Useful plants

Wood, fibre, shelter and craft

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.

Alders

Alnus spp.

Useful plants

Identify: Oval toothed leaves; catkins; woody cone-like female structures persist through winter.
Habitat: Wet thickets, streambanks, avalanche tracks and disturbed forest.
Season: Wood year-round; leaves growing season.
Field use: Straight stems for racks and wattle; seasoned alder burns evenly and is widely used as smoking wood.
Caution: Wet alder smokes heavily; dense thickets can hide unstable banks.
Look-alikes: Birch lacks persistent woody cones.

Dogwoods

Cornus spp.

Useful plants

Identify: Usually opposite branching; arcuate leaf veins curve toward the tip; clustered flowers and drupes.
Habitat: Forest edge, riparian thicket and mountain slope.
Season: Stems year-round; fruit varies by species.
Field use: Dense straight shoots make excellent arrow shafts, skewers and pegs.
Caution: Fruit edibility varies greatly; some species cause stomach upset. Use as material unless species is confirmed.
Look-alikes: Viburnums may have opposite leaves but different veins and buds.

Common reed

Phragmites australis

Useful plants

Identify: Tall jointed canes; broad leaves with rough margins; large feathery purple-tan panicles.

Aquatic edibles

Water-margin food species

Cattails

Typha spp.
