Distribution

Gomortega keule grows only in a very narrow habitat range in coastal Central Chile, including the Maulino forest and parts of the Chilean matorral. It is a characteristic tree species of the Maulino forest alongside Nothofagus glauca, Nothofagus × leoni, and Nothofagus alessandrii.

The species is threatened by habitat loss. The Maulino forest has mostly been cleared for agriculture and tree plantations of Pinus radiata and Eucalyptus globulus. The species' remaining habitat is fragmented, and its populations isolated. It has been affected by fires, including the 2017 Chile wildfires. Populations are protected at Los Queules National Reserve and Los Ruiles National Reserve.
