Quality Control All records are validated by NDFF

Method step description:

  1. Select a moment between 1 May and 1 October
  2. Choose a suitable roadside: · In a rural area · Bordering a bicycle path or a road · A roadside that looks more or less similar across its full length
  3. Survey 100 metres of the roadside by stopping every 10 metres (or take 10 large steps) and note the nectar plants within 1 metre of where you are (10 times in total). Non-flowering plants should also be noted. The most common nectar plants are pictured on a special search map. Are you an experienced florist? You can also report other plant species with the observation form.
  4. Enter the results on floron.nl/bermen. When you enter your results, you will be asked to draw the area you surveyed on a map. After entering your figures, you will see the quality of your roadside on a scale of 1 to 5.
