THE EVERGLADES
- AN
ECOSYSTEM IN PERIL
Once a vast, free-flowing river of
grass, with sloughs, marshes, cypress swamps, lagoons and bays, the
Everglades was home to thousands
of species (both resident wildlife and migrating visitors). This
wetland ecosystem once covered 4,000 square miles and is now reduced
to half that size.
The waters in these
wetlands have been diverted, drained, dammed and
polluted. The consequences of this type of human intervention have
been dire. Water flowing through the ecosystem has been reduced by
approximately 70 percent, and Lake Okeechobee (the second largest
freshwater lake that is situated wholly in the U.S.) is seriously
threatened. Salt water has intruded farther inland where
slow-moving water from swamps once held it back. Fresh-water wells
have become salty. Functions once performed by the wetlands, such
as filtering and retaining water to maintain a healthy diverse
wetland environment for species, have been lost as the Everglades
has become polluted and shrunken in size. "A number of plants
and animals that live in south Florida and the Everglades are in
danger of becoming extinct because their habitat has been damaged,
reduced or eliminated."
Everglades Restoration Plan - the largest restoration plan on Earth!
The U.S.
is now planning to spend billions of dollars
to try and restore the intricate balance of the Florida Everglades
ecosystem. Comprehensive plans have been designed to
revitalize the ecosystem to a healthy and sustainable state that
will enable these wetlands to once again support vast numbers of
wildlife and nursery grounds for marine life, while maintaining
flood protection, and providing future fresh water supplies for the
people and farms of the south
Florida region. It is estimated the full project will take
20-30 years to restore the Everglades.
The Everglades
- Yesterday and Today
Looking back on the giant marsh of the past which encompassed
the greater part of southern Florida, to a time when daylight
was almost obscured by thousands of birds in flight, and great
numbers of unique and diverse species found food and shelter
provided by this huge ecosystem - we are now shocked and dismayed at
the deterioration that has occurred due to human expansion into this
natural wildlife habitat. This is the Everglades of today - an
eco-system in peril.
In order to try and
undo the detrimental effects humans have had on the Everglades, and
restore the wetlands as much as possible, we need to understand the
workings of the original system and incorporate the science and
technology of today into a comprehensive plan for the future.
The South Florida
Water Management District, working with other state and federal
agencies, has developed programs that focus on "sound management
based on strong science and data." Information and data is
provided on their website, including: Watershed Management,
Hydrology, Nutrients, Vegetation, Wildlife, and Restoration -
pertaining to the specifics of the Everglades, Florida Bay and the
Entire Ecosystem. Click into Long-Term Plan to learn about the

The Living
Everglades - One of Earth's great natural ecosystems
During wet seasons and dry seasons, the Everglades has functioned
like a living giant sponge - that expanded in the rainy season from
drinking in the waters, and shrinking again as it dispersed liquid
life support to a huge ecosystem full of plants and animals.
These marshy waters would move slowly over the southern Florida
peninsula on their way to the ocean, while unfolding liquid fingers
of life-giving waters east and west. Imagine the spongy soils
as living lungs that function on water rather than air. In and
out, in and out, this ancient natural cycle ebbed and flowed over a
very, very long time in Earth's history, allowing a great diversity
of species to flourish.
As more and more
people moved to Florida, the needs of humans took precedence over
the needs of wildlife and the natural environment. As human
development increased, the wetlands decreased, and the
magnificent natural process began losing its ability to provide life
support services to the once-massive numbers of wildlife; species
that not only inhabit the U.S., but migrate south and north from
pole to pole.
The Living
Everglades website is designed to provide citizens, scientists,
teachers, and students access to a vast amount of information and
data about the Florida Everglades. Maps, Topography, Info and
links to historical information, Geology, Habitats, Wildlife, Water
Resources, Weather, Links, FAQs, Search function, and a page of
links to glossaries. Take a virtual tour, query data.
Educational resources are provided for teachers and students, with
curriculum, lesson plans, fun activities, The Living Everglades
for K-12, and The Everglades - An American Treasure.

What we can do
to help the Everglades - Information is provided on this
site for residents of Florida, and for the many people who visit and
travel to Florida, regarding protecting and conserving precious
water resources. Learn what activities to avoid that may cause
environmental contamination. There are things we do that may
seem harmless, but they may set in motion other actions that cause
pollutants to be carried to water resources. These helpful
tips are good to practice no matter where we live or visit.
Water is a shared resource - and we all should share in protecting
it.
