What  is  GIS?  •  A  geographic  informa$on  system  (GIS)  integrates  hardware,  soLware,  and  data  for  capturing,  managing,  analyzing,  and  displaying  all  forms  of  geographically  referenced  informa$on.

Understanding  Spa$al  Pa(erns  

     Used  to  make  future  management  strategies  

Can  reflect  past  condi$ons  Shows  the  effects  of  habitat  altera$on  

Examine  areas  that  are  desirable  for  nes$ng

Future  Research  

•  Map  addi$onal  years  to  see  trends  and  correla$ons  in  nes$ng  on  Bald  Head  Island  

•  Examine  the  return  rate  of  turtles  based  on  their  PIT  tag  ID  number  and  flipper  tags  

•  Overlay  a  beach  nourishment  layer

Acknowledgements  

 I  would  like  to  thank  Jaymie  for  her  support  during  this  process  and  for  providing  me  with  all  of  the  current  nes$ng  data.  I  would  also  like  to  thank  Patrick  for  providing  with  the  GIS  soLware  that  was  needed  to  carryout  my  project.
