Where does this species come from?
Hakea drupacea is endemic to coastal regions of south-western Australia and some islands in the adjacent Recherché Archipelago. The natural vegetation where Hakea drupacea occurs is evergreen forest and xerophilous woodland with a Mediterranean-type climate.
Why is it a problem?
Hakea drupacea is a serious invader of the floristically rich and unique mountain fynbos in the Western Cape Province, South Africa. Dense stands of woody alien plants can alter the composition of natural plant and animal communities. They also lead to increased fire intensities that may kill plant species that regenerate vegetatively and seeds on or in the soil. The most obvious impact of dense stands of H. drupacea on the native vegetation is the reduction in species richness and the altered appearance of the landscape.
Means of reproduction?
Spread by seed. Some species sucker from the roots.
