Conservation through Animal Collaboration: Sea Lions Mapping Benthic Areas

How To Protect The Ocean

On this episode of the How to Protect the Ocean podcast, we explore the innovative use of sea lions to map benthic habitats in Australian waters. Traditional methods of mapping underwater areas can be costly and challenging, but leveraging animals like sea lions offers a unique solution. Join host Andrew Lewin as we delve into the importance of mapping the ocean to better protect marine habitats and species. Tune in to learn more about this fascinating approach to ocean conservation!

Using animals, such as sea lions, to map benthic habitats can be an effective and cost-efficient method for conservation and exploration. In a podcast episode, researchers in Australia discussed their successful use of camera tags on endangered sea lions to map benthic habitats in Southern Australia. By equipping the sea lions with small, lightweight cameras, researchers were able to track their movements and visually document the diverse benthic habitats they encountered.

The data obtained from the animal-borne video and movement data provided critical information for mapping previously unmapped benthic habitats on the continental shelf. This method allowed researchers to cover over 5,000 square kilometers of seabed, offering valuable insights into the habitats used by the sea lions. The resulting videos from the camera tags enabled researchers to identify various benthic habitats, including macroalgae reef, macroalgae meadow, bare sand, sponge and sand habitats, invertebrate reefs, and invertebrate boulders.

By leveraging the natural movements of these sea lions, researchers were able to gather data on a large scale without the need for expensive equipment like remotely operated vehicles or drones. This approach not only helped in mapping critical habitats for the endangered Australian sea lions but also had broader implications for surveying other marine species of interest. The cost-effectiveness and efficiency of using animals for mapping benthic habitats highlight the potential for this method to be a valuable tool in conservation and exploration efforts.

The successful use of sea lions to map benthic habitats demonstrates an innovative and sustainable approach to gathering crucial data for conservation purposes. This method not only benefits the protection of endangered species but also contributes to a better understanding of marine ecosystems and habitats, paving the way for more effective conservation strategies in the future.

Camera tags on animals, such as sea lions, have proven to be invaluable tools in gathering data on habitat use and movement patterns. In the podcast episode, researchers in Australia utilized camera tags on endangered sea lions to map benthic habitats in Southern Australia. By equipping the sea lions with small, lightweight cameras, researchers were able to track their movements and visually observe the different habitats they encountered. This innovative approach allowed for the mapping of over 5,000 square kilometers of seabed, providing critical information for the protection of the endangered Australian sea lions.

The use of camera tags on animals not only aids in the conservation of specific species but also contributes to broader marine conservation efforts. By studying the habitat use and movement patterns of marine mammals like sea lions, researchers can gain insights into the diversity and distribution of benthic habitats. This information is essential for effective marine conservation planning, as it helps identify critical habitats for protection and informs management strategies for endangered species.

The success of using camera tags on sea lions highlights the potential of this technology in advancing marine conservation efforts. By leveraging the natural movements of animals to gather data on underwater habitats, researchers can overcome the challenges associated with traditional mapping methods, such as the high cost of remotely operated vehicles and limited coverage of survey areas. The ability to visually observe and document habitat use through animal-borne cameras opens up new possibilities for studying and protecting marine ecosystems.

Overall, the use of camera tags on animals like sea lions represents a promising approach to conservation biology. By harnessing the power of animal movements to collect data on benthic habitats, researchers can enhance their understanding of marine environments and contribute to the preservation of endangered species and marine biodiversity.

Proper protocols and care must be followed when using camera tags on animals to ensure their safety and well-being during the research process. In the podcast episode, researchers equipped eight endangered Australian sea lions with small, lightweight cameras to track their movements and map benthic habitats. The cameras and tracking instruments were carefully attached to the sea lions using small pieces of neoprene glued onto their fur, weighing less than one percent of the sea lion's body weight to prevent any negative effects on their swimming abilities.

Furthermore, the researchers took precautions to ensure the camera tags did not hinder the sea lions' movements or cause any harm. They monitored the animals closely and recorded over 89 hours of footage over two to three days. Additionally, the researchers sedated the sea lions when retrieving the cameras to prevent any stress or harm to the animals during the process.

This approach demonstrates the importance of following proper protocols and care when using camera tags on animals for research purposes. By prioritizing the safety and well-being of the animals, researchers can gather valuable data while minimizing any potential negative impacts on the study subjects. This ethical and responsible approach is essential in wildlife research to ensure the welfare of the animals involved and maintain the integrity of the research findings.
