Family Scientific Name: Poaceae
Family Common Name: Grass
Scientific Name: Stipa nelsonii
Common Name: Columbian Needlegrass
General Distribution: Dry plains, meadows, and open woods; less than 7,000 feet.
Propagation Goal: seeds
Propagation Method: seed
ProductType: Propagules (seeds, cuttings, poles, etc.)
Time To Grow: 0
Propagule Collection: Collected in the Yosemite National Park.
Propagule Processing: EASE OF COLLECTION: Collection and reestablishment were carried out by Yosemite National Park; data not available at the Lockeford Plant Materials Center.
METHOD OF CLEANING: (1990) Hand-screened once with size 12 screen to scalp off large inert. Screened3 more times with size 1/12 screen. Cleaned 3 times on small clipper using 1/12 top and 1/22 bottom screens with 20% air. Last run switched bottom screen to blank. Seed does not hammer well as keeps matting and won't push through screen; also doesn't clean well--separation of in-ert from seed is difficult as seed is very light and blows off with it. Did not do well in scarifier to remove awns.
TYPE OF MATERIAL COLLECTED FOR PROPAGATION: Seed.
PROPAGATION METHOD: (Germination in lathhouse greatly increased over ger-mination in greenhouse.) Time-controlled misters used in greenhouse and temper-ature maintained at 65-70§F.
NUMBER OF SEEDS PER POUND: Quantitative values for seed/lb. date of maturity, etc. could not be found.
PERCENT GERMINATION: Quantitative values for seed germination could not be found.
Pre-Planting Treatments: PRETREATMENT USED: None required.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 METHOD OF GROWING: Collection and reestablishment were carried out by Yosemite National Park; data not available at the Lockeford Plant Materials Center.
Harvesting, Storage and Shipping: SEED MATURITY DATE: Quantitative values for date of maturity could not be found.

STORAGE REQUIREMENTS: Longevity of seed unknown. No known special stor-age requirements.

ESTIMATED PROPAGULE STORAGE POTENTIAL: Data unavailable at date of publication.
