Greg, We have a Seedburo 801 Count-a-Pak Seed Counter that works very well for many species in the collections of Dixon National Tallgrass Prairie Seed Bank. Seed counts for Species with microseeds, and other small-seeded species are estimated by weight, as they are too small to be handled correctly.

Although some species will be too difficult to be handled by a seed counter (e.g. grass seeds such as big bluestem), I wonder if some of the modern approaches (laser counters, ultra-fast photographic counters, etc) that are used in the commercial seed industry could be adapted for prairie seed.
