Biodiversity of AlabamaState and National
Symbols

90. AL State Tree Longleaf pine
  • The bark is thick, reddish-brown, and scaly.
  • Needles are twisted and remarkably long, up to
    18 inches
  • Vast stands across the eastern U.S. have been
    dramatically reduced
  • Longleaf Pine is highly resistant to fire.
    Periodic natural wildfire selects for this
    species by killing other trees.

91. AL State Butterfly Eastern Tiger Swallowtail
  • Some of its common habitats include, woodlands,
    woodland openings, woodland edges, fields, open
    areas, rivers, creeks, roadsides, gardens, urban
    parks, and city yards.
  • Young caterpillars are brown and white, while
    older caterpillars are green, with two black,
    yellow, and blue eyespots on the thorax.
  • Named for pointed shape of wings, like the bird

92. AL State Insect Monarch Butterfly
  • Monarchs are especially noted for their lengthy
    migration throughout parts of North America
  • But no single individual makes the entire round
    trip, which lasts longer than one butterflys
    lifespan.
  • Female monarchs deposit eggs for the next
    generation during these migrations.
  • Bright orange and black pattern is warning
    coloration to keep predators from eating them
    they taste bad

93. AL State Freshwater Fish Largemouth Bass
  • The largemouth bass is a heavy-bodied fish with
    the upper jaw usually extending past the rear
    margin of the eye. The back is olive green to
    brown, and the greenish sides are marked with a
    broad black band composed of somewhat oval
    blotches connected by shorter blotches.
  • Largemouth bass occupy almost all aquatic
    habitats in Alabama.
  • The largemouth bass is the primary target species
    of most recreational and tournament bass anglers
    in North America.
  • Largemouth bass prey upon bluegills and redear
    sunfish in stocked ponds and upon shad, minnows,
    smaller sunfishes, crayfishes, and amphibians in
    natural habitats.

94. AL State Saltwater FishAtlantic Tarpon
  • Megalops atlanticus
  • Inhabits coastal waters, estuaries, and rivers.
  • Tarpons feed almost exclusively on schooling fish
    and occasionally crabs.
  • Important fish for sport fishing up to 350 lbs

95. AL State Amphibian Red Hills Salamander
(endangered)
  • Phaeognathus hubrichti
  • Entire global distribution confined to five
    Alabama counties in Red Hills
  • Not discovered until 1960s
  • Secretive, inhabits burrows on forested bluff and
    ravine slopes.
  • Eliminated from many formerly inhabited sites by
    habitat disturbance.

96. AL State Reptile Alabama Red-bellied Turtle
(endangered)
  • Pseudemys alabamensis
  • Restricted to extreme lower portion of Mobile Bay
    drainage in Mobile and Baldwin Counties.
  • Primarily a freshwater species, but may occur in
    moderately brackish water with abundant
    vegetation.

97. AL State BirdNorthern Flicker (or
Yellowhammer)
  • The name Yellow-hammer comes from a term that
    was applied to a company of young cavalry
    soldiers from Huntsville. They were called the

    yellow bits of cloth on the sleeves, collars, and
    coattails of their new uniforms.
  • Flickers are a type of woodpecker

98. AL State Game Bird Wild Turkey
  • Meleagris gallopavo
  • Males display to females by spreading feathers
    and strutting around polygamous (males mate with
    several females in a season)
  • Females are plainer, build ground nests
  • Omnivorous
  • Benjamin Franklin wanted this to be our national
    bird

11
AL State MammalAmerican Black Bear
  • Ursus americanus
  • Rare. Once found statewide, but now extirpated
    from all except an area just north of Mobile,
    where they still breed.
  • Transients from Georgia and Florida also
    occasionally enter the state.
  • Occupies woodland and swampland habitats.
  • Classic omnivores eat a variety of plant and
    animal materials, including some agricultural
    crops

100. National Symbol Bald Eagle
  • National symbol, found in Alabama
  • Preys on fish
  • Almost driven to extinction by effects of DDT
    (pesticide that got into food chain and caused
    birds egg shells to be fragile)
  • Success story! Not on endangered species list
