BFF Criteria

  1. Offer forage providing good nutrition for bees on at least 3% of land. Forage can be temporary, including cover crops.1–6
  2. Provide bloom of different flowering plants throughout the growing season, especially in early spring and late autumn. There is no minimum land coverage for seasonal bloom.7–18
  3. Offer clean water for bees if not inhibited by government mandated water restrictions.19–21
  4. Provide permanent habitat for nesting through features such as hedgerows, natural brush, buffer strips, or bare ground.7,8,22,23
  5. Practice Integrated Pest Management (IPM); reduce or eliminate the use of chemicals.7,8,15,16,24
