Mystery plagues Valais forest
A village in Valais is asking for federal help as a major part of a local forest seems to be dying - and no one knows why.
The patch of pine forest over 25 hectares is turning brown. But trees around the affected patch remain healthy.
One national MP, Jean-Paul Gschwind, says the federal government needs to investigate.
It's not sure if the sick forest is down to a drought or disease. But all locals agree it's very unusual.
