Dragonfly sculpture

The wooden sculptures depict some of the wildlife that can be seen around the reserve and on the adjacent Stort Navigation.

The barn owl, dragonfly, water vole, woodpecker and otter seat were all commissioned by Herts & Middlesex Wildlife Trust, who own Thorley Wash, and were carved by local artist Dan Cordell

Tree work at Singlers Marsh

Another project on the Catchment Plan is now green!

Contractors started work this morning on Mimram project 19, 'Windows of Vision' at Singlers Marsh, Welwyn. 

AG Treecare Ltd have started clearing overshading scrub from alongside the B656 Codicote Road, to allow more light to reach the river.  They will also pollard some of the very large trees on the marsh side of the river.

You are invited to an evening of short talks focussed on current scientific research into chalk stream restoration and monitoring. Speakers include researchers from London’s Natural History Museum, the University of Hertfordshire & University College London.

Herts & Middlesex Wildlife Trust's Charlie Bell was interviewed on BBC Three Counties Radio on 19th Feb. She was talking about our rare local chalk streams, including the Beane and Mimram, and the Catchment Management Plan.

The Catchment Partnership now has a Twitter account – @StortWildlife. The main purpose of this is to allow people to Tweet their wildlife sightings from in and around the river. This will automatically link to the 'Wildlife Sightings' section of this website.

River bed improvement upstream of Tewinbury Farm

This stretch of river suffers from heavy silt deposition caused by reduced flows, dredging in the 70s, and the ponding effect of a weir. The aim is to restore the river to a silt-free, gravel bedded, shallow, fast flowing stream, with riffles and pools capable of supporting water crowfoot and breeding trout.
