Some brief guidance on biosecurity. 

 

Some brief guidance on biosecurity.

 In the light of the ash dieback outbreak it is worth reminding ourselves of the actions and biosecurity measures the Forestry Commission recommend we take when moving around the countryside.

Be informed and vigilant: Be aware of symptoms and frequently inspect ash trees in your care – in particular any which have been planted during the past 5 years. There is good information on the Forestry commission websitehttp://www.forestry.gov.uk/chalara

If you see it, report it:  If you suspect Chalara dieback report it to the Forestry Commission or Fera

Practice good biosecurity control: Below are some simple measures to take to reduce the spread of plant disease including ash dieback.  We should make these part of everyday practice.

1. Plan your visit: It is good practice to discuss the visit with the occupier or manager beforehand to identify constraints/restrictions/additional controls.

2. Ensure all your equipment is clean and serviceable

3. Restrict the equipment taken onto the premises: Only take what you need.

4. Do not take vehicles further into the site than necessary: Leave at designated car parking areas.

5. If cleansing and disinfection is likely carry the necessary equipment: We suggest:

 Propellar disinfectant or another approved disinfectant

 Plastic storage box

Supply of clean water (approx 5L) 

Boot tray or bucket

Hard brush

Yachting flare container for Propellar (this is vapour proof and helps comply with the propellar data sheet/risk assessment for flammable products)

Eye protection

Protective gloves 

Hand sanitiser / wipes and paper towels

Selection of re-sealable bags (for samples)

Plastic bags and ties (so that clothing/PPE can be taken offsite for cleaning or disposal) 

Low risk level: This is the minimum level to be practiced when entering any land or premises where there are no suspected tree pests present.

Ensure footwear is clean prior to the visit (visually free from loose soil and plant debris).

If necessary brush or wash in soapy water before the visit. Make use of any facilities provided at the premises to clean footwear if required by the site manager

Ensure that vehicles are cleaned regularly to remove any accumulated mud, especially from wheels and wheel arches

Keep vehicular access to a minimum: do not enter areas unnecessarily and where practicable, keep to established hard tracks

Respect any notices or instructions.

High risk level: This should be applied before entering a woodland or a nursery/premises where a damaging tree pest is known or suspected to be present and there is a risk of spreading the pest further.

Clean and disinfect footwear.  Propellar is a recommended disinfectant available from Evans chemical supplies. Tel: 01209 213 643. Clean off mud and debris. Once clean, spray the boot/sole or equipment with disinfectant solution until it runs off. It has the advantage of evaporating quickly and does not pose a high level of risk to water courses. It may therefore be used as a good general purpose disinfectant.

Some disinfectants can be harmful particularly if inhaled or if they come into contact with skin and you should wear appropriate protective equipment such as gloves and eye protection when making up the disinfectant mixture. Propellar is ready diluted in a spray container and is simple to apply.

Clean and disinfect tools, particularly cutting equipment such as secateurs or knives after each time they are used and before moving on to the next plant or tree.

If vehicles have entered an area where a damaging tree pest is known or suspected to be present, and have been taken off hard roads, ensure that the tyres and wheel arches are adequately cleaned and disinfected well away from drains and water courses and before leaving the site.
