Elk, bear, frogs and other animals have used the overpass, which connects 39,000 acres of habitat, since its completion

Colorado officials have tracked herds of elk, bears, pronghorn and even northern leopard frogs ambling across its new wildlife overpass. According to a newly released report, the overpass, which acts as a bridge over a busy stretch of interstate, has helped cut wildlife-vehicle collisions by 91% since its completion 10 months ago.

The overpass is the centerpiece of a larger system built by the state to assist wildlife crossing the highway, which also includes miles of 8-ft tall fencing and five large wildlife underpasses.

As Cop17 kicks off, records since 1921 show more bee species declining than increasing in all parts of Europe except the Alps

Most of Europe’s wild bee species and about half of its hover fly species have declined over the last century, a study has found, as a UN biodiversity summit begins in Armenia.

Records since 1921 show more bee species are declining than increasing in all parts of Europe except the Alpine region. The richness of bee and hover fly species suffered a persistent drop in the Atlantic and Continental regions, the study found, though trends in other regions were mixed or even positive.

Dutch MEP says government is trying to avoid EU environmental rules as protests over luxury development turn violent

MEPs have accused Albania of deploying “sneaky” practices to fast-track a proposed Trump-linked luxury resort in the country amid protests that have turned increasingly violent.

As the prime minister, Edi Rama, pledged to “listen to the voices of young people” taking to the streets, there was mounting criticism of his failure to address demonstrators who had long opposed the controversial project peacefully.

Four years ago nearly every government on Earth agreed to protect nature. Now, as countries gather for Cop17, the pressure is on to follow through on those commitments

• Cop17 at a glance: everything you need to know about the UN’s nature summit

Passersby could smell the dead fish before they saw them. In August, more than 3,000 pike, roach, carp and rudd were found lifeless along the River Wensum in Norwich. Some gasped for air in their final moments, desperate for the oxygen that heatwave conditions had depleted in the water. Investigators believe that the die-off was triggered by heavy rainfall that flushed through high concentrations of pollution at a time when wildlife were already struggling.

The 45-mile (70km) chalk river is one of about 250 in the country. They are a geological accident almost unique to Britain – and one of Earth’s rarest habitats. They emerge from chalk aquifers and are home to species such as freshwater shrimp, otters and stoneflies, also providing drinking water for millions of people. But just 11 have formal protection, with many ravaged by sewage pollution and overextraction. The Norfolk river is one of the few that does have legal protection, but it is in poor ecological health.

This month’s biodiversity summit in Yerevan, Armenia, aims to push governments to meet the 23 targets agreed at Cop15 in 2022

• Can countries deliver on a deal to save the world’s plants and animals?

This month, nearly every country on Earth will return to the question of how to stem the rapid destruction of the natural world. Humans are driving it, but so far we have not found a way to stop it.

In late 2022, governments reached an ambitious once-in-a-decade deal to better protect nature amid scientific warnings that the planet is going through the largest loss of life since the extinction of the dinosaurs. Now, they are assessing their progress on the targets for the first time.
