Giant Hogweed

The good thing about Giant Hogweed is it cannot hide very easily! This patch (below) was seen from the road. If this wasn’t spotted, it is estimated that 500,000 seeds would have dropped.

Volunteers can access training, equipment and advice through the project, to find out if you are eligible please enquire at Professional services are enlisted to cover steep banks and islands.

The results of continued control effort on Giant Hogweed have been very positive across the whole Tweed catchment. However, the ongoing discovery of occasional flowering Giant Hogweed offered an opportunity to review the system and make changes. To capture data more accurately, all contractors and Forum staff are now issued with a GPS device to record every plant. From this it was easy to see if survey areas were being covered effectively. Fixed-point photography shots are also taken in tandem with the GPS locational data points, providing important additional data.

Below, before (left) and after (right) treatment: a secluded woodland away from the river, the understory nearly 100% Giant Hogweed. If left untreated, seeds will spread rapidly.


Below: in 2016 there was a big effort towards areas further back from the river, such as railway embankments, footpaths and private gardens. Contractors with climbing experience were enlisted to control steep sections of river bank – a last refuge for plants due to inaccessibility.
