Abstract:

INTRODUCTION <br/> Evaluation of new conservation plantings can be very challenging, particularly when unfamiliar species are planted, and when weeds are present. This guide was created to enable land managers to distinguish preferred seedlings from weed seedlings, and determine the success of a planting at an early stage. Species described in this guide are forbs planted in conservation plantings and common weeds in the Inland Northwest region, which is comprised of eastern Washington, northeastern Oregon, and northern Idaho. Native species often mistaken as weeds are also included. The guide provides photos of the desired forbs and weeds at multiple stages, including the seedling and the mature stage, and other photos to demonstrate the species’ defining characteristics. Information is provided regarding the plant’s native or invasive status, priority for control, and look-alike species. <br/> It was not possible to obtain seedling photos of all species. If a seedling photo is missing in this guide, the appearance of the species’ mature leaves or the seedling photo of a related species can be used to help identity the seedling. <br/> Grasses were not included in this guide due to the difficulty of identifying them in early stages. Weedy annual grasses such as cheatgrass (Bromus tectorum) and ventenata (Ventenata dubia) can be problematic in new plantings and should be controlled prior to seeding. <br/> ORGANIZATION OF THIS GUIDE <br/> Plants in this guide are categorized by plant family, and listed alphabetically by genus and species within each plant family. <br/> Taxonomists have recently proposed changes to the organization of plant families; however these changes have not yet been adopted by several local herbariums or the USDA PLANTS Database. All plant family, genus and species names appear in this guide as they appeared in the USDA PLANTS Database at the time of publishing. <br/>
