Population statistics

The Hazel is a member of the birch family of trees, Betulaceae, and can grow to a height of 30 feet. Typically it has a number of shoots or trunks branching out at ground level, which has led to some people referring to it as a bush as it doesn't meet the strict definition for a tree of having a single stem unbranched near the ground. This ability to produce multiple stems gives it a dense, spreading appearance and has led to it being used extensively for coppicing. Usually living for between 50 and 70 years, if it is coppiced it will live much longer, up to several hundred years.
