Family Scientific Name: Poaceae
Family Common Name: Grass family
Scientific Name: Danthonia californica Bol.
Common Name: California oatgrass
Species Code: DACA3
Ecotype: J. Herbert Stone Nursery, (for BLM, Butte Falls Resource Area) Central Point, Oregon: 1272 ft. elevation
Propagation Goal: seeds
Propagation Method: seed
ProductType: Propagules (seeds, cuttings, poles, etc.)
Time To Grow: 0
Propagule Collection: Large lot, 170.4 pounds, grown and harvested at J. Herbert Stone Nursery, Central Point, Oregon.
Propagule Processing: METHOD OF CLEANING: Seed lot is first processed using a Westrup Model HA 400 brush machine, with 3 row brushes, a #16 mantel with pins, at a speed of 3. Seeds are then air-screened, using a Clipper Eclipse, Model 324, with a top screen: 1/13 x 1/2 slot, 2nd screen: 1/15 x 1/2 slot and a bottom screen: #5 triangle, and medium to high air, (screen size and air vary by lot). Seed lot is finished, using an Oliver Model 30, Gravity Separator, Speed: 45, Air: 60, hopper speed: 1.5 (speed, air, and hopper speed vary by lot). This final process removes remaining nonviable seed and inert material. Number of Seeds per Pound: 144,000, Purity: 99.52% (OSU Seed Laboratory Analysis), X-Ray 100 Seeds: 97% Filled, TZ: 96% (OSU Seed Laboratory Analysis), Moisture Content: 5.63%
