It’s been an incredibly busy month as we prepare for the start of the survey season.
The month began with a survey of channels on Chislet marshes for the River Stour Internal Drainage Board. We spent a day plotting the extent of the invasive species parrot’s feather which has unfortunately found its way into the ditch system. If left untreated the plant will shade out our native flora, clog structures and block sunlight from the water which will de-oxygenate it and lead to a loss in aquatic invertebrates.
“This is a particularly difficult situation,” said Carol. “The plant has spread rapidly and colonised a large area of the marshes. It is entwined with marginal vegetation along ditches which are a water vole stronghold. The challenge is to find a way of removing the plant while acting sensitively towards other species.”
To deal with this challenge Carol has sought advice from the Environment Agency and Andrea Griffiths, Senior Partnership Officer at Medway Valley Countryside Partnership, who has extensive experience at dealing with invasive species.
“Partnership working is really useful for issues such as this as we can all draw on each other’s experience to achieve a good result.”
The plant was quite possibly unintentionally introduced to the waterways by a member of the public, who may have been tipping excess frog spawn from a garden pond. Unfortunately this has resulted in years of expensive work for others.
On a brighter note we are delighted with the progress of many of the farms we visited this month as part of our advisory work on breeding waders.
Farmers have really taken on board the advice given in the autumn and have performed miracles in making grassland wet in what has been a very dry year. Topping and improved grazing regimes has resulted in much better sward conditions and many farmers have signed up to the funding available from the North Kent Capital Grant Scheme, administered by Kent Wildlife Trust.
Now we are all keeping our fingers crossed for good weather conditions this spring so the hard work can produce tangible results in the form of more wader chicks successfully fledged in North Kent.
Lastly we were delighted to work once again with volunteers from the Kentish Stour Countryside Partnership in order to improve a small, urban stream in Canterbury, managed by the River Stour Internal Drainage Board. This rather sad little channel was full of litter, carelessly thrown by passing motorists and had become dark and shady in some sections and overly managed by neighbouring business’s in others.
Over two days the volunteers cleared around forty bags of litter from the channel, cut back overhanging trees and planted 100 colourful wetland plants outside the Mercedes Garage on Sturry Road. Many thanks to Mercedes for providing drinks and sweets. Serco for removing the litter but mostly to the excellent volunteers who it is always a joy to work with.
