Welcome back to our "yeah we get it, you're still talking about trees in bioretention - series"

This time, something really interesting. The past episodes were interesting, but this fascinated us when we spotted it. Succession. The Hoyland St bioretention system is old. Some of the plants are dying. But a new wave might just be coming through. This is probably the first time ever that succession has been observed in a bioretention system!
