Pittosporum dallii
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Pittosporum dallii faces significant pressure from habitat degradation due to agricultural expansion and urban development across its limited range in New Zealand. Invasive plant species compete directly with native populations, while browsing by introduced mammals damages regeneration. The species' naturally fragmented distribution makes remaining populations particularly vulnerable to local extinctions from these combined pressures.
Habitat
This endemic New Zealand shrub occurs in coastal and lowland forest margins, scrublands, and rocky outcrops, typically on well-drained soils. It favors disturbed forest edges and regenerating native vegetation communities at elevations from sea level to approximately 600 meters.
