September and the weed cutting season for the River Stour Internal Drainage Board is well under way.
The banks and weed are cut every summer as part of the general maintenance programmes and one of my key jobs is advising on the best cut to maintain the wildlife interest of the channel and work with the contractors Rhino Plant to advise on particular areas of importance such as management for white clawed crayfish.
A small amount of this pond plant found its way into a roadside ditch and has spread quickly. Removing the plant needs to be sensitively managed so as not to cause disturbance or damage to other wildlife. Therefore spraying and vigorous weed cutting is not an option as both these methods would leave ditch edges bare of cover for other species.
Instead the River Stour IDB has approved a programme of mechanical weedcutting followed up by hand pulling of parrot’s feather from the margins. KSCP volunteers have already spent two days wading in the channel or paddling in boats as dragonflies buzz overhead.
An eagle eye is needed to spot the tiniest fragment of plant and a boom net has been installed to catch plants floating downstream. Despite their best attempts all involved know it will take many years of work to combat this plant.
Towards the middle of the month I attended an excellent course in wet grassland management run by the RSPB at their Otmoor reserve. Over two days I learnt about the precise needs of different waders and came away with lots of ideas to take out to farmers this autumn.
Simple changes such as rotovating foot drains can make a big difference and hopefully, by implementing these measures, we can continue to improve the fortunes of birds such as lapwings on the north Kent marshes.
Now all we need is a wet winter to top up the ditches and flood the grassland fields ready for the following spring.
