Hi! I'm Caitlyn

I'm a marine ecologist and environmental scientist. I'm working on understanding seagrass resilience in estuaries at the Department of Water and Environmental Regulation. I'm also researching seagrass recovery from grazing pressure at Edith Cowan University.

At the department, we focus on monitoring seagrass ecosystems as an indicator for estuary health. This forms part of a coordinated effort in the estuary and their catchments to protect the values that depend on healthy estuaries: thriving ecosystems, liveable communities, and economic development. Check out Healthy Estuaries WA for more information. Before joining the department, I started my Master's project tracking seagrass recovery from grazing.
