The central
slough area has soil made up of sandy loam or silt material and is covered
with water approximately four to six months of the year, during the
wet season. The lush plant life in the cypress slough absorbs pollutants
from the water while slowing the flow and allowing sediments to settle
out. This process cleans the water as it flows southwest through the
Slough and empties into the Estero Bay Aquatic Preserve.
The dense forest
canopy of the cypress slough community provides shade that helps to
modify temperature extremes, thereby slowing the evaporation of the
water.
Bromeliads,
orchids and other epiphytes have adapted to an aerial way of life where
the conditions of shade and fluctuating water levels vary, as they do
in the cypress slough .The
trees of the cypress slough also provide shelter and food for many Slough
residents.
