Rumex oblongifolius (bluntleaf dock; bitter dock)

Synonyms: Acetosa oblongifolia

Invasive Species

Broad-leaved dock (Rumex obtusifolius) is a problematic weed throughout its native and introduced range. It invades a wide variety of habitats in the Sub-Antarctic region including areas dominated by native plant species. It is also a major problem in pastures. Current management strategies include chemical and mechanical control, although studies investigating biological control agents are ongoing.
