Reed Bed Catchup

Reed bed on water Coarse
It was November 2011 when we dug out the reed bed and silt trap at the far end of the farm to try and intercept the ditch water and improve the quality of the outfall into the Carrant Brook.  The silt trap was used to slow down the water and allow the heavier particles (of silt) to drop out of the water.  The water then carried on through the reed bed in a shallow wide spread to allow the roots of the reeds to take nutrients, nitrate and phosphate, are he main two form the water and capture those nutrients in the form of plant material.
After quite a slow start the reed bed has really taken off providing a great habitat for bird species like reed buntings as well as a more general habitat improvement next to the hedge and copiced willows. We have just started a water sampling project with Gloucestershire University, so it will be really interesting to see what effect a very small investment in time and energy can have on the water leaving the farm.
