Useful plants

Wood, fibre, shelter and craft

Eucalypts

Eucalyptus / Corymbia spp.

Useful plants

Identify: Oil-dotted aromatic leaves; bark may be smooth, fibrous, stringy or flaky; woody capsule “gumnuts.”
Habitat: Australian forests, woodland and savanna; planted worldwide.
Season: Wood and bark year-round; flowers seasonal.
Field use: Hard wood for bows, spear shafts, handles and fuel; shedding bark can be tinder; hollow limbs may hold water only after careful inspection.
Caution: Many species are extremely hard and split dangerously. Oils and leaves are not food; fire behavior is intense.
Look-alikes: Melaleuca has papery bark and bottlebrush flowers.

Paperbarks

Melaleuca spp.

Useful plants

Identify: Papery layered bark; narrow oil-dotted leaves; cream bottlebrush flower spikes and woody capsules.
Habitat: Australian wetlands, monsoon forest, swamp and coast.
Season: Year-round bark and wood.
Field use: Loose outer bark is excellent tinder, wrapping and temporary waterproofing; wood makes poles and fuel; some species yield tea-tree oils.
Caution: Do not ring-bark living trees. Essential oils are concentrated and not for drinking.
Look-alikes: Eucalypts have gumnuts and different bark; bottlebrush Callistemon forms are related.
