Clearing mangroves makes ‘muddification’ worse

A new study found that removing mangroves in New Zealand's estuaries actually increases mud build-up, as these coastal trees and shrubs trap sediment efficiently. This highlights the need for sustainable land use upstream to address the root cause of the issue, rather than focusing solely on mangrove removal.
