Trees and woods are crucial. They provide homes for wildlife, clean air and water, food and fuel - but they're under threat.
60 million trees have been taken by Dutch Elm disease. 126 million trees in British woods at risk of ash dieback. 19 pests and diseases are attacking our native trees, six have reached epidemic levels. And at least 11 more diseases are nearing our borders.
