Abstract

Basalt milkvetch (Astragalus nlipes) is a forb (non woody perennial) native to western North America. Basalt milkvetch is a legume forb species of interest for revegetating rangelands of the intermountain northwest; it can contribute high quality feed, valuable seed for wildlife, and nitrogen fixation to help maintain range productivity. Basalt milkvetch has a hard seed coat that makes the seed impermeable to water and difficult to germinate. Low seed germination can contribute to low plant stand when seed is used to plant areas for seed increase. This trial tested basalt milkvetch emergence in response to seed scarification intensity.
