Potential MPAs for Sea Turtleand Coral Reef Conservation

in Indonesia

Introduction to Spatial Analysis with GIS Course Project

By: Nara Wisesa

Background

• Idea – To find potential MPA sites in Indonesia for:

• Coral reefs• Or Sea turtle breeding area• Or both at the same time

Finding Suitable Data• Find data for global coastline

(http://www.ngdc.noaa.gov)

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

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

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

Putting Things Together

• Add Coastline data

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

Putting Things Together

• Add Global Coastline data• Import KML file of existing MPAs and turtle

migration routes• Add Coral Reef and Indonesian Coastline

data

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

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)

• 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

Data Analysis

Products

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

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

Final Product

thank you!

For protecting me!! :)
