Check, Clean, Dry

As a water user, you may unknowingly be helping to spread invasive species from one water body to another in equipment, shoes and clothing.

Help stop this happening by following three simple steps: Check - Clean – Dry

Check - All clothing and equipment should be thoroughly inspected and any visible debris (mud, plant or animal matter) should be removed and left at the water body where it was found. Particular attention must be paid to the seams and seals of boots and waders. Any pockets of pooled water should be emptied.

Clean - Equipment should be hosed down or pressure-washed on site. If facilities are not available equipment should be carefully contained, e.g. in plastic bags, until they can be found. Washings should be left at the water body where the equipment was used, or contained and not allowed to enter any other watercourse or drainage system (i.e. do not put them down the drain or sink). Where possible, clean equipment should be dipped in disinfectant solution (e.g. Virkon) to kill diseases, but note this is unlikely to kill non-native species.

Dry - Thoroughly drying is the best method for disinfecting clothing and equipment. Boots and nets should be hung-up to dry. Equipment should be thoroughly dry for 48 hours before it is used elsewhere. Some non-native species can survive for as many as 15 days in damp conditions and up to 2 days in dry conditions, so the drying process must be thorough.

The River Dee Biosecurity Action Plan

The vision of the Dee Catchment Biosecurity Action Plan is:

β€œTo establish a sustainable, coherent and inclusive strategy that safeguards the River Dee Catchment in England and Wales against the threat of invasive non-native species through monitoring, action and education.”

The action plan is for use by all stakeholders throughout the Dee catchment who are, or would like to become, actively involved in its implementation.  The plan will benefit both the natural environment and the local and national economies.  By working together to prevent the spread of INNS the Dee Catchment Biosecurity Action Plan will help to safeguard and improve the quality of nationally and internationally important sites for nature conservation and improve access and enjoyment for recreation within the Dee catchment.
