of National Parks 2008). Lantana was introduced to Norfolk Island in 1905 as an ornamental horticultural species and is now widespread probably due to birds dispersing the seeds. It is found on Phillip Island in low abundance but could be eradicated with targeted weed control and monitoring to detect new populations (Mills 2009b).

William Taylor (Ageratina riparia)

Also known as mist flower, this weed species was introduced to Norfolk Island as a garden plant. It grows to one metre high with white flower heads and spreads widely, shading out small native plants. It is found in areas open to the wind and with full sunlight. The weed dominates the understorey in some parts of the national park (Director of National Parks 2008) and is also found on Phillip Island (Mills 2009b; J Christian 2024, pers comm 11 January).

Kikuyu (Cenchrus clandestinus)

Kikuyu is an exotic grass introduced to Norfolk Island for pasture. The species was used to stabilise open areas, roadsides and rehabilitation areas in the national park (Director of National Parks 2008). Kikuyu severely restricts regeneration of native plant species, particularly in the national park and public reserves, as it forms a thick sward that is almost impossible for seedlings to penetrate.
Competition from kikuyu and other imported grasses such as buffalo grass (Stenotaphrum secundatum) and couch grass (Cynodon dactylon) may prevent the re-establishment of pines and other species (Benson 1980). The thick sward and deep runners of kikuyu have the potential to degrade the habitat for ground nesting seabirds such as wedge-tailed shearwaters and other burrowing petrels. The grass constricts burrow entries and has been reported to strangle birds on Lord Howe Island (DECC NSW 2007). Kikuyu is not a major weed on Phillip Island, but abundance and impact require close monitoring (Director of National Parks 2010; J Christian 2024, pers comm 11 January).

Madeira vine (Anredera cordifolia)

Madeira vine is becoming a significant threat on Norfolk Island in both public reserves and on private land. The species is a fleshy climber with stems that can climb high into the canopy, and it typically invades the margins of rainforests, smothering small trees and shrubs. The presence of underground and aerial tubers makes this species difficult to control.

Wild tobacco (Solanum mauritianum)

Introduced to Norfolk Island in about 1855, this is a fast-growing tree that can occupy habitats for rare, shade-intolerant species such as chaff tree (Achyranthes arborescens) and nettle tree (Boehmeria australis australis) (Sykes & Atkinson 1988). As wild tobacco prefers open areas it is generally considered to be less of a threat in forested national parks than shade-tolerant species such as red guava and African olive (Director of National Parks 2008). It is often found in parts
