Angiopteris evecta establishes dense stands that dramatically alter ecosystems by displacing and outshading native species. It has established abundant, invasive populations in Hawaii, Costa Rica, and Jamaica that threaten native plants as well as general biodiversity and may pose a serious threat to native plant diversity in the tropics. Angiopsteris evecta is thought especially problematic on islands that house many of endemics, have patchy, relatively disturbed forests (Christenhusz & Toivonen, 2008; Christenhusz, pers. comm., 2010). Nevertheless in some areas of its native range the species is rare and does not pose any threat.
Location Specific Impacts:
Threat to endangered species: It may pose a threat to the native tree-ferns and other native flora.
Hawaii (United States (USA))
Reduction in native biodiversity: Angiopteris evecta form dense stands that displace and shade out native flora of Hawaii, dramatically altering ecosystems (Christenhusz & Toivonen, 2008).
