Evaluation studies begin once a suitable number of collections representing the geographic distribution of the plant are obtained. Experiments evaluating the seed quality and production potential of each species is often the first step of this process. Later, field plantings, utilizing plots established by direct seeding and transplants are installed and monitored for a minimum of 2-3 years.
During these field evaluations, plant performance and adaptation data are collected and analyzed. This data is used in selecting populations of native plant species best suited for restoration use and commercial seed production. Species that are collected throughout a region or in more than one region will be evaluated at a minimum of 6 locations throughout the project area.
