Scientific Name:	Elymus elymoides (Raf.) Swezey
Common Name:	Squirreltail
Species Code:	ELEL5
Ecotype:	USFS, Fremont-Winema National Forest, Chiloquin Ranger District, Chiloquin, Oregon: 4179 ft. elevation
Propagation Goal:	Seeds
Propagation Method:	Seed
Product Type:	Propagules (seeds, cuttings, poles, etc.)
Propagule Collection:	Small lot, 7.15 pounds, hand collected into paper yard bags.
Propagule Processing:	METHOD OF CLEANING: Seed lot is first processed using a Westrup Model LA-H laboratory brush machine, with a #40 mantel, at a speed of 3, to remove seed from stems and de-awn. Seeds are then finished by air-screening, to remove chaff and inert material, using an office Clipper, with a top screen: 3 x 5/16 slot and a bottom screen: blank, medium speed, and medium air. Number of Seeds per Pound: 158,600, Purity: 99.5% (Oregon State University Seed Laboratory Analysis), X-Ray 100 Seeds: 98% Filled, TZ: 96% (Oregon State University Seed Laboratory Analysis), Moisture Content: 7.62%
Harvesting, Storage and Shipping:	Storage: Freezer Storage
Other Comments:	Squirreltail is a challenge to clean due to long reflexed awns, which aid in dispersal, that make this seed "flighty" and difficult to feed into the brush machine.
