Latin Name:  Alnus tenuifolia
Common Name:  Mountain alder
Family:  Betulaceae
Author:  Nutt.

Known Hazards:  The freshly harvested inner bark is emetic but is alright once it has been dried[172].

Mature Height:  9   Mature Width:

Habitat:  Moist soils by swamps, streams, ponds and lakes in foothills to well up in the mountains[60, 229].

Cultivation Notes: Prefers a heavy soil and a damp situation[1, 11]. Grows well in heavy clay soils[11]. Tolerates very infertile sites[200]. A fast-growing but short-lived tree[229]. There is some confusion over the correct name of this tree with one authority citing the European species A. incana as the correct name[60]. Another report says that this species is closely related to A. incana, but distinct[229]. This species has a symbiotic relationship with certain soil micro-organisms, these form nodules on the roots of the plants and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200].
