"I recently contracted ELMS to carry out some scrub works as part of the Back from the Brink project. The aim was to diversify the structure of the woodland by thinning areas of closed canopy and the creation of glades to develop an understory for the benefit of Willow Tits. I had a very positive experience of working with Gareth in this capacity and would be comfortable working with ELMS on future projects."
