If you have ever struggled to find an invertebrate consultant or consultancy with the right experience and credibility, we may have a solution for you. You may be aware that some invertebrate species are protected under the Wildlife and Countryside Act 1981 (as amended), as well as the Conservation of Habitats and Species Regulations 2010. However, in addition, many species of invertebrate are Priority Species in the UK Biodiversity Action Plan. As such, planning authorities need you to consider these species as part of planning applications and to ensure they are protected in accordance with legislation or Biodiversity Action Plan Targets. Many planning authorities also request that you take into account Red Data Book and other notable species in ecological assessments.

As the most experienced ecological consultancy and contractor in the UK, Ecosulis employs trained invertebrate surveyors, experts and licence holders (e.g. for white-clawed crayfish, southern damselfly) and also has a wide network of reliable experienced contacts to assist with surveys and identification on larger projects.
