About the project
The Kimberley coast and nearshore waters support foraging habitat and nesting beaches for five species of marine turtles. There is limited scientific knowledge however, to understand the status of regional marine turtle stocks that face pressures such as climate change, marine debris, coastal development and increasing human contact.
Existing knowledge revealed scattered information on the distribution and relative abundance of nesting turtles. This research conducted a systematic survey of all sandy beaches for nesting turtles to gain a regional understanding.
- Identify when and where turtles nest in the Kimberley
- Develop climate change models to predict how nesting turtles might be impacted
- Work out relationships between different turtle nesting groups (genetics)
- Work with Traditional Owners to exchange traditional knowledge and western science for better management
- Record and photograph nesting along the Kimberley coast during the wet and dry season from the air using a small plane and a specialised digital camera
- Visit beaches and islands to verify the aerial survey records and collect information on species, size and hatching success (select beaches in west, central and eastern Kimberley)
- Deploy weather stations and loggers to measure nest temperatures to enable prediction of impacts to turtles through climate change
- Collect a tissue sample from turtles to work out relationships between groups of turtles at different nesting beaches
- Work in collaboration/partnership with Indigenous communities in the Kimberley including training rangers.
- Better overall knowledge of where and when turtles nest to enable impacts to be managed (developments, tourism etc.)
- Provided a knowledge base to allow monitoring of turtles into the future – information to help understand if populations are going up or down
- Developed effective and efficient monitoring methods that can be conducted over the long term
- Prediction of impacts of climate change
- Defined management units (what scale should management be aimed at)
- Standard operating procedures and manual to monitor nesting turtles to be used by marine and Indigenous rangers
- To develop a long-term monitoring program in the Kimberley in cooperation and partnership with Indigenous groups.
