Native tree planting in Cranberry Clough, Howden Moors. This initiative, lead by Moors for the Future www.moorsforthefuture.org.uk, looks to bolster native clough woodland, steep-sided woodland on the edge of open moorland. Clough woodland has become increasingly fragmented over the years, impacting on biodiversity and leading to soil eroision that in turn affects water quality.
