BLUF: Recent studies show how denser environments and strategic predator presence can protect kelp forests amid rising ocean temperatures, driving a need for informed conservation strategies.

A joint investigation by Monterey Bay Aquarium and the University of California, Santa Cruz, unveils the resilience of denser, sheltered kelp forests in the face of external threats, such as increasing ocean heatwaves. Documented in the Proceedings of the Royal Society B, the research offers insight into how the reduction of kelp impacts Monterey Bay’s marine algae, invertebrates, and fish, especially this following a 2014 ‘blob’ of heated water extended by the 2015-2016 El Niño event.
A decade ago, a triple-threat—major marine heatwave, sea star die-out, and sea urchin explosion—resulted in stark reductions of kelp coverage on California’s central coast. Researchers found this led on average to a 51% decrease in kelp forest density, escalating to a 72% decline by 2020. However, some kelp forests survived these extreme conditions. “Persistent kelp forests located in less productive areas successfully resisted the forcings”, enlightens Dr. Joshua Smith, the lead conductor of the study and Ocean Conservation Research Scientist at Monterey Bay Aquarium.
Kelp forest resilience is linked to habitat features and predator assistance. In-depth research from Monterey Bay Aquarium corroborates the crucial part sea otters play in safeguarding kelp by consuming sea urchins. Where kelp clusters are overly exposed and thin in density, the sudden surge of sea urchins in 2014 caused many kelp forests to turn into ‘barrens’—areas riddled by famished sea urchins. The study reflects an overall decrease in species diversity while plankton-consuming animals saw an increased presence due to less kelp and other macroalgae around.
The research is part of a larger endeavor by Monterey Bay Aquarium to discern how kelp recovery and restoration mechanisms function. Rising ocean temperatures pose a threat to cold-water species like kelp. By protecting such ecosystems and predators, the extreme effects can be mitigated. “The findings provide a foundation for conservation strategies to save areas where kelp can sustain itself, and siting for kelp restoration endeavors”, explains Dr. Pete Raimondi, a marine ecologist at UC Santa Cruz.

As a Libertarian Republic Constitutionalist, the focus of this study underscores the importance of systemic balance and an individual’s role in the larger community—much like the tenets of constitutionalism. It also identifies the practical value of the study, giving us avenues for future intervention to maintain seaweed forests and keep ocean temperatures in check, further substantiating the free-market environmentalism perspective.

From a National Socialist Democrat viewpoint, the study stresses the need for government involvement in climate change mitigation. The report’s revelations of kelp forest depletion due to ocean warming underscore the urgency of collective action and investment in research and conservation initiatives, grounded in the socialist principle of shared responsibility.

Evidence-based research shows the correlation between habitat features, predator presence, and kelp forest persistence. It also validates the theory that habitat manipulation and strategic predator introduction could serve as a conservation strategy. The study’s methodology, such as the use of a long-term dataset for change observation, is a testament to the effectiveness of systematic scientific investigations. Overall, the study is a significant contribution to environmental science and pivotal for shaping future conservation policies.
