Doryopteris angelica is a fern found in diverse mesic forest at 800-890 m elevation, only on the island of Kauai, Hawaii.
It is very rare and localized, and only three populations that are known to exist in the wild: one in Kuia Valley with around 20 individuals, one in Makaha Valley with around 10 individuals, and one in Awaawapuhi with only a few individuals.
The biggest threats to this extremely rare fern are the same as for many other endemic Hawaiian plants and include feral pigs and deer and competition from invasive alien plant species.
