Endangered species

  1. 1. I GREW UP IN THE FLORIDA KEYS, I’VE GROWN ATTACHED TO THE OCEANAND ALL SPECIES INHABITING IT. THE GREAT HAMMERHEAD IS VERYMAJESTIC AND HAS SHOWN A 90% DECLINE IN THE ATLANTIC OCEAN.THEY ARE COMMONLY CAUGHT AS BYCATCH. ITS CURRENT STATUS ISENDANGERED WORLDWIDE.
  2. 2. AS A LIFELONG GAINESVILLE RESIDENT, I HAVE SPENT A LOT OF TIME INTHE SANTA FE RIVER. THE SANTA FE CAVE CRAYFISH IS BEING NEGATIVELYIMPACTED BY POLLUTION FROM MINING, GROUNDWATER ABSTRACTION,AND THE USE OF HERBICIDES AND PESTICIDES IN SURROUNDING AREAS.
  3. 3. AN ENDANGERED SPECIES NATIVE TO THE SOUTHEASTERN REGION OFTHE UNITED STATES IS THE SPOTTED TURTLE. OVER THE PAST TWENTY-FIVE YEARS, ITS POPULATION HAS DECREASED BY 50%. MUCH OF THEDECLINE HAS BEEN A RESULT OF HABITAT LOSS.
  4. 4. CARS ON U.S. 1 ARE HITTING DEER KILLING ABOUT 30 TO 40 DEER AYEAR. THE DEER HAVE ALSO LOST THEIR FEAR OF HUMANS. THE KEYDEER PROTECTION ALLIANCE IS AN ORGANIZATION HELPING TO SAVE THEKEY DEER.
  5. 5. THE OKALOOSA DARTER IS A FISH FOUND IN FRESH WATER STREAMS INNORTHWEST FLORIDA. THANKS TO LARGE HABITAT IMPROVEMENTS BYTHE JACKSON GUARD OF EGLIN AIR FORCE BASE, THE OKALOOSADARTER’S POPULATION DECREASES HAVE SLOWED, AND THE FISH’SSTATUS WAS CHANGED FROM “ENDANGERED” TO “THREATENED” IN 2011
  6. 6. THE FLORIDA SCRUB LIZARD, IS CURRENTLY LISTED AS “NEARTHREATENED,” ACCORDING TO THE RED LIST OF ENDANGERED SPECIES. INAMED ONE MARTY, AND KEPT IT IN AN OLD AQUARIUM FOR ABOUT AWEEK, KEEPING IT AS A PET, AND STUDYING THE LIZARD.
  7. 7. THERE ARE ONLY ABOUT 2,500 OF THE CHEROKEE CLUBTAIL STILL INEXISTENCE. THE NATURAL HABITAT OF THIS DRAGONFLY IS RIVERS,WHICH I LOVE TO STUDY
  8. 8. GOPHER WOOD IS CRITICALLY ENDANGERED BECAUSE THERE HAS BEENA 98% DECLINE IN MATURE INDIVIDUALS WITHIN THE LAST THREEGENERATIONS.
  9. 9. I CHOSE LEATHER BACK TURTLES BECAUSE THEY HAVE BEENENDANGERED SINCE 1986 AND ARE NOW CONSIDERED CRITICALLYENDANGERED. VERY FEW LEATHERBACKS MAKE IT TO ADULTHOOD DUETO ITS HIGH PREDATION RATE AS YOUNG; THIS MAKES IT INCREASINGLYHARD TO PERVERSE THEM IN NUMBERS
  10. 10. I CHOSE THE FLORIDA PERFORATE REINDEER LICHEN (CLADONIAPERFORATA). I CHOSE THIS SPECIES FOR SPECIAL ATTENTION BECAUSE IHADN’T HEARD OF IT BEFORE THIS ASSIGNMENT. CONSERVING THELICHEN IS IMPORTANT FOR FLORIDA’S ECOSYSTEM AND ITS RAPIDDISAPPEARANCE WARRANTS ATTENTION.
  11. 11. THE PRIMARY REASON I CHOSE THE GREEN TURTLE OR CHELONIA MYDASIS DUE TO THE FACT THAT I WAS SHOCKED TO SEE IT LABELEDENDANGERED.
  12. 12. THE FLORIDA PANTHER IS A MAJESTIC MAMMAL. DUE TO OVER HUNTINGAND ILLEGAL POACHING, THE POPULATION OF PANTHERS IN THE STATEDWINDLED TO A SMALL HANDFUL IN THE 1970’S. NOW ESTIMATES FORTHE POPULATION ARE IN THE HUNDREDS, AND ITS THREATENED STATUSIS BEING EVALUATED.
  13. 13. THE WEST-INDIAN MANATEE HAS A POPULATION SIZE OF LESS THAN2,500 AND IS EXPECTED TO DECLINE BY 20% OVER THE NEXT TWOGENERATIONS.
  14. 14. FLORIDA TORREYA, IS A PLANT FOUND IN NORTHERN FLORIDA ANDSOUTHERN GEORGIA ALONG THE APALACHICOLA RIVER. THE HISTORY OFITS DECLINE WAS FIRST OBSERVED IN 1938, AND BY 1962, NO ADULTINDIVIDUALS COULD BE FOUND IN THE WILD.
  15. 15. THE MAIN TWO ISSUES THAT HAVE LED TO THE DECLINE IN POPULATIONOF THE AMERICAN CROCODILE ARE HABITAT LOSS, AND ILLEGALPOACHING (NATIONALGEOGRAPHIC.COM). TOP PREDATORS PLAY A KEYROLL IN KEEPING AN ECOSYSTEM HEALTHY AND RUNNING.
  16. 16. ACCORDING TO THE IUCN’S RED LIST OF THREATENED SPECIES,AMERICAN ALLIGATORS ARE ENDANGERED, ALTHOUGH THEY ARE LISTEDAS A LOW RISK SPECIES
  17. 17. I CHOSE THE RED-COCKADED WOODPECKER AS A SPECIES THAT EXTRAEFFORT SHOULD BE EXPENDED ON PROTECTING. THE RCW CAN BE FOUNDTHROUGHOUT THE SOUTHEAST, BUT ONLY MAKES ITS NEST IN OLDGROWTH LONG-LEAF PINE (PINUS PALUSTRIS)
  18. 18. STAGHORN CORAL CONSISTS OF 160 SPECIES AND REPRESENTS ONE-FIFTH OF THE EARTH’S CORAL. THEIR ROLE IS TO BUILD THE CORAL REEFSYSTEM AND PROTECT HABITATS FOR OTHER MARINE SPECIES FROM“HIGH ENERGY WAVES” (FAU). HOWEVER, THEIR POPULATION HASREDUCED OVER 80 PERCENT IN THE PAST THIRTY YEARS (ACROPORA).
  19. 19. SHARKS ARE AN APEX PREDATOR, AND THEY ARE SEEING PRESSURETWO FOLD FROM HUMANS. AS WE FISH THE SEAS BARREN, THE SHARK’SFOOD SUPPLY IS COMPROMISED. THEY ARE ALSO BEING HUNTED FORTHEIR FINS. “FINNING” IS THE PRACTICE OF CUTTING THE FINS OFF THESHARK AND THROWING IT BACK INTO THE OCEAN, TO DIE.
  20. 20. COMMONLY KNOW AS SCHAUS OR ISLAND SWALLOWTAIL BUTTERFLY ISENDEMIC TO FLORIDA AND FOUND IN UNDISTURBED TROPICALHARDWOOD HAMMOCK AND SURROUNDING SCRUB AREA. FIRST LISTEDAS A FEDERAL THREATENED SPECIES IN 1976, IT WAS LISTED ASENDANGERED IN 1984
  21. 21. SOME FACTORS THAT ARE ATTRIBUTED TO THE RAPID DECLINE OF THETHE LOUISIANA PINE SNAKE ARE: INTENSIVE PINE SILVICULTURE ANDALTERATION OF PRE-EUROPEAN FIRE REGIMES.
  22. 22. MY ENVIRONMENTAL EDUCATION SINCE GRADE SCHOOL WAS FOCUSEDON OUR LOCAL ECOLOGICAL SYSTEM, THE ESTUARIES, MANGROVES, ANDTHE LAGOON, THROUGH THE ENVIRONMENTAL STUDY CENTER AS I GREWOLDER I VOLUNTEERED AT ESC AND HAD A FIRST HAND EXPERIENCEWATCHING A LOGGERHEAD TURTLE DIE BECAUSE OF HUMANS. EVERSINCE THEN I HAVE HAD A SPECIAL INTEREST IN THEM.
  23. 23. FRANKLIN’S BUMBLE BEE IS CURRENTLY LISTED UNDER CRITICALLYENDANGERED PRIMARILY BECAUSE OF HUMAN IMPLICATIONS;PESTICIDES THAT CAUSE DISEASE, AND AGRICULTURE THAT CAUSESHABITAT LOSS (IUCN). IF WE DO NOT SAVE THIS SPECIES, OUR PRECIOUSNATURAL FOOD POLLINATORS WILL BE GONE FOREVER!
  24. 24. THE NASSAU GROUPER AND OTHER GROUPERS ARE EATING THELIONFISH, WHICH IS AN INVASIVE SPECIES IN THE CARIBBEAN. THEGROUPER IS ONE OF THE ONLY POTENTIAL THREATS TO THIS INVASIVESPECIES. THE GROUPER EATS THE LIONFISH’S EGGS, WHICH PREVENT ITFROM REPRODUCING.
  25. 25. SINCE EVEN EXPERTS ARE UNSURE OF THE STATUS OF THE IVORY-BILLEDWOODPECKER, I BELIEVE IT IS IMPERATIVE THAT SPECIAL EFFORTS AREMADE TO SAVE THE FEW IF ANY.
  26. 26. THE FOUR-PETAL PAWPAW IS NATIVE TO FLORIDA AND HAD BEENENDANGERED SINCE 1986. IT HAS BEEN BLOCKED FROM THE SUN BYOAKS AND PINES RESTRICTING ITS GROWTH. IT IS ALSO LOW IN NUMBERDUE TO COMMERCIAL AND RESIDENTIAL DEVELOPMENT.
  27. 27. ELKHORN CORAL IS LISTED AS A CRITICALLY ENDANGERED SPECIES. IT ISIN DECLINE FOR A MULTITUDE OF REASONS, INCLUDING CLIMATECHANGE, HUMAN IMPACT, AND DISEASE. WHITE BAND DISEASE HASATTACKED ELKHORN CORAL SINCE THE 1980’S.
  28. 28. EVEN IN TECHNOLOGICALLY-ADVANCED COUNTRIES LIKE THE USA, HALFOF THE 100 MOST-PRESCRIBED DRUGS ORIGINATE FROM WILD SPECIES.AMPHIBIANS PLAY A VITAL ROLE IN THE SEARCH FOR NEW MEDICINES ASIMPORTANT CHEMICAL COMPOUNDS CAN BE FOUND ON THE SKIN OFMANY FROGS
  29. 29. ACCORDING TO IUCNREDLIST.ORG, THE HABITAT OF THE FLATTENED MUSKTURTLE IS CURRENTLY LIMITED TO “A SINGLE DRAINAGE SYSTEM INALABAMA… FROM POLLUTION AND SEDIMENTATION FROM NEARBY OPENCOALMINING, AND IMPOUNDMENT OF STREAM SECTIONS.”
  30. 30. I CHOSE THE GEORGIA OAK AS MY SPECIES THAT NEEDS SPECIALATTENTION, BECAUSE NATIVE TREE SPECIES ARE BECOMING MORE ANDMORE THREATENED. TREES PROVIDE HABITATS FOR MANY DIFFERENTSPECIES OF PLANTS AND ANIMALS, ALSO NATIVE TREES ARE MOREADAPTED TO THEIR HABITATS.
  31. 31. GRAY BATS, LIKE MANY OTHER ENDANGERED ANIMAL SPECIES, ARETAKING THE HARDEST HIT DUE TO LOSS OF HABITAT. THEY ARE FOUND INCAVES YEAR ROUND, WHICH MAY MAKE THEM MORE VULNERABLE TOHUMAN DISTURBANCE SUCH AS MAN MADE FLOODING AND PESTICIDES.
  32. 32. THE DECLINE OF EASTERN INDIGO SNAKE DUE TO LOSS OF HABITAT, THEYLIVE IN LONG LEAF PINE FORESTS WHICH MANY HAVE BEEN DESTROYEDAND CONVERTED TO SLASH PINE OR OTHER LAND USAGE.
  33. 33. THE SPINY RIVER SNAIL IS OVERLOOKED TREMENDOUSLY, BUT IS VITAL TOTHE ECOSYSTEM OF OUR RIVERS IN THE SOUTHEASTERN UNITED STATES.
  34. 34. THE KEMP RIDLEY SEA TURTLE HAS BEEN ENDANGERED SINCE 1986 ANDIS CURRENTLY CLASSIFIED AS CRITICALLY ENDANGERED1. BOTH THEIXTOC1 RIG BLOWOUT AND THE DEEPWATER HORIZON OIL SPILL HAVEBEEN ESPECIALLY DESTRUCTIVE ON THIS SPECIES3.
  35. 35. I CHOOSE THIS ANIMAL BECAUSE IT LIVES IN GEORGIA. I AM FROMATLANTA, AND MUSSELS ARE A PART OF MY REGULAR DIET. THE DECLINEOF THIS ANIMAL IS SEVENTY-EIGHT PERCENT OVER THE LAST FOURTEENYEARS.
  36. 36. THROUGH HUMAN DESTRUCTION OF ITS HABITAT, WE HAVE WIPED OUTNEARLY THE ENTIRE RED WOLF POPULATION. AS A RESULT, DEERPOPULATIONS AND OTHER PREY SPECIES ARE NOT IN PROPORTION TOTHE BALANCE OF THE ECOSYSTEM.
  37. 37. THE PASCAGOULA MAP TURTLE RANGE IS LIMITED TO THE PASCAGOULARIVER SYSTEM OF MISSISSIPPI. SINCE 1950, THE POPULATION HASDECLINED BY 80 TO 90%. THIS IS LARGELY DUE TO WATER POLLUTIONTHAT IMPACTED MOLLUSKS, THE TURTLE’S FOOD SOURCE.
  38. 38. I have seen three of River Birch these plants and will Florida Buckeye probably see more in my forest conservation class soon. Florida MapleClimbing Aster Devil’s Walkingstick
  39. 39. I have only seenEastern Indigo Snake the whooping crane Florida Scrubs-Jay out of these five animals. Whooping Crane Florida Manatee Kemp’s Ridley Sea Turtle
  40. 40. I chose this endangered species because many people are not awareof the “sea cow’s “endangered status. I did not know it was endangeredand have not heard about many efforts to protect the animal till now.More Floridians need to be aware of these creatures when enjoying thewaters of the state. Combinations of state and federal agencies havebeen proficient in reducing the loss of manatees. Andrew Aloise notesthat Florida Manatee Refuge Officers and U.S Fish and Wildlife Servicehave created speed zones to avoid hitting the slow moving mammal. Healso states that enforcement has not always been comprehensive, buthas come very far in the last 20 years.
