Crusty old dams

Blawhorn Moss NNR.P1080042

I get a great feeling of encouragement when I find nature taking back its own.

Work to repair the damage created by ditches started on Blawhorn 25+ years ago with the building of dams made from oak and elm planks. The dams were hard work – the timbers were heavy and needed banging in a long way to be effective but they stand as a fine testament to the efforts my predecessors made to start the recovery of Blawhorn.

As time has moved on new techniques have been devised for damming and we no longer use wood as most of the original dams no longer hold water. By they are still in situ and now provide a surface for a miniature forest of lichens and fungi. A close look reveals a number of species and a startling structural landscape 2 cm high, a thing of beauty to behold.
