Bushes are more widely distributed in nature and on earth than trees. A new study explains why bushes are so successful worldwide. The key is their many stems. This increases both growth and survival rate compared with trees, according to researchers at the University of Gothenburg, Chalmers University of Technology and Linnaeus University.
Bushes with flowers and berries are popular in our gardens and parks, and in the wild they have a global distribution significantly larger than trees. They are present on at least 40 per cent of the Earth’s land surface, while trees occupy only 28 per cent of the land area. Still, few have attempted to understand bushes as a plant form.
