Rake method?
Natural waters provide numerous ecological benefits, including biodiversity, water purification, and landscape formation. However, the presence of unwanted root water plants such as exotic species can sometimes disrupt natural processes and restrict the use of water for recreation and other purposes. In such cases, it is important to remove these plants to protect the health of the ecosystem and keep the water safe for human use. The rake method is a unique, standardized, and proven method for removing root water plants. It is essential that the rake method is carried out by experienced and qualified professionals who take into account ecological conditions and the environment. Proper application of the rake method can not only remove unwanted plants but also improve biodiversity and water quality.
Way of working matters:
Work in a safe, responsible and sustainable manner
Taking into account ecological conditions
Taking the environment into account
Knowledge and skills of workers
Prevent the spread of alien aquatic plants in work
Standardization provides clear guidelines for water managers for the execution of work
This method was laid down in a European standard in September 2022, the CWA 17916:2022 and entitled: “Rooting nuisance (alien) aquatic plants – Control by means of rake method with a boat.”
The standard can be requested in each EU country from the national standardization institute of that country.
Normalize methodology for quality assurance of the work
In October 2021, this standard was laid down in a Dutch Technical Agreement. The NTA 8037:2021 en entitled: “Wortelende ongewenste (exotische) waterplanten – Bestrijding door een harkmethode met een boot.”
