Essex Rivers Hub

Invasive species surveys and removal

Invasive species such as Himalayan Balsam, Floating Pennywort, Parrots Feather, New Zealand Pygmy Weed, American Mink, Chinese Mitten crab and many more can be very damaging to the river habitat by dominating banks, which limits the number of native species that grow, leaving bare banks over winter increasing the amount of sediment that enters the channel, killing native species or undermining banks.

 

In order to determine the number of invasive species that are found along the Mardyke the area would need to be surveyed at the appropriate time of year and the location of these species determined. This will determine the level of control need for these species.

In some cases this will involved community help and landowner engagement.
