Useful plants

Wood, fibre, shelter and craft

Dwarf birches

Betula nana / B. glandulosa group

Useful plants

Identify: Low many-branched shrub with small rounded toothed leaves and tiny catkins.
Habitat: Arctic heath, bog margins, alpine slopes and snow-catching hollows.
Season: Growing-season leaves; twigs year-round.
Field use: Fine twigs make brush bedding, small bundles and light screens; dense patches trap snow and mark slightly raised ground.
Caution: Slow-growing and important for soil stability. Harvest sparingly and never strip large tundra patches.
Look-alikes: Dwarf willows often have narrower leaves; young alder has larger catkins.

Willows

Salix spp.

Useful plants

Identify: Alternate narrow to oval leaves; flexible twigs; catkins; many species root along wet ground.
Habitat: Riverbanks, lake margins, floodplains, tundra valleys and moist forest.
Season: Twigs year-round; leaves and catkins in the growing season.
Field use: Flexible rods for baskets, fish traps, wattle, arrow shafts and repair splints. Dry punky willow and softer species can serve bow-drill hearth boards; denser pieces make spindles. Bark has documented salicylate-related traditional use.
Caution: Species identification is difficult. Do not self-dose bark with aspirin allergy, bleeding risk, kidney disease, pregnancy, or in children with viral illness.
Look-alikes: Alders have cone-like female catkins; some dogwoods have opposite leaves.
