River Tyne Hogweed Map

Below is a map showing the locations and status of all known Giant Hogweed (and other invasives). You can zoom in, move around, or click on an item to see more detail. If you want to hide/view different sections (layers), click the box top left or go full screen by clicking the broken box top right. On a mobile it's all better in landscape mode.

We plan to keep this as up-to-date as we can. Please report any sightings or treatment to hogweed@elcv.org.uk
