Description
This diverse ecological site has a very tall (80 to 100 feet or 25 to 30 meters) tree canopy. Ground cover is dense, epiphytes are sparse to moderately abundant, and climbing vines are common (Forestry Program, Division of Community and Natural Resources, 2010; Sene, 2020; Webb and Fa`aumu, 1999; Whistler, 2002).
Dominant plant species
nephelium (Nephelium), tree
planchonella (Planchonella), tree
alphitonia (Alphitonia), tree
Hawai'I birdnest fern (Asplenium nidus), grass
musk fern (Phymatosorus grossus), grass
pepper (Piper), grass
Submodel
Description
This state consists of one community phase that has been cleared of natural vegetation and planted with coconut palms (Cocos nucifera).
Dominant plant species
coconut palm (Cocos nucifera), tree
Submodel
Description
This state consists of one community phase dominated by a variable mixture of native and introduced small trees, shrubs, vines, forbs, and grasses that thrive in sunny environments. Remnant coconut palms are likely present.
Dominant plant species
coconut palm (Cocos nucifera), tree
white leadtree (Leucaena leucocephala), tree
giant false sensitive plant (Mimosa diplotricha), shrub
merremia (Merremia peltata), grass
romerillo (Bidens alba), grass
Submodel
Transition T1A
Removal of native vegetation and planting coconut palms (Cocos nucifera).
Mechanism
The Reference State (1) transitions to the Coconut Plantation State (2) by removal of native vegetation and planting coconut palms (Cocos nucifera).
Mechanism
The Reference State (1) transitions to the Cleared and Abandoned State (3) if cleared and abandoned. This allows heliophytes, both native and introduced, to temporarily cover the understory.
Mechanism
The Coconut Plantation State (2) transitions to the Cleared and Abandoned State (3) if cleared and abandoned. This allows heliophytes, both native and introduced, to temporarily cover the understory.
Mechanism
The Cleared and Abandoned State (3) may be restored to the Reference State (1). The intensity of active restoration measures will be determined by the presence or lack of nearby native forest or, at least, some native trees as well as the density and species mix of grasses, vines, shrubs, and trees present on the site, especially if many competitive introduced species are present.
