What’s living in your hedge?

Join in now. The best time to do this survey is from April to November.

Take part in the OPAL Biodiversity Survey and uncover the diverse range of wildlife in our hedges.

Hedges support many animals by providing food and shelter. Berries and seeds are food for birds, while holes beneath the hedge are often home to small mammals. You’ll also discover many invertebrates living among the leaves.

  • Step 1: Download the easy-to-follow instructions and guides in English, below, or in Welsh.
  • Step 2: Find a suitable hedge to carry out the survey and answer the questions in the workbook. Use our guide to help you identify invertebrates.
