Management of a watercourse (drainage ditch)
We have moved and inherited a watercourse aka a drainage ditch. It’s 70-80m long and our boundary is at/slightly beyond its far bank. It’s a slope of about 10%. Apparently in times of heavy rain water does flow but I think mostly it’s dry. It’s been neglected and is populated with mostly ivy, brambles and nettles as well as having a lot of soil, stones and garden waste. It’s also largely surrounded by trees. I’d like to look after it and make it a bit of a feature but not sure where to start. I want to encourage a bit of diversity but don’t want it to be too cultivated or make it a lot of work to maintain. Vegetation-wise I was thinking of starting by blitzing it with the brushcutter and digging at least some of what’s there out, and/or maybe do some selective weedkilling. That’s about as much as I have thought about it so suggestions welcome.
