Welcome to Dendra Consulting Ltd, consultants in arboriculture and ecology.


We specialise in tree surveys, ecology surveys, bat surveys and more for projects ranging from small domestic extensions to large commercial schemes. We provide pre-planning advice, site surveys, mitigation plans and reports. Our work is tailored to your specific project, regardless of size.

We also provide mortgage and insurance reports for trees in proximity to dwelling houses, tree health & safety inspections and woodland management plans. In addition we can provide a team of trained climbers to undertake detailed aerial inspections of trees for roosting bats prior to pruning and/or felling.

Please Contact us to discuss the arboricultural and/or ecological requirements of your project. We will be happy to arrange a site visit.
