Provenance Site Description
To accomplish our two objectives, we conducted two different studies. For both of these studies we collected our samples from a provenance trial of white spruce. Provenance refers to the origin of the species. As such, the provenance trial consists of several blocks of white spruce grown from seeds that vary in origin. More specifically, it is a randomized complete block design with 5 blocks, 5-tree row plots with 2.5m x 2.5m spacing enclosed by two border rows that minimize edge effects. A depiction of a smaller completely randomized block design is included below to aid in visualizing the setup (Figure 1).
