Switzerland has reversed the decline of more than half of endangered frogs, toads, and newts in one region, research finds.

เล่นสล็อต It's going to be a lot of people playing games each day. But if we only define 100 people, about 20% of the hundred integers are still unable to capture the desired target.

After conservationists dug hundreds of new ponds in the state of Aargau, amphibian numbers significantly increased.

The European tree frog population in particular "exploded", scientists say.

Scientists hope this method could be used globally as pond building is simple and effective.

Globally amphibian populations are in significant decline due to factors including habitat loss, urbanisation, road infrastructure, disease and invasive species.

In 1999 Aargau decided that a mass conservation effort was needed to combat the loss of amphibians. The collapse of the European tree frog was of particular concern.

State authorities, non-profit organizations, private landowners and hundreds of volunteers worked for 20 years to build 422 ponds in five regions in Aargau.

Older ponds had become unsuitable for some amphibians due to lack of space, a high number of predators, and dense vegetation.

By creating new ponds, the conservationists gave the species more space to thrive.
