Biosecurity in Arboriculture

“Biosecurity – a set of precautions to prevent the introduction and spread of harmful organisms – pests, pathogens or invasive species.”

At Beechwood Trees and Landscapes Ltd we have recently been updating and reviewing our systems and procedures, as we strive to raise the levels of biosecurity awareness throughout our workforce and to promote this awareness to our customers and suppliers.


Simon Rotheram, our Managing Director recently attended a talk by James Roberts from the Forestry Commissions Health Team regarding biosecurity in arboriculture.

The number of pests and diseases being recognised nationally is increasing. Some of the significant ones include:

  • Chalara or ash dieback
  • Oak processionary moth (Thaumetopoea processionea)
  • Phytophthora
  • Sweet chestnut blight (Cryphonectria parasitica)
  • Oriental chestnut gall wasp (Dryocosmus kuriphilus)
  • Sirococcus blight

 Further reading and information on the above can be found on the Forestry Commission Website

All of our company managers have now undertaken training modules in biosecurity to increase our knowledge and help us to plan when we are working on sites our trees that potentially have pests or diseases.

We are committed to planning and managing our business activities to ensure the possibility of introduction and spread of pest and disease is kept to a minimum.

If you would like further advice on a suspected pest or disease, or your tree health in general then please get in touch, one of our arboricultural consultants will be happy to assist: 0800 3287988 or
