A genecological approach was used to explore genetic variation in adaptive
traits in Pseudoroegneria spicata, a key restoration grass, in the
intermountain western United States. Common garden experiments were
established at three contrasting sites with seedlings from two maternal
parents from each of 114 populations along with five commercial releases
commonly used in restoration. Traits associated with size, flowering
phenology and leaf width varied considerably among populations and were
moderately correlated to the climates of the seed sources. P. spicata
populations from warm, arid source environments were smaller with earlier
phenology and had relatively narrow leaves than those from mild climates
with cool summers, warm winters, low seasonal temperature differentials,
high precipitation, and low aridity. Later phenology was generally
associated with populations from colder climates. Releases were larger and
more fecund than most of the native ecotypes, but were similar to native
populations near their source of origin. Differences among native
populations associated with source climates that are logical for survival,
growth and reproduction indicate that genetic variation across the
landscape is adaptive and should be considered during restoration. Results
were used to delineate seed transfer zones and population movement
guidelines to ensure adapted plant materials for restoration activities.
