The fruiting cones resemble small pine cones and are very attractive to a number of birds. It is also beneficial for the threatened Canadian giant moth (mnfi.anr.msu.edu/). Speckled Alder spreads by rhizomes and can form thickets if the conditions are right, so be mindful of planting, especially in open fens and bogs.
