Volunteer’s making a difference.

The Saturday volunteer group worked very hard installing a ‘Brushwood mattress’ at The Rush stream on Sheep’s Green. The idea is that the brushwood collects passing silt and by doing so creates a narrowing of the channel. This narrowing increases the flow of water which in turn creates a faster more dynamic section of the stream, keeping the bottom gravel clear and oxygenating the water. Vegetation soon grows through the mattress helping to hold it all in place and offering an added habitat and shelter for fish and invertebrates.
