and brushland, and exotic plant communities. The disturbed habitat types cover

69.5% of the total area with the vast majority of disturbed cover being

sugarcane. Within Compartment A, 79% of the area is classified as disturbed

with sugarcane also being the dominant cover.

2.9.3.5 Urban and Extractive Communities

The urban and extractive cover communities encompass 14% of the EAA land

area and consist of bare soil/clearcut areas (12%), low impact urban land (1%),

high impact urban land (less than 1%), and extractive areas (substantially less

than 1%). Most of the urban and extractive lands are concentrated around the

Belle Glade area. Bare soil/clearcut areas are associated with a recent timber

cutting operation, natural bare soils, and bare soil exposed due to clearing

vegetation. Low impact urban areas consist of either vegetated or non vegetated

lands within areas such as lawns, golf courses, road shoulders, and grassy areas

surrounding development. High impact urban areas are non vegetated sites

such as buildings, roads, and parking lots. Extractive cover areas consist of

surface mining operations such as limestone quarries, phosphate mines, and

sand pits as well as the associated industrial complexes.

Within Compartment A, 21% of the land is in the urban and extractive category,

with the majority being in the bare soils/clearcut subcategory (20%). The

remaining 1% of this category is divided between the low and high urban impact

land, with no extractive land designated.

2.9.4 Water Conservation Areas 2 and 3

Almost all of the WCAs are grass-dominated wetlands interspersed with tree

islands (hammocks) and willow strands. Tree islands are a unique feature of the

Everglades ecosystem. Tropical hardwoods are found on some of the relatively

unaltered tree islands in the southern portion of the area.

The basin marsh community type develops in broad, shallow to intermediate

depth basins with peat substrate. The dominant plant cover is sawgrass and/or

buttonbush and/or mixed emergents. In general, there are three recognizable

types of basin wetland communities present in the WCAs:

1. Sawgrass marsh composed of sawgrass with cattail, maidencane,

arrowhead, pickerelweed, willow, buttonbush, wax myrtle, and saltbush.

2. Wet prairie, composed of beak rush, spike rush, maidencane, string lily,

and white water lily.

3. Aquatic slough composed of white water lily, floating heart, spatterdock,

bacopa, and bladderwort.
