In flat areas balsam fir grows fast, tall, and large, mixed with red spruce. Hardwood slope – ground rot is common in this well-drained area, and leaf litter covers the forest floor. Balsam firs grow fast, tall, and large along with big hardwood trees such as yellow birch, sugar maple and beech.
Populus balsamifera is the northernmost North American hardwood, growing transcontinentally on boreal and montane upland and flood plain sites, and attaining its best development on flood plains. It is a hardy, fast-growing tree which is generally short lived, but some trees as old as 200 years have been found. [7]

Populus section Tacamahaca – balsam poplars (North America, Asia; cool temperate) Populus angustifolia – willow-leaved poplar or narrowleaf cottonwood (central North America) Populus balsamifera – Balsam poplar (northern North America) (= P. candicans , P. tacamahaca )
While red spruce is common throughout North America, the Fraser fir—a relative of the balsam fir—is found only in the spruce–fir stands of southern Appalachia. [5] In the second half of the 20th century, nearly all of the mature Fraser firs were killed off by the balsam woolly adelgid—a parasite introduced from Europe around 1900. [6]

Populus trichocarpa, the black cottonwood, [1] western balsam-poplar [2] or California poplar, is a deciduous broadleaf tree species native to western North America. It is used for timber , and is notable as a model organism in plant biology .
The balsam poplars are light-demanding trees that require considerable moisture. Balsam poplars are tolerant of very cold conditions, occurring further north than other poplars except for the aspens. The poplars in Southern California are tolerant of 100 plus degree heat. They grow along dry washes and dry riverbed's.
