Species driving Concord’s grass pollen
The modelled data reports grass as one combined index — there is no species-by-species split for grass anywhere in the data, so this page does not invent one. Today’s modelled grass index for Concord is 0.6 (Low), and the 5-day overall trend above shows the shape of the week.
As regional context only — not as today’s readings — in the Northern New England pattern, the plants that typically shape this city’s year are spring birch, maple and oak, summer hayfield grasses and a short late-summer ragweed run.
