Smooth alder is used predominantly for streambank stabilization and

wetland restoration. It is also a critical cover component of woodcock habitat.

Compared to other alder species, 
smooth alder is more densely branched and produces
more seed. Alders produce nitrogen for themselves
by the activity of nitrogen-fixing bacteria located in
root nodules. For this reason, it is not recommended
for planting in areas where additional nitrogen might
add to water quality problems.

Adaptation and Distribution
Smooth alder grows best in wet bottomlands and stream margins,
however it will also grow in well-drained upland
areas. It is moderately shade and acid tolerant, but is
weak-wooded and susceptible to wind and ice
