Environmental Impact Research Program: Tall Wheatgrass (Agropyron elongatum). Section 7.1.3. US Army Corps of Engineers Wildlife Resources Management Manual

摘要

A plant materials report on tall wheatgrass (Agropyron elongatum) is provided as Section 7.1.3 of the US Army Corps of Engineers Wildlife Resources Management Manual. The report was prepared as a guide to assist the Corps District or project biologist with the selection, cultivation, and management of suitable plant materials for wildlife and habitat management programs. Topics covered include description, distribution, habitat requirements, establishment, maintenance, and cautions and limitations. Tall wheatgrass is an introduced perennial, cool-season bunchgrass that grows well in saline-sodic soils and subirrigated sites, especially in the West. The species is planted for pasture, hay, wildlife cover, soil protection, and site reclamation. Diagnostic features of tall wheatgrass are described, and the species distribution and region of greatest management use are given. Habitat requirements are discussed, and soil and moisture tolerance are specified. Information on food and cover value for wildlife is presented. Guideline are provided for establishing tall wheatgrass stands on range sites, along rights-of-way, and on erosive and disturbed sites; topics include site selection, site preparation, propagule selection, and planting mixtures. Seed mixtures for restoring big game range are given. Maintenance requirements and appropriate cautions and limitations are noted.
