Transition T1A
State 1, the Reference State, transitions to State 2, Weed-Invaded State, by invasion of introduced species. Disturbance by feral deer, goats, and pigs will hasten this process, as will landslides and hurricanes.
More details -
Restoration pathway R2A
Restoration of State 2 Weed-Invaded State to State 1 Reference State or a facsimile of it may be possible by installing ungulate-proof fence, removing all ungulates, removing introduced plant species, and replanting native species when needed. Long term weed management and fence maintenance would be necessary.

Target ecosystem state
Select a state
Description
This state is comprised of one community phase. With disturbance from hurricanes, landslides, or introduced mammals, invasive plants invade the site and native plant species decline in abundance. Invasive plants may invade the site without other disturbances, but the process is much slower.
Submodel
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, goats, and deer, will facilitate the transition to this state.
