About plant names...
Alders are small to medium in size, often with multiple trunks and branches. Green alders rarely exceed
15′ (4.6 m) in height, about haf the size of other alders, a woody shrub rather than a tree. These fast-growing
shrubs are often found beside wet areas.
They are also common on mountains, especially in avalanche-prone regions, where their ability to regrow
from damaged stumps
allows them to out-compete other trees.
Identification: Green alders have
lenticels —white or light gray patches, that are roughly diamond-shaped. See Alnus for
a comparison table.
