Spotless tree toads could make Shanghai comeback

Conservationists trial-release species disappeared from city two decades ago

Editor's note: As protection of the planet's flora, fauna and resources becomes increasingly important, China Daily is publishing a series of stories to illustrate the country's commitment to safeguarding the natural world.

The spotless tree toad, a species endemic to China and once lost to Shanghai for more than two decades, is on the pathway to being reintroduced to the city's lakes, fields and farmland.

These toads, sometimes called the Chinese immaculate treefrog, play a pivotal role in controlling insect populations, nutrient cycling and serving as an indicator of overall ecosystem health.
