Urban Ecology
That tough little weed mashed flat in your driveway cracks and along foot-worn garden paths is prostrate knotweed, and confirmed sightings like this one help gardeners and land managers track exactly where it's spreading.
Someone spotted a plant called prostrate knotweed in Bozeman, Montana, and other experts checked the photos and agreed on the identification, making it official on iNaturalist. This plant is the low, wiry weed you've probably stepped over a hundred times without noticing, the one that thrives in packed dirt and sidewalk cracks where almost nothing else survives. Records like this build a map of where the plant actually grows, which is useful for anyone trying to identify weeds in their own yard.
