Last month I wrote about the 86% decline in populations of migratory fish since 1970. Turns out that was just a trailer for the feature film.
In September, WWF released its Living Planet Report, which includes the grim statistic that essentially all vertebrate species that depend on freshwater ecosystems are following the same precipitous plunge as migratory fish.
How the world developed its energy systems, particularly hydropower dams that fragmented rivers, is one of the primary reasons for this dramatically dropping trendline.
How the world designs, builds and operates its future energy systems will be key to halting, and ultimately reversing that trendline.
The current decline in freshwater populations is tracked by the “Living Planet Index” (LPI), which provides insights into the health of global wildlife, much like an index fund provides insights into the health of financial markets. And just as an index fund reflects the prices
An interactive map developed by the Environmental Justice Atlas team at the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) reveals that certain forms of wildlife conservation undermine the rights of indigenous people and local communities living within protected areas across India.
The interactive map, led by ICTA-UAB researcher Eleonora Fanari and carried out in collaboration with India’s environmental organization Kalpavriksh, has been launched during the India’s National Wildlife Week. The map is a product of three years of extensive research covering 26 protected areas, carried out in association with numerous organizations, activists and independent scholars, struggling against violations across the ground and in the courts.
A strict protect-and-conserve model, favored by a powerful Indian conservation lobby, has increased the network of protected areas from 67 in 1988 to 870 in 2020. However, these lands

Scientists have long deployed drones to do everything from counting caribou to collecting whale snot. Now the flying machines are helping to rescue animals as climate change takes an increasingly deadly toll on wildlife.
For the past year, a California videographer named Douglas Thron has chased climate catastrophes around the world, piloting drones outfitted with infrared cameras and spotlights to help find survivors of hurricanes and firestorms whose frequency and intensity are growing with rising temperatures. After Thron locates the animals, wildlife rescuers can move them to safety.
“The potential for these drones to save animals, whether wild or domestic, and

Long-Term Data Sets for Biodiversity Monitoring, Research, and Management
John Sauer and others: Biometrics for Complex Long-Term Biodiversity Data Sets: Lessons from the Breeding Bird Survey
John R. Sauer; William A. Link; James E. Hines–Most of our understanding of changes in avian biodiversity in North America is based on analysis of population change from the North American Breeding Bird Survey (BBS). The BBS provides data at spatial scales ranging from individual survey locations to continental, but analyses at all scales are complicated by the need to accommodate detectability issues during sampling and changes in sampling effort over space and time. Over the years of
The COVID-19 pandemic has fired up interest in outdoor activities in our parks and forests. Now a new UBC study highlights the need to be mindful of how these activities may affect wildlife living in protected areas.
Researchers placed motion-activated cameras on the trails in and around the South Chilcotin Mountains Provincial Park in southwestern B.C., a region popular for its wildlife and recreational activities such as hiking, horseback riding, ATV riding and mountain biking. Overall, they found that environmental factors—like the elevation or the condition of the forest around a camera location—were generally more important than human activity in determining how often wildlife used the trails.
However, there were still significant impacts. Deeper analysis of trail use captured by the cameras showed that all wildlife tended to avoid places that were recently visited by
Kids will be able to see and learn more about native Hudson River wildlife and more.
Today, the Hudson River Park Trust’s River Project unveiled a jam packed lineup of virtual lessons as part of their annual SUBMERGE Marine Science Festival on Thursday, September 24. The marine science festival that usually brings kids of all ages to the New York City waterfront will instead host a full day of interactive virtual science available to anyone, regardless of location.
This marine-focused STEM (Science, Technology, Engineering and Math) festival covenes educators, scientists and performers to bring marine science to life, including along the city’s waterways. By incorporating a wide range of fun, interactive educational activities, the festival aims to engage children with marine science and help them learn about the ecological importance of Hudson River Park’s 400-acre unique Estuarine Sanctuary.
“Every year we bring science to life for students in all five
