Hedgehog Bramble

Rubus echinatus

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Hedgehog Bramble faces severe pressure from agricultural expansion and urban development across its limited range in the Hawaiian Islands. Invasive plant species, particularly aggressive non-native brambles and grasses, compete directly for habitat space and resources. Climate change poses an additional threat through altered precipitation patterns that affect the moist forest conditions this species requires for survival.

Threat summary

Habitat

Rubus echinatus inhabits moist montane forests and forest edges in the Hawaiian Islands, typically growing in partially shaded areas with well-drained volcanic soils. The species thrives in elevations between 300-1,200 meters where consistent moisture levels support its growth requirements.
