Anemophily
Definition
Wind pollination. Anemophilous plants produce vast quantities of lightweight, smooth or finely sculpted pollen designed for long-distance aerial transport. Grasses, birch, oak, and pine are familiar examples. High background levels in air make individual grains less specific as provenance markers.

Common questions
Why are anemophilous pollen grains less useful for pinpointing a specific location than insect-pollinated species?+
Wind-dispersed pollen travels far and accumulates as a diffuse regional background present almost everywhere in season, so finding it on an item mainly confirms exposure to open air during that period rather than to any particular site.
How do palynologists still get value from anemophilous pollen despite its ubiquity?+
Its presence and relative abundance still contribute to seasonal dating and broad regional or habitat characterisation when combined with rarer, more specific insect-pollinated or locally restricted species found in the same sample.
