Ecological Risk Screening Summary - Umbrella Sedge (Cyperus albostriatus) - Uncertain Risk

Cyperus albostriatus, Umbrella Sedge, is a plant that is native to southern Africa. C. albostriatus is cultivated as an ornamental plant and prefers swampy places, shores, and forests. It can spread
through seeds and underground stems. The History of Invasiveness for C. albostriatus is classified as Data Deficient because although it has been documented as established outside of its
native range in the United States, Oceania, and Europe, no information was available on impacts of its introduction. The climate match analysis for the contiguous United States indicates
establishment concern for this species. The climate match was highest in Florida and Texas, where the species is already present, and was also medium to high in most other areas of the
contiguous United States. The northern Pacific Coast had areas of low match. The Certainty of Assessment for this ERSS is classified as Low due to a lack of information from which to assess
impacts of the introductions. The Overall Risk Assessment Category for C. albostriatus in the contiguous United States is Uncertain.
