Rainbow Eucalyptus
Definition
The rainbow eucalyptus (Eucalyptus deglupta), known in the Philippines as bagras, is a fast-growing rainforest tree famed for its trunk, which sheds bark in patches to reveal streaks of green, orange, purple, and brown. It is native to Mindanao and other parts of the humid Southwest Pacific and is the only eucalyptus that occurs naturally in the rainforests of the northern hemisphere.

Examples and Analogies
Where most eucalypts wear a single sober coat, the rainbow eucalyptus molts like a snake in public: each peeled patch ages through its own color, so a plantation row looks like sharpened pastel pencils lined up in a cup — a living palette rather than a painted one.
Usage Scenarios
In the Philippines the species is planted in industrial tree plantations for pulp and in Bukidnon and Mindanao reforestation projects; abroad it decorates parks in Hawaii and Florida; and photographers seek mature stands along the Halsema Highway and Bukidnon roads where the trunks are most vivid.
Strategies
Management strategies include its use as a fast-growing plantation species on short rotations, breeding programs for pulpwood, careful siting away from water-stressed areas, and promotion as a living landmark in ecotourism routes where its color draws visitors.
Security and Safety Measures
Plantation protocols address fire risk and soil effects typical of eucalypts, harvest rules follow forestry codes, and because it naturally grows in rainforest climates it is sited where it cannot dry out — protecting both crop investment and surrounding native forest edges.
Historical Context
The species was described from Pacific material in the 19th century, and its heartland includes New Guinea, Sulawesi, and Mindanao — making the Philippines one of its natural homes rather than an adoptive one. In the 20th century it became a plantation tree across the humid tropics, and its painted trunk made it a global ornamental celebrity.
Challenges and Controversies
Debates include the plantation-versus-native-forest question common to fast-growing exotics (and to its own native-range plantations), concerns about eucalypt water use in drier sites, and the risk that its celebrity leads to indiscriminate planting outside suitable climates.
