Smooth Sumac is a pioneer plant. This means it is one of the first plants to take over a field. Later, taller trees will push out the sumac.

This shrub may only live a few years.

Smooth Sumac depends on birds and animals to spread its seeds by pooping them out in new places. Then, new shrubs can grow.
