Use of GIS to find Potential MPAs for Sea Turtle and Coral Reef Conservation in Indonesia Introduction to Spatial Analysis with GIS Course MESPOM Project

1. Potential MPAs for Sea Turtle
and Coral Reef Conservation
in Indonesia
Introduction to Spatial Analysis with GIS
Course Project
By: Nara Wisesa

2. Background
• Idea
– To find potential MPA sites in Indonesia for:
• Coral reefs
• Or Sea turtle breeding area
• Or both at the same time

3. Finding Suitable Data
• Find data for global coastline
(http://www.ngdc.noaa.gov)

4. Finding Suitable Data
• Data for Existing
MPAs
– World Database on
Protected Areas
(http://www.wdpa.org)
– Managed to find
polygon of existing
MPAs
• Google Map KMZ files,
need to be extracted
and converted into KML

5. Finding Suitable Data
• Data for Coral Reefs in
Indonesia
– Reef Base
(http://www.reefbase.org)
– Managed to find datasheet of
coral reef sites
• However, it is a point-data,
not a polygon
• Therefore, a 2 km buffer
would be used around each
point to approximate extent of
reefs
• Data for Indonesian coastline
– Coral Reef data also provides
coastline data of Indonesia
• Possible to create coastal
buffer

6. Finding Suitable Data
• Data for Sea Turtle breeding
sites in Indonesia
– OBIS SeaMap
(http://seamap.env.duke.edu)
– Could not find data on exact
locations
– Managed to find satellite tag
data on sea turtle migration
routes – used as proxy
• Breeding sites would be
approximated as areas where
migration routes intersects
with the coastline buffer zone
• Also Google Map KMZ files,
need to be extracted and
converted

7. Putting Things Together
• Add Coastline data

8. Putting Things Together
• Add Coastline data
• Import KML file of existing MPAs and turtle
migration routes
– Merge MPAs into one data layer
– Merge turtle routes into three data layers,
separated by species

10. Putting Things Together
• Add Global Coastline data
• Import KML file of existing MPAs and turtle
migration routes
• Add Coral Reef and Indonesian Coastline
data

12. Putting Things Together
• Add Global Coastline data
• Import KML file of existing MPAs and turtle
migration routes
• Add Coral Reef and Indonesian Coastline
data
• Add map of countries and ocean

14. Data Analysis
• Create Buffers for:
– Coastline (potential MPAs should be within 2 km
from the coastline)
– Coral reef sites (reef areas are approximated to
extend for 2 km around each site)
– Turtle migration routes (turtles approximately
spread 1 km around their migration routes)

16. Data Analysis
• Perform Map Analysis
– On coastline buffers and reef buffers to
calculate potential MPA for coral reefs
– On coastline buffers and turtle route buffers to
calculate potential MPA for turtle nests
– On coastline buffers reef buffers and turtle
route buffers to calculate potential MPA that
would protect both

20. Products
• Potential MPA for Coral Reef
• Potential MPA for Sea Turtle Nests
• Potential MPA that protects both

21. Products
• Map of potential MPAs all over Indonesia
– Hard to comprehend, scale too big
• Focus on Potential MPAs that protect both
– Only found in Bali

22. Final Product

23. thank you!
For protecting me!! :)
