It flourishes on loose infertile sites and suckers freely which helps bind the soil together. If planted on riversides it can assist in preventing banks being washed away.
It is commonly planted on reclaimed industrial spoil heaps for, as with common alder, it fixes nitrogen from the air and improves the fertility of the site
