notice published April 9.
“We can now engage formally with the local communities and government authorities about the core designated environmental conservation area and how we’re going to compensate [villagers] for giving up certain activities,” Vladimir Russo, executive director of Angolan conservation NGO Kissama Foundation, told Mongabay.”
“The news that the government of Angola has now moved to give the mountain formal protected area status is a moment for real celebration and congratulations” #rewilding #conservationoptimismhttps://t.co/nzjEW8js5Q

4. In Nepal’s plains, traditional bins help keep food safe from heat, floods
“In Nepal’s southern plains, Indigenous communities such as the Tharu and Yadav use traditional earthen storage bins (dehari) to safely store grains and seeds, relying on knowledge passed down through generations. Made from locally available materials such as clay, husk and dung, the bins naturally regulate temperature and moisture, helping protect crops from extreme heat, pests and seasonal flooding without electricity.
“Experts say these traditional storage systems are climate-adaptive, environmentally friendly and crucial for preserving local seed diversity and sustaining smallholder farming systems.”
Indigenous storage systems in Nepal offer a blueprint for climate adaptation. Made of clay and husk, traditional dehari bins naturally regulate temperature to keep seeds safe and are key to sustaining smallholder farms in a changing climate. @tankadhakal.bsky.social reports for #Mongabay.

5. Ghana establishes its very first marine protected area
“Last month, Ghana made news when it declared its first marine reserve and sited it in one of the nation’s most ecologically and biologically significant marine environments.
“Ghana’s minister for fisheries and aquaculture explains in a new commentary that the Greater Cape Three Points reserve will help restore marine ecosystems and protect the livelihoods of 21 coastal communities, while advancing the nation’s 30×30 conservation goal ahead of next month’s Our Ocean Conference in Kenya.
““We urge governments everywhere to follow in Ghana’s footsteps to protect more of our ocean, invest in effective management, and ensure communities are at the heart of these efforts,” the minister writes.”
Last month, Ghana declared its first marine protected area: Greater Cape Three Points Marine Protected Area!

This has the potential to not only restore marine ecosystems but also help rebuild Ghana’s fisheries for future generations. @emeliaarthur_ https://t.co/ZVCElO2GqO
6. Australia establishes the Great Koala National Park to link habitats and protect the iconic species
“The government of New South Wales has created a vast new protected area, the Great Koala National Park, along Australia’s east coast to safeguard koalas and 66 other threatened native species. Conservationists say this could mark a turning point for a species that is declining rapidly as the eucalyptus forests they depend on disappear and climate change sparks more frequent, intense wildfires.
“However, loopholes in land-use regulations, ongoing logging, development pressures and weak enforcement still threaten this key koala habitat. Experts warn that without stronger safeguards and consistent policies, the protected area may not be able to foster lasting conservation gains for koalas and other species.”
Australia has created the Great Koala National Park to protect the iconic species and 66 others. While conservationists call the move a turning point, they warn that logging and land-use loopholes could undermine the park’s ability to foster lasting gains for threatened wildlife.

7. World Migratory Bird Day: Meet the people preserving the scientific practice of bird banding
In celebration of World Migratory Bird Day (May 9), learn how crucial data is collected on migratory birds and meet the people on the ground who help gather that data, one bird at a time.
Head on to The Narwhal for the full feature on bird banding, including the amazing volunteers who make annual banding efforts possible, and how politics is threatening international data collection that drives conservation efforts.
Birds connect the world, crossing borders as they migrate across the globe, and uniting an international community of birders. Our 2025 BIPOC Photojournalism Fellow, Paula Razuri, got to know bird banders in Ontario, whose efforts rely on international cooperation: thenarwhal.ca/bird-banding...
