Nā Pōhaku o Hauwahine Restoration Project

Family THELYPTERIDACEAE

Cyclosorus interruptus (Willd.) C. Ito
Neke, swamp cyclosorus; indigenous
NOTES: Grows naturally in marsh nearby, and fould in limited spots within the pond restoration area at Nā Pōhaku o Hauwahine. Early efforts at moving plants around the ponds failed. However, in the last 5 years, this fern has been spreading into areas of the marsh previously over-run by Califiornia grass, especially opposite Nā Pōhaku and has now (2018) become the dominant plant in this middle part of the marsh.

Family NEPHROLEPIDACEAE

|
Nephrolepis cordifolia (L.) C. Presl.
sword fern; indigenous
NOTES: Reproduction vegetative. Some areas of site support this fern, although used to die-back in the dry season. The situation seems to have changed, and this fern now covers many areas on the north slope and is spreading. [mesic, forest openings, modest shade]
Population: ~45 (9/15) / TNTC (5/18)

MISC. FERNS and FERN ALLIES
|
|
The following species have been planted or observed, but are not counted as successfully established:
Psilotum nudum / moa — Appearing naturally in 2010 on rocks near water catchment; since disappeared
Pteris cretica / ‘ōali — One planted in 2011; since disappeared
In general, ferns are only rarely observed growing naturally in this area. Single individuals (as spontaneous introductions) of Nephrolepis multiflora (Nat), Sphenomeris chinensis (Ind), and Adiantum macrophyllum (Orn) have been noted. However, the area appears to be wetter now than in previous decades, so attempts to introduce native ferns would seem warranted.
