Scientists are checking up on the health of forests by analysing the sounds in them. They test their vital signs by measuring the croaks, tweets and hums of resident creatures. If they can hear a full range of animals they can be confident an ecosystem is doing well. However, if gaps start to appear, it’s a sign something is up.

Nick Holland hears more about how it works and how it’s being used to strike a balance between the needs of Papua New Guinea’s growing indigenous communities and the need to preserve the biodiversity of the forests they live off. Produced and presented by Nick Holland Image: The Nature Conservancy

Back from the brink: Uganda’s gentle giants

The eco-tourism that is helping to protect mountain gorillas in Uganda.

Myra Anubi is in Uganda visiting the Bwindi Impenetrable Forest. It’s one of the few places that gorillas still exist in the wild, and even better, in recent years their numbers have actually been rising and they are no longer considered critically endangered.

This is partly down to the hard work of Dr Gladys Kalema-Zikusoka and the Conservation Through Public Health organisation. They engage with communities living close to the gorillas, who were often poaching them and destroying their habitat, to help them better understand the animals and tap into the potential for eco-tourism. They also encourage other forms of enterprise, supporting local coffee farmers with training and investment.

Myra meets former poachers now involved in conservation and speaks with local farmers - often women - who look after the coffee plantations. She talks to the village conservation teams involved in protecting the gorillas. And of course, goes into the forest to get a glimpse of these incredible creatures herself.
