State 3, Plant Community 3, Alien Forest plant community.

State 4 –Alien Weedy Meadow

This state consists of one plant community consisting primarily of weedy shrubs. Weedy grasses and forbs dominate between shrub patches. Alien tree species are present and will attain dominance if fire does not set them back. The array of species is diverse. Large amounts of fine fuels present a fire danger in dry periods.

Pathways from this state

To Plant Community 3, Alien Forest, via “F”:

F = absence of fire.

The ubiquitous presence of fast-growing tree species such as albizia, strawberry guava, and octopus tree will convert this plant community to Alien Forest if fire does not occur for a period of years.

To Plant Community 5, Pasture, via “G&H”:

G = land clearing; H = pasture establishment.

Alien Weedy Meadow can be converted to Grassland by land clearing and planting of desirable forage species.

tate 4, Plant Community 4, Alien Weedy Meadow plant community.



State 5 – Pasture

This state consists of one plant community that arises from clearing forests and planting introduced pasture grasses. Continuous grazing weakens desired species relative to undesired species, resulting in weedy pastures with reduced capacity to produce forage.

Pathways from this state

To State 4, Alien Weedy Meadow, via “I”:

I = abandonment.

Pasture degrades to Alien Weedy Meadow abandonment, leading to rapid replacement of the pasture species by weedy grasses, forbs, shrubs, and small trees.
