We work with a variety of clients from many different backgrounds and industries including: housing developers, local district councils, public utility companies, educational establishments, conservation organisations, private companies, local authorities and government agencies. Survey work and mitigation advice is also offered to individual members of the public who may unexpectedly encounter protected species issues whilst engaged in relatively small planning applications.

Dr Brady’s expert advice regarding our protected Great Crested Newt population from initial survey to subsequent correspondence and telephone conversations with Local Authorities on our behalf were carried out with speed and efficiency. In dealings with Natural England and the Environment Agency procedures, Dr Brady’s expert knowledge and advice proved invaluable. We consider ourselves extremely fortunate to have Dr Brady working on our behalf.

Mrs. B. Pearce

We have worked closely with Calumma Ecological Services on a number of projects requiring specialist assistance on matters relating to reptiles and amphibians for more than 14 years. Projects have varied in size and complexity and we have always been impressed by the standard of work and details of knowledge presented in their reports and analyses. The consultancy has always acted professionally and carried out work to the highest standard. They have been very competitive and have always maintained good communication throughout the project.

Calumma Ecological Services is the first place I go to when it comes to aquatic surveying. Lee is extremely knowledgeable, I recommend them whenever I speak to my colleagues at the National Trust.
