Bees

Protecting bees on Irish farms

In this video, Aoife Leader, Walsh Scholar explains the importance of bees to the environment and biodiversity on Irish farms. Aoife identifies the simple measures farmers can take to help protect bees on their farm.


There are 98 species of bees in Ireland, one third of which are threatened with extinction.

Why are bees important?

  • Pollination of food crops(Oilseed Rape, Peas, Beans, Apples, Soft Fruits)
  • Pollination of wild flowers and trees
  • Production of honey
  • Bees can be used to show a green image for Irish food

Why bee numbers are declining?

  • Reducion in wildflowers. Pollen provides protein for bees while nectar provides carbohydrates
  • Less nesting sites for bees
  • Lack of continuity of flowering plants: Bees require food all year round, requiring a diversity of flowering plants in the landscape

How can farmers help bees?

Allow space for diversity of wildflowers to grow

Along farm roadways, around farmyards, around field margins, in the corners of fields

Field Margins

  • Fence off from livestock
  • Cut or graze after flowering
  • Do not fertilise
  • Do not spray

Non farmed areas - around the farmyard, in field corners, along farm roadways

  • Allow flowering plants to flower
  • Do not spray
  • Do not cut until after flowering

Spraying insecticides in tillage crops

  • Spray early morning and late evening when honey bees are less active
  • Notify local beekeepers

Hedgerows

Irish hedgerows are full of flora and fauna if well managed. They are of value to pollinators only if flowers are present. A variety of hedgerow types is desirable on every farm.

  • Aim for a diversity of flowering plants - allow mature trees, new saplings and climbers grow and flower
  • Allow wildflowers to grow at the base
  • When cutting the hedge, side trim to a triangular shape with a wide base
  • Leave the peak on the hedge as high as possible
  • Allow individual thorn trees mature at irregular intervals

Bee boxes

Some solitary bees are cavity nesters and nest in hollowed twigs or holes in wood or masonry.

Making a Bee Box

  • Wood - not treated with insecticide / preservative
  • Selection of hole sizes - between 3/8 and ¼ inch
  • Clean smooth holes
  • Selection of holes - Include hollow stems e.g. bamboo
  • Holes must not interconnect - dead-end required
  • Pack with subsoil - substitute clay bank

When placing the bee box, it is important to have the box near flowering plants, at least 40 cm off the ground, in a sheltered and sunny spot facing south to south-west and fixed firmly, as bees will be navigating home to the bee box.
