How to take part

Anyone can take part in the bluebell survey. Our guidance on bluebell identification is designed to be accessible to everyone.

Bluebells can be found in gardens, local parks, hedgerows or woodland. Wherever they grow, we'd like to hear about them. Just follow the simple instructions on this page and then send us your observations.

Recording tips

  • Limit your observations to the same patch or clump of bluebells.
  • Look at several specimens from the clump.
  • Focus on plants in your garden or local area. This will make it easier for you to see when they start flowering. It will also mean that you can provide us with data from the same plant in future.
  • Please note the location of the bluebells you survey as accurately as possible, ideally their grid reference.

If you have any questions please contact us.

How to find the grid reference of your bluebells

You can either use an Ordnance Survey map (watch this YouTube video by the Ordnance Survey to find out how) or a website such as UK Grid Reference Finder:

  1. Go to UK Grid Reference Finder.
  2. Enter a post code or location into the search function.
  3. Pinpoint the exact location of your bluebells on the map and right click to add a drawing pin symbol.
  4. Read the corresponding grid reference listed below the map.
