Climbing broom Carmichaelia kirkii

Key Features

Native brooms in the genus Carmichaelia have a variety of growth habits, from small trees to low-growing shrubs, and even one climbing species. They have characteristic ‘pea flowers’ which can be very showy in some species. Many grow in areas that have potential for afforestation, and most are susceptible to browsing by stock and feral animals. As a consequence, several species are threatened.

• A scrambling or climbing broom with thin, green or bronze branches, sometimes bearing small leaves but often leafless.
• Large, purple-streaked, white flowers.
• Mottled seeds within a beaked pod.

Distribution and Habitat

• South Island east of the Main Divide from Marlborough to Otago.
• Habitat is grey scrub communities, often on toe slopes and gully sides.

Threats

• Habitat modification and loss.
• Stock browse.
• Fire.
• Inappropriate weed spraying.

Management Opportunities

• Survey for new locations.
• Mark known sites, and avoid spraying them.
• Protection of habitat.
• Translocate or reintroduce to appropriate sites.
• Ensure that forest owners are aware of potential habitats and can recognise the species.

Monitoring

• Check existing populations annually.
• Report new locations to DOC, NZPCN.
