DTA Ecology - providing specialist advice on the Habitats Regulations and continuing the work of David Tyldesley & Associates

Why come to DTA Ecology?

DTA Ecology Ltd was established in April 2015 to continue the work of David Tyldesley and Associates. DTA Ecology Ltd is now the consultancy arm of the DTA brand whose reputation in the field of the Habitats Regulations is firmly established through the Award Winning Habitats Regulations Assessment Handbook and accompanying Journal, published and maintained through DTA Publications Ltd. 

The DTA brand is associated with an exceptional reputation in the interpretation and practical application of the Conservation of Habitats and Species Regulations (commonly referred to as the Habitats Regulations). With a long and accomplished track record of completing often complex and demanding projects, on time and on budget, DTA has a reputation for maintaining a consistent, highly respected, forefront position in cutting edge research and professional advisory services to a quality client base, including central government, statutory agencies, local authorities and national conservation bodies. As a company policy, and in order to avoid any conflict of interest, DTA Ecology only accepts work from a public sector client base.  


DTA Ecology looks for innovative, proportionate and cost effective solutions. The company aims to resolve conflict and ensure compliance in a wide range of case work, mostly relating to plans and projects potentially affecting nationally and internationally designated wildlife sites. Whilst the majority of our work relates to the assessment of plans and projects under the Habitats Regulations, we also specialise in the provision of advice relating to the effects of air quality on designated conservation sites.

The Company operates throughout the UK and Ireland. Our office is in Wokingham, near Reading.
