The wisdom in the adage ‘everything in moderation’

If you walk alongside a river, you might notice long strands of algae called Cladophora. Marc Peipoch of the Stroud Water Research Center says this type of algae plays an important role in streams.

“Other small algae can take use of it and grow on top of the Cladophora or some insects will have some shade or will have some place to hide so that they don’t get consumed by fish.”

In many places, warmer water, and excess nutrients from farm runoff are making Cladophora grow faster than it used to. Too much can clog intake pipes, and outcompete other species, reducing biodiversity in the stream.

“A little bit is fine. Too much becomes a problem,” says Peipoch.
