Richard Stevens Stephen B. Monsen Chapter 19 Forbs for Seeding Range and Wildlife Habitats Forbs are abundant in all vegetative types throughout the Intermountain West. Most are found intermixed in grasslands and as understory plants in shrub and forest types. Forbs provide ground cover, soil stability, community (flora and fauna) diversity, nutritious forage, and are of aesthetic value. Forbs should be seeded in most range, watershed, mine recla- mation, highway, recreational site, restoration and revegetation projects. Many commonly used forbs have been introduced to the Intermountain West and are now under cultivation for seed production. The principal introduced forbs planted on range and wildlands are alfalfa, small burnet, and cicer milkvetch. Lewis flax, Rocky Mountain penstemon, and Palmer penstemon are the major native forbs being commercially grown and planted. Additional species are being commercially grown in seed fields as demand increases. Seeds of many native species are collected from wildland stands but generally are in short supply.
