Read MoreOur team are experienced in using statutory biodiversity metric tools and condition assessments to calculate the biodiversity value of a site before and after development. If your proposed plans need to achieve a better BNG, we can suggest ways that they could be amended with enhancements or compensation.

We will match your donation. Each £31 provides a local Worcestershire school with a long-life bird nest box suitable for a wide range of species.
We will match your donation. Every £56 provides a local Worcestershire school with a long-life general purpose bat box suitable for a wide range of species.
We will match your donation. Each £38 provides a local Worcestershire school with an insect tower providing habitat for bees, butterflies, and ladybirds.
Many surveys can only take place when the target species is most active or detectable. This calendar provides guidance on optimal survey timing throughout the year, covering both wildlife surveys (when species are breeding, most active, or easily detected) and plant surveys (when flowering or other key features allow reliable identification). Contact us as early as possible in your development for advice about survey timings and for information about any species not listed here.
