The lost generation of ancient trees

Ancient trees like the Big Belly Oak, which grows to be hundreds of years old, provide substance to thousands of invertebrate species, and hundreds of species of lichen and fungi. However, due to changes in forest management and agriculture, many of the ancient trees are not surviving long enough to age. It's crucial for them to age because that's when many species of fungi and insects begin to move into their core. In order to speed up the aging process scientists are trying two methods, veteranisation and inserting fungi into trees.
