Tree Biology Facts

We produce the carbon dioxide that trees breathe. In return, they give us the oxygen that we breathe. Nature is amazing!

When leaves begin to change colour in the autumn, the tree releases hormone designed to take the last sugars out of the tree to help it through the winter.

Cells in a tree are known as Cambium and those inside the bark are known as Xylem (woody) and darker, tougher hardwood is made from dead cells reinforced with lignum, tannins and other toughening chemicals. The cells on the outside are known as Pholem and transport water, sugars and minerals through the bark.

Most trees grow with a slight spiral twist in the trunk, which makes them extra strong against wind shearing, i.e. stops them bending.

Acorns and nuts (especially from Beeches) fall directly beneath the tree, but are carried by Jays to other areas.

Following thousands of additions in recent years, over 70,000 tree species are confirmed to exist worldwide, which is quite amazing! Sadly, global warming currently threatens some 18,000 of them.

Ivy, which commonly grows on trees, was often featured on premises to indicate that they made or sold beer.
