"In an unprecedented transformation of China’s arid landscapes, large-scale solar installations are turning barren deserts into unexpected havens of biodiversity, according to groundbreaking research from the Chinese Academy of Sciences. The study reveals that solar farms are not only generating clean energy but also catalyzing remarkable ecological restoration in some of the country’s most inhospitable regions.

The research, examining 40 photovoltaic (PV) plants across northern China’s deserts, found that vegetation cover increased by up to 74% in areas with solar installations, even in locations using only natural restoration measures. This unexpected environmental dividend comes as China cements its position as the global leader in solar energy, having added 106 gigawatts of new installations in 2022 alone.

“Artificial ecological measures in the PV plants can reduce environmental damage and promote the condition of fragile desert ecosystems,” says Dr. Benli Liu, lead researcher from the Chinese Academy of Sciences. “This yields both ecological and economic benefits.”

The economic implications are substantial. “We’re witnessing a paradigm shift in how we view desert solar installations,” says Professor Zhang Wei, environmental economist at Beijing Normal University. “Our cost-benefit analysis shows that while initial ecological construction costs average $1.5 million per square kilometer, the long-term environmental benefits outweigh these investments by a factor of six within just a decade.” ...

“Soil organic carbon content increased by 37.2% in areas under solar panels, and nitrogen levels rose by 24.8%,” reports Dr. Sarah Chen, soil scientist involved in the project. “These improvements are crucial indicators of ecosystem health and sustainability.”

...Climate data from the study sites reveals significant microclimate modifications:

Average wind speeds reduced by 41.3% under panel arrays

Soil moisture retention increased by 32.7%

Ground surface temperature fluctuations decreased by 85%

Dust storm frequency reduced by 52% in solar farm areas...

The scale of China’s desert solar initiative is staggering. As of 2023, the country has installed over 350 gigawatts of solar capacity, with 30% located in desert regions. These installations cover approximately 6,000 square kilometers of desert terrain, an area larger than Delaware.

“The most surprising finding,” notes Dr. Wang Liu of the Desert Research Institute, “is the exponential increase in insect and bird species. We’ve documented a 312% increase in arthropod diversity and identified 27 new bird species nesting within the solar farms between 2020 and 2023.”

Dr. Yimeng Wang, the study’s lead author, emphasizes the broader implications: “This study provides evidence for evaluating the ecological benefit and planning of large-scale PV farms in deserts.”

The solar installations’ positive impact stems from several factors. The panels act as windbreaks, reducing erosion and creating microhabitats with lower evaporation rates. Perhaps most surprisingly, the routine maintenance of these facilities plays a crucial role in the ecosystem’s revival.

“The periodic cleaning of solar panels, occurring 7-8 times annually, creates consistent water drip lines beneath the panels,” explains Wang. “This inadvertent irrigation system promotes vegetation growth and the development of biological soil crusts, essential for soil stability.” ...

Recent economic analysis reveals broader benefits:

Job creation: 4.7 local jobs per megawatt of installed capacity

Tourism potential: 12 desert solar sites now offer educational tours

Agricultural integration: 23% of sites successfully pilot desert agriculture beneath panels

Carbon reduction: 1.2 million tons CO2 equivalent avoided per gigawatt annually

Dr. Maya Patel, visiting researcher from the International Renewable Energy Agency, emphasizes the global implications: “China’s desert solar model could be replicated in similar environments worldwide. The Sahara alone could theoretically host enough solar capacity to meet global electricity demand four times over while potentially greening up to 20% of the desert.”

The Chinese government has responded by implementing policies promoting “solar energy + sand control” and “solar energy + ecological restoration” initiatives. These efforts have shown promising results, with over 92% of PV plants constructed since 2017 incorporating at least one ecological construction mode.

Studies at facilities like the Qinghai Gonghe Photovoltaic Park demonstrate that areas under solar panels score significantly better in environmental assessments compared to surrounding regions, indicating positive effects on local microclimates.

As the world grapples with dual climate and biodiversity crises, China’s desert solar experiment offers a compelling model for sustainable development. The findings suggest that renewable energy infrastructure, when thoughtfully implemented, can serve as a catalyst for environmental regeneration, potentially transforming the world’s deserts from barren wastelands into productive, life-supporting ecosystems.

“This is no longer just about energy production,” concludes Dr. Liu. “We’re witnessing the birth of a new approach to ecosystem rehabilitation that could transform how we think about desert landscapes globally. The next decade will be crucial as we scale these solutions to meet both our climate and biodiversity goals.”"

Living in Florida (or anywhere in the southeast USA tbh) and NOT being into birds is like walking into a giant banquet hall feast with every single most delicious food you could ever imagine laid out in front of you only for you to say “oh I’m not hungry” and walk out without taking a bite

I need you all to appreciate how crazy it is to have watched the scimitar horned oryx go from a poster child for "it only exists in zoos" to merely endangered (not even critically endangered!) over my lifetime.

So many heroic people contributed ridiculous amounts of time and effort to make this captive breeding and reintroduction effort a success.

Står stolt, akvarell, 26,5x36 cm Det här och mina två senaste inlägg är målningar av skogar som är anmälda för slutavverkning. Delar av dem är enligt Skogsstyrelsen skog med höga naturvärden och nyckelbiotop. Det finns fynd av rödlistade och fridlysta arter i de här skogarna. Nu riskerar de, precis som 80% av alla skogar som huggs ner i Sverige, att bli pappersmassa eller andra kortlivade produkter som bränns upp inom två år.

Standing tall, watercolour, 26,5x36 cm This and my two latest posts are paintings of forests that are notified for logging. Parts of them are defined as having high natural values and being a key biotope by the Swedish Forest Agency. There are findings of several redlisted and protected species in these forests. Now, like 80% of the forests that are cut down in Sweden, they risk being turned into paper pulp or some other short lived product that will be burned withing two years.

During my internship, I saw another strange fellow. If you like the neck flexibility of the European wryneck you sure gonna love the Little bittern (Ixobrychus minutus). This bird is in the heron family (Ardeidae) but loves to shrink itself. But be warned ! They know where your eyes are and can launch their neck and beak real fast ! One tried to attack me while I was checking its ring and I was lucky to be just 10 cm too far. Despite this vicious attack I love this funny bird and he was quite easy to untangle and to ring. With colleagues, we nicknamed it the "Accordion of death"

"In 2021, scientists in Guelph, Ontario set out to accomplish something that had never been done before: open a lab specifically designed for raising bumble bees in captivity. 

Now, three years later, the scientists at the Bumble Bee Conservation Lab are celebrating a huge milestone. Over the course of 2024, they successfully pulled off what was once deemed impossible and raised a generation of yellow-banded bumble bees. 

The Bumble Bee Conservation Lab, which operates under the nonprofit Wildlife Preservation Canada, is the culmination of a decade-long mission to save the bee species, which is listed as endangered under the Xerces Society for Invertebrate Conservation...

Although the efforts have been in motion for over a decade, the lab itself is a recent development that has rapidly accelerated conservation efforts. 

For bee scientists, the urgency was necessary. 

“We could see the major declines happening rapidly in Canada’s native bumble bees and knew we had to act, not just talk about the problem, but do something practical and immediate,” Woolaver said. 

Yellow-banded bumble bees, which live in southern Canada and across a huge swatch of the United States, were once a common species.

However, like many other bee species, their populations declined sharply in the mid-1990s from a litany of threats, including pathogens, pesticides, and dramatic habitat loss. 

Since the turn of the century, scientists have plunged in to give bees a helping hand. But it was only in the last decade that Woolaver and his team “identified a major gap” in bumble bee conservation and set out to solve it. 

“No one knew how to breed threatened species in captivity,” he explained. “This is critically important if assurance populations are needed to keep a species from going extinct and to assist with future reintroductions.”

To start their experiment, scientists hand-selected wild queen bees throughout Ontario and brought them to the temperature-controlled lab, where they were “treated like queens” and fed tiny balls of nectar and pollen. 

Then, with the help of Ontario’s African Lion Safari theme park, the queens were brought out to small, outdoor enclosures and paired with other bees with the hope that mating would occur. 

For some pairs, they had to play around with different environments to “set the mood,” swapping out spacious flight cages for cozier colony boxes. 

And it worked. 

“The two biggest success stories of 2024 were that we successfully bred our focal species, yellow-banded bumble bees, through their entire lifecycle for the first time,” Woolaver said. 

“[And] the first successful overwintering of yellow-banded bumble bees last winter allowed us to establish our first lab generation, doubling our mating successes and significantly increasing the number of young queens for overwintering to wake early spring and start their own colonies for future generations and future reintroductions.”

Although the first-of-its-kind experiment required careful planning, consideration, resources, and a decade of research, Woolaver hopes that their efforts inspire others to help bees in backyards across North America. 

“Be aware that our native bumble bees really are in serious decline,” Woolaver noted, “so when cottagers see bumble bees pollinating plants in their gardens, they really are seeing something special.”"

Did you know? Chimpanzees (Pan troglodytes) are among humans’ closest non-human relatives. In fact, they share about 98 percent of genes with Homo sapiens! These primates are one of the widest-ranging great apes and can be found throughout parts of central Africa, including Senegal, Tanzania, and Uganda. They tend to live in tropical forests, but might also be spotted in woodlands, savannas, or mountain forests. Their ability to make and use tools to aid them in solving problems—like sticking a branch into an ant hill to help it fish out some snacks—is just one of many examples of chimps’ complex behaviors that have fascinated scientists for decades.

Endangered Species Sightings from This Year

This is thought to be the first time in over 20 years that a blue whale was spotted off the Coast of Massachusetts.

I highly recommend watching the video and listening to the reaction of the people on the whale watching boat--the cheers and emotion in some of their voices, especially the woman saying "I'm trying not to" when someone jokingly tells her not to cry.

This is the first time ever that a mother clouded leopard with two cubs has been spotted on a game cam!

"After being considered regionally extinct for over a century, giant anteaters have been spotted roaming once again in Brazil's Rio Grande do Sul state. Scientists have concluded these returned natives ventured over from Argentina's Ibera Park, where conservationists have released around 110 rescued and captive-bred anteaters since 2007."

Over 100 years and the anteaters are finally coming home!
