First records after the sources of the articles on giant hogweed, Sosnowsky’s hogweed and Persian hogweed. Map: Natural Earth.
Raise a red flag wherever you have seen hogweed. Every flag is a stand someone will have to deal with.
Flags are placed to the nearest kilometre and carry no names, texts or addresses. Your address is not stored; a daily code limits each reader to twelve flags and one vote per flag. Three “not hogweed” votes take a flag down; a flag nobody confirms fades after two years.
Before you go: the field card, protective clothing and first aid.
