Exploration 1Wading Into Our Wetlands
What exactly is a wetland? This is not an easy question to answer becausethere are many types of wetlands. The scientific and legal definitions of wetlandsare often different. Even our elected officials had difficulty defining wetlandsin 1984, when the Florida Legislature passed a Wetlands Protection Act. Inorder to help people define wetlands, the officials decided to use a plant listcontaining the kinds of plants usually found in wetlands. We are very fortunateto have a lot of wetlands in Florida. In fact, Florida has the third largest wetlandacreage in the United States. Knowing that we have many wetlands in our area isimportant, but what really is a wetland? Put on your wading boots and letsfind out!
The term wetlands includes a wide variety ofaquatic habitats. Swamps,
marshes, wet meadows, bogs and fens these are all names for ecosystemsknown as wetlands. In general, to be considered a wetland, a region must havewet soils or be covered by a shallow layer of water for at least part of the year.Some wetlands are always covered with water. Other wetlands may be floodedfor only a short period of time. Try to think of at least one wetland area that islocated near your home.
Wetlands are natural reservoirs that hold water. They are characterizedby water and by soil that is saturated, or hydric. Because all wetlands havewater-soaked areas at some time, they attract a wide variety of plants andanimals especially suited for wet environments.
Most wetland experts look for the following characteristicswhen deciding if an area is really a wetland:
The area is flooded or has saturated soils for certainperiods of time during the year.
The area contains special plants and trees that are commonlyfound in wetland areas and thrive in water or waterlogged soil.
The area has unique soils that are different from soils found in other areas.
Wetlands may be divided into different categories based on featuresthey have in common. The two main types of wetlands are saltwater wetlands
andfreshwater wetlands. Saltwater and freshwater wetlands may befurther divided into more specific categories. For example,a swamp contains trees and shrubs, while a marsh isfilled with grasses and soft-stemmed plants. The kinds oftrees, plants and animals that exist in wetland areas may alsovary. Explorations 2 and 3 describe several types of wetlands insouthwest Florida.

Exploring WetlandsDid you know that there is a
wonderful place to experience naturalFlorida within the boundaries of the
Southwest Florida Water ManagementDistrict? It is called the Green Swamp.The area includes several types offreshwater wetlands. The GreenSwamp spreads across approximately870 square miles and includes partsof Pasco, Polk, Lake, Hernando andSumter counties. Its amazing thatfour major rivers have origins in theGreen Swamp. The Hillsborough,Peace, Withlacoochee and Ocklawaharivers all begin here.
On a visit to the Green Swamp, youcan explore several kinds of wetlands.You will have the opportunity toidentify special plants, shrubs andtrees that grow in the different areas.In sections where water covers theground for most of the year, only a fewspecies of trees are able to survive.The cypress tree is an example of one
species that is able to grow in water.These spectacular trees are easilyfound in cypress wetlands. By lookingvery closely at the soil in a wetlandarea, you will find that it is different
from soils in other surface land areas.This is because the soil in wetlands ismade up of peat or muck deposits thathave built up from the surroundingwet environment.
During your visit, dont forget toobserve the abundance ofwildlifethat live and breed here. If you listenclosely, you may even be able to heara symphony made up of a full rangeof sounds that exist in nature. Take aguided tour through the GreenSwamp by visiting the Green SwampInteractive web site atWaterMatters.org/greenswamp/.
For additional information aboutother natural sites in west-centralFlorida, or directions to the GreenSwamp Wilderness Preserve, call theCommunications Department of theSouthwest Florida Water ManagementDistrict at 1-800-423-1476, ext. 4757.

Exploration 2Searching Our Saltwater Wetlands
As you learned earlier, wetlands can be divided into two main categories:saltwater wetlands and freshwater wetlands. During this exploration, you willlearn about saltwater wetlands found along the edges of estuaries such as TampaBay, Charlotte Harbor and Sarasota Bay. Estuaries are areas where fresh waterfrom inland sources mixes with salt water from the Gulf of Mexico or the ocean.These wetlands are known as saltwater wetlands because they contain salt. Thetwo kinds of saltwater wetlands that we are going to examine more closely arecoastal saltwater marshes and mangrove swamps. Lets find out more aboutthem now.
Coastal SaltwaterMarsh
The coastal saltwater marsh is,as it says in its name, a saltwaterwetland. Coastal marshes arenonforested wetlandsthat form in areas oflow elevation alongshores of Floridasgulf coast wherethe ocean meetsthe land.
Coastalsaltwater marshesare among theworlds most productivehabitats for fish andwildlife. Many varieties ofmarine life can be found here, as well
as nurseries for fish, shellfish, crabsand shrimp. The fresh water mixeswith salt water and makes it a livableenvironment for these young animals.Did you know that most of Floridascommercial seafood harvest is madeup of fish and shellfish that dependon these coastal wetlands?
Coastal marshes also provide habitatfor birds, small mammals and turtles.
Many kinds of plants grow insaltwater marshes. On a visit to asaltwater marsh, you will most likely
see black needlerush, which isa gray, grassy plant that
grows well in high,marshy areas. You willalso see cord grass,
which is the mostcommon speciesof plant found ina coastal marsh.Cord grass grows
from two to six feettall and is
typically foundfrom sea level to
four feet above sea level. Its
intricate root system helpskeep the soil anchored as thetides move in and out.

Mangrove SwampsOn a trip along one of Floridas
many bays, you are bound to comeacross a forest ofmangroves, ora mangrove swamp. Mangroves areunique because of their ability to growwell in salty environments. Did youknow that some mangroves actuallyseparate fresh water from seawater?Some mangroves can even give offexcess salt through their leaves, whileothers are able to block outthe intake of salt attheir roots.
There are
three kinds ofmangroves thatmake up theapproximately500,000 acresof mangroveforests that existwithin our state.The red mangrove isthe most common and maybe found growing near water. If you
have ever seen these red mangroves,you already know that they often looklike they are standing or walking.
This is because their roots stick outwell above the surface. This featurehas earned them the title of walkingtrees. Another type of mangroveis the black mangrove. It is easily
identified by numerous fingerlikeroots that wrap around the base of thetree trunk. The third type of mangroveis the white mangrove. Unlike the redor black mangrove, you wont see thewhite mangroves roots at the surface.
Mangroves play animportant role in saltwater
forested wetlands. Theirroots and branches
provide homes formany waterfowl,such as brownpelicans and roseatespoonbills. They alsoserve as nurseries
for a variety of fish,crustaceans and shellfish,
which, in turn, supplyfood to many marine species,
including snook, snapper, tarpon,
jack and sheepshead.
Writing AboutWetlands1. Describe how mangroves are
able to survive in a salty
environment.2. List several reasons why
mangroves are important forkeeping saltwater forestedwetlands healthy.
Wetlands Wit1. Name several young animals
that may be found in the
nursery environment of anestuary.
2. Which kind of mangrove isknown as the walking tree?Why?

Exploration 3Finding Out About
Our Freshwater WetlandsNow that you have searched the saltwater wetlands, lets find out about
freshwater wetlands. These wetlands are known as freshwater wetlands becausethey contain fresh water. The freshwater, forested wetlands we will exploreinclude cypress swamps, hardwood swamps and hydric hammocks. In addition,we will look at freshwater marshes and wet prairies, which are examplesof freshwater, nonforested wetlands. Lets begin our exploration of thesefreshwater wetlands now.
Cypress SwampsCypress swamps are known for
their mysterious appearance. Baldand pond cypress trees with mossdrapes and gnarled roots may befound throughout the quiet, darkwaters of this eerie swamp. The poorlydrained soil consists of finely texturedorganic materials. While exploringthis area, you will be surrounded bymany cypress knees or stumps of dead
cypress trees. Epiphytes, such asspanish moss and other air plants, canbe found here. Other trees that livehere are the black gum and red maple.The American alligator makes thiswetland its home, along with raccoons,river otters, frogs, Florida snappingturtles, snakes and fish. The cypressswamps are usually flooded for four toeight months each year.

Hardwood SwampsHardwood swamps are forested
wetlands filled with all shapes andsizes of hardwood trees. Standingnear or in the glassy tea-coloredwaters are black gum, red maple,water ash, laurel oak, water elm,cypress and willow trees. Theseswamps often border rivers, streamsand lakes. It is a place where you can
observe wood ducks drifting along onthe water and gray squirrels chatteringin the trees. Hardwood swampsare submerged or saturated part ofthe year due to seasonal periods offlooding.
Hydric HammocksHydric hammocks are located
between river swamps and at the edgeof flatwoods. These forested wetlandsare filled with a mixture of broad-leafevergreens and deciduous treesthat shed their leaves every year.The area may remind you of a lushtropical paradise because it is filledwith cabbage palms, laurel oaks and
climbing vines. In addition to blueviolets, longspur and green fly orchids,many other beautiful flowers growwild here. Animals such as the grayfox, striped skunk and bobcat may beseen roaming the area. Although theseareas are seldom flooded, the soils aresaturated most of the year.

Freshwater MarshesA freshwater marsh is a wetland
area that resembles a pond, exceptthat it is covered with water plants andother kinds of vegetation. Althoughyou wont see any trees here, youwill find many woody plants, grasses,sedges, rushes and other soft-stemmed plants. The marsh providesfood, protection and breeding sites
for many animals, including alligators,turtles, various water birds, otters andraccoons.
Wet PrairiesWet prairies are large fields
of grasses, sedges, rushes andwildflowers. They are also known aswet meadows. These areas are floodedfor short periods of time and usuallystay saturated the rest of the year.Garter snakes, frogs, ducks, rabbits anddeer are just a few of the animals youmight see on a visit to this area.
Wetlands Wit1. Which swamp is often found
along rivers, streams andlakes?
2. Which wetland lookslike a pond?
Writing AboutWetlands1. Cypress swamps are often
described as mysterious orscary. Imagine that you areexploring a cypress swamp.Write a paragraph thatdescribes your thoughts and
feelings about being there.2. Compare the features of a wet
prairie and a cypress swamp.Make a list of the things youwould include in a picture ofeach wetland.

Exploration 4Discovering What Wetlands Do
Until recently, most people thought of wetlands as dirty, smelly, unpleasantplaces filled with mosquitoes, pests and scary creatures. Wetlands used tobe called wastelands and were drained so the land could be used for homes,businesses and farming. Now we realize that they play a very important rolein helping to keep our environment clean and healthy. Fortunately for us, lawshave been enacted to save and protect our precious wetlands.
Study the following list to discover what wetlands do for us in southwestFlorida. When you have finished, try to think of additional ways wetlands areimportant to us and help our environment.
Wetlands help improve our waterquality.
Wetlands are natural cleaningsystems. They have often been callednatures kidneys because they helpclean out the pollutants that movethrough them. They purify and filtercontaminants from agriculturalactivities and from water that drainsor flows off the surface of the land.
The plants in a wetland help cleanwater by trapping solids and absorbingthem in their roots. Bacteria and othermicroorganisms improve the quality ofwater by eating and digesting organicwastes.
Wetlands help protect us fromfloods.
Wetlands act as giant sponges.
They can absorb heavy rainfalland release the water veryslowly so that businesses and
housing developmentslocated nearby wontbe flooded. Wetlandslocated along the coastserve as natural barriers
that can reduce damage from stormsurges.
Wetlands help store water.
Wetlands are important storageareas that collect rainwater. Some ofthe water soaks into the ground to refillthe aquifer. Some is gradually releasedeither back to the atmosphere or toother surface bodies of water.
Wetlands help support a variety offish, waterfowl and other wildlife.
Wetlands are habitat for manyanimals and birds that cannot nest,breed or live anywhere else. Did youknow that 22 species of wading birdsdepend on Floridas wetlands? It isalso a fact that nearly two-thirds ofour marine fish and shellfish rely on
saltwater wetlands for their survival.White-tailed deer, bobcats, gray foxes,black bears, panthers and other largemammals use wetlands for theirhabitat. Other animals that can beobserved in wetlands include raccoons,skunks and river otters.

Wetlands help serve as nurseryareas.
Wetlands are nursery areas thatprovide food and shelter for a wide
variety of fish, birds, reptiles andmammals. Nutrients deposited inwetlands are the building blocksof food chains that are part ofthe complex network of feedingrelationships in an environment.
Wetlands help stabilize our coastalshorelines.
Wetlands located along the coast
provide a barrier and buffer zonebetween salt water and fresh water.These vegetation-filled brackish waterareas help prevent coastal erosion bytrapping and stabilizing sedimentsthrough their roots.
Wetlands help provide recreationalactivities.
Many recreational activities takeplace in and around wetlands. People
use wetlands for outdoor experiencessuch as hiking, fishing, boating, birdwatching and photography.
Wetlands provide habitat forthreatened and endangeredspecies.
Wetlands provide habitat crucialto the survival of nearly one-third ofthe plant and animal species included
on a federal list of endangeredspecies. Endangered species thatdepend on Floridas wetlands tosurvive include the wood stork,black bear, limpkins, sandhill crane,southern bald eagle, osprey, little blueheron, orchid and pleat-leaf.
Wetlands Wit1. Why are wetlands often
called natures kidneys?2. Name two endangered
species that dependon wetlands for theirsurvival.
Writing AboutWetlands1. Select two ways that
wetlands help ourenvironment and explainwhy they are important.
2. Create a list of five true orfalse statements about whatwetlands do, then give thequiz to a classmate.

Exploring Our Wonderful Wetlands
Wetland MetaphorsMany functions of wetlands can be explored through the use ofmetaphors. A metaphoris a figure of speech in which a word or phrase meaning one kind of object or idea is usedin place of another to create a comparison between them. In other words, a metaphorrepresents a concept or idea through another concept or idea. Saying Pauls brain is apowerful computer is using a metaphor. Pauls brain isnt really a computer, but it is beingcompared to a computer to make the point that he is very smart. Other examples include
Books are windows of thought or The lion is king of the jungle.
Directions: Examine the following pictures. How could each be a metaphor for awetland? Write your answers in the spaces provided.Example

Exploration 5Becoming Protectors of Our
WetlandsIt is very unfortunate that we have already lost many of our valuable wetland
resources, which can never be replaced. In the United States, between the 1780sand mid-1980s, more than 50 percent of wetlands became dry, were altered ordestroyed. Of the 215 million acres of wetlands, only about 100 million acresremain.
Most wetlands in Florida were lost before the 1970s. As people moved intothe state, wetlands were drained and filled with dirt. These areas were developedfor homes, businesses, agriculture, mining and other uses. As the wetlandsdisappeared, so did the water. The existence of wildlife declined. The amount
and quality of fresh water also began to decrease. Fortunately, people began tochange their attitudes about the value of wetlands. Florida has become a leaderin reducing loss of wetlands, and the state Legislature has decided that the bestway to protect our precious wetlands is to acquire land or to regulate its use.
Protecting OurWetlands
Our federal and stategovernments have taken steps topreserve wetlands through protectionprograms. In addition, the Southwest
Florida Water ManagementDistrict works hard
to protect ourwetlands. Laws areenforced to restrictdredging and fillingof wetlands, limit
uses of wetlands
and minimize impacts caused bygrowth and development. Theprotection and purchase of wetlandswill help to save them for futuregenerations.
But there is still a lot of work to do.Important research is conducted eachyear to learn more about wetlandsand how to improve our ways ofprotecting, restoring and managingthem. Everyone must work togetherto protect our wetlands. That includesgovernment, builders, farmers,environmental groups, scientists
and YOU!
