Ardisia elliptica (invasive exotic) demography in Florida: light and moisture dependence
Ardisia elliptica 1998-2001
The demography of five populations of A. elliptica in its invasive range in extreme southern Florida was studied. The study plots were chosen in Everglades National Park in a disturbed area to represent populations growing in a range of moisture and light environments to quantify the spatial
and temporal variation in population dynamics of
over a three transition years, starting in 1998 and endint in 2001. We sought to identify the factors that are contributing to its demographic success. Randomization techniques were used to quantify spatial and temporal variation.

Everglades National Park, Florida. Areas nearby to Royal Palm Research Station, including some in and others adjacent to a site known as "hole in the donut". Two of the populations were located in relatively undisturbed hardwood forests locally known as hammocks, which are composed of broad-leaved, tropical trees. The other three populations occurred in disturbed habitats that were composed of a canopy of S. terebinthifolius and an understory of A. elliptica. Although the vegetation is currently
similar among these three sites, the sites were quite
distinct prior to human disturbance, one had been a
wetland prairie, the second had been a rockland pine forest, while the third had been a transitional forest between rockland and wetland.

Sampling Area And Frequency:
The five plots were studied from 1998-2001 except for one study plot that was accidentally herbicided by the Park managers during the summer of 2000.
All plants within delineated study plots were tagged and censused.
