Micro SuDS Maintenance - How Worms Help Maintain Rain Gardens

Sustainable Drainage Systems (SuDS) are an essential tool in modern urban planning, helping to mitigate flood risk, improve water quality, and enhance biodiversity. Among the various components of SuDS, rain gardens stand out for their ability to manage stormwater naturally. However, one often-overlooked factor in their long-term effectiveness is the role of soil-dwelling organisms—particularly worms. These unassuming invertebrates play a crucial role in maintaining the functionality of rain gardens by aerating the soil, breaking down organic matter, and enhancing nutrient cycling.
