Eco Timings Guide

This guide gives you an outline of optimal timings for survey and mitigation for a range of species.  It is currently being updated, so watch out for a new interactive version here soon!  Many ecological surveys are seasonally restricted, and early engagement of an ecologist on your project can help to ensure that surveys can be completed and appropriate avoidance and mitigation measures designed into your project, saving time and money later down the line.  Please do not hesitate to contact us should you wish to discuss specific surveys or potential requirements for your project.

 

All survey techniques can be used throughout the year.

Surveys are most effective in Spring, Autumn and Winter
