🌿 Could harvesting reeds help both the Baltic Sea and livestock farming?
A new PhD thesis from SLU suggests that harvesting overgrown reed beds along the Baltic Sea coast could offer benefits on two fronts: supporting healthier coastal ecosystems while also providing a potential source of livestock feed.
PhD student William Ashworth found that reed harvesting can help control dense reed beds, benefit other aquatic plants and, with the right harvesting strategies, support fish populations. Harvesting in July and August also removed around nine kilograms of phosphorus per hectare and year from coastal ecosystems.
The research also explored reed as animal feed. The results suggest that it can be suitable for horses with low energy demands and non-producing dairy cows, although there are limitations – including lower feed intake compared with conventional alternatives.
“If these challenges can be addressed, reed harvesting could become a practical tool for both combating coastal eutrophication and meeting growing demands for livestock feed in a more sustainable way,” says William Ashworth.
