Thurrock Thameside Nature Park sketches

I heard the very interesting programme, Shared Planet, on Radio 4 yesterday morning, which included a report from the former landfill site in south Essex on the banks of the Thames that is now Thurrock Thameside Nature Park. This prompted me to look out and post these old drawings that I did there on a gloriously sunny yet very windy day last November.
They're done with a 0.2mm Unipin waterproof ink pen and watercolours in an A6 Pink Pig sketchbook.
