Giant Hogweed Locations Map (UK)

Giant Hogweed is known as “the most dangerous plant in Britain”, just lightly touching the plant’s sap can pose a considerable threat to human health. If you want to find out why it’s so dangerous you can read our in-depth resource article on Giant Hogweed or if you want to just get the simple facts then you can look at this Giant Hogweed infographic to help give you a quick overview.

The spread of this invasive species across the UK has become increasingly rapid, it must be stopped. The first step in tackling this invasive species is accurately determining where Giant Hogweed is found. To do that, we need your help!

The Environment Agency, Scottish Natural Heritage, Natural Resources Wales and the Scottish Environment Protection Agency joined forces to create an app that was formally used to tack this invasive and dangerous plant.  Unfortunately due to funding issues, The PlantTracker app is now no longer available from the iTunes App Store, Google Play Store and Windows Store. We all hoped that this would be temporary but now after over 18 months it’s looking like this is not going to happen.

To help continue the collection of this important data for the Biological Records Centre’s iRecord system WhatShed have created this interactive map that shows all the locations for Giant Hogweed sightings in the UK. We have also created a simple form below the map where we ask people who have seen this dangerous plant to enter the details of the sighting so an expert can verify it.

We need to keep collecting the data, we need your help!
