Dwarf Birch, also known as Bog Birch for its common occurrence in wet areas, is a small deciduous shrub native to North America.

Found growing up into the arctic circle, this is one of the few trees that grows that far north.

Common in riparian zones and boreal forests across Western Canada. It is a common reclamation species.

This species is often used by local artisans to twist into shapes like willow and make decorative hearts, circles, etc.

Red Alder is a fast-growing deciduous tree native to western North America. Its fixes nitrogen, which enriches soils and supports the growth of surrounding plants. Ideal for sites with poor soil conditions, or areas disturbed by logging, construction or fire.
It provides shade in riparian areas, creating cover for fish. Its seeds and buds are eaten by birds and small mammals, while the foliage provides browse for wildlife. The catkins release clouds of pollen attracting bees and other insects.
The Red Alder gets its namesake from the rusty-red color the bark turns when bruised.
