When most people think of Louisiana, they think swamps.  They wouldn't be wrong but along with the famous swamp lands of this coastal state, there are rare prairie habitats, rolling hills, pine forests and spectacular beaches. 
  Perhaps the most iconic tree of Louisiana is the baldcypress.  Also the official State Tree, baldcypress trees are found in wetlands of all types and are an important component of the forests.  Those venturing near the water for world class fishing or hoping for a crawfish boil later, will undoubtedly

pass by some of these native giants.  Southern magnolias are also common throughout
Louisiana, so much so that their large white flowers are the State Flower.  The rivers,
streams, lakes, bogs, and swamps give rise to diverse bottomland forests.  Covering about
half the state, timber is one of the leading industries of Louisiana and is the number one crop. 
   The landscape of Louisiana has much to offer the nature lover.  The adventurous type may
want to explore the the Atchafalaya Basin, which is the nationís largest river swamp.  Over
550,000 acres in size, the basin is actually larger than the Florida Everglades and contains
some of North America's most important cypress-tupelo swamps, bottomland forests, lakes
and waterways.  Louisiana also offers the chance to see other rare or endangered
ecosystems such as coastal and calcareous prairies and hillside seepage bogs. 
   With such habitat diversity and plentiful bodies of water, Louisiana is also a mecca for bird
watchers.  In fact, John James Audubon spent much of his time studying birds here. 
Hundreds of native and migratory species of sea birds, waterfowl, woodpeckers, hawks, and
many more can be viewed.  Agricultural and urban development has had a negative impact on
the bird populations as well as the forests.  Many of the species are now endangered or
threatened due to habitat loss.  There are 23 species of trees listed in Louisiana with element
ranking between S1 and S3, meaning rare or imperiled, and a few ecosystems listed as G1-
globally imperiled.

One of the few deciduous conifer species in the world, Taxodium distichum, or baldcypress, was made the State Tree of Louisiana in 1963.

may reach 100 to 130 feet in height.  A long lived tree species, it is not uncommon to
find individuals over 500 years old in old growth forests.  In the spring, before the new
leaves begin to bud, green 'flowers' bloom near twig tips, hanging in a tassel like
structure.  Soon after, the small, alternate and yellowish green linear leaves appear.
   Baldcypress are essential to southeastern wetland areas.  They help reduce damage
from flooding, assist with riverbank erosion control, and remove pollutants and
sediments from the water.

especially vulnerable to extirpation.

• S2 = imperiled in Louisiana because of rarity (6 to 20 known

• S3 = rare and local throughout the state or found locally (even abundantly at some of its locations) in a restricted region of the state, 
or because of other factors making it vulnerable to extirpation (21 to 100 known extant populations)

• S4 = apparently secure in Louisiana with many occurrences (100 to 1000 known extant populations)

• S5 = demonstrably secure in Louisiana (1000+ known extant populations)(B or N may be used as qualifier of numeric ranks and
indicating whether the occurrence is breeding or nonbreeding)

• SA = accidental in Louisiana, including species (usually birds or butterflies) recorded once or twice or only at great intervals
hundreds or even thousands of miles outside their usual range

• SH = of historical occurrence in Louisiana, but no recent records verified within the last 20 years; formerly part of the established
biota, possibly still persisting

• SR = reported from Louisiana, but without conclusive evidence to accept or reject the report

• SU = possibly in peril in Louisiana, but status uncertain; need more information

• SX = believed to be extirpated from Louisiana

• SZ = transient species in which no specific consistent area of occurrence is identifiable

Protected Status:

Endangered = Taking or harassment of these species is a violation of state and federal laws.
Threatened = Taking or harassment of these species is a violation of state and federal laws.
Threatened/Endangered = Taking or harassment of these species is a violation of state and federal laws.

Found across the state along
swamps, bayous, lakes, and
marshes, baldcypress are easily
identifiable by their buttressed
trunks, knobby knees, and
aptitude for growing with their
bases submerged.  Along the
Louisiana-Texas border on Caddo
Lake, grows the largest
baldcypress forest remaining in
the world. The forest, half in
Louisiana and half in Texas, is
internationally protected and
houses some of the oldest bald-
cypress trees in North America.
   The large trunks can grow 3 to 6
feet in diameter and mature trees
