Dan Crossett

Marine Ecologist

Role at Cawthron

Dan is a marine ecologist in Cawthron’s Restoration Ecology Team. He focuses on state of the environment monitoring and bottom-up ecological processes that may enhance recruitment of foundation species. Dan is interested in how multiple stressors impact coastal foundation species, like kelp, and the biodiversity they support. Dan’s research focus includes the effects of natural disturbances, such as earthquakes and severe weather events, and anthropogenic impacts, such as sedimentation, warming seas and overfishing, on coastal ecosystems.

The core goal of Dan’s research is to identify and implement strategies for restorative measures in areas affected by multiple, interacting stressors, such as through kelp-seeding programmes for rocky reef restoration. He also advocates for community outreach, public awareness, and educational initiatives to invoke stewardship among community groups, future scientists, and managers.
