It’s a big moment.. Saturday marked the first ever Estuary Edges litter survey on the Thames Estuary. But what does this mean? Well my dear Londoners, strap in.
If you haven’t read any of my previous posts, you wont know that I am the Thames Estuary Edges Officer. Estuary Edges are a series of works initiated by the Environment Agency in the ‘90s that aims to replace brick, concrete and metal tidal walls with natural habitat such as reeds to encourage biodiversity and SuDS (Sustainable Urban Drainage Systems) along the River Thames. These precious green infrastructure sites had never before been monitored for their ecological value, or for how litter interacts with the reeds. This is where my role comes in (hair swish..)
Thames21 (a charity that focuses on educating the public on litter pollution), volunteers and myself completed the first litter survey of 2020 at Battersea Estuary Edges site. For all the nerds out there; we used 1 x 1m quadrats along a transect line that spread across the whole site. The plastics were then categorised by size e.g. macro and micro plastics.
This survey programme will assess types of litter at the Estuary Edges reedbeds, influencing future designs to prevent litter collecting at the sites. We hope this research will encourage more Thames waterside developers to implement these biodiverse habitats!
