River Mardyke

This land is owned by Thurrock Council but a tenant grazier grazes his horses here. The area has little bankside vegetation, and the banks are heavily trampled, causing collapsed banks in some areas.

At the time of the survey there were bundles stored on the banks and were suspected to be rubbish from a landfill site and a possible source of contamination.

The area (land use)

The dominant land use for this stretch of river is pasture.

Horses were the main livestock recorded.

Channel characteristics

The river channel consists of mainly silt, and riffles are absent.

At the time of recording the flow of water was sluggish and the channel was 2-5m wide and 0.5-1m in depth.

For most of this stretch the channel profile is variable.

Bankside trees were rare, marginal plants and in-channel plants are frequent. Woody debris was noted to be rare.


The channel has been straightened and man-made enhancements are present along this stretch of river.

Field drains were recorded as present and barriers / culverts are absent.


Areas of trampling / poaching were present and areas of erosion were present at the time of the survey.


Cormorants, Heron, Kingfishers, Moorhens, Green Woodpeckers and Mallards where seen during the survey and a Cuckoo was heard nearby.

Additional comments

A small patch of Japanese Knotweed was found in this area.
