FIGURE 5 - Maps of population locations and common gardens, with label sizes scaled to (a, c) predicted genetic offsets from GF-X or (b, d) climatic transfer distances for transplanting populations from their home environment to either the (red dot) VT or (red triangle) IH common garden. Only populations with cyan labels were planted in the respective garden in each column. Dark shading is the range of balsam poplar from (Little, 1971).
