Every change
How the worst invasives grew, newest first — the same plain notes that go out with each update.
Version 1.1
October 17, 2026- the Scottish Lowlands get their most-wanted list — NatureScot's priorities, like giant hogweed and Himalayan balsam, plus giant rhubarb and two butterburs spreading from old gardens.
- Bohemian knotweed, English hawthorn, yellow flag iris and old man's beard each have a page on how to spot and remove them.
- The Pacific Northwest's worst invasives now go ten deep, ranked by how much harm Washington's ecologists found each one does to wild habitat. Scotch broom, herb-robert and English ivy follow until those ecologists rate them.
Version 0.41
October 12, 2026- chinaberry, Johnsongrass, bastard cabbage, glossy privet and nandina, with how to tell each one and how to clear it without chemicals.
Version 0.40
October 11, 2026- Chicago's most wanted — common buckthorn, Amur honeysuckle, garlic mustard, cut-leaved teasel and purple loosestrife — with how to know each and how to get rid of it for good.
Version 0.36
October 2, 2026- a region page's worst invasives are one tap away, from a chip beside the plant categories at the top.
- two plants went by names that insult people. They're now "highway ice plant" and "Asian bittersweet", and each page says why in a line. Searching "sour fig" or "Oriental bittersweet" still finds them.
Version 0.34
September 24, 2026- Each region's five most-wanted invasives now have a page of their own, with a preview picture listing all five, so you can send a neighbour one link.
Version 0.33
September 24, 2026- every region page now lists its five most-wanted invasive plants, ranked by the local experts' rating, then by how often each has been seen wild. Each has its own page: three ways to recognise it, and real photos.
- Each most-wanted plant's page now says how to get rid of it for good, by hand: the root piece that resprouts, the stump that suckers, and what to do with what you pulled.
- Each tip on those pages now leads with a small picture — a leaf, a berry, a hand pulling, a spade digging — so you can find the one you need at a glance.
