Description
This state is comprised of one community phase. We observed no examples of this community phase that were not dominated by introduced species. It consists of flat areas of soils that are saturated to the surface or shallowly flooded or ponded. These areas are surrounded by medium-stature forest vegetation described for ecological site F159AY504. Vegetation is sedges, rushes, and grasses. Small ohia lehua trees, ohelo shrubs, and uluhe fern grow on fallen logs and old stumps within the bogs.

State 2
Weed-Invaded State
Weed-Invaded State
Description
This state is comprised of one community phase. It comes into being by gradual invasion of introduced species. Disturbance of the soil and direct damage to native plants by introduced ungulates, particularly pigs and cattle, will likely facilitate the transition to this state.
Submodel
Mechanism
State 1, the Reference State, transitions to State 2, Weed-Invaded State, by invasion of introduced grass, sedge, rush, and forb species. Disturbance by feral cattle and pigs may hasten this process.
Mechanism
Restoration of State 2 Weed-Invaded State to State 1 Reference State or a facsimile of it may be possible by installing pig-proof fence, removing all ungulates, removal of introduced species by hand weeding, and replanting native species when needed. Long term weed management and fence maintenance would be necessary. We are aware of no attempts at this restoration. Because we observed no undisturbed, weed-free examples of this ecological site, attempts at restoration would be speculative as to species composition.
