Update May 2016 PC David Hart, mentioned below, is no longer a member of the West Mercia Wildlife Unit. See the West Mercia police website for the latest Shropshire contact. Main article 25 May 2015 When can developers chop down trees? The short answer is anytime. Unless they disturb nesting birds, fall foul of Tree Preservation Orders or the work is extensive enough to require a licence from the Forestry Commission. This article is about disturbing birds. It follows two recent incidences of tree cutting on developments in Ludlow during the nesting season. I am making no suggestion that birds or their nests have been harmed during these operations but I thought it would be useful to clarify what the rules are. I can’t comment on specific cases until I get further information from officers.
