It looks like a weed in the sea, but it is not. Is a brown macroalgae that grows and forms “forests” which can measure up to 40 meters long. They have given him the popular name of “cachiyuyo”.
Already in the 19th century the English naturalist Charles Darwinon his trip through Patagonia, recognized the importance of macroalgae as essential for the marine environment.
During the last 50 years, in the world The threatening factors that impact the forests of different species of macroalgae increased and caused a decrease of two percent per year globally.
One of the reasons is the impact of climate change. The increase in global temperature, heat waves, pollution, the introduction of exotic species, among others, are also factors that can alter macroalgae.
When taking into account the reduction of Cachiyuyo, the Directory of the National Parks Administration of Argentina declared its conservation of institutional interest. It was established that the National Directorate of Marine Protected Areas will develop and execute projects, programs and actions aimed at research, conservation and management of the species.
The underwater parks generated by macroalgae play a crucial role in the carbon cycle. They have the ability to absorb carbon dioxide (CO2) and transform it into organic biomass.
They also provide habitat, shelter, breeding grounds and food for hundreds of marine species, such as starfish, southern dolphins, sharks and rays, and native species of great commercial value such as crab and squid (The Argentinian).
The director of Marine Protected Areas, Antonio Curtosiwill coordinate with the Atlantic provinces, both the survey of the geographical spaces of interest, as well as the strategies that are necessary for the protection of the environment where the macroalgae completes its life cycle.
