Back
Upper Lumaha‘i Valley is unique in that it is one of the last places in the state where a continuous canopy of lowland vegetation exists.  Unfortunately, a combination of pig and goat disturbance and the presence of Clidemia hirta has damaged much of the understory vegetation and ground cover.

The spore-dispersed Australian tree fern has invaded upper Lumaha‘i Valley and it is estimated that, without intervention, ATFs could compose about 40% of the overstory within ten years.
