 2021 BIG Biodiversity Challenge Award categories

The Awards aim to raise greater awareness of the importance of biodiversity and to demonstrate how biodiversity enhancements can be incorporated at different scales and on different projects. The awards aim to reward entries that go beyond normal business practice or planning and statutory obligations. There are 8 award categories outlined below and each enhancement can entered for up to TWO categories. You can also find an example gallery for each category here.

Judges will also select an overall winner for the enhancement that demonstrates an outstanding commitment to biodiversity.
