To increase plant materials, wild collections should be sent to native plant nurseries for propagation. Salvaging plants from the wild and replanting them on project sites are described in Section 5.3.3.įor most projects, the collection of wild seeds, cuttings, or plants is not sufficient to meet project objectives. Methods for collecting the stems of willows and cottonwoods in the wild (as well as several other native species that propagate vegetatively) are described in Section 5.3.2. Section 5.3.1 covers how to determine the amount of wild seed to collect, wild seed collection methods, cleaning techniques, storage conditions, and quality testing.

The group of implementation guides in the following section focuses on three types of plant materials: seeds, cuttings, and plants.

Obtaining genetically adapted materials, for example, may involve targeted collections of plant materials near or in the general geographic area of the project site several years prior to project implementation. Obtaining the appropriate species, seed source, and stocktype for a revegetation project requires advanced planning and lead time.
