Useful plants

Wood, fibre, shelter and craft

South American mountain bamboo

Chusquea spp.

Useful plants

Stylized form diagram for South American mountain bamboo

Identify: Solid or nearly solid segmented culms; dense branching at nodes; narrow grass leaves.
Habitat: Andean and Atlantic montane forest, often forming thickets.
Season: Culms year-round; shoots seasonal.
Field use: Arrow shafts, basketry, shelter lattice, containers and friction-fire spindles; shoots of selected species require expert preparation.
Caution: Dense thickets hide cliffs and animals. Some bamboos flower and die en masse.
Look-alikes: Reeds are hollow and rooted in wetlands rather than woody mountain thickets.

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.

Habitat: Cold flowing springs and streams, often where nutrient-rich.
Season: Cool seasons.
Field use: Tender tops are documented food and are usually cooked in survival settings.
Caution: Raw watercress can carry liver flukes and sewage pathogens. Avoid downstream of livestock, roads or settlements.
Look-alikes: Water hemlock has divided leaves and umbrella flowers; never rely on habitat alone.
