In Monterey, CA, two of the dominant kelp forest-forming species are giant kelp and bull kelp. From 2014 to 2016, the largest marine heatwave in recorded history developed off the coast of CA, raising temperatures 2-5°C above average sea surface temperatures. This led to the complete replacement of acres of kelp forests with urchin barrens. We seek to explore how urchin food choices and the management of urchin barrens impact the re-establishment and abundance of giant kelp and bull kelp.
