Eucalyptus deglupta

+ Tree Family

Myrtaceae

+ Ecology

Native to Philippines, Moluccas, and New Guinea. It occurs in dense stands that are commonly found along rivers where it has colonized newly formed banks and non-stagnant river flats. Also found on sites that have been cleared or disturbed by landslides, volcanic eruptions, shifting cultivation etc. It grows in moderately humid to very humid subtropical and tropical climates, generally areas with annual lows of 13 to 25 °C, annual highs of 24 to 35 °C, annual rainfall of 1300 to 7000 mm.

+ Description

A huge evergreen tree growing up to 60 metres tall, with occasional specimens up to 75 metres. The bole, which can be up to 240cm in diameter, is generally of good form, comprising 50 - 70% of the total tree height, sometimes with buttresses 3 - 4 metres tall.

BARK: smooth, shed unevenly in strips, revealing the bright green new bark, which then darkens as it matures to give blue, purple, orange and then maroon tones. 

LEAVES: juvenile leaves opposite, ovate to lanceolate; adult leaves opposite to subopposite, rarely alternate, shortly petiolate, held almost horizontal on branches, ovate to ovate-lanceolate or acuminate, thicker than juvenile leaves.

FLOWERS: 3 - 7 umbels in terminal or axillary panicles. Pedicels terete or slightly angular, about 5mm long; young buds small, green with double opercula; developed buds pale green or cream, globular. Operculum hemispherical; flowers with many white to pale yellow stamens 0.2-1cm long.

FRUITS:  small, thin capsule with 3 or 4 exserted (protruding) valves, making the capsule appear globular and disc-shaped. Mature fruits furn from brown to dark brown, containing 3-12 well-formed seeds per valve. Seeds tiny, brown, flattened, with a small terminal wing.

+ Uses

Eucalyptus deglupta is a major plantation tree for pulp production; both the wood and bark are good sources of pulp.

The wood is valuable timber, suitable for light and heavy construction, flooring, furniture, joinery, moulding, boat building, posts, poles, veneer, plywood, particle board, hard board and wood-wool board, hand and machine tools.

It is also used as fuel wood and for charcoal making, but is normally considered too valuable for these purposes.

Eucalyptus deglupta is widely planted as an ornamental tree because of its attractive bark.

Agroforestry: the tree is used for land reclamation, reforestation and forest enrichment planting, provides bee forage.

An ornamental tree

+ Propagation

Seeds, cuttings

+ Management

Fast growing. Plantations for saw-logs require thinning Eucalyptus deglupta does not coppice well after cutting and must be replanted.

+ Remarks

Eucalyptus deglupta is endangered in parts of its natural range due to loss of habitat and logging for timber and firewood. It is the only Eucalyptus species adapted to lowland and lower montane rain-forest habitats. Due to its very attractive bark and quick growth, the species is frequently planted as an ornamental tree.
