Algae in Marlborough
Algae are a diverse group of photosynthetic organisms that are usually found in aquatic environments. Not to be confused with blue-green algae, which are photosynthetic, but more closely related to bacteria, algae range from giant kelp to unicellular phytoplankton. Green, brown, and red algae are some of the different major groups, with many of the larger marine algae more commonly known as seaweed. Although algae are sometimes referred to as plants, unlike plants, they produce sperm and eggs, and require water for fertilisation.
On land, some algae form a symbiotic relationship with fungi in the form of lichens, which are capable of colonising some of the harshest environments on earth.
In Marlborough, algae can be found from the coast to some of the region's highest mountains in various forms. A few introduced species like didymo are invasive pests.
Kelp is farmed commercially in Tory Channel.
