Birds eat the fruit from the mountain-ash and they spread seeds, helping new trees to grow.
The American mountain-ash is a small tree, up to 10 metres tall. It grows across Ontario, south of Hudson Bay. Its leaves have 13 to 17 leaflets which are 5 to 10 centimetres long, with toothed edges.
In May and June, the tree is covered in clusters of white flowers. Later in the summer, bunches of bright orange-red berries appear, 4 to 6 millimetres in diameter.
The American mountain-ash prefers moist ground but can also grow in rocky and dry soil, but it will be more stunted on rocky sites.
